48 Unison Dave Smith Instruments
Unison
When
unison
is on, the OB-6 functions like a monophonic synthesizer in
that only 1 note can be played at a time. However, that one note can be
powered by as many as six voices, depending on how many you choose
to use. With up to 12 oscillators powering a single note (2 oscillators
per voice x 6 voices), you can create some very dense, speaker-rattling
sounds.
If you want to create an ultra heavy synth bass, try using Unison!
Unison gives you control over not only how many voices to stack,
but also the amount of detuning (with the
detune
knob) between the
oscillators, and what note gets priority if you happen to play more than
one note on the keyboard. (This is called the key assign mode or
note
priority
. See “Key Assign Modes” on page 50 for details.)
When Unison is enabled, the
detune
knob not only detunes the unison
voices but also spreads them out in the stereo field. If an odd number of
voices are stacked, one voice is placed in the center of the stereo field
with the other voices spread right and left. The higher the
detune
setting,
the wider the stereo spread.
