Huge adc bug!??

[masterplan]

Yes it would be great to know that Digi know this is quite a big issue for people making music.
Less noticeable with low latency plugins but still a HUGE issue when you cant trust what you just recorded!

Come on Digi!!!
Get of the playground that Apple and Steinberg are dominating already and get back to the pro-world where things work!!

6. Record something by playing on BOOM from your keyboard.

6.5....DO NOT QUANTIZE!!

7. Everything you just recorded WILL END UP LATE!!


Please DIGI this is not something a PRO program should do!!


This means that everything you record with audio instruments will be wrong!! And even if it's just a matter of like 10 samples it's still unacceptable!!!

DIGIDESIGN!!!!!!....are you listening!!!??




Create an audio track. Create a software instrument track. Insert a latency demanding plugin like Maxim (insert 2 or 3 Maxim to really experience the bug) on the audio channel. Now open, for instance, boom on the software instrument track. When you now play boom you'll have latency....right! But when you press rec the ADC is bypassed on that channel.
Now try to record a simple bd/sd thing from your keyboard together with a click.
When I does that!!.....what I hear when I play....is NOOOOT what comes down on the BOOM track. Everything I play is delayed when recorded.....by the amount of latency the Maxims are creating.

Thank you so much digi!....do I have to go back to version 7 or is there a major fault on my new Intel mac with pro tools accel 2??

Can someone help me with this!?

Tried this on my system (Intel Dual-Core, HD3 Accel), everything plays in sync, in fact when I flip the phase on the audio channel, it nulls perfectly with the Boom track.

Did you remember to assign an audio input to the Instrument track.....?

This is not about comparing an audio track with a vi. The audio track is just there to insert a high latency plugin. Nothing else.

Record Boom on the instrument track referencing the click plugin

Play back Boom and see if it is the same as what you played.

Both Muhis and I are seeing the midi recorded as way late. Its as if ADC is compensating incorrectly.

The reason it is so obvious is that there are hi latency plugins in the session

Try this and see

thanks

I see. Same thing happens here. Hmmm. Not good. According to the manual (page 865), Pro Tools are supposed to shift back the Midi after a record pass. Surprise: It doesn't.

I'm on 8.0cs3

Thanks Stein

This goes back the cs3 at least

DTS where are you

I don't know if this is a work-around or a feature, but if you enable "Always Compensate" mode on the instrument track by Command-Control-clicking (Mac) the track compensation indicator before recording, the Midi lines up. You have to disable it during playback for compensation to work.

You are absolutely correct Stein but obviously this is not how it should work.

I have read posts about this before. This issue has been around for awhile. I need to go back and check, but I have figured that another work around is to turn off Delay compensation when you record midi. Then it all seems to work.

Well.....at least in 8 with cs 3 and in 8.0.1.

I think I installed the cs3 fix when I first installed pt8.
I'm pretty new in the "pro tools software family". I ran logic
with pt hardware before.

But I can't imagine that the problem came with cs3!

Shure!...but everything else will sound like ???? then.
