Re: [disklavier] Re: Volume Control of Midi during playback

2005-12-11 by Carl Youngblood

It seems like the algorithm being used is wrong.  If a note is already
soft, it should not be reduced to zero.  It should be reduced less the
further it is from the desired overall volume, until turning down the
volume doesn't change it at all.  Think of a normal distribution, with
the desired volume being right at the middle of the bell curve. 
Turning down the volume should bring notes closer to the center of the
bell curve instead of just subtracting uniformly from their
velocities.
