@silverhead : First, thank you for your reply. But it is possible to control preset by midi, it is explained p59 of the 3.70 pilot's guide in the part "Setlist, Preset, and Snapshot Recall via MIDI". @rd2rk : I missed that part, I will have to accept it doesn't work on my computer - I won't buy and learn another daw just for this feature to function. Thanks a lot helping my closing quickly that dead end quest. Until it work with VST3 or Reaper works with AAX hopefully.

I try to use Native using midi in Reaper, but I can't change presets. The midi track communicates correctly with my track using the FX line 6 native, I can change the snapshot from 2 to the 6th using the event : Control change (CC) channel 1; controller 69, value (5) (and of course using the FX enveloppe snapshot) In the same track, the program change doesn't seem to work. Creating the program event gives me 2 events : CC Bank Select 14 bit (0/32) value 129 PC bank msb 1 / LSB 1 program number 3 Could someone please help me find the correct way to program the preset change ? For a bonus I would like to do it, either by a event added in reaper, or using a knob or a pad on my midi controller, but I don't know how to set the parameters. I already check https://line6.com/support/topic/62426-helix-native-program-change-in-reaper/ Any Idea ?
