- You'll get the classic vocoder-type sound by using the keyboard (maybe a
- strings sound) into the "instrument" input on the vocoder and singing into
- a mike plugged into the "mike" input (remember the weird robot-like backing
- vocals in the Cars' "Dangerous Type" and the "Ahhhhhhhhhhhs" in the background
- vocals of the 10cc tune "I'm not in love" ???). A vocoder (I'm assuming you
- have the old standard Roland Vocoder?) to me doesn't sound much like a chorus or
- flanger but uses very similar technology to acheive it's effect. It feeds the
- "instrument" input through a bucket-brigade analog delay line just like a
- old fashioned analog chorus/flanger and the "mike/voice" input is used to
- generate an envelope with which to modulate the "instrument" signal. I can't
- remember if the delay time and/or regeneration of the bucket-brigade device
- are modulated by any part of the incoming signls or if they are fixed or
- adjustable from the front panel. By feeding in a slow sweeping long sustaining
- strings sound from the keyboard into the "instrument" input and feeding your
- guitar into the "mike" input, you might get some flangelike sounds. Experiment.
