Description

PLEASE NOTE: Installing a retrofit kit is a skilled job which should be undertaken only by a competent synth service engineer or installed by us at our premises in Tadworth, just outside London.

Note also that retrofit kits are always built to order after your payment has been processed. It then takes us up to 10 working days to build and test the kit before we can despatch it.

Retrofit Kit

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.
