MIDI/USB 13 NOTE BASS PEDAL ENCODER



Description:

The MIDI Bass Pedal Encoder circuit is capable of encoding 13 momentary action, push to make, single pole single throw (SPST), switches to produce the equivalent MIDI note-on/note-off data commands. There are also Octave Up and and Octave Down switch inputs.

One side of each of the encoded Bass Pedal switches are wired to a common Ground (GND) pin and the other side of each switch is wired to a different digital input pin. The MIDI start Note is set to C2 (MIDI Note 36), which is connected to switch SW1, then the switches follow continuously to the last switch SW13, which is C3 (MIDI Note 48). But any different start note can be pre-programmed if required.

Operation:

This unit can work in standard MIDI mode and via the USB connection, at the same time. It defaults to standard MIDI Baud rate of 31250. By replacing the original firmware on Mega8u2/16U2, the Arduino will act as USB-MIDI device (Standard Midi Class), you do not need to install additional device drivers on Windows, MaxOSX, and Linux, as the firmware acts as a device of Standard Midi Class. It will automatically install on the system as an Audio USB Device.

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.

Power Supply:

External power can come either from an AC-to-DC adapter or battery. The adapter can be connected by plugging a 2.1mm center-positive plug into the board's power jack. Leads from a battery can be inserted in the Gnd and Vin pin headers of the POWER connector.

The board can operate on an external supply of 7 to 20 volts. If supplied with less than 7V, however, the 5V pin may supply less than five volts and the board may be unstable. If using more than 12V, the voltage regulator may overheat and damage the board. The recommended range is 7 to 12 volts.


Features:

The MIDI/USB 13 Note Bass Pedal Encoder Unit consists of:
  • An assembled MIDI Arduino Board, including a suitable pre-programmed microcontroller,
  • The MIDI channel is preset to channel 3,
  • The velocity byte is preset to a value of 100,
  • The start note of the bass pedal encoder is from MIDI note C2 (MIDI Note 36),
  • Other MIDI channel, velocity and start note values can be pre-programmed into the firmware on request,
  • Octave Up and Octave Down switch inputs,
  • A 2.1mm power socket, and associated LED,
  • A MIDI 5-pin DIN output socket and associated series resistors.
The MIDI/USB 13 Note Bass Pedal Encoder unit requires:
  • a 9v battery or equivalent DC power source or via the USB socket,
  • Suitable key-switches or magnetic reed switches,
  • Suitable 2 momentary action Octave Up/Down switches.
