Introduction
Thank you for purchasing the Polyend Seq. We at Polyend have invested a lot of
our attention, time, and hearts in crafting this instrument in order to make the
experience as creative and enjoyable as possible for you. We must admit that it’s
a rewarding process that gives us a lot of pleasure too. It is our hope that this is
immediately noticeable for the users of our products, and something that you’ll
be able to feel as soon as your new Seq unit is running. We did our best to bring
you a refreshing approach to classic MIDI sequencing in this a state-of-the-art
and modern instrument. We hope you’ll enjoy it as much as we enjoyed making
it. Have fun!
The Polyend Seq is a polyphonic MIDI step sequencer designed for spontaneous
performance and instant creativity. It was made to be as simple and fun as
possible for its users. Most functions are available instantly from the main front
panel. There are no hidden menus, and all functions on the bright and sharp TFT
screen and are immediately accessible. Seq’s elegant and minimal design is
meant to be welcoming, easy to use, and put all of it’s creative potential right at
your fingertips.
Touch-screens have become ubiquitous in modern times but they often leave
much to be desired. We have strived to make our fully tactile interface easy to
operate while using both hardware and software based setups. Our goal was to
make a dedicated music instrument rather than a general-purpose composition
computer. We’ve created this tool to allow you to get lost in it while still
maintaining overall control at the same time. After you spend some time with
this instrument, you should be able to use it with your eyes closed (or even when
you’re drunk). You will still be able to find your way around. Ok, let us introduce
you to your new sequencer, the Seq!
Sit down, relax, take a deep breath, and smile. Open the box carefully and
examine your unit thoroughly. What you see is what you get! The Seq is a classic
desktop unit. It’s glass-sanded anodized aluminum front panel, knobs, bottom
plates, and handcrafted oak wooden case make Seq rock solid. These materials
are of timeless quality and allowed us to avoid the need for any flashy details,
leaving only elegance and simplicity.
The buttons are made of silicone with specially matched density and firmness.
Their rounded shape, size, and arrangement were chosen carefully to provide an
instant and explicit response. It may take up more room on your desk than
a laptop or tablet, but the way its intuitive interface is designed will reward you.
This probably isn’t the first sequencer or musical device you’ve been using, so
you’ll be able to start fooling around with it in no time! If for any reason you’re
not feeling confident, let us give you some insight on what you’ll be laying your
hands on. Use the provided power adapter or USB cable to turn the Seq on. Start
by simply connecting Seq to your instruments, computer, tablet, modular
system, mobile apps, etc. using one of its inputs and outputs located on the back
panel and get started.
The back panel
The Seq is equipped with a wide array of inputs and outputs. This allows you
to communicate with a wide variety of devices. Seq also lets you feed tracks
with MIDI notes using your other favorite MIDI controllers. While looking at
the back panel, from left to right, you will find:
• A Foot-switch pedal socket for 6.35mm (1/4” jack) which operates as
follows:
• Single press: Starts and stops playback.
• Double press: Starts recording .
• Two independent standard MIDI DIN 5 output female connector sockets,
named MIDI OUT 1 & MIDI OUT 2.
• One standard MIDI DIN 5 thru female connector socket named MIDI Thru.
• One standard MIDI DIN 5 input female connector socket named MIDI In
which can either sync clock and input MIDI notes and velocity.
• One USB type B socket port for bidirectional MIDI communication for
hardware hosts like computers, tablets, various USB to MIDI converters or
for example our Polyend Poly MIDI to CV Converter which also can host Seq
into the Eurorack modular systems.
• Hidden firmware update button, which functions in use is explained in
a section named Firmware update procedure below.
• The 5V DC power connector socket.
• And last but not least, the power switch with on and off positions,
necessary to power up and power down the Seq.

