Roland JX-3P Upgrade Kit

via Painting with Sound

"In development is a replacement kit for the Roland JX-3P.

It is still in the early stages but I will keep this page updated with progress.

Ideas for the JX-3P so far are:-

MidiCC support for all parameters
All patches fully editable - possibly extra patches depending on cpu room
Poly and Unison Key modes
Dynamics and Aftertouch via midi
Portamento
Separate LFO and ENV mods for each DCO
Second LFO2 for VCA
Greater speed range and 6 waveforms for LFO1 and LFO2
Second Envelope2 for VCA (Env 1 will be used for DCO & Filter Mods)
Arpeggiator
Midi Sequencer Control
Appegiator and Sequencer Output Midi Data
Patch Editor Control of Parameters
Updates via Internet"

Word is this is almost ready.

Patch Editor - New Hardware Controller

"The Patch Editor has been designed for easy 'live' use with many of the older keyboards with easy to use controls for every synth type. Every active control will light up to make fast changes simple and buttons are colour coded depending which state is active. Each control that is changed will identify itself on the display much as the Roland PG-1000 does.

There was a stage when most of the keyboards manufactures went thought a process of removing all the knobs and replacing them with a parameter driven system. Anyone who has used one will know how difficult it is to use, especially live. When the complaints started arriving some started making plug in patch editors. The problem with these is they only worked on one type of keyboard and were (and still are) expensive and rare. The 'Patch Editor' can be used in place of a PG-200 (with an easily made cable), PG-300, PG-800 and MPG-80 as well as handle midi control of midi and sysex capable keyboards. It includes an internet update system for software changes or new keyboards support, and includes an external input that can be mapped to any continuous control and all the active controls light up to make it easy to use. Currently it is supporting Korg DW6000 & DW-8000, Roland JX-3P, 8P, MKS-70 & MKS-80 and Juno 1. More synths will be added as I can get samples to test and an idea of what models would be useful to players. The Atmel CPU has a lot of space for adding more synth types."
