CS-52 - A Yamaha CS-5 'emulation'

[Halon]

Have been wanting to do another 'emulation' of a classic synthesizer so made this. Shure it doesnt sound like the real thing but the architecture is close. I added a couple of extra fearures that you wont find on the real thing. Mind you that it is not done yet but its fully functional. Please tell me if the mod and pitch wheels works properly as my midi keyboard is broken.

Cheers.

That’s a really nice looking and sounding synth Halon. Very easy to see what to do!

I only had a quick look (busy day) but I can confirm the modwheel and pitchbend work fine here.

When it’s finished I’d like to put it on the Flowstoners website, if you’d like that.

Cheers

Great thanks Spogg!

Broken MIDI keyboards is one of the best reasons to have VSTHost. Allows testing of mod wheel, pitch bend, velocity and aftertouch, directly with your computer keyboard. Very cleverly allows applying velocity by clicking on it's on-screen keyboard at different vertical points on a key. Similarly, applies aftertouch by clicking on the top of a key, then dragging the mouse to the bottom of the key.

Great Spogg. Thanks!

Excellent, Thank you Kevin. I actually have VSThost so will remember that next time.

Also, here's something you might want to use. In my research doing some of my Yamaha CS-series emus, I came across Old Crow's Synth Shop which had some scope photos of the unique Saw shape generated by the chip used in (I believe all) the CS-series synths (definitely the CS80), which has a narrow pulse wave mixed with it at low level. I did a stream-mix and a wavetable version of this sawtooth, if you want to play with it; it does sound subtly different from a straight Saw. Maybe Martin knows how to craft one of these in code - that would be cool.

In looking around in your schematic, you can save a bit of CPU by not having both Saw and Pulse oscillators; the Saw can simply be taken from the top Saw inside the PWM module.
Also, that MIDI modulation module (with the aftertouch, etc.) has a couple of green-input de-zips in it that are known to be glitchy - you'll want to replace those with regular stream-input ones.

[Halon]

Thank you Kevin. Really appreciate it! I'll replace the green inputs to streaming inputs instead.