The front panel
When looking at Seq’s front panel from left to right, you will find:
• 8 function keys: Pattern, Duplicate, Quantize, Random, On/Off, Clear,
Stop, Play.
• A 4 Line TFT Display with no sub-menus.
• 6 Clickable infinite Knobs.
• 8 “Track” buttons numbered “1” through “8”.
• 8 Rows of 32 Steps per Track buttons.
The four line display with just one menu level, six clickable knobs, and eight-
track buttons. Then right after them, the corresponding eight rows of 32 step
buttons which taken together are also storing its 256 preset patterns (which can
be linked by the way, so you can create really long and complex sequences, read
more about it below). Every track can be recorded step by step or in real time and
then quantized independently. To make the workflow easier for you we’ve
implemented a mechanism that remembers the last setting given for
parameters like for example the note, chord, scale, velocity and modulation
values or nudges for few seconds. So when you’ll get faster with Seq program-
ming this function should increase your productivity.
The buttons
One of the best things about the Seq is that
anyone with prior experience with a music
sequencer will be able to begin using Seq
without reading this manual or knowing
exactly what most of its functions are for.
It was designed to be intuitively labeled
and understandable enough to start the fun
right away. Pressing a button will turn a step
on and off. If you’ll keep the step button
pressed for a while it will show its current
parameters and it will allow you to change
them. All changes can be applied at any
time, with or without the sequencer cur-
rently running on. Let’s Begin!
Pattern button:
Store and recall patterns by pressing Pattern button followed by a step button.
For example, pressing the first button in track one calls up pattern 1-1, and its
number is displayed on the screen. Patterns cannot be renamed, you’ll have to
remember the patterns by number or visually, but you will get used to that
quickly. Pattern buttons are really fun and inspiring when you’re pressing them
rhythmically in order to jam with different patterns, you might like to try that!
Also we’ve found it as a nice habit to have to backup your favorite patterns by
duplicating them into other patterns.
Duplicate button:
Use this function to copy the steps, patterns and tracks. Copy a track with its all
parameters like root note, chords, scale, track length, playback type, and so on
to another one. We find it inspiring to duplicate and modify the various aspects
of the separate track, such as its length and playback direction to create
interesting patterns. You can also copy patterns by using the Duplicate function
with the Pattern buttons. Just select the source pattern and then press the
destination where you would like to duplicate the pattern.

Quantize button:
The steps entered manually on the Seq grid are quantized by default (unless you
use the step Nudge function discussed below). However, a sequence recorded
from an external controller to a chosen track will consist of those notes with all
the micro-moves and velocity - your “human touch” in other words. So if you
want to quantize them just hold the Quantize button together with an track
button and voila, it’s done. Quantization will override any nudged steps in your
sequences.
Random button:
Our favorite button and hopefully yours as well! Hold it down together with
a track number button to immediately populate a sequence with randomly
generated data. The randomization will follow in the chosen musical scale and
root note and will create unique sequences on the fly. Using Random button
will also apply changes to rolls, velocity, modulation and humanization
(nudge) parameters (more below in the knobs section). You can later adjust the
number of triggered notes of a roll inside a step by holding down the step
button and pressing and turning the Roll knob.
On/Off button:
Use it to simply turn any of the tracks on and off while the sequencer is running.
Press On/Off, then sweep your finger down from the top to the bottom of the
column of track buttons, this will turn off the ones that are on, and turn on the
ones that were turned off at the when moment your finger goes over them.
When a track button is lit, that means it will play the contained sequence.
Clear button:
You can instantly erase the contents of a track by using Clear and the track
number buttons pressed together. You can also use it with the Pattern button to
clear chosen patterns really fast. Make sure you really want to clear a track or
a pattern before you use the Clear function! Unless you have duplicated the
sequence, the pattern or track data will be lost!
Stop, Play & Rec buttons:
Both Stop and Play are pretty self explanatory but each press of Play button
after the first one will reset the play points of all eight tracks. Holding down
Stop, then Play, will commence a 4-beat punch-in displayed by step lights on
the grid. You can achieve the same effect using the foot switch pedal if you want
to keep your hands free for some reason. You can then record MIDI data from
an external controller. Remember that Seq will always start recording from the
top or highest turned on track. Recording won’t overdub the notes existing on
the track already, but may alter them. So it may be a good idea to turn off the
tracks with already existing data or changing their incoming MIDI channels in
order to keep the sequences unchanged. Seq will only record notes on tracks
that are turned on. Once you’ve recorded a sequence into Seq in this way,
you can use the Quantize button to snap notes to grid and make them more
rhythmical, just as explained above.
Worth to mention here that there is no metronome in Seq as such. Yet, if you will
need to use a metronome to catch a good timing recording your sequences, just
set some rhythmical steps on the track number eight (because of the reason
explained above), and send them to any sound source. It will behave exactly as
a metronome then!
The knobs
The Seq knobs are convenient clickable encoders. Their step range is based on
a sophisticated algorithm that was implemented to improve the workflow. They
are precise when you turn them gently, but will speed up when you’ll start
twisting them a bit more. By pushing them down you’re choosing from options
displayed on the screen, and then by rotating you’ll change parameter values.
Use the knobs to access most of the editing features which can be performed on
individual steps as well as full tracks (this allows you to subtly or totally alter
sequences while they play). Most of the knobs are responsible for individual
track and step parameters, and change their options while one of them is
pressed.

