Re: Playing A178 is hard

2008-01-06 by pfichoux

Dear Gabu, Yesterday, I could play 4 octave in a 50 cm space around the antenna. But playing the higher notes without getting out of tune was almost impossible. I practice a lot playing Beach Boys "Good Vibrations" and it requires 2 octave. A110 CV1 input is 1V/octave. Right ? So

I'll try to explain my problem another way : Suppose you want to play thru a 3 octave range with the simple theremin (A178 CV out to the A110 CV2 input). You'll need to move 8" (20 cm) to play notes in the lower octave (C3 to C4), 4" (10 cm) to play notes in the middle octave (C4

You shouldn't need a vactrol at all. There is a current limiting 100K resistor coming from the wiper (center pin) of the Freq pot. That's the only place the wiper goes, this 100K resistor should be easy to locate. One end of that resistor goes to the wiper, the other end goes to
