I have read a few people asking about arpeggiators, to arpeggiate the audio input signal.
I do not think that there is a plug in that can do this (please correct me if I am wrong), so I came up with the below pedalboard (tested with Bass guitar only so far) that provides an arpeggiator effect.
The arpeggiated notes and intervals/timing can be changed by changing the MIDI note values in the sequencer.
It sounds far better when single notes are played, chords tend to get a bit mushy.
I hope this is of use to somebody.
