[sdiy] Vibrato range

[Tim Ressel]

That was my thought. Organs use time delays for vibrato and don't do 
pitch bend. I didn't think strings like violins do pitch bend. I know 
they to vibrato. Its called finger vibrato. This is why I wanted to see 
about adding vibrato. I don't think the clock gennies I have in mind 
will do that wide a range. If forced to do pitch bend I'd probably have 
to fall back on the CPLD implementation.

Unfortunately, when playing my old Pro-One (via Encore Expressionist) or Matrix-12, the control stops at one octave and a new MIDI note must be activated when sliding past an octave. It can be a seamless command string, but not always.

Organs typically do not bend pitch, and the synths that allow it really sound goofy in my opinion. I assume that the other common use for a TOG is string synthesis, so I wonder whether it makes sense to support pitch bend. Then again, to contradict myself, strings are fretless instruments, so even the synthetic version should allow continuous pitch - especially when accessed via alternative controllers.
