Huge adc bug!??

[masterplan]

Good to hear!!

Don´t know if you saw my previous post but this is a related problem that needs to be looked at if you guys haven´t:

Quote from previous post:

Scenario: You want to record a beat MPC-style with a sampler, say Structure.
I.e in a 2 bar loop, overdubbing as you play.

On an audio track you have a sampled horn-loop with a latency-heavy plugin.
For instance Maxim.

You hit rec on your Structure track to record your beat,playing along with the horn-loop.

First time around, fine.
Second time around when you loop back to the beginning, the Structure track is outputting it´s recorded notes without dly-comp.
So the groove is completely f up!

Of course this is how it should work:
What you play in real time should be output without ADC.
What´s being played by the sequenser have to be compensated.

So basically overdubbing anything on an Instrument Track is impossible.

Are you aware of this DTS?

The workaround that I have is to disable ADC or the plug-ins creating the long latencies/delays while recording. You have to disable (not just bypass) the plug-ins.

We already are working on this, though I'm not sure exactly which release it will get into, as it will require significant work and testing.

The ultimate cause is due to the multiple layers of timing requirements - MIDI, machine control, timecode, automation, etc. Prioritization of those events when waiting for input (from CoreMIDI, etc) is what causes the erratic behavior - you can see it occur at any buffer setting and get a different result on subsequent passes.

Obviously this is important and we'll do everything we can to implement a fix asap.

Thanks DTS . I obviously would like a fix sooner rather than later.

The 7.4 issue which might be related, only happens if you have left the track record armed and then play. PITA but not half as bad as this.

Yes, this is part of the same issue and I found out today that the work for this was already in progress, but it's one of those that is a rather large undertaking and effects several areas of code.

Not really much of an excuse, but I wanted to at least give you a little background to explain why this issue is still around...

Yeah, there's been some trade-offs that have had to occur with ADC over different versions. It's a bit of a balancing act with ADC and all the different areas that need accurate timing, but we know what needs to be done and my discussion with engineering today has me confident that we're on the right track for a fix.

That's great news!!!!!!!!!!!!!!!!!!!!!

Then we can start to make music again!

Sweet!
Thanks for chiming in DTS!
I will provide free Red Bull for the engineers so they never need to leave their work until this is done!

A couple suggestions to work around this for now, besides the ones I already gave.

You could bound the high-latency tracks to a new track, then deactivate the high-latency tracks and use the bounced track as a reference.

If you don't have a ton of plug-ins that you need to hear, you could use AS to apply the effects to a new playlist copy of the high-latency tracks and then disable the plug-ins.

In the event that the plug-ins are not critical to the reference mix, just disable them when tracking MIDI.

Thanks for the suggestions.
But just knowing that even with low-latency plug-ins somewhere, the groove that you recorded will not feel the same when you disarm the record button.

So get the whip out and get the engineers to work!

I can only imagine that it is an absolute nightmare to fix. I appreciate the fact that you guys are working on the issue.

I'm with you P!!

But hopefully they're "on to it" twenty four seven!!
