Spin Semiconductor

Hello everyone! I'm new to the forum

I'm thinking of building a audio modulator to control the internal generator. The idea is to FV-1 created a sound sin / square and a triangle in proportion to the frequency and amplitude audio input.

Can you help me with the code? I'm still learning FV-1 and I'm not in a position to write this code. I will be very grateful.

I need three codes separately for sin / square and a triangle.

Best regards to all lovers of the VF-1. The UC is more than great!

Do you mean frequency tracking? I.e., an audio input is being analyzed and a generator programmed in the FV-1 will have the same frequency like the input?

So that was good. I wonder how this is possible using the FV-1
audio signal to control the generator. I tested different solutions with AVR and PIC controller, but I didn't get a satisfactory result.

While I'm not the expert on FV-1 programming, I have looked really hard at all of the available code samples on this site and I have not seen anything like this at all. I won't say it's impossible though. If you do succeed you might be the pioneer in such an application.

I do recall one person said they had developed a fuzz type effect, which had the small problem that it didn't stop oscillating when the input signal went away.

You might be better off working with some 'pitch to midi' or 'pitch to cv' project since the FV-1 is designed to be an effects unit.

I remember this project:

Don't know if it's usable, though.

Also, I think the Korg MS-20 has some kind of pitch tracker that lets you control its oscillators using an external audio signal? Perhaps you can find the schematics and find a solution that doesn't even require programming.
