You can totally do this analog using a sample and hold and a quantizer. The S&H triggered by a square VCO set to the sample rate frequency will create the stepped voltages and then quantizing them over 5 octaves of semitones gives you roughly 6 bits. There's more fine grained quantizers that can process smaller steps than semi tones and could easily allow up to 8 or 9 bits
Very thorough and informative. I like the content, keep it up.