Tempo knob
The Tempo knob has a global impact and corresponds to each pattern’s settings.
It can also be used with the track buttons in order to set their advanced MIDI and
clock settings. It’s functions are as follows:
Global parameters:
• Tempo: Adjusts the pace of each pat-
tern, every half unit from 10 to 400
BPM.
• Swing: Adds that groove feeling,
ranging from 25 to 75%.
• Clock: These settings let you choose
from internal, locked or external clock
over USB and MIDI connection. The
Seq clock is a 48 PPQN MIDI standard .
Here you can also enable Tempo Lock
function which locks the tempo of
current pattern for all patterns stored
in memory. This might be really helpful
for live performances and improvi-
sations.
• Pattern: Displays the two digit number
(row-column) which points out on
which pattern you are currently work-
ing on.
Track parameters:
• Tempo div: Choose a different tempo
multiplier or divider per track on 1/4,
1/3, 1/2, 1/1, 2/1, 3/1, 4/1.
• Channel in: Sets MIDI input commu-
nication port to All, or from 1 to 16.
• Channel out: Sets MIDI output com-
munication port from channels 1 to 16.
Each track can operate on different
MIDI channel.
• MIDI Out: Here you can set the desired
track output port with or without MIDI
Clock output. With following options:
Out1, Out2, USB, Out1+Clk, Out2+Clk,
USB+Clk.
Tempo 120.0
Swing 50%
Clock Internal
Pattern 1-1
Tempo div 1/1
Chan in All
Chan out 3
MIDI out Out 1
Note knob
When you press down the Note knob together with any of the track/step
buttons, you’ll hear what sound/note/chord it holds. Seq’s grid isn’t really made
to be played like a keyboard, but this way you can at least playback your chords
and steps that already exist in your sequences.
Track parameters:
• Root Note: Allows you to set Track and
Scale root note from in between ten
octaves, from -C2 to C8.
• Scale: Assigns a specific music scale to
a track based on any root note you’ve
selected. Choose from 39 predefined
musical scales (see the scales chart).
As you tune individual steps, the note
choices are confined to the chosen
scale. Notice that using a scale on
a existing sequence will quantize all of
it’s notes and notes in chords to that
particular musical scale, this means
that if you change the track’s root note,
the note in each step is transposed by
the same amount. For example, if you
work with a D3 root using the Blues
Major scale, changing the root to, say,
C3, transposes all the notes down
a whole step. That way you can keep
your chords and melodies harmonically
“glued” together, even if you weren’t
the best pupil in the music classes back
in school.
Step parameters:
• Note: Lets you choose the desired note
for the single step you’re currently
editing. When you have a scale applied
to a certain track, you will be able to
choose notes from inside the used
music scale only.
• Chord: Gives you access to a list of 29
(see the chord chart) predefined chords
which are available per step.
Root note F#2
Scale Phrygian
Note F#2
Chord –
Transpose 0
Link to –

