Sort of, not really. Let me explain.
If, when you say BPM, you are talking about as generated by Ableton or Logic, or a Drum machine w/Midi; you can certain sync the 105M to it. Important that you pay very very very special attention to the RATE knob as it’s position when in Midi mode dictates whether it will use a 1/8th clock divider or a WH+WH, etc. Have a look at the last msg here: http://www.moogmusic.com/forum/viewtopic.php?f=3&t=7532&p=67159#p67159
(may go without saying but when there is no Midi clock present, the RATE knob controls rate linearly as if it were an Analog LFO).
Unfortunately, the MurF doesn’t have an Analog clock/pulse OUTput so there is no Midi-CV conversion except internally. And since the CP-251 is Analog only, you’ll need a true Midi-CV converter such as they type built into the MP-201 (Moog Multipedal).
Even some of the commercially available Midi-CV product WILL convert note on/off Midi info (to voltage scale and Gate signals) and will even map a CC control (or aftertouch/velocity) to a different CV channel, but not all will convert a MIdi clock into a LFO type of saw or pulse signal that can be used to sync Sample & Hold (for instance) in the CP-251.
As far as the CP-251 is concerned, it is the ONLY clock and happy to drive other pieces of equipment. But [again] with the MultiPedal, you can take a channel output that is sync’ed to Midi Clock, send it into the CP251’s Gate input, leverage the CP’s built in noise and have a sync’ed S+H but then again, the MP can do this all on it’s own.
The CP is a strange beast. In the world of modular Analog, it’s king, combining several functions onto one small box. But once you step into the world of external digital sequencers and Midi, it becomes a fish out of water.
But one more thing… You can certainly take the pulse out of the CP-251 and drive the Midi Murf (or any MurF) via the Tap/Step input using a traditional insert cable. The difference between the Tap and Step function is dictated by which lead on the TRS plug is being leveraged. a typical sustain pedal (mono TS cable) will set the Tap tempo after three ‘clicks’ are tapped in (note that the RATE light flashes Green in this mode). In order to do the Step mode which is also useful in driving from CV LFO (CP-251), you’ll need the tRS portion of the signal, aka Ring. Three ways to do this:
a) Proper Insert cable using Ring
b) Place a conventional mono TS cable about 1/2 in (you’ll see the light change from Red to Green); I’m not a fan of this one
c) Buy the Moog Step adapter which is essentially a female to male converter jack that changes Tip to Ring; I’m not in love with this one either because of the fact that it requires an extra 2" of realestate above your Fooger; if on the floor no problem, but in a rack you won’t always have this space.
d) Wire your own adapter/cable by buying a few parts at Mouser/Digikey/Radio Shack, etc.
Final note is that once you work out the wiring, you can also sync using the “Step” mode with a pulse’ey signal from a drum box set on 4/4 such as a kick or snare drum. But keep the ‘volume’ low and increase slowly until the MurF starts stepping. Don’t blast the signal in as it could cause harm if too much gain is present.
Hope this helps.
So you’re back to tweaking the
