This retrofit kit for the Roland Jupiter-4 adds the following MIDI control:

For incoming MIDI:
Any MIDI channel can be selected
Notes (MIDI note numbers 36 - 96) - transpose possible
Pitchbend - (bends up and down range dependant on setting on synth)
Mod Wheel
Filter cutoff frequency (of low pass filter)
Volume
Sustain (decay on-off)
Arpeggio clock synced to MIDI clock

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.

Hardware:
MIDI In & 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 in the base of the Jupiter-4
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.
