Murf step and Drum triggers

[eric coleridge]

Thanks matt, for some reason, I really like reading and posting on this board; I think it might be a vicarious way experiencing these instruments but without actually buying the equipment. Although, I have owned owned alot of it over the years, and still have some...

a question though. with my .com, inorder to use gate triggers- I need to use the 142 pedal interface http://www.synthesizers.com/q142.html

I didn't know that you need an interface to use gate triggers with a Synth.com system. I thought the Synth.com equipment uses standard gates/v-trig for triggering Envelopes?
A gate signal will often function as an envelope actually. For instance, if you send a gate signal to a VCA or VCF's voltage input, they will open and close almost like they do when sent an envelope voltage. It's all voltages, you know? Even audio signals are voltages. The interface module is there to correct the voltage level, to boost it or attentuate it so that it functions for the use you're intending it for.

Therefore, one other thing about gates/v-trigs is that there isn't a standard voltage level; and different manufacturer's gate inputs respond (or don't respond) to different gate voltages. So, on an Arp it may be 8v to trigger the gate, but on another synth, it may be 5v...

And then, of course, there's S-trigs also... which short the voltage to gate. So, usually, when you insert an S-trig into a gate/v-trig input it gates opposite of what it should...when you hit a key the note turns off.

how is it that the moogerfoogers can read a passive pedal for trigger input [tap input on the murf- i just checked] , if it truly needs a v-input trigger? Is there a way that they accept both? or what?

They accept both.

The thing with the Moogerfoogers is that they are made to be used with CVs or Pedal inputs. They do this with with multi-element(ring, tip, sleeve) jacks. A pedal input needs a voltage source, so the foogers send a CV out on the ring element to power the pedal. Because the pedal is just a potentiometer that attentuates the CV that is sent to it and then sends it back to the Fooger to respond to that attentuation.

But the Foogers also respond to normal CV when you use a normal tip/sleeve jack. The pedal voltage is just shorted out/ignored.

I believe the Synth.com interface also works like this. It has jacks for pedals... or maybe that's another module. [/i]

makes sense. That helps clear up some confusion I was having..

to use certian control pedals and expression pedals on the .coms, you need the Q142 pedal interface to turn the switch trigger to a voltage gate high enough to trigger the various functions. You can also control +5/-5, 0/+5, -5/0 volts- which will help my applications out a lot. Most of my uses for a tap in will go straight to the foogers, so I guess I am covered...

FYI, my setup is a few foogers, the 251 processor- and soon the use of .coms to fill in a couple of holes... I have found getting the 251 is auctually cheaper than getting the same function by individual modules on .com, though they are slightly different... i live vicariously through the Arturia software- and put up with a tad bit of delay... a few hundred bucks to power a few thousand of toys

Yeah, I've never tried the Arturia Modular. I'm sure it can be useful, and alot of fun. But I'm not really a soft-synth enthusiast. I've downloaded some of those Arturia programs and I was amazed at how well it reproduced the static sound of the Mini, for instance. But, I don't think they really capture the sound in motion.. like when you turn a knob... it doesn't really sound or feel the same. I sort of doubt anything that complex could ever really be programmed... but who knows.

I don't have the 251 either, and I've been thinking of picking one up, but I have most of it's functions on my Arp Odyssey. I've also modified this Odyssey for modular capability, so I can send out the noise signal, sample+hold, lfos, env.s, etc. This was my way of getting some modular functions on a budget.
