Hi and welcome to Arturia forums.

Which tutorials use ProgramChange messages?
One shall only use ProgramChange messages if one use Concerts or Playlists in the applications. If you have a concert or playlist with less than 128 presets, then it will stop, when there is no more presets in the list.
If you look at the Browser page, then you'll also see a lot more than 128 presets, and the preset banks can change all the time, so you can't use bank select. You can with concerts/ playlists. So what excactly is wierd behavior and why?
ProgramChange is only 128. Bank select is also 128. That's just how it is, if you look at the midi standards for those messages.
Which synths with advanced preset browsers does'nt require lists to use ProgramChange, if it can use it at all, and which can use Bank select at all? I'm curious to know.
But yes, if the OP somehow send a ProgramChange to each application on a track, then that could cause the preset to go to a certain preset. But i would believe such ProgramChange would first be send when the DAW was running and not at load like the OP tell. But it's good to be aware of this anyway, just in case it somehow could have to do with ProgramChange.
