Yeah, I am talking about a physical synthesiser. Although the more complex digital synths do require coding. The coding itself is probably easier than you'd think, mostly due to the fact that there's so much freeware out there these days. To add to that, coded/digital components are almost purely optional; there's more than one way to get the result you desire.
Once upon a time I imagined a keytar like that...
Tbh, my understanding of electronics is pretty basic. I'm currently in my first year of study in mechatronics engineering and science (if you didn't know, mechatronics = mechanical + electronics). That being said, I'm pretty good at self-teaching when I have the motivation (which, I'll admit, can sometimes be short lived). At the moment I'm pretty lost - I quite literally don't know where to start. My ulterior goal thus far is to make a simple analogue monophonic synthesiser that can produce sine, saw, square (w/ PWM) and triangle waves with a ladder filter, where the frequency (and nothing else) can be controlled by digital means (MIDI or USB). This will be controlled by a yet-to-be-made Wicki-Hayden MIDI keyboard. Yes, I know, Ive most likely set my sights too high.
I suppose the key point there is that I want to make it analogue. I may as well make the best that is possible (I'm a stubborn perfectionist). I just don't see the point of making a hardware digital synth if the same thing can be replicated on any computer. Analogue is supposed to be better sounding as well. However I do realise that there's a lot that digital can do that analogue can't, and digital is a lot easier due to the number of ICs that simplify everything.
