Quantize audio track

Post by AMusicPlayerPlus »

Dear colleagues,
One of my instruments is Yamaha Motif MO6.
I'm using it as a sound module.
My Cubase has midi tracks and Yamaha Motif MO6 plays it.
Yamaha is connected with MIDI (in/out) and AUDIO (in/out).
So, midi track goes to Yamaha, it plays corresponding sounds, and audio goes recording to Cubase audio track.
I paid attention that obtained audio tracks require quantize.
In particularly it's noticeable when I'm recording drum parts, when in case beats are not the same length is very noticeable.
To quantize the audio I'm using Cubase function AudioWarp Quantize On + Open Quantize Panel then pressing Quantize button.
If anyone experienced the similar problem, when audio track is out of quantize, and there is a need to quantize audio track(s) explicitly?
In case we want to quantize audio track in Cubase 10 Pro, what's the best approach?
If quantize audio track would cause loose of track quality?
Please share your experience.
Thank you!

Is there a reason why you aren't quantizing the MIDI parts before committing to audio?

Once the timing is good, which is much easier to do with MIDI, then you can commit to audio and won't need to mess with it.

The MIDI tracks are quantised.
The problem that sound module = Yamaha MO6 is not playing it with equal beats.
I don't know why. It happens namely with Yamaha MO6. The other synths are fine.

Well this sounds like the real problem that needs fixing - not quantising the audio.

Are you sending both MIDI clock and notes to the MO6 and confusing it, perhaps?

You mean the timing is bad? Are we talking jitter (when quantised notes shift about the beat causing a general lack of timing accuracy), or is it more of a general positive or negative delay?

If the later, is the delay *actually* the MIDI notes, or is it the monitoring of the audio that's delayed (which is a different problem).

What MDI interface are you using? Have you tried a different MIDI interface?

Hm this sounds like some clock drift or MIDI sync issue.. hard to say without knowing the Motif and seeing how and what you send stuff to it, but it shouldn't be doing it I guess...

I do the following settings in Motif Yamaha MO6:

Code: Select all

UTILITY
MIDI->SYNC
MIDI SYNC: MIDI
CLOCK OUT: OFF
SEQ CTRL: IN

So you're clocking this piece of gear and using it's internal sequencer? Is that right?

If so, that's quite a round trip, and the latency in the system will likely be putting your audio recording out of time. But it should be consistently out of time.

That's what I was trying to discover. Often when people complain about MIDI latency it's not the MIDI that's the problem, it's the audio (ie the MIDI is triggering fine, you're just *hearing* the results of that later due to audio latency, nothing to do with MIDI).

That's what a consistent delay would point towards, versus a fluctuating one, which wouldn't (hence the question)...

Actually no.

My Cubase is a master.
It has a midi tracks.
It manage the clock.

Yamaha Motif MO6 connected via Midi In/Out cables is a Slave - it just plays midi tracks from Cubase.

So, Yamaha Motif should have settings:

Code: Select all

UTILITY
MIDI->SYNC
MIDI SYNC: MIDI
CLOCK OUT: OFF
SEQ CTRL: OFF

Yes, that is indeed what I said. You are sending a clock from Cubase to this device. Where are the MIDI notes being generated? In Cubase, or in the device?

The MIDI notes are generated on Device (=Yamaha Motif) .
Cubase has MIDI tracks
