Default Anyone have a Schematic for an Alesis QuadraSynth?

It's an easy mistake to make if the connector is in a tough-to-see spot,
as many of them are. I've seen socketed DIP ICs installed with one row
of pins all on the outside of the socket.

Â*Â*Â*Â*Â*Â* But I've never had a keyboard with an after-touch strip.Â* I must
say I don't really like it.


. . . .Â* how the aftertouch affects the voices, in some cases, it
either adds
a vibrato, or makes the note louder, or both.Â* Doesn't seem too useful,
musically, but then again, it would depend of the kind of music you want
to create. I hope there is an easy way to turn the aftertouch off!


I don't know if there's a way to globally turn off aftertouch (you could
disconnect the strip, I suppose), but it's almost certainly a parameter
in the patch that creates the voice. Factory presets are usually created
to show off as many features of the instrument as possible. Get into the
patch editor and you'll probably find how to change what it modulates,
or turn it off in that patch.

Or just don't press the keys so hard.Â*Â*


Yes, I have the manual. Just haven't looked into it in
detail yet. I would imagine I would have to turn the aftertouch
off for each patch.

Now that I've played with it a bit, it seems to be a fairly useful
function for voices like violins, where you sometimes want heavy vibrato
at the end of a note.

But I have another problem: The pitch wheel doesn't work, or only
works intermittently. Could be a bad potentiometer that needs to be
replaced.
