Dark rift faster lfo??

[Riccardo Turacchio]

Hi folks
I just finished to build this wonderful pedal
and I'm really happy with the sound
It's not even so dirty if if you keep the feedback max at 3 o clock
one thing that I would like to try is the possibility to increase the rate of the LFO to audio range and wire the wave form to the switctch of the input jack so that when nothing is plugged the pedal can be more like a noise box
Maybe a capacitor and a switch to select from standard to audio rate....
Anyone tried already?
Suggestions?

I recommend breadboarding it to see what happens. Driving the PT2399's VCO input with an LFO or external signal is a bit tricky. The PT2399 fixes the VCO input at 2.5V. The current drawn out of the VCO pin controls the internal clock freq. Draw too much current and the clock osc latches up.

I will probably have to build a small converter box to use external modulation with my pedals .....circuits using the fv1 have also voltage rate of 3.3volts so....
A voltage divider + diode to protect from reverse polarity and a pot for attenuation ...more or less that's the plan.....
