It seems like my CPU upgrade for the Matrix 1000 doesn't work quite right except on my own hardware, plus it may have a design flaw so I decided to work on a ROM only upgrade until I can get something that works fine everywhere.
So you just have to burn that file on whatever 27C256 32KB EPROM flavor you have, plug it into the Matrix 1000 U804 ROM socket in place of the old one and all should be working fine, hopefully.
Here are the changes it brings:
- Bug fixes made by Nordcore.
- MIDI NRPN parameters editing fix.
- Faster processing of parameter changes that need a modulation matrix rebuild, there's still a small lag but it's much better than before.
- Unison detune, controlled by MIDI CC #94 (Celeste Level), value from 0 (no detune) to 127 (strongly out of tune). It is always active, even in poly mode. Values around 2-6 add a slow VCO-like detune that helps liven up the sound and keeps poly mode sounding in tune.
Keep in mind it's still an alpha version, but there's a much better chance it works everywhere the same, ie. fine as far as I know.
Edit: This version has now been tested on many M1000s, so I think it can be considered stable and production quality.
