[music-dsp] faking oscialltor sync: will this work?

[Markus Sapp]

Hi all,

first I must admit that I am partly responsible for this thread because the 
ES2 was done by Steffan Diedrichsen and me.

But as you will surely understand I cannot tell you too much about the 
algorithmic details.

Thank you!

Can you try to describe in more detail what you don't like about the sound, 
because that would help me to improve it.

;-)

You got it!
