Of course I know they aren’t samples. My point is that in the context of user-uploadable or user-sampled waveforms, there’s no difference between a fixed waveform from a synth (in the sense that it’s not user uploadable) and a sample that’s fixed. I’m talking about in practice, not in implementation.
You don’t upload new waveforms to a Moog, and the minute differences between one sawtooth cycle to the next are, if anything, more analogous to the sweep of subtle wavetables than anything else, yet some people complain that they can’t change the waves in a wavetable synth yet never think twice about complaining that a Moog has a fixed set of waveshapes.
