MURF CV Tempo sync issues
MURF CV Tempo sync issues
Hey I'm trying to tempo sync my murf (the original - not the midi one) to a tr8 drum machine. I have a molten voltage CV sync midi - cv converter. So midi out from the drum machine into the CV sync then into the tap/step input on the murf. It seems so close to syncing but I find that its dragging and drifting. I have the delay only output of a diamond memory lane 2 going into it. Wondering if I'm missing something.. Any assitance much appreciated
Re: MURF CV Tempo sync issues
Slightly bemused as I found a post on another site where someone says Moog advised them to feed the audio click from the metronome in Ableton to the CV rate jack and let the audio signal drive the tempo. Tried using the clap from the tr8 to no avail. It'd be great if the midi to CV converter would sync accurately. Maybe I'm doinf something wrong

page 13 of Manual:
"...and plugging the FS-1 or a gate signal in halfway to this input and the RATE LED turns green."
I hope this helps.

Re: MURF CV Tempo sync issues
The Tempo/Sync jack can do step advance also. If you have a stereo 1/4" Y cable (that splits the stereo out to separate jacks), one signal in will tap the tempo and the other will advance the sequence one step for each gate pulse. The step advance is my favorite feature on the pedal as you can create negative space in between notes instead of always arpeggiating one note after the other. This gives you the power to give the sequences a new rhythm.
My other favorite feature is the ability to control the slider position over MIDI! This is done with the velocity CC which is handy in Ableton clips.
It is a great little pedal and it acts differently on poly synths, monsynths, guitars and probably voices too. I like dragging the notes out really long for breathing drones sounds or really short for plucky sounds.

I plugged stereo jack of Y into TAP/STEP input, then plugged mono jacks to EHX Clockworks outputs, and adjust a different speed rate for each.
And there's no "step advance" effect

Re: MURF CV Tempo sync issues
Sorry for being late. I had the same issue. The Clockworks is fine to clock other gears such as the Mother-32, but for some reasons it doesn't work with my the MF-105M.
I looked at the output of the Clockworks with a cheap oscilloscope and the waveform looks more like a very short decaying impulse than a stable square. I'm not an electrician, but I suppose that's the issue.
So I built a pulse stretcher based on a schematic found in the "Make Analog Synthetizers" book (which is a slight variation of one of the pulse stretcher featured in the "CMOS Mickey Mouse Logic" page on MFOS site). I used a CD40106 for the build, so my module has 3 pulse stretchers. With this device, the waveform of the clock now looks like a pulse and it's much longer and stable than the output of the Clockworks.
Now my MF-105M works fine with the Clockworks.
(For the record, I managed to finish the build just this afternoon.)

So, during this time I bought a second CP-251, and now I can get longer signals from the clockworks through 2xLAG processorssin night wrote:Sorry for being late. I had the same issue.
