Hi together,

I have a question for the physicists of you. How can you explain the following thing that I have described in the subject:

Start with a very raw sound-setting:
- Put Osc 1 + Osc 2 to the same waveform, e.g. pulse
- set tune and fine tune to zero, unsison off
- open the filter completely
- remove all modulations.

First play with the Osc-Mix position at 50:50 and then turn to 100 % Osc 1 or 100 % Osc 2: the volume with a single oscillator is significant louder and the sound is more "direct" compared to the mixed position.

So, why is (only) one oscillator louder than two of them? Is there some kind of "wave erasure"? Or is it a "special feature" of the Lead?

Thanks for your answers and have a nice weekend!

Hello Nordlicht and welcome to the forum.

Could this be a case of phase cancellation?

This is a rather extreme situation, but surely the two Osc's are out of sync.
Solution: press the sync button twice (sync on and sync off) and the sounds is two Osc's again.

Thanks - that`s it!

I didn`t know how to sync the two Osc.

Wow, great!

OK, but I just have checked another thing:
I have stored such a clean, raw and via "sync-on/sync-off"-operation synchronised sound/program - but after changing the program (one step forward to the next and back to the stored) - the oscillators were out of sync again (i.e. they were alone a bit louder than the mix of both)

So, it is not really dramatic but obviously you can't store everything...

I don't know what the 'in-between' Program is. The Osc are running all the time! If the new Program has a slighter faster or slower setting of Osc2, it will run out of sync. But why should it return in sync when toggling back? Only Sync will sync...
BTW FM is highly sensitive to the phase of the wave forms...

i dont get it, i have the same problem as the dude above.....if i press sync twice i get ring modulation....

never matter, if i sync the sound always get thin, if sync is off and i use one osc, the sound is fat, if a mix 50% osc, the sound is more unison/detune but not fat as single....

whats the purpose of sync for FAT leads for goa/psytrance? is too fluet

Sync allows you to get a very specific sound. If you enable OSC sync, OSC2 gets synced to the first one (= restarts its cycle when OSC1 starts a new cycle). If you turn the mix value fully to OSC1, having sync on or off doesn't matter, since you're not hearing OSC2 anyway. If you turn the OSC mix fully to OSC2, you only hear the synced wave.

Anyway, page 43 of the manual has more info on oscillator sync.

This video might have some ideas too.

yeah bro i know it, i learnt on the manual...

i just didnt understand about the Two OSC being thin than isolated osc, and the solution would be two press on sync.....
