MIDX-20 DUAL USB Host
DESCRIPTION
The MIDX-20 unit has two USB Host ports (USB A so kets), a MIDI IN and a MIDI
OUT (both 5 pin MIDI) port, plus two controller jacks for generating MIDI from
external expression pedals or dual foot swit hes.
There are various pro rammable MIDI routin possibilities between the onne tors.
A USB MIDI (foot) ontroller may ontrol a USB devi e as well as other 5-pin MIDI
equipment.
Another routing possibility is when a 5-pin MIDI (foot) ontroller ontrols up to two
USB devi es (see separate hapter for full des ription of the routing apabilities).
When onne ting a guitar synthesizer with Guitar-to-MIDI onversion an external
synthesizer an be used for playba k.
The unit also has an optional MIDI THRU/MERGE mode, sending 5-pin MIDI IN to the
5-pin MIDI OUT at the same time as other data from the USB devi es is transmitted.
The two USB onne tors are fully Roland/Boss compatible allowing any Roland/Boss
USB devi e to be onne ted for ontrol or playba k. Roland/Boss devi es use a
vendor-spe ifi USB MIDI ommuni ation proto ol. This unit is ompatible with the
following Roland/BOSS Guitar devi es: Katana Amplifiers, GT-10, GT-100, GT-001,
VG-99, GR-55, GP-10 and SY-300.
Both USB onne tors re ognize Fender Mustan ™ Amplifiers allowing the amps to
be ontrolled using MIDI ommands (see the Mustang MIDI implementation hart
elsewhere in this manual).
Any MIDI class compliant USB device may be used with the unit, su h as Fishman
TriplePlay, KMM SoftStep2, Logidy UMI3 USB MIDI Foot Controller, et .
The MIDI USB Host is powered by a regulated 8-12V ( enter negative) mains adaptor
(not supplied) or a 5V Mini USB able via a phone harger (not supplied).
Important:
- The MIDX-20 does NOT support USB Hubs.
- Powering the unit using a Mini USB able dire tly onne ted to a Personal
Computer works, but is not re ommended as digital noise may be
introdu ed.
- The unit an deliver a urrent up to 1.0 Amp assuming the power supply
(pedal board adapter or Mini USB adapter) is rated at that level.

CONNECTORS
MIDIINANDMIDIOUT5-PINCONNECTORS
The two 5-pin MIDI onne tors allow for onne tion of ‘ lassi ’ MIDI devi es in the
ommuni ation stream. The unit provides an optional MERGE/MIDI THRU feature
(enabled with the SET button), whi h will forward any in oming MIDI message from
the MIDI IN 5-pin onne tor dire tly to the MIDI OUT 5-pin onne tor. If there’s a
ollision between USB messages from the USB devi e with messages from MIDI IN,
the message that started first gets priority to omplete before the other streams are
allowed to pass through.
USBCONNECTORS
The MIDX-20 USB Host onne tors allow ommuni ation with two Roland/BOSS
devi es, Mustang™ Amplifiers, or any other lass ompliant MIDI devi es. The
onne tor is of ‘sta ked’ type with an upper and a lower USB slot.
The lower onne tor (LWR) is intended for a devi e ontrolled either by the upper
(UPR) onne tor or via 5-pin MIDI, and annot be re onfigured.
The upper onne tor (UPR) is onfigurable and may be programmed for a se ond
devi e ontrolled by 5-pin MIDI or may be onfigured for a USB Foot ontroller.

POWERCONNECTORS
The MIDX-20 an be powered by:
1. Normal DC pedal board adapter (not in luded) 250mA – 2.0A (8V - 12V DC,
enter pin negative). If the wrong polarity is used the unit will not be harmed,
but it will not work.
2. Mini USB able (5V DC) from a phone harger (not in luded).
When onne ted to most devi es the urrent draw by USB is negligible however the
LEDs and mi ro ontroller ir uitry require a few milliamps. The unit an deliver a
urrent up to 1.0 Amp assuming the power supply (pedal board adapter or Mini USB
adapter) is rated at that level.

