The volume levels of the instruments gets extremelydifferent

B.jano

Hello from hungary!

It is hard to explane this problem so correctly, because it seems to be quite complex, and I don't know this system well also, I uses g2 just from 2 months ago. I have a g2 engine, with an expansion card on 2 ghz macbook. The software is a 1.40 g2 editor on Mac OS X.
As I know the problem causes at all of my patches. Often I make a connection, or disconnect between two plugs, or just set the reverb from large into hall for example (or other changes like this), the voice of the whole patch changes extremelly: the instruments volume level gets more loud or still randomly, and the synth's pitch value changes some. Crying or Very sad

Could it be a software or a hardware bug? Or what fail I did?

I hope anyone from you met this problem before, and know the solution!!!!

thanx

Could you post a patch and tell us what we have to do with that patch to reproduce the problem you experience?

From what you write I can think of some causes that I would not call a bug, but I must say the retuning you get sounds a weird to me and I would not know what could be causing this. So an example patch would be helpful here Very Happy

Thanx for this fast answering!!!!
Okay, tomorrow i will post a patch sample to you.

Just post it here as an attachment to a message you send Very Happy

Hello Everyone.

I found the cause of the pitch problem, it is about my uncorrect chaining way at a 3 part seq. It is solved now.
About the volume trouble thing:
I attached a selfmade patch, what i made more simplier for showing this problem more clear for you. There are unused object in it, but dont mind about them, just go to the effect part of the editor, and try to switch the blue coloured reverb from large to hall, or small setting for some times (10 times must be enough). Then you will hear the bassdrum's sound become extremely louder, or stiller. If you wont hear anything, the promlem is only my computer or g2 editor, or my g2 machine.

Thanx for helping,
Jano

I'm at work now where I don't have a G2, but the problem here probably comes from the way oscillator phase works in G2.

Your patch uses 10 voices, which means there are 10 instances of your basic oscillator as well (in the voice area). Each time when the patch is recompiled the oscillator phase of each instance will be set to some random value, meaning that sometimes the oscillators will be more in phase with each other than at other times. When they are all in phase the sound will be very loud, and when each odd one is in anti-phase with each even one the output volume will be zero.

You can do two things, set the voice count to 1 (and maybe add some amplifier module to get the volume up), or when you really need the voice count to be 10 you can sync the instances of the oscillators to make them all have the same phase. To do the 2nd thing the current oscillator will have to be replaced with a syncable one (like Osc C) and then you connect the trigger of the kick envelope to the sync input of that osc.

Hope that solves the issue Very Happy

Okay-okay, that was my bug Smile

I'll try the second way! Thanx a lot! Very Happy
