VMG-01 Sample Delay

[ravisoni]

I don't understand too much on the technical side of things, but with PDC coming to Reason, will there be a need for something like VMG-01 sample delay?

Yes, when you want to add a small delay, also not everything is compensated for so you may want to add this manually...

Note: the VMG-01 is not compensated.

It can still be useful if you're using delay-causing effects inside a combinator that contains several channels using one of the rack mixers (or an audio spider) instead of routing them out to separate SSL channels.

CAN You use this to compensate polar ? if so how
i want a alternative to another tutorial i see thank you

You can use regroove mixer to negative delay (make earlier) the midi timings of notes, maybe also audio.
Using the slide i think. I don't use/need it much.

I'm reading latency on zero latency devices.
Testing Mclass compressor at 44.1Khz and 256 samples it writes 192
at 1026 it writes 960.
The same reading goes for all other zero latency devices.
Is it normal?

Do you have a different result with having "Render audio using audio card buffer size setting" checked/unchecked?

There is this article:
https://help.reasonstudios.com/hc/en-us ... what-s-up-

I noticed that the latency measured with VMG-01 is different from the value for "Delay compensation" in the mixer channel, even without the LED for non-standard routing being lit when new audio rendering is activated (box checked).

The first questions I can think of:

1) Does VMG-01 measure incorrectly with the new setting?
2) Do plugins report incorrectly to PDC with the new setting?
3) Does PDC display a wrong value in the mixer channel?

It's definitely an interesting topic.

Did you already get in touch with someone? Reason Studios or Norman?

I use VMG-01 quite often. And when I do it's not for latency compensation.
Sometimes things just sound better being slightly behind the beat.

I really should check out TS-1 Time Slider, which has both "sooner" and "later" options.

Nope. Not contacted anyone
I didn't read that article, thanks for the dial-up.

1) I guess it's working fine with new settings, it confirmed what my ears were at.
2)That is a good question. The point is they are all out! Only line mixer and RV-7 had no issues.
3) Again, no clue. I need a method for debugging this I don't have.

I reported to Normen and he confirmed it's 1)

What I found out is you can do in order to get correct results from VMG-01:
A) do not use new "buffer size setting" and use any buffer size you want.
B) use the new "buffer size setting" but only use a buffer size of 64 samples.
C) use the "buffer size setting", use any buffer size you want, but do some maths with the result:

Code: Select all

Result of VMG-01 + buffer size sample value - 64  =  correct result 

(e.g. is your buffer size is 512, VMG-01 adds 448 to the correct value).

I mainly use it to delay soft synths inside Reason to be in time with my hardware ones. I could also nudge the midi clips slightly but I find it's easier to dial in the appropriate amount of delay once and work with perfectly aligned clips when arranging, rather than continuously making sure all the tracks are slightly ahead/late that need to be.

Uhm.....

I don't think this is correct, but if Normen can share with us how he managed to get the buffer size as a variable into the RE then I'm cool.

I know that this device is quite old, so is it possible it was available once and has just been removed from the documentation?
