I'd say a true hardware synth is something that
uses multiple variable
rate DAC and other semi-analog or analog stuff that you can't
replicate purely in the digital domain. The SID chip falls in that
category, for example. (Digital oscillators, analog mixer, analog
resonant filter, IIRC.) Didn't some early Ensoniq synths use a
similar approach? (Per-voice DACs, that is.)
Nope. In the DOC-based synths there was a single DAC for all control
voltages and the DOC built-in DAC for all audio channels. Anything with
a DOC chip (Mirage, ESQ and SQ range, and their sampled electric piano)
had real CEM analogue filters.
It depends on
the software involved. Great though Novation stuff
is, it aliases terribly (for instance). Nice filters though.
Ouch. The first thing I look for when hacking my own oscillators is
distortion when playing pure sine waves all over the frequency range.
If that sounds crap, everything will sound... well, at least not as
clean as it should. If it's not too bad, it might be ok for some
sorts of sounds...
