opcorn is CV nd Gte sequencer. It hs 8 steps. Ech step
hs button, knob nd n LED. One of the steps is lwys
ACTIVE (it hs the cursor on it) nd is routed to the CV nd GATE
outputs. The ACTIVE step is indicted by the step LED with the
highest brightness. The Gte Buttons re used to either set the
GATE (FN LED OFF) or the SLIDE (FN LED DIMMED) for the step.
In combintion with the FN button, the step buttons re used to
djust Popcorn’smin settings.The Step knobs re used to set the
voltge tht goes to the CV Out. The voltge from the knobs is
processed through the quntizer when ctivted.
 CV out
The CV Out is 0-5V clibrted output tht cn crete precisely
quntized voltges (which correspond to the semitones in the
V/Oct scheme). It outputs voltge bsed on the KNOB position
of the ACTIVE step, processed by the quntizer. It cn be lso be
trnsposed, using the CV input.
 Gate Out
The Gte Out outputs 5V gtes on ech ACTIVE STEP chnge. The
Gte goes high only when the STEP GATE is ON (LED of the STEP is
OFF when in GATE MODE). The length of the gte depends on the
Gte Time prmeter. If Gte Time is fully CW the gte holds HIGH
s long s the step is ctive.

NONLINEAR CV SEQUENCER
 Reset In
If rising edge of gte ppers on the Reset Input the ACTIVE
step is set to 1. The only exception from tht rule is when using
the RESET OFFSET feture - see CV INPUT.
 Trier A and Trier B
These trigger inputs re the key element of popcorn sequencer.
On the rising edge of gte or trigger they dvnce the ACTIVE
step ccording to the setting of the TRIG knob, indicted by the
3 bi-polr LEDs. Turning the TRIG Aor B knob (in GATE mode -
see FN BUTTON) shows you green or red lights 1,2,3 or 4 (ll of
them ON). Green light mens the trigger will dvnce the given
number of steps forwrd (e.g. if the ACTIVE STEP is 2 nd there
is green light indicting 3, the sequencer dvnces to step 5 on
the next Gte). ARed light mens the trigger will go the given
number of steps bckwrd (e.g. if the ACTIVE STEP step is 6 nd
there is red light indicting 2, the sequencer goes bck to step 4
on the next Gte).
When the ACTIVE step position goes beyond number 8 it strts
bck t 1.
 FN Button
By shortly pressing the FN button, you switch between GATE (FN
LED OFF) nd SLIDE (FN LED DIMMED) modes.
When in GATE MODE, the STEP buttons re used to ctivte or
dectivte the gtes to be output from the GATE output. In GATE
mode the TRIG And B knobs re used to set the TRIG And B
step settings.
In SLIDE MODE the STEP buttons re used to ctivte or dectivte
the SLIDE (slew limiter) on the CV OUT for individul steps. Also in
SLIDE mode, turning the TRIG B knob llows you to set the GATE
TIME nd turning the TRIG Aknob sets the SLIDE TIME.
While the FN button is held down, nother lyer of fetures is
vilble on the STEP buttons nd on the TRIG knobs. All lbels
in non-blck color correspond to the functionlity when the FN
button is held down.
- Holding down the FN button nd pressing STEP buttons 1,2 or 3
sets the RANGE of the CV Output. You cn choose 1, 2 or 5 Octves.
-Holding down the FN button nd pressing STEP button 4
chnges the mode of the CV Input (see its section).
-Holding down the FN button nd pressing STEP buttons 5,6,7
or8 chnges the settings of the QUANTIZER (see its section).
Holding down STEP button nd then pressing the FN button
will mke tht step ACTIVE in the sme wy s the Jump feture
on the seprte gte expnder module.
 Rane
The output CV rnge of the Popcorn sequencer cn be 1,2 or 5
octves. Hold down the FN button nd press step buttons 1,2 or
3 to select the rnge. 1 octve rnge mens the output voltge
is 0-1 volts , 2 octves 0-2 volts nd 5 octves 0-5 volts.
 Quantizer
The Quntizer enbles Popcorn to output voltges tht
correspond to the exct voltges of semitones (in equl
temperment) in the volt per octve scheme. In other words,
ittkes the input voltge from Step knob nd chnges it to the
nerest voltge tht corresponds to n exct semitone voltge.
The quntizer on Popcorn enbles you lso to filter semitones
inmusicl wy.
To setup the quntizer you need to hold down the FN button
nd press buttons 5,6,7 nd 8 to set wht you desire.
To turn the QUANTIZER ON (led 5 on) or OFF (led 5 off) hold
the FN button nd press step button 5.
To select between chromtic mode (led 6 off), scle mode (led
