HX3.5 Mainboard

HX3.5 is a tonewheel emulator with all the features of a classic electromagnetic organ. It is

controllable via MIDI with selectable CC sets for various keyboards. The CC sets are editable.

Alternatively, the module can be controlled via Fatar or other keyboards as well as drawbars,

switches and buttons. HX3.5 offers unlimited polyphony, 100 presets, 3 x 15 drawbar presets and

CaM rotor simulation with rotary speaker, scanner vibrato and amp 122. General MIDI sounds

such as piano and strings are also available.

As an option (extended license required), the HX3 RealOrgan engine is capable of emulating all

electromagnetic organs including the famous H100, combo organs, concert organs of the 70s and

80s like Böhm Orchester and Wersi Helios. This implies up to 15 harmonics, up to 12 drawbars

per manual with individual mixtures, including phasing rotor (WersiVoice). An ADSR envelope is

available on all drawbars, also H100 percussion and "Harp Sustain". Various tone generator

waveforms are selectable, for "cheesy" combo organs as well as fully fledged concert organs.

Features

Compact organ emulator circuit board, 200 x 100 mm

Authentic reproduction of the tone generator. Key contacts, percussion, rotary effect, scanner

vibrato and TubeAmp realized using physical modeling in pure hardware.

Extremely low internal latency of 50 microseconds Key-to-Audio. However, MIDI transmission

delay is about 1 ms per note played.

Natural key click due to 9 (B3 mode) or 12 (H100 mode) contacts closing in succession

Authentic ‘CaM Rotor’ simulation with 122 tube amp

General MIDI (GM) Synth, 54x polyphonic

Tunable in range of A = 433 through 447 Hz

Effects DSP providing 3 reverb levels

Dual MIDI IN for two keyboards or bass pedal

LCD display and menu system available

Swell (expression) pedal and footswitch jacks

USB for MIDI over USB, firmware updates, parameter editing

Default MIDI setting: channels 1/2/3 for upper/lower/bass, MIDI CC NI B4.

DC input 9 to 12V, 500 mA min., 5.5/2.1 mm plug, plus on center or through connector PL12,

alternatively 5V through connector PL11.

HX3 Apps and Tools

The Menu Panel chapter describes how you can fully control the HX3 system via a menu panel

connected to the HX3.5 mainboard. However, there are other, more comfortable options: Use the

Panel in the HX3.5 Manager for operation via PC or notebook. Use TouchOSC for operation via

tablet or smartphone.

HX3.5 Manager

The HX3.5 Manager supports the use of your HX3 device

with a variety of functions:

The Panel contains switches and drawbars for your HX3

device. In the panel window you can adjust sounds and

effects, create, name and save presets. When the panel is

open, you can recall presets live using the function keys on

your PC keyboard.

The Preset Mover makes it easy to manage presets. It lets

you try out, move, and rename presets. You can transfer

presets from a file to the HX3 device or save them to a file.

The Editor lets you set up the HX3.5 for all conceivable

hardware configurations, gives you access to all available

parameters, and lets you fine-tune sounds and effects.

With the CC Set Editor you can edit the MIDI CC Sets of

the HX3, create CC Sets or load them from a file from your

PC. This allows you to get the most out of your keyboard

controller, even if none of the included CC Sets fit right

away.

The Updater updates the operating software of your HX3

device completely in an automatic process or individual

selected parts. Use the Updater also to activate an

Extended License or to change the username.

TouchOSC for HX3.5

Control your HX3 device via tablet or smartphone with the TouchOSC app from Hexler, which you

can get for a few euros in the Apple App Store or Google Play. For wireless connection of iOS or

Android mobile devices we offer a WLAN interface. iOS devices can also communicate with

TouchOSC via MIDI over USB.

6 HX3.5 Mainboard

Jack Connections

HX3.5 mainboard jack connections from left to right:

SWELL PEDAL ¼” stereo jack: Expression pedal input is compatible with Yamaha FC-7 and

similar expression pedals. Plug connection: Sleeve = ground / potentiometer start, ring =

potentiometer tap, tip = potentiometer end. Expression may also be remote-controlled by MIDI

control change.

