> When your analog synth has presets, it's because there's a DSP chip in there that's helping to record, store, and replay voltage values for the knobs and sliders and switches in the analog signal path. If your analog synthesizer has a sequencer, there's a pretty solid chance that's done on a chip. If your analog synthesizer has a modern modulation matrix, you need a DSP chip for that. If your analog synthesizer has a method for self-calibration, you need a DSP for that. None of these things are done with a DSP chip. They're done with a microcontroller roughly equivalent to an early-80s home computer.
