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...