FOOT SWITCH ¼” stereo jack: Single or double footswitch controls simulated rotary speed:

SLOW/FAST on plug tip, RUN/STOP on plug ring. Please use latching foot switches;

momentary (button type) switches are not supported. If single footswitch used, Rotary is

always on RUN (no plug ring, input grounded by plug sleeve).

USB USB B-type connector for MIDI over USB, updates, parameter editing. USB port and

MIDI IN/OUT cannot be used at the same time.

MIDI IN/OUT Factory default secondary MIDI input for additional lower manual, bass pedal or

MIDI controller. Optionally jumpered to supply +5V/200ma to our Drawbar Controller (phantom

voltage) or pedal scan board Bass25. May be changed to act as MIDI OUT by internal jumper

swap. See HX3.5 Installation Manual for details.

MIDI IN Primary input from MIDI keyboard.

DC IN: Use stabilized DC wall wart 9 to 12V with at least 500mA current output, inner/outer

plug diameter 2.1/5.5 mm on DC input jack. Polarity: positive voltage on inner tip.

AUDIO1/AUDIO2: Main audio stereo output. Output level is approx. 300 mV at full swell.

For control of parameter settings, we recommend the use of our MenuPanel. Installing the menu

panel and other peripherals is described in the HX3.5 Installation Manual. The menu system for a

standard organ configuration, using drawbars, our Panel16 switch button board, and keybeds

connected through our key scanning boards is described below.

Please note: Factory default programming is the HX3 MIDI Expander firmware. You may set up

the HX3.5 mainboard conveniently for your organ configuration by means of the HX3.5 Editor. See

the HX3.5 Manager User Manual for details. All software, documentation, and manuals are

available online on keyboardpartner.com in section Support & Download.

Swell Pedal/Volume Control

Output level of all output channels is controlled by Master Volume setting in menu or MIDI CC #7

“Volume”, whichever occurs last.

Organ's swell pedal position is controlled by an expression pedal or MIDI CC #11 “Expression”,

whichever occurs last. HX3 resembles a loudness curve similar to the swell pedal of a classic

tonewheel organ, so expression volume will not reach zero. We recommend connecting an

expression pedal Yamaha FC-7 or similar (1/4" jack, 10k to 47k total resistance) directly to the

HX3 module. By using an expression pedal rather than MIDI sweller control will be faster and

more precise.

MIDI CC #11 and #7 may be changed by menu to other valid MIDI CC numbers.

8 HX3.5 Mainboard

Controls

Up to 64 pushbuttons or switches and up to 88 potentiometers (also drawbars) can be connected

to the HX3.5 mainboard.

Panel16

In the default configuration, a Panel16 is required. Default assignment of the Panel16 (parameter

1504 in the editor = 0, 5108 = 60, 5109 = 61, 5110 = 62, 5111 = 63):

If a rotary switch is used to switch between V1...V3/C1...C3 (parameter 1497 = 0), the four buttons

at the bottom left can be used to quickly select presets (parameter 1504 = 2):

The preset buttons are binary coded, i.e. preset 1 toggles between 0 and 1, preset 2 between 0

and 2, preset 3 between 0 and 4, preset 4 between 0 and 8. You can press several buttons

simultaneously and thus select values from 0 to 15.

The buttons of the Panel16 can be assigned differently in the editor as desired. Preset buttons can

optionally be used for drawbar presets (like the inverse buttons of a classic Hammond console).

See section 'Setting up the Hardware Configuration' in the HX3.5 Manager manual.

Preset12-2/Preset16

The drawbar presets (Voices) can be switched independently from the common presets and are

also selectable via the Menu Panel. Register boards Preset12-2 or Preset16 are required for fast

switching by keystroke.

Use the Preset12-2 board in conjunction with inverse preset keys on the keyboard. This allows

you to recall 2 x 12 drawbar presets.

The Preset16 board has two rows of 8 LED buttons each. A second Preset16 board can be added.

All details about the configuration in the HX3.5 Installation Manual.

To save a drawbar setting as a voice, press and hold the target button for two seconds.

