What's an LFO?

LFO is an abbreviation for Low Frequency Oscillator. LFOs are the cause of familiar effects like
vibrato and tremolo, but they can be used in very complex ways (as the presets will attest).
Hydrasynth has 5 LFOs that can modulate any available parameter through the Mod Matrix. All
5 have identical parameters, so every description applies equally to all.

LFO features

Hydrasynth LFOs might be more flexible than
any you have encountered. Here are some
highlights:
• Delayed onset through the Delay and
Fade-in parameters
• Adjustable phase: start the modulation
from any point in the LFO waveform
• Synchronized or unsynchronized modes
• A wide range of rates, from super slow to
audio
The Vibrato feature is a sixth LFO dedicated to the mod wheel. It is not available as a
source or destination in the Mod Matrix. For details, see the
the Voice module chapter.

LFOs 1 and 2

Hydrasynth has pre-wired connections linking LFO 1 to the Filters and LFO 2 to the Amp
module. More LFOs can be routed to these destinations as needed through the
(p. 73).

• Independent LFO per voice
• LFOs can modulate themselves, each other,
and/or anything else
• An LFO can be triggered a single time or
loop indefinitely
• Design your own LFO with the Step LFO
features

Description
Selects LFO waveform. "Step"
is user-defined
Sets duration of LFO cycle
Toggles LFO rate from Hz to
synchronized time divisions
Poly: independent LFO per
voice
Single: LFO affects all voices;
each new note retriggers
LFO
Off: LFO runs freely
