Hi George!
kAudioUnitSubType_DLSSynth is very old and has never been supported in iOS.
You will want to use kAudioUnitSubType_MIDISynth which is supported on both iOS
and OS X. The underlying synth engine for this type is very close to fully
SoundFont-compatible. Unfortunately we do not have any documents which
describe any missing features, if any. Everything you list below is supported.
Please file radars if you find problems.