CONTROLLERJACKS1&2
Ea h of the ja ks allows you to onne t either a Roland EV-5
expression pedal, a Roland FS-6, or Roland FS-7 ompatible
dual foot swit h. The expression pedals or foot swit hes will
be ontinuously monitored and onverted to MIDI ontrol
ommands.
EXPRESSION PEDALS (ANALOG CONTROL)
Expression pedals ompatible with MIDX-20 require a
10 kOhm potentiometer. The stereo plug TIP is
onne ted to the enter tap of the potentiometer
(Output), the SLEEVE is onne ted to one end of the
potentiometer (Ground) and the RING (Input) is
onne ted to the other end of the potentiometer. At
heel-down position the lowest resistan e should be
obtained between Tip (Output) and Sleeve (Ground)
Re ommended expression pedals:
Roland EV-5, EV-7, Boss FV-500L
DUAL FOOT SWITCHES (ON/OFF CONTROL OR PROGRAM CHANGE)
Dual footswit hes ompatible with MIDX-20 require:
- One swit h to short the TIP to SLEEVE when pressed.
- The other swit h short the RING to SLEEVE when pressed.
The swit hes must be of MOMENTARY type (or the swit h unit
must be onfigured to MOMENTARY mode).
Re ommended swit hes:
Boss FS-6 and Boss FS-7
IMPORTANT NOTE:
For FS-7 use these settings: Polarity = II (RIGHT), Mode = FS-5U Momentary.
For FS-6 set both swit hes: Polarity = RIGHT, Mode = FS-5U Momentary.

In normal operation the LED’s show the following information.
FenderMustang™Br dge
MIDX-20 ontains spe ial software that allows ontrol of one or two Fender
Mustang™ Amplifiers using regular MIDI ommands.
You may ontrol the Mustang™ by using an external MIDI ontroller onne ted to
the MIDX-20 and/or by using expression pedals/foot swit hes onne ted to the
CTRL1 and CTRL2 ja ks.
IMPORTANT NOTE:
If you onne t a Mustang™ to the upper USB onne tor the MIDX-20 need to be in
“DEVICE IN/OUT” mode (the leftmost LED showing RED) for proper operation.
If you onne t a Mustang™ to the lower USB onne tor all of the Upper USB Modes
may be used.

REAL-TIMEMESSAGES
MIDI Clock - When power is first applied, no input is defined as a master and all lo k
messages from both inputs will be passed until one input is defined as a master. The
input to re eive the most re ent START ommand will be ome the lo k master. That
input ontinues to be the lo k master until another input satisfies the above ondition.
Active Sensin - The first input to re eive an a tive sensing message will be ome the
a tive sensing master. A tive sensing messages from that input will be passed to the
output and any a tive sensing messages re eived at other inputs will be ignored. The
input will remain the a tive sensing master until no additional a tive sensing messages
are re eived at that input for a period of a few se onds. Then the other input has the
opportunity to be ome the a tive sensing master.
MIDX-20MODES/MIDIDATAFLOW
As there are three bidire tional MIDI onne tions (2xUSB + Standard MIDI) and two
ontroller ja ks, the flow of data between the onne tors an be onfigured in many
different ways. To over most ases, four modes have been ele ted for the MIDX-20,
sele ted using the SET button. A LONG HOLD of the button will y le through the four
modes and the urrent mode will show on the UPR MODE LED.
LED is OFF – Mode for two USB devi es, UPR is only sending data.
LED is RED – Mode for two USB devi es, UPR is bidire tional.
LED is GREEN – Mode for a USB Controller on UPR, UPR is only re eiving data.
LED is YELLOW – Mode for a USB Controller on UPR, UPR is bidire tional.
Ea h of the four modes may also have MIDI THRU/MERGE ON or OFF rendering the total
number of possible onfigurations to eight. The following flow harts des ribes in detail
how the unit operates in these eight modes.
This symbol is used to indi ate a merge of two or more MIDI data streams.
If there’s a ollision between USB messages, the message started first gets priority to
omplete before the other stream is allowed to pass through.
Note:
The MIDI MERGE mode allows for forwarding MIDI data and daisy- haining several
devi es (or MIDX-20 units) via the 5-Pin MIDI onne tions.
