Is there no way to play a midi file and the performance data transmit over USB-C from an iPad to a midi keyboard? It can only play to an SF2 file loaded in BH?
Now I'm trying it with an Sf2 sound file I have loaded into BH.
It does work but I'd like to use a particular synth if it's possible.
If you attach an SMF file to a song, it plays like a recording and renders audio using a local SoundFont file. If you attach an SMF file to a MIDI preset, it sends all its data out to other devices, but you can't control it with the recording controls; it just starts running and runs to the end.
Playing an SMF like a recording but with the data sending to another device instead of rendering locally is on my wish list and I'll add a vote for you.
