This little board is a standalone controller for 32 potentiometers or analog inputs. It converts knob movement or voltage change into MIDI. In addition it has one expander input. This would be typicaly used to connect numeric keypad for setting up all the features, but you can connect also one of the keyboard scanners, and use it as both - playing keyboard, and MIDI settings entry. You can also add POT32X in series to get 64-knob MIDI controller.

Features:

• onboard 32 potentiometer inputs
• preprogrammed for use with any synthesizer, or software synth you require, if you're not comfortable with doing MIDI setup for yourself
• user defined MIDI channel separately for each pot
• user defined MIDI event separately for each pot
• available MIDI events: Control Change, Pitch Bend, Channel After Touch, Program Change, note-on, note-off, glissando
• user defined independent transposition for each keyboard if keyboard scanner is added
• knobs can be assigned as Velocity source for all notes, as well as rotary transpose controls with +/-4 or +/-8 semitones range
• Program Change messages can be also generated via numeric keypad
• all settings stored in nonvolatile memory
• onboard DIN-5 MIDI-OUT socket
• requires 5-12V DC power supply, about 1-15mA current consumption depending on number and value of of pots used.
• optional auto-power-off feature for battery powered system - on request.
• dimensions: 40x55mm (1.6''x2.2'')

The board shown above has two 20-pin IDC headers. Each takes care of 16 potentiometers. 4 of 20 pins in each header are used to provide ground and power supply for the pots. There is also 1 small connector for expander/scanner, and, of course, MIDI OUT socket.
Without anything else except power supply, it can work as MIDIfier for 32 potentiometers. But if you ever want to change the MIDI settings yourself, it needs additional keyboard scanner connected, or better - a special numeric keybad. The user could then set MIDI channel and MIDI event for each of the pots individualy. Things like MIDI channel, controller type or Program Change message can be entered as numeric values. This additional scanner can of course work also as typical music keyboard. Even when using the special keypad, the buttons will generate notes when the board is not in edit mode.

With additional expanders the system can be freely upgraded to a larger one. POT32 can work as controller for couple of pots, or big system with over 128 keys and 64 knobs. It's only a matter of plugging appropriate type of expander/scanner.

POT32 price: 50EUR
compatible numeric keypad (needed only if you want to program MIDI settings yourself): 20EUR
