Real Polysynth

It’s not the angle.

I’ll leave it to everyone else to decide how good this guy’s home brew analog polysynth sounds. This was done pretty recently.

This is a no talk video six and a half minutes long.

From the YT comments:

Hi folks, here’s a short, no-talking demo of a prototype 8-voice analog synthesizer I am working on. What do you think?

The hardware of each voice features two VCOs, a ladder-style lowpass and a state-variable highpass filter, wave folder, and ring mod.

All voice circuitry was made with op-amps, OTAs, and discrete components.

There is one effect, an 8-stage analog phaser.

Virus TI/TI2 is basically the ultimate end-all Polysynth.

Wow! That’s an impressive DIY project!

I’m wondering if he has any product intent with this ?

It does things differently, and it sounds very much original.

I’d hope so, it looks good enough to sell as it is! I’ve not watched the full vid but it sounds good too.

I’ve always wanted to build my own poly, I’m no programmer tho so writing the firmware for voice allocation and key scanning has always been the stumbling block. I did get a 4 voice poly midi to CV converter kit some time ago but I’ve not got around to building it. The plan was to use that as the digital control over 4 voice cards. Maybe one day I’ll get around to cracking on with it all. Major issues with mission creep in the thinking about it stage doesn’t help either!
