Default How can I randomize the mapped MIDI notes on a piano roll?

Hi there,

I am looking to do something a bit strange but bare with...

I am wanting to somehow create a piano instrument via VST where the piano roll is constantly fluctuating its mapped notes to be random. So for example the 88 notes are physically the same however what those notes are constantly changes (C might be A for 5 seconds and then F# for 1 second and then D for 3 seconds etc).

Is this possible and if so what is the best way to approach it?

Thanks in advance for any help you can give

Thanks for such a quick reply!

Those extensions/plug ins are super cool however it's not quite what I was after. Sorry I should have been more clear...

I would like the MIDI piano roll to be constantly fluctuating in terms of mapping random notes to the original piano keys. I then want to be able to play a piece of music (reading notation) as if it was a normal piano however the keys will be constantly changing and so will be completely random and sound chaotic.

Does that make sense?
