Hey, this is my first post here. I had trouble registering for a long time. I am having an interesting discussion here (http://acapella.harmony-central.com/forums/showthread.php?t=2145020) regarding controlling a the pitch of a droning bass-line emanating from my MF Rig. Any input would be great!
Long live the Moogerfooger!
Welcome to the forum.
Tellus how you have everything hooked up and what speciffically you are trying to accomplish.

Pretty simple really. I am making a drone bass line. Toward this end I have the Ring Mod Carrier out running to the 107 audio in. The 107 is not synced to the signal so I can vary the pitch of the 107 OSC by hand or with a foot pedal. The 107 audio out goes back through the 102, and then into the 101. I can do exactly what I want to with the pedal by dialing in a “B” note on 107 VCA with the EP-2 fully up. Then use the attentuation knob on the EP-2 to dial in an “E” note with the foot pedal fully depressed. I want my low note to be B and the highest one to by E and by backing off somewhere in the middle of the EP-2’s range I hit D by ear. I can do this fine by itself but when you add in playing a line on the LP or muting tracks on the Machine Drum and what not finding that D sweet spot becomes more of challenge.
So I was looking for a way to automate and accurate get from B to E to D and back to B again autonomously. I found that I can do this by assigning the Machine Drum to alter the Mod Wheel of the XS and send the Mod Wheel Out from the XS into an attenuation channel on the CP-251 and with the proper settings of the Mod Wheel control on the Machine Drum, transition between notes. However, this is undesirable as it limits my use of the XS in certain ways and requires careful setting of the knobs on the Machine Drum, the CP-251 and the 107, essentially more trouble than using the EP-2 and doing it with my foot.
The original purpose of my post was to use the gear I have or get a new piece of gear suggested to me that would allow me to play the foogers without my feet. At this point, I am thinking that there is nothing wrong with my feet but I would love to hear creative suggestions.
Okay this is a long shot
Lets say that instead of using the pedal to switch from the B to the E and then to the D’s sweet spot…
Can you just drone on the B but configure the smoothe sample and hold to switch it for you to the E and back down to the D.
Heres my theory. You are playing a lead line. Then when you have the appropriate moment you can use the cp251 S&H (Smoothe) trigger in (square wave) to sweep the freq upwards from the droning B to the E. It would probably have to be attenuated. Trigger it again and it will go downwards to the D. I can’t answer if the Lag processor will help with this either.
I don’t know how to get it back down to the original B though.
That is just a shot in the dark hehe.

If you have a CP-251 and a second EP-2, you could use the four-input mixer to accomplish this.
Connect EP-2s to inputs 1 and 3 (these are powered jack sockets for expression pedals). Configure the first EP-2 how you did before (B up, E depressed). On the second EP-2, configure in a similar way, but this time, go from B to D. I think you want the offset control at 0 and the mixer/master controls all at 10. Connect the + output to 107 Freq.
When you want to play in B, both pedals should be up. For other notes, depress the appropriate expression pedal, with the other pedal raised.
Of course, you could buy an MP-201 and have easy preset voltages! 
Yeah…when I first saw that 201 I thought “well that is way fancy for my needs, I do not think I would ever need that”. Well…I am a big enough man to admit when I am wrong.
I kept reading this big long list of gear on your signature expecting to see the Mp-201 on there! lol.
Well at first I didn’t think that id want it either, but I remember when this was first announced and some people complained and one insightful member said “Moog has a way of knowing what you need before you do.”
Good catch phrase.
Eric
I think an easy way to get there would be a box with three pots and a switch to select between them. Pot 1 is tuned to B, pot 2 to D, pot 3 to E. Toggle between them for the note that you need.
Bryan
Yes…specifically, a four way toggle. Similar to a guitar toggle, except with one OFF position. You could also have a push button on a 3-position toggle. This would give you more control over which note you wanted to turn off, instead of going over all 3 notes to reach the off position. Great idea, Bryan! 
Nice suggestions, nice suggestions. Thanks. I should definitely look into making a some sort of switching device. That’d be fun. I must say that using the pedal and my foot certainly adds a nice touch…I actually like the slide through the other notes. I can hit “D” now 80% of the time, straight on. It might save me $500…
Maybe…once you buy one Moog product, you usually want the rest of them. There will be a time when I buy a Multipedal…just not in the near future. After I buy my .com system. Also, if you’re into vintage videogames, the multipedal could be used as a paddle controller with a homemade cable on the MIDI out. You could literally play Super Breakout while playing your synths!
I think the Frostwave Fat Controller could do it. But it’s apparently out of production and wasn’t cheap when it was.
