- ROLAND JX-8P
Ten years ago, Fred Vecoven started a project to upgrade his loved JX10. This turns into a huge project where he ended up rewriting the complete firmware from scratch. Many people are enjoying their new JX10 or MKS70 with his firmware. Due to popular demand, he has ported most of the changes done on the JX10 to the JX8P. The little brother can now benefit from all these enhancements!
New features
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 tone parameters individually, including the "patch" parameters.
midi cc support : allow edition of all tone parameters with midi cc.
fast bulk dump/load : 1-2 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)
flash module provides 32 internal banks (total of 32 x 32 tones = 1024 tones!). Preloaded with hundreds of tones.
M16C and M64C support : provide one or four extra banks of tones.
Import mode to load existing internet "dump" files directly into a bank.
Controls any tone parameter can be assigned to the edit slider during play mode [coming soon !]
PG800 and mini-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...)
Arpeggiator
Now available! See release notes and download section (version 5.04 and up).
Chord mode
Now available! See release notes and download section (version 5.05 and up).
Availability
The new OS is available in flash module only (code is too big to fit in an eprom). The module provides 32 banks of tones and can be upgraded by sending a midi file. Eventual bugs (since the code is newer than the Super-JX one) are fixed as soon as being reported. New suggested features will be considered, contact me for more info!
The module is priced 99€ (+ shipping cost). It comes with a new eprom B. Installation is as simple as removing the old eprom and plugging the module. No soldering required. Please contact jx_sales@vecoven.com to order. Please download the manual for more information. When ordering, you will need to specify if your JX8P is an "A2" or "A3" version, see the manual for details.
Soundtrack - is the best patch on this synth. Gorgeous pad!
I just ordered mine for a JX-10 yesterday- can’t wait for it to come in!
Where did you order it from
Well done, great song! I already have the new OS for the 8P, but haven't got the PWM yet. My MKS-70 is fully fitted though, and accompanied by the wonderful MPG-70!
Thanks a lot. I’ve got a fully Vecoven expanded JX10. The PWM upgrade was extremely difficult to install, because of the very complex wiring. In comparison the new PWM upgrade (working for JX8P and JX10/MKS70) is quite easy to install.
JX8p is like a CS80... dull and warm and big.
Is the iPG800 ipad controller app compatible with the vecoven mods on a JX-8P? The app developer's website and info on the app store seems to be from 2017, and expressly says it works on a vecoven JX-10 super, but says nothing about the JX-8P. That'd be great if so - I see the ipad here in the video. Hence the ask. Cheers!
It works for most of the parameters. You won’t have the new PWM parameters though.
Is it just pulling out the old eprom and fitting the new flash module or is there a series of adjustments to be made on the 8P? Vecoven manual mentions about bootloader etc which İ am not aware of.
The flash ROM is just a swap, for the PWM Upgrade components need to be desoldered.
@@Bernd_Bruening Ok thanks!
By the way, after the rom swap do we make any other adjustment on the 8P or is it simply plug and play? And their manual says that the flash module comes with à Rom B. Does this mean that the old Rom B still stays there?
Yes
@@Bernd_Bruening thanks again!
Hmm, vielleicht sollte ich doch nach einem Jx8p Ausschau halten. 🙂
Der Kleine gewinnt durch das Upgrade mächtig dazu.
