Hello all, pretty novice user of PureData. However I want to create some user defined chords making up to 8 different possible progressions for use with a hardware interface. The interface will be 'struck', and that would need to send a 'bang' i believe to Puredata in order to trigger the chords.

Can anyone suggest a relatively simple way of bringing the code to fruition; in context I will be utilising this with a arduino board in order to create a kind of instrument
