The Voice Module
Technically the Voice module isn’t in the signal path, so it isn’t located in the Module Select
section of the top panel. But its functions have a signicant impact. Many settings related to the
playability and performance of the patch are found here.

Polyphony settings
It’s possible to stack all 8 voices on a single
note, if you like. There are seven settings here,
but they fall into three main groups..
Poly, Mono, Unison
The Poly setting allows all eight of the
Hydrasynth voices to trigger independently.
When the ribbon is set to Theremin mode,
one voice is reserved for that purpose and the
other seven are available from the keyboard.
Mono and Unison modes are monophonic;
they only allow you to play one note from the
keys or the pads.
Lo, Hi, or both
Both Mono and Unison modes have additional
Lo- and Hi- options. Here’s the dierence:
• Lo (low note priority): The only way to
trigger a new note is to play one below the
held note.
• Hi (high note priority): The only way to
trigger a new note is to play one above the
held note.
• If an option doesn’t say “Lo” or “Hi”, it’s both:
A new note can be triggered by any note
above or below the held note.
Density & Detune
The Density and Detune parameters are only
active when one of the Unison modes is
selected. Density sets the number of voices
that are triggered by the monophonic note.
Detune osets the tuning of each of those
voices equally within the range set by the
Detune value.
Random Phase
Part of what breathes life into the sound of an
analog synth is that its oscillators are always
running; waveforms could be anywhere in
their cycles when they are triggered. It’s the
nature of their circuits; they must be told to
reset. This parameter emulates that behavior
by telling the digital oscillators not to reset
their phase to 0° when they are triggered.
