Schope analyzer and sawtooths

I'm trying out a new audio analyzer called Schope to help figure out some issues I've been having with digital synths. Today I started comparing sawtooth waveforms from an MEK, Radias, MicroKorg, Virus C, Supernova, MS-20, SH-2, and MS-404.

These samples are using a single oscillator, raw unfiltered sawtooth, note = F2, ADSR = 0/0/10/0.

They all look very similar as far as this particular visualization is concerned (frequency domain). The only exception is the Supernova. I'll have to triple check that one.
