User Controlled Orchestral Backing
on: June 23, 2005, 05:23:24 PM
I use the music Minus One orchestral backing CDs for learning Piano Concertos and wondered if anyone had an answer to controlling the CD speed so you can actually have the real live situation emulated as closely as could be expected. In a live concert, the conductor can follow the performers changing playing speed. On the CD backiing, the pianist must follow the speed of the CD backing and so you are locked into this one interpretation!

I envisage that a foot pedal connected to suitable control hardware can allow you to alter the backing Orchestral CD in real time as you play your Piano part so effectively "conducting the orchestra" and allowing for your personal interpretation.

Do any owners out there of Disclavier/Pianodisc or any other system know if this kind of functionality is available in their pianos?

Also, for what I wish to achieve are there any alternative suggestions that would be effective. It is critical to be able to control the orchestra as you play the concerto so that you are not locked into one speed and therefore interpretation.

All comments to further my quest would be very much appreciated

Possibility exists if the accompaniment was MIDI, and you have some MIDI controllers around that you setup to actively control tempo. 

You can do a time shift with Audacity (free), but this would be fixed and not flexible. 
As for the Music Minus One, they are wav files essentially.  Actively changing the playback speed (with constant pitch) of a wav file may prove to be quite processor intensive.
