MIDI

UHT - MIDI Encoders convert UHT - KEYBOARD signals into MIDI signals. Each manual is connected by a 20pol. flat ribbon cable. Commercially available MIDI cables must be used for the MIDI connections. They can be purchased in different lengths.

MIDIO 1 LC

- for 1 manual or pedalboard
- 1 x MIDI OUT
- dynamic (velocity) mode
- single contact mode (NOTE ON/OFF)
- upper or lower contact selectable
- MIDI channel is fixed = channel 1
MIDIO 4

MIDIO 4 LC
- small version of the MIDIO 4
- for up to 4 manuals and/or pedalboard
- 1 x MIDI OUT
- dynamic (velocity) mode
- single contact mode (NOTE ON/OFF)
- upper or lower contact selectable
- MIDI channels are fixed = 1, 2, 3 and 4
MIDI - MERGER 2

- 1 x MIDI OUT
- 5V power supply is required
MIDI - MERGER 4
- 4 x MIDI IN
- 1 x MIDI OUT
- 5V power supply is required

HW2 - EXTENSION

The HW2 Extension is developed to be used in combination with the Software „HAUPTWERK“ to connect (unlighted) pistons and swell pedals. As the name implies it is an extension. HW2 does not have its own MIDI Encoder on board, so it will not work without MIDIO4.

UHT - HW2-Extension

With the HW2 Extension you can connect a 5th manual and a pedalboard, both velocity sensitive. With the small DIP switches the velocity mode can be switched ON or OFF. when single contact mode is set, you can choose between the upper and the lower contact. (same as at MIDIO4). The MIDI channels are fix. Pedalboard = channel 1, manual 5 = channel 14. Additonally you can connect up to 128 switches (and / or push buttons) and up to 4 potentiometers (swell pedals). The potentiometers will be connected to the stereo jacks sockets. Furthermore there are 6 mono jack sockets for connecting toe pistons. With an arbour-mounted circuit board this option can be extended to 12 mono jack sockets. The ports for the switches / push buttons are arranged in 8 groups of 16 pins (X1 -X8). There is a difference in processing the signals of push buttons and switches. You can choose how you want to configure the HW2 Extension. Default 0 = 128 push buttons, default 1 = 128 switches. And of course there are also mixed configurations available. As for example 108 push buttons + 16 switches, or 92 push buttons + 32 switches etc.

ADAPTER BOARDS

KOKO 2
- UHT - KEYBOARDS can be connected by an adapter to almost any electronic key scanning system. So, high-active and low-active are also served like different connector pin assignments.
64 to WAGO
- This adapt board converts signals from 64pol. flat cable IN into 64 screw connectors (or clamp connectors) OUT. 64toWAGO is passive and works in both directions. There’s no power supply needed. So, the screw connectors (or clamp connectors) can also be converted into a 64pol. flat cable output.

INTERFACES FOR SINGLE OUTPUTS

Electric consoles of pipe organs usually require a contact switching for each single key. For this purpose the 2 interface boards S402061 DS and S402061 DSP have been developed.

S402061DS
- The UHT - S402061DS interface transforms the matrix into single contact signals. At inputs or load resistances the interface can operate with an operating voltage of up to DC 30V. The PCB has a special design, so the interface can easily be mounted at the frame of the keyboard. The interface will be connected to the organ electronic with a 64 pol. ribbon cable. The pins 62, 63 and 64 are not assigned, so they are free configurable. With jumpers to be set, the contact can be selected. (point of speech = upper contact or lower contact) The outputs are low-active. The COM voltage of the load resistances is switched to GND. An adapter board with screw connectors is available as an option. S402061DS can supply single outputs as described above AND MIDI-OUT at the same time. (additional MIDI-Encoder required). DS means „dual scan“
S402061DSP
- The difference to the S4020DS is, that the S402061 DSP interface gives high active signals when a key is pressed. As for example 24V are connected to COM -> 24V output will be supplied.

KEY REBOUND

If it is desired to place the pressure point and contact threshold as near as possible to the start of the key stroke, we recommend the key rebound interface that we have developed specially for that purpose. Each key oscillates at the upper limit stop when it spontaneously returns to the rest position. This results in falling below the contact threshold one or more times which, in turn, causes unwanted repetitions of the note. Unfortunately, this physical law cannot be negated. In the case of the key rebound, renewed activation is suppressed for the duration of the rebound. This period of time can be set on a regulator. If an excessively long time is selected, the maximum key repetition frequency is reduced. This is usually very high on UHT keyboards. The organist should find his or her own compromise here.

CONTACT SYSTEMS

UHT - DOUBLE HALL CONTACT SYSTEM FOR KEYBOARDS

- The wear free contact system can be used for keyboards with up to 61 notes. (also for 54, 56 and 58 notes)
- Each magnet can be adjusted in it's height, so the point of speech is equal at every key. Additionally the contact rail can be adjusted globally in it's vertical position.
- Example of an old keyboard retrofitted with our contact system
- Example of a mechanical action keyboard equipped with our contact system

With any of our MIDI-Encoders, interfaces and adapt prints it can either be used in the single contact mode (NOTE ON/OFF) or in the double contact mode (velocity. The according magnets and mounting brackets are included.

UHT - DOUBLE HALL CONTACT SYSTEM FOR PEDALBOARDS

- The wear free pedalboard contact system can be used for pedalboards with up to 32 notes. (also for 25, 27 and 30 notes)
- Due to the long holes, the contacts can be adjusted in it's height, so the point of speech can be adjusted.
- contact system fitted to a pedalboard

With any of our MIDI-Encoders, interfaces and adapt prints it can either be used in the single contact mode (NOTE ON/OFF) or in the double contact mode (velocity. The according magnets are included.
