Title: Someone Can Help Me please ?
Post by: kyps on August 02, 2017, 03:55:32 AM
I'm sorry again to disturb you, but Can you explain me why when i play the same note or not,

sometimes the power sound is more higher than the other ??

I tried all the thing ( attack, key sync, trigger, velocity, pressure, in the misc parameter change the"on"  RESET OSC1 and 2, reset all the 16 voices osc1 and 2 ) and it's happen like a big wave.

i recorded it and you can see what's happen in the picture.

It's happen when i start a new preset, even i havnt touched any knob or something.


And i'm asking this to you because on my moog sub 37, they not happens.

Thank you for your help.
(please have a look on the attachement)

It looks like the 16 voices have different levels set, as the pattern repeats every 16 notes (3 rising, 1 small, 5 high, 2 medium, 5 high).  No idea if mine does that, but I'll test it tonight.

Recalibrate the oscillators, seems they've drifted.

Well isn't the moog 37 a totally different keyboard? Expect it and the REV2 to not behave properly.

So on every patch this occurs? Did you reset the keyboard to factory settings?

There's also a way to lower the level of the voices seperate form each other.

true it's not the same, but i mean, it's the first time i've heard this kind of "wave forme volume", not with a moog or other synth ( even p08)

yes every patch, especially when you make a new sound. because the sound is more clear.
I did all the thing we can on the REV2 i think...

It looks like a pattern that reproduces the same volume every 16 notes so it's likely the voices that are not properly calibrated. It's a bit puzzling though. Because if you load the basic patch, it should be a very static sound with an even volume over the 16 voices. Have you tried to reset the global parameters as well ?
Silly question but are you playing directly from the synth or is it triggered by your DAW ? I am asking to check if a midi loop could be involved.

Otherwise, shoot a message to the support, they are very good at helping us out with any issue.

Hey,

Yes i tried to recalibrate and reset all the thing ( with two different OS )

I play with my hand and not with the DAW. IT was just for make a picture.

Thanks for your help everyone.

I have a similar issue with my 8 voice. On an init patch voices 1-4 sound different than voices 5-8. It is most noticeable on triangle and pulse waveforms.

Here's my 16 voice.  I just set up 32 middle Cs in Sonar and recorded what came out, so every note has the same velocity.

I can't hear the variations.

Thank you Bezoblika.

I find an issue, i used a "y" stereo cable. But when i changed and used 2 separetly mono cable, the did the same thing than you.

So,
jburzy01, it's maybe this for you too.
