Next, I built a BX-24 setup (using Netmedia's BX-24 Basic Stamp chip) that
converted analog voltages from a Sharp GP-202 Infrared range sensor and a 3mm ultrabright red LED into MIDI
continuous controller messages on channel 11, controllers 80 & 81. A patch in PD
(Pure Data) receives the MIDI data and
modifies some parameters of a sample (duration, start point) based on the CC values passed into it.
The next step is to create a matrix of red LEDs that can be row/column scanned, and thus have their analog voltages read by the PIC microchip and converted to MIDI messages that the PD patch will handle. |
