HARM#/SERIES
This is the primary control for
quickly setting up the various
harmonic relationships of the
channels.
This control makes it easy to
set up rich timbres when using the channels
as oscillators for additive synthesis and to
create complex polyrhythms when using the
channels as cyclical modulation sources.
In Individual Mode, The Harmonic Number
parameter is a frequency multiplier that
sets the channel’s frequency to one of
the frequencies in the harmonic series. A
value of 1 results in the channel’s current
frequency, which could be thought of as the
“fundamental.” Higher numbers set frequency
relationships relative to that fundamental that
follow the classic harmonic series.
If you’re creating polyrhythmic modulations,
this conversion table from harmonic number
to musical note value may be useful. Note
that it assumes Harmonic #1 is a whole note.

A TIP:
Whether for audio or modulation,
start by setting all six channels to the same
frequency. Then set the harmonic number of
each channel to create the desired harmonic
relationships.
In Hex Mode, Harmonic Number has a
different meaning. There it selects the
number of channels playing, from 1 to 6.
Also in Hex Mode, the Option 1 function
lets you select from 15 pre-programmed
harmonic series, instantly assigning each
channel to the appropriate harmonic
number.
In Individual Mode:
Primary:
Sets a channel’s frequency
multiplier from 1 to 16
Option 1:
Sets a channel’s frequency
multiplier from 17 to 32
Option 2:
(Sets a channel’s frequency
multiplier from 17 to 32)
In Hex Mode:
Primary:
Sets the number of channels
playing (from 1 to 6). Channels are silenced
starting with Channel 6 and moving down
until only Channel 1 remains. The Mix output
will auto-scale amplitudes with the number
of channels playing, to keep the mix near the
nominal output level.
Option 1:
Selects a preset harmonic series,
setting the frequency multipliers of all 6
oscillators simultaneously.
Option 2:
(Selects a preset harmonic series,
setting the frequency multipliers of all 6
oscillators simultaneously.).