The predefined chords per step were
implemented because when you are
recording chords into Seq from an
external MIDI controller, they are
consuming as many tracks as the chord
consists of notes. If the predefined
chords that we’ve implemented to be
available per step are too limited for
you please remember that you can set
another track playing on the same
instrument and add single notes in the
steps corresponding to the first track’s
chords and make your own. If adding
notes to chords still seems a limited
option, try to add whole another chord,
maybe this will satisfy your ear.
• Transpose: Changes the pitch of a step
by a constant interval.
• Link to: This is a powerful tool which
allows chaining to next pattern or
between any available patterns. You
can put a link in any step on a desired
track, when the sequence reaches that
point, changes the entire sequencer to
a new Pattern. You can link a pattern to
itself and achieve a short pattern
repetition this way. For example, you
can program it so that when your
sequence will reach Track’s 1, Step 8
you have Seq jump to a new pat-
tern—say, 1-2. Just set half of the
tracks off, the pattern won’t change as
the sequence passes step 8. This feature
is really easy to program and lets you
nest sudden pattern changes, or plug
them in on-the-fly. Link restarts the
sequence and plays it from the first
step. Link also disables note/chord and
vice versa.
Try experimenting with setting different tempo signatures for linked patterns
to speed up or slow down a half, this can bring some really cool sound changes
in your arrangements!
Velocity knob
The Velocity knob allows you to set up velocity levels for each separate step or
the whole track at once. You can also opt to have velocity chosen randomly for
a track, while using Random button. You can choose which CC is assigned to
which track, and also set the modulation level to Random. You can set one CC
communication per track and it’s value per step. But in case if that’s not enough
for you, and you’d like to send more CC modulations on one track and one step
(for example when a note is longer than one step, and you’d like to CC modulate
it’s “tail”) you can use another track, and place steps with different CC
modulation communicate and velocity set to 0. This opens many more
possibilities in case of Seq hardware limitations. But hey, aren’t a few
limitations something we really dig in hardware devices?
Track parameters:
• Velocity: Sets the percentage of dis-
tinction for all steps on the selected
track, in a classic MIDI scale from 0 to
127.
• Random Vel: Determines if Random
button affects velocity changes for
chosen track.
• CC number: Sets desired CC parameter
for modulation on desired track.
• Random Mod: Dictates whether or not
the Random button is influencing CC
parameter modulation on a selected
track.
Step parameters:
• Velocity: Sets the percentage of dis-
tinction for single selected step.
• Modulation: Is responsible for turning
on and setting the intensity of CC
parameter modulation. From No
position, where it’s totally turned off,
which was necessary for some types
of synthesizers to 127.
Velocity 127
Modulation No
Velocity 100%
Rand vel No
CC 74
Rand mod No

Move knob
This knob gives you ability to move your whole existing sequences back and
forth. You can also do the same for every single note. Just press the track button
or the desired step button and twist the knob left or right to change their
positions. Oh, there’s also a cool performance oriented feature - click and hold
down the Move knob then indicate the step/s on a track/s you want to trigger -
nice!
Track parameters:
• Move: Allows you to swipe a whole
sequence of notes existing on a track at
once.
• Nudge: Is responsible for gentle micro-
moves of all notes contained on the
selected track. Nudge disables roll and
vice versa.
• Humanize: Lets you choose if Random
button is adding Nudge micro-moves
for notes in randomized track se-
quence.
Step parameters:
• Move: Allows you to swipe a single
chosen step in your sequence.
• Nudge: Will gently move the step
you’re currently editing. The internal
per step nudge resolution is 48 PPQN.
The nudge is working to the “right” side
of the original note placement, you
can’t nudge the note to the “left” side
in Seq.
Move 0
Nudge -2%
Move
Nudge 0%
Humanize No
Length knob
The Length knob can help you create polymetric and polyrhythmic sequences
on the fly. To quickly change the number of steps in a chosen track press that
particular track button and turn the Length knob or push down the Length knob
and choose the track length on the grid, whichever you prefer. The step lights in
that track will indicate, from left to right, how many steps you’re working on.
Use Length to select the Play Mode or to set the Gate length too.
Track parameters:
• Length: Sets the track length from 1 to
32 steps.
• Play mode: Can breath a new life into
your already funky sequences. Choose
from Forward, Backward, Pingpong and
Random playback modes.
• Gate mode: Set gate time for all notes in
the sequence (5%-100%).
Step parameters:
• Length: Edits the time span for single
edited step (displayed on a grid as step
tail).
Length 32
Play mode Forward
Gate mode 100%
While working with polymetric drum tracks, especially when changing the
lengths of separate tracks on the fly, you'll notice that your sequence as
a “whole” made out of 8 separate tracks will get “out of sync”. And even when
you'll change the pattern to another, the “play points” of your separate track
sequences won't reset, something that might look like your tracks went out of
sync. It was programmed in this particular way on purpose and is explained in
a detailed manner below in the “Few other words section”.
Roll knob
Rolls are being applied to the whole note length. Holding down a track number
then pressing and turning Roll will gradually fill the track with notes. This can
be very useful in creating dance oriented drum tracks on the fly. Holding down
a step button while pressing Roll gives you options for the number of repeats
and the volume curve. Seq rolls are fast and tight and velocity curve
configureable. The most convenient way of deleting an existing roll value on
a step is to turn that particular step off and back on.
Track parameters:
• Roll: When applied to a track, Roll adds
steps with an assignable interval
between them. Roll disables nudge
and vice versa.

