MIDI timing off when recording enabled

MIDI timing off when recording enabled

Hi all, this is definitely a cry for help!

My MIDI timing for external synths is on spot. Until I wanna record the synth into Logic. Quite unhandy...

Example goes as follows:

1.
MIDI Track 1 (not "External Instrument" Instrument Track)
plays MIDI on Unitor8 Out 1 to synth X. Perfect timing.
2.
Audio Track 1, Apogee Input 3 from console direkt out for recording the synth.
Still perfekt timing.

NOW:
Set Audio Track 1 into record mode: timing is gone!
I'm not even recording, just enabled record in the channelstrip.


Some more infos:
I recognized that as soon as the little r is red, I've got something playing on Unitor out 4 or 5 or both. But there's nothing else playing from the arrange, nor is anything connected to the Unitor inputs.

I found a workaround: when the MIDI track that's playing is selected, the timing is fine. As soon as i select ANY other channel, buy buy timing.

Any hint is highly appreciated!

Lives for gear
Are you running any softsynth tracks? (any plugs on the softsynths)?
Have you got plugins on your audio tracks for recording the external synths? Bypass them.
Do you have any plugins on the stereo output? (usual culrpit) - bypass the plugs and see if there's any difference?

Are you using software monitoring instead of letting the Apogee do it?? Software monitoring is going to be latent and will make things sound off and out of whack depending on your buffer settings and sample rate. Not sure about the activity on channels 4 and 5 though. Are you maybe sending MIDI clock to those ports from Logic?? When you use it to send MIDI clock, you'll get constant activity on every channel thats getting it, whether its playing a synth or not.

Thanks for your reply and sorry for being late on my side...

No plugs, plenty plugs... no difference. Plug Ins on an outputs sometimes create timing problems, but that's usually latency. My timing issue is much more random. Think "really bad drummer"...

Same here, thanks for your reply and sorry for being late on my side...

I will check my monitoring settings, thanks for the hint!
I usually don't monitor at all (to avoid latency while modulating the synth) and simply trust my recording settings as there is no "real" player involved and it is extremely rare that something's not working correctly.

I don't send MIDI clock from Logic unless I absolutely need it. If so, I send it to ALL ports as this generally creates better results. I usually use an external clock (E-RM Multiclock) that is getting an audio timecode.

The additional activity on the other outs is totally random. Sometimes it's one, sometimes multiple outputs and the only thing I recognized is that when there's any activity the timing is gone. As if logic would send tons of MIDI data that's piling up..

Maybe my Unitor has an issue. Used it constantly for just about 20 years... But than again, it work's perfectly as long as I don't record audio?!

Hmmm the problem with the Unitor sounds rather odd, I wonder if it is going bad?? You can always try and reinstall the drivers. They get installed with Logic I believe, but you can find the Unitor Family Driver by itself on Apples site and try reinstalling it. Ive been using my AMT8 for just about as long hehe. Still works solid as a rock, Im gonna miss it if anything ever happens to it, but I guess it'll be time to go back to an all MOTU rig for both audio and MIDI then.
