get-midi-synthclj

(get-midi-synth)

If the global midi-synth has been initialized, then that's the synth you get whenever you call this function.

Otherwise, takes a MIDI synth instance from the pool and makes sure the pool is more-or-less topped off.

ids->channelsclj

(ids->channels {:keys [instruments] :as score})

Inspects a score and generates a map of instrument IDs to MIDI channels. The channel values are maps with keys :channel (the channel number) and :patch (the General MIDI patch number).
