Hello, I've been writing an application working with ALSA's MIDI sequencer middleware, and I've been trying to abort playback of a MIDI file by calling snd_seq_reset_pool_output followed by snd_sync_output_queue. The hardware device (a player piano in my case) is silenced, but snd_sync_output_queue still blocks for roughly the amount of time it *would* have taken for all the events to be played out - almost as if there are "zombie" events that don't play, but are still pushed out according to their timing. I realize this is a thing with little to no use, and therefore little to no developer attention, but I'm desperately trying to improve the possibilities for hardware MIDI file playback on Linux. Is this something someone would be remotely interested in exploring? Thanks, Phillip A.
