hi,

these are the uses of a cv offset that immediately spring to mind. please correct me if they
can be achieved by other means:

1. a vc offset is also a dc offset. so that any audio signal that distorts will distort
assymetrically.
2. envelopes and lfo's can be swept into and out of negative voltages - so i don't need to
pull out a lead and plug it into a voltage inverter while i'm playing. now i've got my pitch
envelope gliding into the played pitch, instead of the other way around. or having the
played pich at the sustain level, with a too low/too high it at the start of a note.
3. already mentioned: i'd like to have vco's play in thirds. a 138 would do it, but it's
slightly overkill, oder (dieter, is there a hack to increase the range of the tune knob on
the standard vco )

and there must be a dozen other things that i'm forgetting or that other users need that i
don't.

it appears i'm dancing around under the radar here, which implies that silas is quite right
that there's not enough interest. i'm just puzzled that nobody else sees any sense in it.

'cept silas, who's going to vote against it :))
