How to access instruments in multi-instrument and presets sound font

[valnenov]

I have a General purpose Soundfornt https://www.philscomputerlab.com/uploads/3/7/2/3/37231621/weedsgm3.sf2 and want to access the individual instruments in iOS Objective-C but when I load the soundFont with [_synthesizer loadSoundfontFromFileAtURL:@"weedsgm3.sf2" error:&error] and use noteOn/noteOff commands I hear only the 1st instrument in the list. Using the availableInstruments method from MIKMIDISynthesizer.m returns an empty array. Issuing the commands with different channel values (0-15) does not make any difference.

Playing back a mult-track multi-instrument .mid file like https://en.wikipedia.org/wiki/File:MIDI_sample.mid?qsrc=3044#file with [_midiSequencer startPlayback]; does not play the instruments either even though I have loaded the multi-instrument soundFont.

Can someone please let me know how to do this? A working code example will be great:-)

Hi Andrew, any chance you could spate a few minutes for a few lines of code that can help me solve the issues in #318 and #317?
Best regards,
