To use the output of voyager into the audio input distortion trick, should I use a ‘Y’ adapter on one of the outputs to maintain the stereo signal or should I just give up the stereo and go mono on my voyager? Seems that If I don’t, Voyager would detect both outputs being used resulting in only one side making it out to my mixer.
I don’t. I use the mixer feedback loop instead, and with regard to pedals, I find you can get crunch tones out of most synths that give you three or more primary sources with which to play, without any external devices. Along with Vger, these synths include EML-101, 2600, Minimoog D (preferably modded w/sync), Korg MonoPoly (in mono mode), Cwejman S1, SE-1X, M5, homebrew modulars, etc..
Crunch tones can be generated using oscillator tunings, in conjunction with
sync, audio-rate mod, and a few other tricks.
My secondary method of this is mixer saturation, which depends more on the particular type of the synth you’re using, but the Memorymoog, and
newer pieces like the S1 have mixer sections that will do this easily.
With reference to the Vger, it can be a valuable learning experience to use the synth’s own patch resources (feature set) to dial in the effect you’re going for, and use external pedals only on an as-needed basis.
This is my own method of working with some gear; use effects only for polish, or icing-on-the-cake, and depend on the synth for the substance of the patch. This doesn’t necessarily work for everyone, and where it doesn’t the insert loop provides an additional point at which to try many of the crunch boxes listed on this and other fora.
