I've got the MAS dev kit, and it's very nice, lots of detailed doc and examples. Getting SC sounds to run as a plugin should be quite easy. This would also motivate me to write SC plugins, instead of MAS or VST plugins. Also, with SC 3's amazing graphics, one could really go to town on plugin interfaces. Running SC objects inside another host program also neatly solves the sync issue, both for MIDI and Audio. - - In the absense of the above, support for ReWire instead.

in *customInit I've initialised them :

//sync is one pulse per bar (default is 120 bpm)

//localSync is 16 pulses per bar (4 pulses per beat)<= BR> this.localSync =3D = LFPulse.ar(120/15, 0.5, 1.0);

the idea is that these pulses can then be used to trigger various events th= us keeping them in sync

Making the pulse a classvar in the MixerPlayer class means it's there for any lib items to lock onto. Still get crashes though when all seems fine - usually adding a new lib item or changing tempo (another classvar) Cheers Jem The option of syncing via midi to another setup might come in handy. ------------------------------ Date: Mon, 02 Oct 2000 08:46:37 +0900 From: Tomonori Yamasaki <---@---.---> Subject: MIDI time code play({ k = MIDIOut.new(1); t = Impulse.ar(96); //s = PulseDivider.ar(t, 12); //8 per sec //h = PulseDivider.ar(t, 48); //2 per sec //l = PulseDivider.ar(t, 2); //half //i = PulseDivider.ar(t, 84); //every 7 beat //j = PulseDivider.ar(t, 36); //every 3 beat TSpawn.ar({ k.write(1, 1, 16rF0, 9); nil}, 1, nil, k); this is what I use. ------------------------------ Date: Tue, 03 Oct 2000 03:50:21 +0200 From: Julian Rohrhuber <---@---.---> Subject: Re: MIDI time code thank you very much. what do you use to recieve MIDI sync though?
