reMIDI (pronounced 'remedy') is not another music theory MIDI effect plugin. It’s the very first MIDI sampler. It literally cuts to the core of the problem of finding inspired musical materials by providing harmonies and melodies that are proven to work – enabling you to sample the royalty-free compositions of past greats (Bach, Chopin, Gershwin, etc).

More in the mood for modern? No problem – You can use reMIDI to get the most out of your purchased royalty-free MIDI loops.

If you can sample audio to help kickstart productions, why not sample midi? You can isolate melodies more easily than audio recordings and you can even extract all the chords used! Best of all - you get to choose the instruments.
