Sonic Charge Bitspeek RE - Manual (Page 7)

PITCH OUT
Unlike NOTE OUT , PITCH OUT is bipolar and not quantized to semitones. It pro-
vides an alternative to connecting NOTE OUT if you need more exact pitch track-
ing. However, it requires a slightly more complicated setup, depending on imple-
mentation details of the synth you are connecting. E.g. Thor uses a different range
for CV pitch modulation than SubTractor and Malström.
When PITCH OUT is connected, the NOTE OUT signal will be fixed at middle C.
This is a convenience feature, allowing you to connect both CVs and letting PITCH
OUT be responsible for pitch tracking and NOTE OUT simply provide the base note
for correct tuning.
STEREO : PAN OUT
The analyzed panning position of the source signal. Bipolar, so 0 is center, -1 is full
left and 1 is full right.
STEREO : WIDTH OUT
The analyzed stereo width of the source signal, in other words how much the left
and right input channels correlate. An output of 0 means 100% correlation
(i.e.
monophonic) and an output of 1 means completely uncorrelated.
VOLUME : VOICE OUT
The linear amplitude of the "voiced" part of the source signal. You can use this CV
to control the amplitude of external oscillators fed back into
EXT IN .
VOLUME : NOISE OUT
The linear amplitude of the "voiceless" (noisy) part of the source signal. You can use
this CV to control the amplitude of a noise generator fed back into EXT IN .
Using Bitspeek with Stereo Signals
The Rack Extension version of Bitspeek can be used with stereo signals. It will ana-
lyze the stereo image of the source signal and extract two parameters: panning and
stereo width
(corresponding to the amplitude balance and the correlation of left and
right signals) . Bitspeek will then attempt to mimic the stereo image with the built-in
synthesizer.
The oscillator is only monophonic (but panned) while the noise is stereophonic and
copies the stereo width of the source signal. This solution opens up for some inter-
esting pseudo-reverb effects.
