Guitar-like transposing of a DIY sequencer with a PS/2 keyboard

http://chemiker1981.blogspot.com/ A sequence played by my DIY sequencer/synth is transposed by a standard PS/2 keyboard. This realized by a change in the software of the arduino µ-Controller based sequencer Syncuino. MIDI master is a Roland TR-505 drum computer, MIDI slave is the Syncuino. The Syncuino project is described here: http://chemiker1981.blogspot.com/2011/08/8-transposing-notes-with-ps2-keyboard.html
