I found a strange behaviour of my HX Stomp (Firmware 3.11) that I control with an external Arduino-based MIDI Controller (for program changes, snapshots and block activation). The problem does not occur with another (coomercial) Midi-Controller I have, still this is very annoying, as my complete rig is build around this controller AND IT USED TO WORK FLAWLESS until I updated to 3.10/3.11.
Directly after switching the hx on, everything works fine:
Block activation via midi works AND is shown on the HX (blocks greyed out or activated)
Values (e.g. Delay time) can be changed AND these changes are visible on the HX
After a progam change via the Midi Controller
Block activation and value changes still work but are no longer displayed on the HX
See a video here!
Probably, my Arduino controller is struggeling with the changes in the midi implementation introduced with Release 3.10:
New and Improved MIDI Implementation
Helix Floor, Helix Rack/Control, Helix LT, HX Effects, HX Stomp, HX Stomp XL
MIDI Snapshot changes on CC69 that are received during preset loads will now be buffered and executed once the preset load is finished. This means that you can send a MIDI Snapshot change immediately after a PC message to effectively load a preset with a different Snapshot than it was saved with
Bank/Preset/Snapshot Up and Down messages how properly work via incoming FS1/FS7 emulation MIDI messages
FS1/2/3 emulation MIDI messages can now be momentary for HX Stomp (values 64-127 = press; values 0-63 = release)
Stomp switch emulation MIDI messages now work while in preset or snapshot footswitch mode
New MIDI message (Helix Floor/Rack/LT/HX Stomp XL): CC71 engages the MODE switch
New MIDI message: CC 72 value 64-127 = next preset, value 0-63 = previous preset
New MIDI message (Helix LT, HX Stomp, HX Stomp XL): CC 73 toggles between Play and Edit views
Anyway, I will look further into this. Even if this might be related to the Arduino midi implementation, any help is highly welcome. Anybody else have similar problems? Please let me know!
