Thanks for the help Pier. I tried the first suggestion loading a preset with Mpres, My, Mx all set to 127. I also had the Mmode set to normal and jack2 set to midi. I connected to the tracker and it worked perfectly. Too perfectly as pressure was working – notes were louder depending on pressure. I didn’t expect this since I set Mpres to 127 (disabled). But it was all working promptly and accurately for about 20 seconds then the indicator light turned white and I was back to where I started: inconsistent note triggering.
While it was working the indicator light was green which is strange since green is not any of the auto-detect jack2 modes specified in the 2.2.1 release. Another strange behavior is how it just automatically changed (even thought I set the jack2 mode to be midi instead of auto-detect). And repeating the whole config change never brought me back to the green success. Just goes straight to white with inconsistent note triggering.
The cable I’m using works well with other midi note sending devices. Midi monitor shows everything working fine over usb. The 20 seconds of success gives me hope that it is possible for my Striso to cooperate with my Tracker. Let me know if you want me to try anything more specific. Thanks
