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 different methods. The
NRPN implementation data for Hydrasynth is
available at AshunSoundMachines.com.

Send Patch / All Patches

These actions allow you to transmit the sys-ex
data of a patch or all patches to any sys-ex
librarian.
You can also send those items to another
Hydrasynth. 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
flow freely between the two.
Overflow
Two Hydrasynths can act like a single unit
using Overflow mode. 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 Overflow for both units.
Connect the audio outputs of each unit to
your sound system, set good levels for each,
and then:
Settings Description
On, Off See website for implementation chart
On, Off See website for implementation chart
(action) Sends sys-ex of the current patch via MIDI / USB
Sends sys-ex of all patches and banks via
MIDI / USB
Off, On Connect two Hydrasynths for 16-voice
functionality
On, Off Send Arp note on/off messages via MIDI / USB
On, Off Send MIDI Program Change upon patch
selection
On, Off Receive MIDI Program Change commands
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 first 8
voices come from the master; the ninth
comes from the slave.
Here are some other things to know about
Overflow mode:
• The two units will play the same sound. If
you want to layer different sounds, disable
Overflow 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 / note off
commands over MIDI or USB. Sync information
will be sent whether Arp TX is On or Off.

Pgm Chg TX / RX

These parameters determine whether the
Hydrasynth will transmit (TX) or receive (RX)
MIDI program change commands.