If a common preset is selected and thus overwrites the current voice, the LED of the respective

button flashes. Press the button if the voice preset is to take effect again instead of the drawbar

preset stored in the common preset.

HX3.5 Mainboard 9

Menu Panel

On power on, the Preset/Drawbar Menu is present. Pressing the

rotary knob twice briefly will let you return to the home position from

any other menu position.

Turn the rotary knob to scroll through the menu. A hatched arrow indicates the menu position.

Press the rotary knob once to edit a parameter value. A white arrow indicates the selected

entry that may be altered. Turn the rotary knob to change that value. Press the rotary know once

again to continue scrolling through the menu.

In the preset/drawbar menu the rotary knob selects the Presets 0 …99. Presets consist of

drawbar settings and optionally tab switch settings (percussion, vibrato etc., including rotary

Run/Fast/Slow), volume and 122 tube amp gain as well as all other effects.

Scroll downwards (= turn the rotary knob clockwise) to the drawbar

presets (Voices) for Upper manual, Lower manual, and Pedal. The

top display line shows the drawbar positions as numbers from 0 –8.

Scroll down one more step to get to the Master Volume setting. Master Volume adjusts the

overall volume for all outputs. Higher values are recommended for the best signal to noise ratio.

Scroll down to the TubeAmp Gain setting. TubeAmp Gain sets the

internal tube amp simulation.

A star appears at the bottom right of the display, if a parameter value has been changed and

differs from the stored preset. To store values as Preset, keep the encoder knob pressed until the

prompt “Save to Preset #XX” appears on the display. (“XX” representing the current preset

number). Alter the number as desired and press the knob once again to have all settings stored.

Parameter values tagged by the letter Care part of a single preset. Values tagged by Dapply to

all presets and are stored as defaults. The assignment can be changed in the editor of the HX3.5

manager with parameter #1498 or in the panel.

Values tagged by U, L, or Pare part of the current voice for upper, lower, or pedal. These are

saved as Voice (Drawbar settings only) if you save them while one of these markers is displayed.

10 HX3.5 Mainboard

Menu Overview

The HX3 menu is arranged in function groups and has two levels: The main menu shown in

bold contains the parameters that are frequently used. In the submenu of the respective function

group, shown in blue, you will find parameters that are used less frequently.

Press the lower button to switch from a main menu to a submenu. An "S" symbol then appears at

the bottom right of the display. Press the upper button to return to the main menu.

The menus are arranged in a ring. The last menu item in the list is therefore followed by the first

again when you scroll down further, and the same applies vice versa.

Some menu items are only available with the Extended License. These are shown in italics in the

following overview. It also depends on which organ model is selected (default: B3). In the

overview, a light blue Hmarks menu items that only appear in H100 mode, and a red E marks

menu items that are available in EnvelopeGen (EG) mode. Depending on the device type, some

menu items are omitted or replaced by physical controls.

As of firmware version 5.637, the menu is significantly shorter than in previous versions. Rarely

used parameters have been removed from the menu to improve clarity, but are still adjustable with

TouchOSC, with the Panel or with the Editor of the HX3.5 Manager. Please use this method for

the manifold settings in EG mode.

The editor can be used to remove unwanted menu items from the menu.

Presets

HX3 Preset: Selection of Common Presets 00 ... 99.

Common Presets include Drawbar settings and optionally Tab Switch settings (Percussion,

Vibrato etc.), Rotary Run/Fast/Slow, Master Volume, TubeAmpGain, and other effect settings. In

the HX3.5 Manager panel you can select which parameters are saved in presets.

Preset 0 takes over the live settings of drawbars and switches, if they exist. All other settings in

Preset 0 are stored as default values and take effect when the HX3 device is switched on or

Preset 0 is selected again.

LED Dimmer: Brightness of the LEDs on connected boards and on the menu panel of the HX3

MIDI Expander (from mid 2020).

SD File Exec: Selection of a script file on the SD card when the SD card adapter is connected.

WiFi Init Def: Reset WLAN interface to factory default.

Preset Init: Sets the live preset 0 to a basic B3 organ sound.
