Roland Super JX Upgrade by Vecoven & Protoype 16 x M64c Cartridge Memory Bank by Guy Wilkinson

This one in via Guy Wilkinson on The MATRIXSYNTH Lounge. That's his JX-10 pictured to the left.

Guy on the upgrade: "It is simply brilliant. I thought all the switches were "end of life" and bought new, but this total rewrite fixed it because the tasks all run more efficiently and snappier, sysex is fixed totally but is not compatible with the old style midi dump, so I protyped a "super cartridge" loaded using old sw then switched to Freds and dumped out all out to cakewalk. Sysex now is quick & seamless from your DAW. There is an ipad PG800 app that works with it too using the mks70 setting. Makes the instrument feel "finished", it took him a long time to rewrite and is working on other stuff, one of which is the PWM modification, extensive voice card rewire but should really unleash the JX/MKS70. Other great features he implemented are arpeggiator instead of sequencer and assignment of any parameter to the controller sliders......nice"

Details via vecoven.com:

"In a nutshell, the rewrite provides:

New midi implementation

- each parameter is now OFF/RECV/SEND/ON, allowing fine control of what gets sent and what is filtered.

- sysex support : allow edition of patch, tone A and tone B individually. (No need for M64 cartridge)

- fast bulk dump/load : 4-5 seconds to dump everything. Can dump to/from cartridge and internal memory.

- edition of parameters (patch and tones) sends sysex, so all editions can be sequenced. PG800 is also supported here, so editions made from the PG800 can also be sequenced.

- copy from/to cartridge to create a full backup of the internal memory (all settings are now copied to the cartridge or restored from it)

Controls C1 and C2 enhancements

- any tone parameter can be assigned to C1 or C2
- any arpeggiator parameter can be assigned to C1 or C2
- C1 and C2 can be used, in tone edit mode, to modify upper/lower tone parameter. This allows quick editing of - tones for those who don’t have a PG800.

Arpeggiator (JX10 only)

- 8 arpeggiators 'patches'

- internal or external synchronization

- supports up, down up/down, played and random notes ordering

- various arpeggio types

- velocity setting (fixed or played)

- note duration (1-15 or legato)

- use lower split point to control which notes are arpeggiated

PG800 support
New display options
- control whether updates from sysex, pg800 or controllers are displayed temporarily on-screen

Compatibility mode
- allows to disable new features for full compatibility with old software (for example, sysex changes made to tone A can be redirected to the currently selected tone, etc...)

Test modes
- test hardware controllers (voices, A/D controllers (aftertouch, bender, C1/C2), keyboard)

- test memory chips

For MKS70 owners, please note that the MONO mode (one voice per midi channel) is NOT SUPPORTED in this release."
