From f85d733f9dc569bd6b3f37a0a4b8be7b3c783ad6 Mon Sep 17 00:00:00 2001 From: Chris Robinson Date: Fri, 27 Dec 2013 02:59:50 -0800 Subject: Add a method to set and get soundfonts The main purpose of this is to select soundfonts for playback, eventually, instead of the existing method that takes a filename. --- Alc/midi/base.c | 43 +++++++++++++++++++++++++++++++++++++++++++ Alc/midi/base.h | 7 +++++++ Alc/midi/dummy.c | 1 + Alc/midi/fluidsynth.c | 1 + 4 files changed, 52 insertions(+) (limited to 'Alc/midi') diff --git a/Alc/midi/base.c b/Alc/midi/base.c index 6449d7fc..8b498680 100644 --- a/Alc/midi/base.c +++ b/Alc/midi/base.c @@ -124,6 +124,9 @@ void MidiSynth_Construct(MidiSynth *self, ALCdevice *device) RWLockInit(&self->Lock);
