OH, OH, this sounds great. I guess the main thing I can thing to use a VC
Lag would be portamento. Are their others? Tell me more oh modular gods.
My comments (since you asked):
You asked for a vote on the light, if ON when bypassed, I vote RED.
Although the two color thing would be REALLY cool with green = active and
red = bypassed. <grin> Would it be possible for the bypass to function
two ways - one as you described but also going into bypass or active when a
certain DC voltage is exceed when applied to the tip connection of the same
jack ?
I really like the idea that you can vary from linear to exponential for use
as portamento. This will allow duplication of some of the non-typical expo
glides of some of the classics.
Seems to me like the "shape" could actually be varied to lots of other
extremes by attaching an EG output to one of the voltage inputs. If I am
thinking right, using the negative output of the a 800 seems like you could
even get reverse-expo effects.
It also seems to me that it would be useful to be able to control "initial
controls" even when using CV. Help me if I am thinking wrong, but it
looks like you could by putting the CV into the "UP & DOWN" input and using
the separate "UP" and "DOWN" pots for initial control.
Someone PLEASE explain to me how this module would be used with audio as an
input. What are other uses other than portamento & glide effects?
Too cool Paul ! A "3 out of 10." Looks like I tell my wife her module is
coming soon.
Now, when should I tell her to expect it? And, the one million dollar
question...... will it be soon enough so I can give my wife MOTM for
Christmas? Now, THAT would be a dream gig !! <grin>
Concerning 1U x 19" phaser.... GIMME !! MOTM branded or not, it's going
in my rack. I have really been wanting a good phaser and saddened that
such a great looking MF product is in that "pedal-like" format.

P.S. Just for s∗∗ts and grins (as they say), what were the other two
candidates for the mystery module?
