Alt.callahans Reel (not to be confused with the quite different Callahan's Reel) is currently first on the list.

This is a live MIDI recording: ie Midinotate Composer was recording the MIDI data direct from a performance, onto a double (pianoforte) stave, with the COmposer metronome running in the performer's ear as a click track.

The actual playing was a one-shot run on a single keyboard set to piano (both hands), strings (left hand) and viola (right hand) so the performer was listening to the string effects and varying his keyboard playing appropriately to give the right string phrasing. The touch and fingerwork necessary to do this was of course recorded in the piano midi track.

So to recreate the sound on playback, the two piano staves were copied in composer to another pair of staves, the bass (LH) of which was set to strings and the treble (RH) to viola, and viola! er, voila! the midi playback is the same as the original performance, same speed, same expression, same dynamics, same fumbles. (only works properly on the same machine, of course)

While I will edit this piece, it was just too much fun to let pass. It was fun playing it too, the input ended up twice as long as intended...

It's also a good demonstration of the capabilities of the unbelievably cheap Medeli 710C keyboard when played hard and fast and heavily reliant on its touch sensitivity.

(and for those wondering, alt.callahans is an amazing newsgroup full of shaggy dog stories, amazing puns, much virtual drinking and a lot of fun, based on Callahan's Place of science fiction fame)