Step parameters:
• Roll: Sets divider on 1/2, 1/3, 1/4, 1/6,
1/8, 1/12, 1/16.
• Velo Curve: Chooses velocity roll type
from: Flat, Increasing, Decreasing,
Increasing-Decreasing, and Decreas-
ing-Increasing, Random.
• Note Curve: Pick a note pitch roll type
from: Flat, Increasing, Decreasing,
Increasing-Decreasing, and Decrea-
sing-Increasing, Random.

Using Seq with external controllers
Seq is capable of receiving and recording notes (including note length and
velocity) from various external controllers. To record incoming communi-
cations, simply connect your external gear via MIDI or USB port, highlight one
or more tracks you want to record on, hold down the Stop and Play buttons
together to start recording. Then proceed with playing on your external gear.
Please remember that as we’ve mentioned above, Seq is by default recording
incoming notes starting from the top rows of tracks. Also, note that recording,
for example, a three-note chord will consume three tracks. We know it’s a lot,
that’s why we’ve decided to implement predefined chords which can be placed
on one track.
You can record notes from an external controllers directly into a step. Just hold
down the desired step on Seq grid and send the note. The same rule applies to
chords, you just need to hold steps on few tracks at the same time.
There’s also one more cool trick you can perform! Hold one or more track
buttons and send a MIDI note from external gear to change the root key of an
existing sequence of notes. You can do this “on the fly”, there's no need of
stopping playback. The interesting fact of using this is that it turns Seq into
some kind of a polyphonic arpeggiator, as you can change the root notes for
the separate tracks while they’re on the run!

Meet Poly
Initially when we started works on early Seq designing, we planned a full set of 8
CV channels of four outputs of gate, pitch, velocity, and modulation located on
the back panel. At the same time, we realized we wanted Seq to have a sturdy
hand-crafted wooden chassis. After we prototyped the unit we came to the
conclusion that the beautiful oak texture looks strange with all these little holes
in it. So we decided to take out all the CV outputs from the Seq housing and
made a separate instrument out of it.
What came out of that idea grew up beyond our expectations and became
a standalone product called Poly. Poly is a Polyphonic MIDI to CV Converter in
the Eurorack module form. Call it a breakout module, a new standard in
connectivity which supports MPE (MIDI Polyphonic Expression). Poly and Seq
are an ideal couple. They supplement and complete each other, but also make
out just great on their own.
The Poly is a 22 HP module that is able to fit a vast array of inputs and outputs,
provides the user with the freedom to connect all sorts of sequencers, digital
audio workstations, keyboards, controllers, laptops, tablets , mobile apps and
more! The only limit here your imagination. The inputs available inputs are
MIDI DIN, host USB type A, and USB B. All three of them can be used at the same
time. Poly opens the modular world to a digital world of MIDI and can do magic
together with Seq and all the music gear you already have. Depending on what
you want to achieve, there are three modes you can choose from: First, Next and
Channel. Both First and Next modes are perfect for building your own unique
polyphonic synthesizer. In Channel mode a DIP switch on the back panel lets

