integrate the lp to a modular system

i m having a lp 2 and ist a lil beast, im also intrestet in a doepfer a100 modular synth...how is the integration via CV with the phatty...
are there any user with expirience out there?
with pitch CV on the phatty can i play notes on the a100?
i m not into the use of CV does it work bidirectional? or just in one way like midi?

CV is unidirectional. An in to an out is one direction, an out to an in is another direction. Multiple ins can be patched from multiple outs simultaneously. As long as the Doepfer doesn't exceed 5 volts, life should be good as Moog gear isn't made to handle more than 5 volts per jack.

Well thats true in a sence and its also untrue.

Some cables are capable of sending and receiving CVs. Like for instance, the MicroMoog has modulation routing that simeltaneously sends and receives the signals. These may not necessarily be CV's though.

I don't think im qualified to say if CV's are strictly unidirectional or not.

LP pitch cv jack is for input only, one-way. For the A-100 I'd suggest getting the midi-cv converter module, then all you'd have to do is plug the LP's midi out into that and you're good to go. That's what I'm doing now to control my Future Retro XS, which in turn is controlling a MF-107. Works great!

Actually, I thought about this statement, and after thinking it over, realized the second statement makes no sense.

An out ALWAYS sends voltage to an in. Silly me!

I have a FutureRetro XS as well, but typically use it to lay down lines separate from the the LP. I would really love to hear what you do sounds like. It sounds kick ass. I am assuming that you are controlling the OSC of the MF-107 via the CV OUT on the XS.

Any of the tracks on your my space feature this specifically?

okay good to know but you could send maybe notes over midi and having on the a100 an extra osc thats goes to the audio input of lp and some extra lfos that modulate over lps cv inputs...

just remember the LP doesn't have an audio input volume control, so make sure to run that osc through the a100's mixer first and then into the audio input. raw oscs will completely dominate over the LP oscs if not brought down.

Wow, plenty of Future Retro XS on Little Phatty lovin'. I have that setup, too... and just ordered the Orb sequencer; it should be here Monday! w00t

The only thing that turned me off about the Orb is the output is up to 12 volts, and is therefore not compatible with my LP...unless I MIDI'd it. But then I could save money by buying a MIDI sequencer, and am not fond of MIDI anyway. Someday I'll jump on the FR bandwagon, but for now it's just me and my Moog.

I have had not problem with the XS going directly into the Moogerfoogers. I am not sure I would put it into the LP, but I generally attenuate the signal now through the CP-251

Voltor07 · Post by **Voltor07** » Thu Mar 19, 2009 10:43 pm

Yes...an attenuator makes sense. Now that that problem has been solved, where do I put the thing? It'll be awhile before I get some Future Retro stuff, anyway. I have no idea why I didn't think to use an attenuator. Better yet, an attenuator with a built in analog voltmeter. Back to the workshop I go!

I have a couple newer tracks that feature the XS and Phatty+MF-107 together, will try and put something up soon, thanks for hitting up the site!

AGHGGHG I WANT ONE SO BAD!!!

Sold my Revolution a while ago to fund the XS, I'm missing being able to program stuff without clicking a mouse pad. Have fun w/ the new toy, I just bought a Diamond Memory Lane 2, so no Orb for a while yet.

Oh, the XS. I still want one, but that damn free cp 251 offer made me go and get a little phatty instead! Oopsy! LOL!

I'm going to have the best synth rig one of these days...Moog, FR, AND synth.com! You just wait. Oh, yeah, steampunk electric Yamaha drum set too.
