Express Checkout


Note that the above picture shows a typical kit. The actual kit supplied may differ slightly depending on the model it is to be fitted in.

This retrofit kit for the Roland Jupiter-8 adds the following MIDI control:

For incoming MIDI:
Any MIDI channel can be selected
Notes (MIDI note numbers 36 - 96) - transpose possible
Program change (numbers 1 - 128) where 1-64 select whole/upper & 65-128 select lower when split
Pitchbend - (bends up and down with the same range as set for the bender wheel)
Mod Wheel
Filter cutoff frequency (of low pass filter)
Arpeggio clock can be synced to MIDI clock
Auto tune request
The following controls can also be controlled by MIDI:
Hold lower, hold upper, dual, split, whole, manual, and patch presets 1-8

By default:
pitchbend is controlled by pitchbend messages
mod wheel is controlled by Mod Wheel (CC#1) and also by Aftertouch messages
filter cutoff is controlled by CC#16
Volume is controlled by MIDI volume (CC#7)
Sustain is controlled by Sustain (CC#64)

however, any controller or aftertouch or velocity can be mapped to control other things so for example velocity could be mapped to control volume.

For outgoing MIDI:
Any MIDI channel can be selected
Notes (MIDI note numbers 36 - 96) - transpose possible
Program changes 1 to 61 can be sent using a button press followed by a key press
No other MIDI can be sent - the retrofit is primarily intended to allow the synth to be played from a MIDI master keyboard or sequencer.

MIDI In, Out & Thru sockets
Push button (for programming the MIDI setup)
Setups are stored in non-volatile memory (Eeprom)

The kit comprises the following items:
Circuit board - fits inside the top section of the Jupiter-8
Small pack - contains DIN sockets and mounting hardware
Large pack - contains cable assemblies
User instructions - How to change from default settings and general instructions
Fitting instructions - step by step fitting guide plus diagrams of where to connect what

All kits are fully checked and tested before despatch

Note: Our retrofit kits are not intended for installation by the end user. They should always be fitted by an experienced synth engineer.
