YouTuber MIDERA posted this performance on an Oberheim Matrix 1000, using an OS update that you have to manually install with a chip swap! The update seems to be worth the effort though, because it allows you to change parameters while you play. MIDERA does exactly that with the aid of MIDI Designer!
Just messing around with the latest Matrix 1000 OS update version 1.20. This version is really great. You're able to modify parameters in real-time with minimal artifacts in the sound (I didn't really hear any). Plus, it lets you see what the current parameter value is (it moves up and down as you make adjustments). Seriously - it's worth buying from the developer on this one!
MIDI Designer Pro 2 on my iPad was used to tweak settings.
