Spin Semiconductor

Cool filter chip, I'll order one next time I put in for components. I've heard switch capacitor filters can sound a bit different from the common op amp, diode or transistor ladder based filter. It would be worth checking out if you like the sound. If I were doing this I would make each pole fade i...

Hey there! I want to implant them in an 8voices (x3 osc each) semi analog synthesizer I'm working on, and wanna implamant 1Fv-1 for each 2 voices (total of 4 fv-1's) I just don't know how to write the code for it, I found one for 4poles but not for 3/2... Cool, I love analog synths. I run a modular...

those are pretty easy to implement and Im fairly sure you can make one using spinCAD, which is worth checking out and pretty easy to make some nice filters for FV-1 What is your need for them? it this as part of a hardware device DIY thing or are you working on some sort of pedal or product etc? ju...

Hey there, do any of you have a program of a LPF with resonance control for the FV-1?
I'm looking for three separate programs
One for a resonance 4pole LPF
One resonant 3pole LPF
One for a 2pole LPF

I don't how to implement them my self, I'm looking for some one who has a ready to go codes.
