HW2 - EXTENSION

The HW2 Extension is developed to be used in combination with the Software „HAUPTWERK“. 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 Example

UHT - HW2

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 the velocity function is switched OFF 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.

 

HW3 - EXTENSION

Same as with our HW2 - extension, a 5th manual and a pedalboard can be connected, both velocity-sensitive.

UHT - HW3 Example

UHT - HW3

With the small DIP switches the velocity mode can be switched ON or OFF. When the velocity function is switched OFF you can choose between the upper and the lower contact. (same as at MIDIO4). The MIDI channels are fixed. Pedalboard = channel 1, manual 5 = channel 14. The main difference to the HW2 - extension is that lighted pistons and/or switches and/or electro-magnetic drawstops can be connected to the submodules HW3-X8. So the HW3- Extension is an output AND input module. It implements MIDI data. Commands are sent to the computer and as a feedback LED signals or impulses for drivers for electro-magnetic switches or drawstops are generated.
