Am I missing something or is there an actual advantage to those
distorted sine waves on all Doepfer oscillators They don't sound or
look much like sine waves at all. Is there a user advantage or is this
just a trade-off design for cutting costs (i.e. lame diode tri-to-sine
converters)

With such high distortion, Doepfer sine waves don't make useful
additive or FM sources, and not enough harmonic content as useful
subtractive sources. The distorted shape makes noticeable unnatural
sounding LFO modulations. I find I never use them and wish for higher-
quality pure sine waves.

Sadly from the scope shots, I noticed even the 111-2 still maintains
these low-quality sine waves. What am I missing
