I’m trying the MIDI sequencer plugins in Ardour, for example:
“MIDI Step Sequencer”, “B.SEQuencer”.
In an Ardour project, I inserted “ACE Fluid Synth” (with a .sf2 drumkit) immediately after the sequencer.
If I press “PLAY”, everything works perfectly, the sounds generated by the sequencer are OK.
But… when I press “REC” (the key with the red circle) and start the sequencer, the sounds continue to be heard perfectly but no more MIDI messages arrive in the MIDI track, nothing is recorded. Only the Master appears to be active.
To record in the MIDI track maybe I have to add something?
