Hi,

I have a patch(which I've attached to this email) that takes a root note from a MIDI keyboard and outputs four chords in that root key in a rhythm..it works fine.

Only problem is that if I want to play a melody over this rhythm track I cannot because when I press a key the whole tonal key of the backing is changed(because the backing rhythm track takes the input from the keyboard too).

How do I get around this...is it something to do with channels or devices? Am I supposed to specify 2 input devices in the command line when I start PD?...eg.. pd\bin\pd -midiindev 1, 3 -midioutdev 2 ???

I was thinking that the notes in the lowest octave would control the backing and the rest would allow me to play the melody...just want to know how to keep them separate.

Thanks, Marcus.
