Introduction (cont.)
Also in either mode, the Partials control works as a combined amplitude and timbre control for the Odd
and Even harmonic outputs. It increases the relative loudness of the harmonics of the current spectrum
as it increases, beginning with silence at counterclockwise, adding lower harmonics at low values,
then through middle and high harmonics, and generating all harmonics at their full amplitude
according to the current spectrum at maximum. The odd and even harmonics are increased alternately
up the control, which can be useful for animation when parallel processing these outputs or using
them in a stereo setup.
Each Side of the Spectraphon has, in addition to Odd and Even harmonic outputs, a Sine and a Sub/CV
output. The Sine wave output always oscillates at the current core frequency as set by Pitch, regardless
of mode, and regardless of the activity at the other outputs. By default, Sub/CV outputs an Envelope
Follower for the Input (in SAM) or a sub-octave waveform (in SAO).
The B side of the Spectraphon can also be set to Follow or Sync. Follow turns the B Pitch control into
a pitch offset that is added or subtracted from the A side's current frequency. In practice, this lets Side A
control the Pitch of Side B, which is useful for dual oscillator patches, tuned FM etc. Sync maintains this
Following behavior, and additionally hard syncs Side B to the current frequency of Side A, turning Side
B's pitch controls into combined pitch/timbre control.
The Pitch, FM, Partials, and Follow/Sync operations, as well as the Sine wave outputs, all work
identically in SAM and SAO. This means that in many respects the Spectraphon can be used as you
would use a dual "complex" oscillator even when the two sides are not in the same mode. It could be
thought of as a complex oscillator that is fed or "driven" by external sound.
The Spectraphon is a digital/analog musical instrument that is not suitable for laboratory use.
