BBS stands for Bus Bar Scanner. This is the scanner for keyboards using switches with single common contact for all keys in a keyboard, like usualy used in older organ consoles. The BBS boards come in different sizes, most commonly with 64 inputs and as BBS32 for 32 inputs.

- converts contacts with common bus into MIDI keyboard.
- optional unlimited transpose up/down. Pressing both transpose buttons simultaneously resets
transposition to default note.
- optional MIDI channel change
- input for optional keyboard/pedalboard scanner adding 32, 64 or 128 keys each
- optional split, with different MIDI channel for lower and upper part
- works in battery mode (enters power down after some time to save battery) or external power mode
(works all the time at full speed). Specify power supply type when ordering.
- can work with bussbar connected to GND or +5V, with contacts normally open or closed, or with active outputs.
- when used with PC GamePort cable it requires no external power supply (normally open contacts only).

There is one scanner input, that lests you expand kesy range by additional 16 to 128 keys depending on type of scanner chosen. This way you can easy build 2 or 3 keyboard controller.
