CHORD MODE
When CHORD MODE is acvated, by pressing the CHORD MODE buon, the LED above the buon will light up.
More importantly, when CHORD MODE is acve, oscillator 1 will be split into 8 separate oscillators, each out-
pung the same waveform, but with dierent frequencies. This allows chords to be played when the frequen-
cies are chosen to be at musical intervals, and provides a deep, rich, sound when the frequencies are chosen to
be the same (i.e. a UNISON chord), but with slight variaons in tuning between them.
The amount of detuning between the 8 oscillators can be adjusted by pressing the DETUNE/DECAY buon (as
long as PERC. MODE is not acve). When this is done, the lower line of the LCD display will show the current
detuning value, expressed as a number from 0 to 99. This value can be changed with the rotary encoder. A
larger number means a greater detuning. The detuning is an oset to the oscillator frequencies rather than a
scaling, meaning that the eect for a given detuning is less at higher pitches. So you may want to increase the
detuning amount when playing mainly high notes and lower it when playing mainly low notes. The detuning
parameter can also be modulated by the MOD B input, which is acvated with a second press of the DETUNE/
DECAY buon. When MOD B modulaon is acve the lower row of the LCD display will change to show both
the nominal seng and the oset provided by the MOD B modulaon.
When CHORD MODE is rst acvated, the top line of the LCD display will change to showing the currently
selected chord type. This can be selected using the rotary encoder. There are 64 dierent chord types that can
be chosen. The following table shows the label for each type shown in the LCD display, along with the interval
in semitones assigned to each of the 8 oscillators (0 is the root note). Negave numbers indicate suboctave
intervals (pitches below the root note).
