Cords is a chord sequencer. It allows to create 4 chords progression, and play them automatically linked to BPM or by sequentially playing on your keyboard. The resulting notes are scale filtered for further refinement, using yet another 4 steps sequencer. Very complex tonal progression can be accomplished combining both systems.

Cords inherits developments from (mainly) James Clark' "Driftwood Arpeggiator" (, as well as Peter Dines NoteOff macro and several other contributions to the UL.

There's still some bugs with hanging MIDI notes, and some notes being lost. Use the Panic button to reset all MIDI notes and clean annoying stuff...

Very good indeed ! Took a while for me to get my head around it, but very customisable.

This is great! I have a couple questions. Is it possible to make interface larger? I have to press my face up to the monitor to read. And would be great to include tool tips if possible. Not evident to me what everything does.

Works great driving Logic and its many great MIDI processors, such as arps, transposer, note-probability scripts, glissando-maker, strummer, etc. And it's pretty fun, too, with Adlais dropped in ahead of it to play the input notes:) Thanks again!
