Hello

Just trying to get my head around why the two LFOs in a Mu-Tron Bi-Phase are so different - they both put out square and sine waves.... it has been mentioned on the other forum that one is voltage controlled. I’m still wondering what the purpose of this is.

Thoughts / help please? Why? Because I'm planning on modding a Phase II to have square and sine wave as options, and I would like to understand more about what is going on in the Bi-Phase.

EDIT / ANSWER: Turns out the more complex one is voltages controlled, which relates to the setting where the expression pedal controls the LFO rate.

Andy
