Understanding The Modules; Module Groups; Oscillator Group; Mixer Module - Ashun Sound Machines HYDRASYNTH Owner's Manual

The orange-lettered Access buttons select particular modules for editing, and can also be used
to create new mod routes. They are arranged in the order of signal flow, from left to right: [Osc]
> [Mixer] > [Filter] > [Amp] > [FX]. The front panel graphics indicate this, and also show the
interactions and independence of the modules.
There are two exceptions to the signal flow rule:
• The Voice module, located below the Exit button. It provides features such as the Unison
modes and Scale.
• The Ribbon module (keyboard only), which defines the behavior of this performance control.

Module Groups

We'll only touch briefly on the modules here; most have their own chapters. Their purpose here
is to introduce operations that can be performed by any two modules from any module group.

Oscillator group

The Oscillator group includes Oscillators 1-3,
the four Mutant modules, and the Ring-Noise
module. After the waveforms are generated
by Oscillators 1 and 2 they pass through their
respective Mutant modules before heading to
the Mixer module, where they are joined by
the outputs of Oscillator 3 and the Ring-Noise
module.
The modules that are in the Oscillator group
are described in The Oscillator Group

Mixer module

This module has some simple but important
functions, including the relative levels and
panning of the oscillators, how they are routed
through the filters, and whether the filters are
in a series or parallel configuration. Full details
are in The Mixer Module

Filter group

Filter 1 and Filter 2 are similar in name and
function but their features are very different.
• Filter 1 has 11 different filter models,
including Low- / High- / Band Pass and
vocal formant options.
• Filter 2 is a multi-mode filter that can
"morph" between its Low Pass, Band Pass,
and High Pass states.
The filters can be placed in parallel or series.

Understanding the Modules

Envelope group

All five Envelopes have identical parameters.
Dotted lines connect ENV 1 to the Filter group
and ENV 2 to the Amp module, which means
they have pre-wired connections that show
up as parameters in those modules. But all
Envelopes can be used as modulation sources
for any destination, and Envelopes 3-5 can be
used as additional modulation sources for the
Filters and the Amp module.
Note that Envelope 2 does not show up by
name inside the Amp module, but its input
level is controlled by the AmpLevel parameter.

LFO group

All five LFOs have identical parameters. Dotted
lines connect LFO 1 to the Filter group and
LFO 2 to the Amp module, which means
they have pre-wired connections that show
up as parameters in those modules. But all
LFOs can be used as modulation sources for
any destination, and LFOs 3-5 can be used as
additional modulation sources for the Filters
and the Amp module.
