dianoia

Thank you all! That's the solution to my problem. But I didn't find it documented anywhere - I think I have to learn more about the MIDI protocol to understand... Thanks! Jens

Now, I have monitored the MIDI send by Reaper's ReaControlMIDI (which is successfull to change Helix Bank): 0011EA9A 3 -- B0 00 79 1 --- CC: Bank MS 0011EA9B 3 -- B0 20 00 1 --- CC: Bank LS I noticed the "MS" and "LS". My monitored signal was "LSB" - could that be the difference?

Hi, I tried to send value 1, same problem and same monitor output: 013C5ABA 3 -- B0 20 01 1 --- CC: Bank LSB

Hi, thanks for your reply! These are the MIDI-out messages I monitored: CC#60 with value 001 (works for changing Snapshot on Helix): 00019082 3 -- B0 45 01 1 --- CC: Hold 2 CC#32 with value 001 (doesn't work for changing preset bank on Helix): 00020D83 3 -- B0 20 01 1 --- CC: Bank LSB Maybe you can say, what's wrong with the 2nd message? Thanks! Jens

Hi, I wonder why my Helix doesn't understand a midi message I send from Java app, I programmed. Here is, what works and what doesn't: - I can send MIDI CC#32 with value 001 from my DAW (Reaper) to Helix and I can see Helix changing the bank. - I can send MIDI CC#69 with value 002 from my Java program to Helix and I can see Helix changing the snapshot. - I can send MIDI PC#003 from my Java program to Helix and I can see Helix changing the preset. - The only thing, that doesn't work is sending CC#32 with any value to Helix to change the bank. Is there some special information I need to send to Helix to show a reaction to MIDI CC#32-messages? Thanks for your help! Jens
