Vocoding and other spectral transfers
Using two SMR's, you can create spectral transfer effects. One type of spectral transfer is known as Vocoding, which is
classically used with human speech and a sawtooth oscillator.
Patch a human speech audio signal into the first SMR's odds IN. Use a vocal sample, or a microphone with an audio
input module. You are not limited to just using human speech, but it's a great way to start playing with this technique.
Patch the carrier signal into the second SMR's odds IN. Use a sawtooth VCO, or perhaps an FM'ed VCO. You also could
use another sample or a complex sound from another patch.
Patch the second SMR's evens OUT to your mixer so you can listen. You also may wish to patch the first SMR's evens
OUT to the mixer for monitoring the modulating signal.
Flip Post | Pre to Post on the first SMR
Patch all six Env Outs jacks on the first SMR to the six Level CV jacks on the second SMR. If this is your first time, keep
them in the same order (1->1, 2->2...)
Play with the rotation, spread, scale and bank of both SMRs. You might want to start in the blue bank (graphic EQ) and
with the channels positioned as shown in the diagrams above.
Play with the RES (Q) of both SMRs
To fine-tune the patch, follow the technique outlined in the Re-mix patches, setting the note, scale, bank, and resonance of
each channel on both SMRs.
Usage
Channels: Six resonant filters
The core of the SMR is six resonant band-pass filters. The six channels take their inputs from the audio IN jacks, and their
outputs are mixed together using the sliders and Level CV jacks. The mix is then fed to the audio OUT jacks. The audio IN
jacks are normalized to a digital noise source, so no input is necessary.
Channel color
Each channel is given a color. By default, channel 1 is blue, channel 2 is cyan, channel 3 is green, channel 4 is pearl, channel
5 is orange, and channel 6 is rose. The colors can be changed by editing the Color Scheme (see Advanced Features). The
color is shown on the light ring and also on the Env Out lights. The easiest way to see the color of a channel is to glance at its
Env Out light's color. Another way is to slide its slider up and down and see which light on the light ring is going dim and bright
(you must be in Rotate mode).
Digital noise source
A digital noise source is normalized to the odds IN jack. With nothing plugged into the odds IN jack, the SMR will
filer/resonate this digital noise source. The noise source repeats its pattern, and the frequency content fluctuates.
Stereo/mono operation
For mono operation, patch into the IN and OUT jacks circled in black (odds IN, evens OUT).
