There are many different sizes of keyboards available today. But generally keyboards range in size from 25 notes, on a small synthesiser, up to 88 notes for a grand piano.
This keyboard encoder is capable of encoding any number of momentary action, push to make, single pole single throw (SPST), switches from 1 up to 72 to produce the equivalent MIDI note-on/note-off data commands. The keys are arranged in an 8 x 9 (72 keys) matrix.
This keyboard encoder is capable of encoding any number of momentary action, push to make, single pole single throw (SPST), switches from 1 up to 64 to produce the equivalent MIDI note-on/note-off data commands. The keys are arranged in an 8 x 8 (64 keys) matrix.
This design is a single board MIDI encoder capable of encoding two 61-Note keyboards and one 32-Note Bass pedal unit. This design could be used to convert some old organ keyboards to MIDI.
This design is a single board MIDI encoder capable of encoding three 61-Note keyboards, one 32-Note Bass pedal, 40 Thumb Piston switch inputs and 3 Expression pedal encoders unit.
This switch encoder design is capable of encoding any number of momentary action, push to make, single pole single throw (SPST), switches from 1 up to 256, and 16 potentiometers on MIDI Channels 1 and 2.
This design is based on the requirements for a 25 Note Velocity sensitive Fatar keyboard. The keyboard encoder is arranged as a matrix of 8x5 (40), but only 25 keys are wired.
This design is based on the requirements of a 37 Note Velocity sensitive Fatar keyboard. The keyboard is arranged as a matrix of 8x5 (40), but only 37 keys are wired.
This design is based on the requirements of a 49 Note Velocity sensitive Fatar keyboard. The keyboard is arranged as two matrices of 8x3 (24), for the Left Hand Bass range. Also an 8x4 (32) matrix, for the Right hand Treble range.
This design is based on the requirements of a 61 Note Velocity sensitive Fatar keyboard. The keyboard is arranged as two matrices of 8x4 (32), for the Left Hand Bass range. Also an 8x4 (32) matrix, for the Right hand Treble range.
This design is based on the requirements of a 76 Note Velocity sensitive Fatar keyboard. The keyboard is arranged as two matrices of 8x6 (48), for the Left Hand Bass range. Also an 8x4 (32) matrix, for the Right hand Treble range.
This design is based on the requirements of an 88 Note Velocity sensitive Fatar keyboard. The keyboard is arranged as two matrices of 8x5 (40), for the Left Hand Bass range. Also an 8x6 (48) matrix, for the Right hand Treble range.
This 25 note keyboard encoder is capable of encoding any number of momentary action switches from 1 up to 25 to produce the equivalent MIDI note-on/note-off data commands. The keys are arranged in a (6x5) matrix. This unit can work in standard MIDI mode and via the USB connection.
This 128 note keyboard encoder is capable of encoding any number of momentary action switches from 1 up to 128 to produce the equivalent MIDI note-on/note-off data commands. The keys are arranged in a (16x8) matrix. This unit can work in standard MIDI mode and via the USB connection.
