MID Bass Pedal

Posted on Feb 4, 2014

The MIDI Bass Pedal uses the MIDI keyboard encoder (MKE), which is capable of encoding any number of momentary action, push to make, single pole single throw (SPST), switches from 1 up to 128 to produce the equivalent MIDI note-on/note-off data commands. The encoded switches are wired via IN4148 diodes, see schematic circuit diagram.

This unit can be connected to new bass pedals or it can be used with an older non-MIDI bass pedals by using magnetic/reed switches to isolate the old and new scanning circuits. This will allow the older bass pedal synthesizer to continue to operate as normal while also providing a MIDI output.