you choose between MIDI channels 1-8 or Notes C-G that are directed to
corresponding CV voices.
Remember that your Seq can be the heart of your sophisticated hardware rig,
but will also do great with your favorite DAW. You can even power up Seq from
a tablet or a smartphone using one of many available adapters!
Firmware update procedure
In case of any problems or noticed bugs in Seq, please make sure that you have
the newest firmware version installed. We are doing our best to keep our
products updated and maintained, that’s why from time to time we post
firmware updates which you can find and download from the polyend.com
website in the support section. Don’t worry, the firmware update won’t affect
your patterns and data stored in Seq. To commence the procedure you will need
something thin and long like an unbent paperclip for example. You’ll need it to
press a hidden button which is located on the Seq back panel to allow the loader
to flash the firmware. It’s about 10mm below the surface and will “click” when
pressed, so you’ll be able to feel it. The loader will proceed visibly on the screen
and Seq will restart after the procedure. The loader supports devices with both
macOS (from Snow Leopard v10.6 to upper versions), and Windows (from XP
version thru any higher version). While flashing your Seq try to have your
computer plugged into a power source. After downloading the loader file
proceed exactly with steps given below.
1. First of all, make sure to disconnect the power supply and have Seq to your
computer using USB cable only!
2. Turn the Seq on.
3. Execute the firmware loader file.
4. The terminal window will appear.
5. Press the upgrade hidden button on the Seq back panel, it’s located right
next to the on/off switch, use something like a paper clip.
6. Seq will restart and show new firmware version once the upgrade is
complete.
Don’t sweat in case of any trouble (like for example you’ve skipped the first
step), the whole procedure can be repeated. Problems during the process (like
power shortage) will not brick the unit. The change log and archive versions (in
case you’d need to revert to an older version) of firmware are contained in the
loader package. Currently there is no way to dump MIDI data from your Seq unit,
but you can always easily record all your sequences into any DAW of your choice.
Few other words
There are few more things worth mentioning about our product. For example,
Seq autosaves every slight change you make to your sequences and patterns.
Implementing an “undo” function would have been very complex. Since we
wanted to keep things simple, we've decided not to add an undo function. This
solution, like everything else, has it's pros and cons but we much prefer this
workflow. So many times while working with other sequencers we’ve forgotten
to save our sequences before switching to the next one and lost them - Seq works
in just the opposite way.
Also, we’ve opted to simply name the Patterns with numbers because we
wanted this to be simple. Naming the patterns from a knob, letter by letter gives
us shivers. We think that while working with our instrument you’ll be able to
remember visually where you have patterns stored even after a long time.
After spending some time with Seq, especially while playing with different track
lengths and polyrhythms, you will surely notice the unusual "reset behavior”.
Something that might look like your tracks went out of sync. It was programmed
in this particular way on purpose, and it’s not a bug. Even if we like to program
dance-oriented 4x4 tracks from time to time, we’ve also tried to keep in mind
other music genres too. We love improvised, ambient, and experimental genres
where this function of Seq is really useful. We're so up to the eyes with a music
world dominated by DAW’s and strict grid sequencing, where everything is
perfectly synced up to the bar/grid and always in time, that we wanted to free
ourselves up from that. This is the purpose of why Seq works like that. That also
gives you a unique option to achieve a nice "human touch" effect when jamming
with your patterns. Another thing is that Seq changes the patterns exactly when
a new pattern button is pressed, patterns don’t change at the end of a phrase.
I guess it's just a matter of getting used to it. Yet, you can always restart the
play points by pressing the play button while the Seq is already running.
If you’re not a big fan of this solution, please remember that you can use link to
function anytime on the fly, and then your track sequences will get restarted
and play straight from the beginning. Future firmware updates might bring

a feature of different "reset behavior" modes, and you'll be able to set if you want
Seq to wait for the change of a pattern to the end of a whole phrase, just like in
every other sequencer existing on the market already.
If you’d be into let’s say programming an “acid” bass line and would be looking
to make slides or pitch bends. Legato is usually a function of a synthesizer not
necessarily a sequencer. But you can achieve it easily by using more than one
track in Seq for the same controlled instrument. So here again we have
a hardware limitation that can be easily overcome by some not so usual
approach.
Endnote
Thank you for taking your precious time to read this manual. We’re pretty
sure that you knew most of this before you’ve even started reading it.
As we’ve mentioned before, we’re always into improving our products, we’re
open minded, and always into hearing about other people ideas. There’s a lot of
interesting requests out there about what Seq should and should not do, but it
doesn’t necessary mean that we’re into implementing them all of them.
The market is rich in feature loaded hardware and software sequencers that
can outshine our Seq with many exotic functions. Yet, it doesn’t really make
us feel like we should follow this path or copy existing solutions into our
product. Please keep in mind that our main goal was to make an inspiring and
simple instrument with what you see is what you get interface, and we want it
to stay that way ;)
Sincerely yours
Polyend Team

MIDI implementation
Seq sends out the standard MIDI communicates including transport, ten
octaves of notes from -C2 to C8 with velocity and CC signals from 1 to 127 with
modulation parameter. Seq will receive transport when it is set to external
source as well as notes with nudges and their velocity. Swing parameter is not
accessible while Seq works on external MIDI clock, in this setting, Seq won’t
send or receive swing from external gear. There is no MIDI soft thru
implemented.
The MIDI over USB is fully class compliant. The Seq USB micro-controller is
full-/low-speed On-the-Go controller with on-chip transceiver. It is working in
12 Mbit/s Full Speed 2.0 and has 480 Mbit/s (High Speed) specification. And is
fully compatible with the low speed USB controllers.
