I am very new to DIY modular synths. My interest is the DIY electronics angle w/ the musical part secondary. As I get closer to building some modules, I have started to think about full MIDI/ Digital control of an analog synth. I like the ideas you laid out here and in your video about maybe making a card based polysynth w/ digital control. I am very interested to see what you do next.

Hey man! Have you ever looked into how organ-poly"synths" from Solina or Hammond work? I personally have a Solina, and have been thinking about using that VCO and divider circuit to do a DIY poly synth. It basically works with one VCO that is divided down and split into a separate frequency per keyboard note. This means it essentially has unlimited voices, because all notes operate independently. You would still need quite a few dividers (I believe 7 or 8) per VCO, but the schematic for that should actually not be difficult at all to implement in a synth with a MIDI connection and a microcontroller/multiplexer instead of physical switches for the keys.
@polykit
9 ай бұрын
Actually, I did looked at it. I own a Crumar Stratus which is exactly that. All notes are derived from a master oscillator for all keys. It uses TDA1008 integrated circuits to divide down the frequency. Problem is that you still need an envelope, voltage controlled filter, VCA etc. for a proper polysynth per voice and this brings the limitation. The Crumar has that six times and a specific set of notes are assigned to one of the voices.

Thank you! No, only notes and pitch bend are controllable by MIDI. There is no DAC to control other parameters. This will be different in the voice card project I made a video about. All parameters will be controlled by a DAC and patches can be stored and controlled by MIDI.

I'd be curious if there are any detectable differences between a DCO and a well tuned VCO.

@@monkeyplusplus there isn’t a difference in the actual waveform of an analog DCO, it’s just digital control. People claim DCOs sound less fat, but that’s due to a lack of ‘slop’, very subtle pitch instability. Particularly in multiple oscillator setups, as the very subtle unison effect of two oscillators with slight drift are perceived as fatness.

Dang it sounds wonderful. Question. I’ve always found synths with larger components (ex oscillators on Jupiters) to sound quite heavy, heavier than miniaturized integrated circuits. (Example. Sound of original Pro One vs Behringer Pro 1) Is this incorrect?
@polykit
Жыл бұрын
I don't think that this would make any difference. In the end it is only a package and the component inside is the same. I would assume in vintage synthesizers component tolerances were much higher than nowadays. Also companies selected specific components out of many to get a specific behavior/sound. This knowledge is most likely lost in modern clones.

I find this super interesting and also during your design phase one can understand why back in the day e.g. the Juno 106 was built this way by Roland. Did you have any look at the Mutable Ambika before building this? It is a more complicated design with 2 microcontroller per voice. On the other hand it is programmable and can be multitimbral. I think it is now distributed by TuneOhm. However I find your design more elegant.

Today I'd say that discrete would include small scale integration ICs. Everything is relative after all. But yes technically in the classical definition discrete would mean individual components. If you were to make something like this like that it'd take up a warehouse. Which is why so little is made discrete today.
