Pipe Organ Electronic Tremolo Controller
The Electronic Tremolo Controller is designed to installed in the console or chamber with the output driver transistor controlling a dump valve that is attached to the chest reservoir. The output transistor can switch up to four amps that switches the valve to Ground. The valve operation can be set for best Rate and Pitch with the on board trim pots. The Tremolo Controller can be enabled by either a Positive or Negative voltage which is easily set by two jumpers on the card. For long term tremolo control, turn to the TD-1 Tremolo Controller.
IDC-48 All in One 48 Note MIDI Encoder/Decoder-Stop Action Driver
Introducing the NEW Single Board IDC-48 Midi Encoder/Decoder-Driver for Draw Knobs and SAM's. The IDC-48 can control up to 48 Stop Actions and sense the Stop Actions switches, sending and received midi data to and from Hauptwerk. The single board configuration eliminates stop action wiring to a separate midi encoder and midi decoder location. Other Features include "Auto Pulse Length" which will supply voltage to the action coils for up to 500ms or as short as needed based on the action switch movement. The Smart Action function will send voltage to a stop if the stop is set to change in the combination action and TEST MODE that steps the actions in sequence make the IDC-48 an ideal choice.
