Re: Volume Control of Midi during playback

2005-12-11 by bnbwv

Spencer,

In trying to reduce the volume on my old wagon grand, there are two 
complications.  First, the volume controller (7) has no effect on 
hammer velocity (volume).  Second, if you just scale down all 
velocities, the softer notes won't sound at all.  You need to map 
velocities into a range from a low of around 25 to a high that 
depends on the 'volume' you desire.  Your MIDIMOD program is what is 
needed, with the mapping being done on the fly rather than as a file 
in / file out operation.
