Simple Audio + Midi Sync?
I’ve got an audio file and the (multichannel) MIDI file that I used to create it. All I’m trying to do is play both of them in sync in Max, but they keep falling out. No loops, no external devices, no frills; just sync. Should be relatively simple, right?
I’ve spent quite a while mucking with changing the playback speed (via weird messages to detonate), as well as changing the rate of the audio playback, but there doesn’t seem to be a ‘sweet spot’. No matter what, they always fall out of sync after a minute or so.
I’m not sure where to start approaching this… As for specific questions:
1. Should I instead be using some kind of click track / transport?
2. Should I be changing the speed of the midi to sync with the audio, or vice versa?
3. Anywhere I can read up on this type of thing? Can’t seem to find anything as straightforward as this on the forum.
I’m on a new MacBook Pro (core 2 duo 2.53 GHz, 4gb ram), in case it helps.
I am also looking for a solution for this problem (multichannel audio via sfplay~ and a separate midi track). I tried to send audio and midi simultaneously to max via Soundflower and the "to Max/MSP 1" setting. I tried to record them via sfrecord~ and different MIDI objects. seq is unusable, because audio and midi drift apart after a few seconds, seq~ is loop-based, which is not interesting for me, detonate ist only for midi notes. I could be using a external sequencer software for that task, but that’s a) an overkill and b) I need a simpler solution for my deployed audio installations.
I am also on a new Macbook Pro. Any help yould be appreciated!!
I found a solution. You can use seq, as long as "Scheduler in Overdrive" and "in Audio Interupt" is activated. After recording a sequence send a "hook 1.00534" message to seq to speed up the playback. It’s better to use hook and not the "start
I hope this helps people with a similar problem.
