KEYBOARDPARTNER HX3 - MIDI Control and Panic Button; General MIDI Control and Routing

22 HX3.5 Mainboard
MIDI Control
HX3.5 accepts MIDI note on/off events (default: channel 1 to upper manual, 2 to lower manual,
channel 3 to bass pedal) as well as various MIDI CCs with selectable compatibility sets. MIDI
dynamics slightly affect key click noise. SysEx data other than its own is always ignored.
Both MIDI jacks act as MIDI inputs with equal priority for connection of two master keyboards or
keyboard and bass pedal. Connecting a third MIDI device requires a MIDI Merge Interface. The
second MIDI jack can be jumpered as MIDI out if required. See HX3.5 Installation Manual for
details.
HX3 functions that are relevant for the organ player may be remote-controlled by MIDI commands.
For details please see HX3 MIDI Implementation. However, some settings are only possible via
the menu system or with the HX3.5 Editor. To recall presets via MIDI use bank select LSB (CC
#32, changeable via menu). To recall voices use MIDI Program Change on the respective
channel.
General
Connect MIDI Out of your MIDI controller or master keyboard to HX3 MIDI input. HX3 cannot
determine the setting of any MIDI controller value until you touch/use it once. As default, all HX3
controllers are OFF. Do not use any controller button or drawbar unless HX3 is ready to accept its
data (Preset/Drawbar main menu appears on the display); it is a good idea to power up HX3 first
and later your MIDI master keyboard or master controller.
HX3.5 supports MIDI over USB through its USB port connected to a USB host, typically a PC.
The USB port and MIDI IN 2 cannot be used at the same time. Please remove any cable from
MIDI IN 2 before using the USB port.
MIDI CC #7 (default, CC number variable) controls master volume. MIDI CC #11 (default, CC
number variable) controls swell pedal/expression if no expression pedal connected to HX3. If you
use your HX3-attached swell pedal, any MIDI expression message will be overwritten. If the
attached swell pedal is not actuated, MIDI expression messages are accepted. Any valid MIDI CC
command will overwrite the HX3's own analog controllers and switches until they are changed on
the HX3 itself.
Note: Some MIDI controllers as well as organ keyboards (like Hammond® XK and SK series)
allow 2nd and 3rd harmonic percussion ON at same time. HX3 implementation regards "2nd ON"
as "Percussion ON" tab in this case.
Panic button
In case of stuck notes just press the upper or lower menu panel button to switch the tone
generator off.
