I've composed a song, with a real tracks style, then input melody. When I play (using Coyote WT for midi output device) everything is played through speakers. When I render to wav or mp3, only the realtracks are recorded.

Any advice?
Windows 10 64bit BIAB 2021 64 bit
Midi/audio driver options:
No midi/sound input
No MIDI/sound output
synth/card not listed
x use VSTi/DXi synth
x route MIDI thru to MIDI driver
GM2 support

Can you upload the file to allow us to take a look at it? Oh, wait I see this is BIAB 2021 - sorry I can't help with that.

Yes, but others can give it a try.

OK. I discovered DAW drop station.
I can drop midi track in drop station, then render.
Can also drag master in drop station, then render.
