Hi,

I make a simple csd based on trivial OTA formulas,
but it is too simple ! It does not sound like my hardware filter. 

May be i will inject sine signals to the hardware filter to measure the
amplitude and phase output for several setting of frequency cutoff and resonance.

A lot of work....


Best,
René

My experience is that with hardware 4-pole filters, it's not a matter of being
hard to make, but it takes some work to keep them stable. Doing a 4-pole LP
Curtis,... I'll have to try that one. Got an orch/sco- file I can try out?

Hi,

Thanks a lot for this video, it is wonderful.

I fan of Berlin school style music and Space music, all made with synths,
I don't know that Vince Clarke have a so huge collection of hardware synths.

I still have an old Sequential Circuits Six-Track 610 and i am trying to emulate it
with csound and Qutecsound.

Really not easy to make a csound 4 poles LP Curtis filter!!!

Cheers,
René
