Button 3 Send Patch (action) Sends sys-ex of the current patch via MIDI / USB
Button 4 Send All
Patches
(action) Sends sys-ex of all patches and banks via
MIDI / USB
Knob 5 Overow [1] O, On Connect two Hydrasynths for 16-voice
functionality
Knob 6 Arp TX [1][2] O, On Send Arp note on/o messages via MIDI / USB
Knob 7 Pgm Chg TX O, On Send MIDI Program Change upon patch
selection
Knob 8 Pgm Chg RX O, On Receive MIDI Program Change commands
[1] The Arp TX setting has no eect when Overow is set to On. Overow must be set to O to
transmit the arpeggiator notes.
[2] This also toggles the arpeggiator response to incoming MIDI/USB notes.
Parameter send/receive options
These parameters determine whether the
Hydrasynth will transmit (TX) or receive (RX)
7-bit MIDI CC’s or NRPNs during parameter
changes. This allows for more user-friendly
automation on DAWs that do not support the
MIDI NRPN standard.
The CC numbers for each control are listed in
the MIDI CC Charts (p. 104).
What’s a NRPN?
NRPN stands for Non-Registered Parameter
Number. It’s a way of allowing higher-reso-
lution control data to be sent and received.
Implementation is not standardized, so each
manufacturer uses dierent methods. The
NRPN implementation data for Hydrasynth is
available at www.AshunSoundMachines.com.
Send Patch / All Patches
These actions allow you to transmit the sys-ex
data of a patch or all patches to another
Hydrasynth model. Note that doing that
over MIDI requires two MIDI cables. Ideally
both units would be connected to the same
computer via USB and then patches and banks
could ow freely between the two.
The simplest, most elegant solution is to use
our free Hydrasynth Manager application
(https://www.ashunsoundmachines.com/
downloads). It makes it easy to store your
patches to a computer and share them
between two or more Hydrasynth models.
Overow
Two Hydrasynth models can act like a single
unit using Overow mode. We’ll assume
you’re using two 8-voice Hydrasynths for this
example.
It’s simple: Connect a MIDI cable from the MIDI
Out of one unit (the “master”) to the MIDI In
of the other unit (the “slave”). Next, enable
Overow for both units. Connect the audio
outputs of each unit to your sound system, set
good levels for each, and then:
1. Select a patch on the master: it is sent
via sys-ex and appears on the slave.
2. Play 9 notes on the master: the rst 8
voices come from the master; the ninth
comes from the slave.
Here are some other things to know about
Overow mode:
• The two units will play the same sound. If
you want to layer dierent sounds, disable
Overow mode.
• When a Mono or Unison patch is selected,
the voices on both units are stacked as a
single instrument.
Arp TX
Set this parameter to On if you want
the arpeggiator to transmit note on/o
commands over MIDI / USB. It also toggles the
arpeggiator response to incoming notes. See
The Arpeggiator & MIDI (p. 73) for more info.
Sync information is sent whether Arp TX is On
or O.
