what can i do with carrier out on ing mod?

Duke Foog · Post by **Duke Foog** » Fri Sep 16, 2005 3:01 pm

Just got the low pass filter and am loving it with my murf and ring mod. Just figured out how to patch lfo out or envelope out to control various knobs on these pedals but am still a bit hazy about the carrier out. any good ideas on what this does in the way of cv. it's an audio and cv signal right?

lfo oscillates whatever you plug it into.

envelope gives dynamic control over whatever its plugged into.

what about this carrier out. since it's a frequency how will it affect say the rate of the murf, or cutoff of low pass filter?

still a bit confused

by the way thanx alot for that octave suggestion with the ring mod by splitting a signal and having it go into both inputs of the ring mod.

Well, you could do some things:

-The Carrier out can be used as a modulating source much like an LFO but it generates much faster rates, creating Ring Mod-ish modulation. Remember that an LFO its also a frequency (Low range) much like the Oscilator on the MF 102 (Higher Range)...The higher the frequency range the faster rates of modulation you'll get.

- You can use the CV out as an Audio source and create some crazy noises, you can use this signal through a delay add an LFO and create some spacey sounds.

- You can also use a MIDI to CV adapter send a CV to the Freq. input and then use the Oscillator (Carrier out) and you will have some kind of synth to create crazy noises.

-If you have the MF103 Phaser you could modulate the Sweep in to create some interesting modulation.

I hope this helps.

Regards.....

thanks i'll try that out

btw, the lfo in the 102 is a triangle and not a sine as stated in the manual and printed on the unit

is this really true? i would think that it would be weird if this were the case...

This is true. Sine and triangle waves are very similar, so similar that Moog decided to label it sine. The LFO on the 103 is triangle also, I believe.

The Voyager does not have a true sine wave output from any of the oscillators (expect the LFO) becase you can easily turn a triangle wave into a sine by running it through a low pass filter.

Send a S+H LFO to the Freq. In on the RM. Use the carrier as audio. Process as desired.

actually, the manual claims BOTH in different sentences...in places it refers to it as a "triangular" wave...then in other places it talks about the "'square-sine' waveform swtich"...but then it goes to describe the switch: "...selects either the square waveform or the sine-<b>like</b> waveform that the LFO produces." so yeah, i guess they figured it didn't make much difference which they described it as...save for anal nerds on a message board...

i tried using the carrier out as an audio source and had neat results, especially using the delay and modulating the delay time.

i haven't really had any luck using it as a cv output though. even if i did it seems kind of pointless because unless the lfo on the ring mod or some external source is modulating the frequency it won't actually do anything. at that point it makes more sense just to use the lfo itself rather than the carrier out.

i might be missing something though...

The carrier is an oscillator just like the LFO is an oscillator. The LFO has either square wave or sine (actually triangle) wave but only does low frequencies (0.1 to 25 Hz). The carrier is a sine wave that does low frequencies to higher frequencies (0.6 to 4000 Hz). You can use the carrier anywhere you would use the LFO, as a control source or an audio source.

but doesn't the carrier frequency stay at the same frequency unless the lfo on the ring mod or some other control source is modulating it? and if it outputs a constant signal/frequency then it won't actually be continuously changing the value of another setting (like the time on the delay)? so you can use it as a control source, but it doesn't seem to be that useful (like the lfo is).

maybe i am understanding it completely wrong though or just not seeing how to use it, i'm still learning...

Nope, just twist the frequency knob! Try it right now. Hook the Carrier output up to a speaker and turn the knob marked FREQUENCY. The LO and HI switch changes the frequency range ((0.6 to 80 Hz) or (30 to 4000 Hz)).

The LFO and the Carrier are fundamentally the same thing. The Carrier simply operates over a greater frequency range than the LFO. It will make sense with time, just keep at it!

i went and messed around and think i got it now! or at least better than i did. i knew that you could change the frequency with the knob, i just thought that the frequency only changed if you turned the knob or used its cv jack. i didn't get that it constantly oscillated like the lfo until i specifically listened for that. i also think that i tried to use it in the "hi" frequency setting when the "low" seems to work better as a control source

thanks!

I depends on what you are modulating. You can get some real cool stuff if you use a high frequency to modulate something like the cutoff of the MF-101 or the rate on the MF-103.

thanks for all the tips oysterrock, i appreciate it.

after some more fiddling around today i figured out how to use the carrier out as a control source somewhat and got some neat results.
