Tube-Town EZ-Board Twin Relais PCB

Microcontroller-controlled MIDI switcher for channel switching or loop switching. Operation can be performed either via MIDI or a footswitch (momentary switch).

!!! UPDATE !!! With the May 2019 update, the following adjustments were made to the module:

• The large relay board has been removed and is no longer included in the kit, as a wide range of different relays with carrier boards is now available, offering much more flexible applications.
• The documentation has been consolidated and is available as a PDF download directly with the kit.
• The microcontroller with the firmware is no longer included in the kit and must be ordered separately depending on the desired version.

These changes allowed us to offer the kit in a more universal, flexible, and cost-effective way. More short information and software on the >>TT-Midi-Switcher project page
