MIDI note-on velocity determines either the speed of your key movement or the exact speed of the hammer as it hits the string (depending upon which model of Disklavier you have).
MIDI volume (controller 7) has no effect on the wagon grand, MX100A&B, MX80, or Mark II.
Changing the controller 7 value for the piano part on a Mark IIXG or later Disklavier will result in higher note-on velocities if you set controller 7 greater than 100 and lower note-on velocities if you set it lower than 100. How much change is actually applied to the individual note-on velocities during playback is unknown.

Therefore, controller 7 scales up or down the note-on velocities of the piano as appropriate. Nothing more; nothing less.How is this different than changing velocity? What is the difference between velocity and MIDI volume on a DKV?
Sam(212) 684-3304*(Sent from phone - please excuse brevity and typos.)Let's back up for a moment.
When an instrument plays louder, the timbre changes, generally getting brighter. Therefore, we expect both a volume change and a timbre change when an instrument switches from soft to loud or loud to soft.When controller 7 is applied to electronic voices, its function is to change the volume of sound without changing the timbre. Going back to my organ pipe analogy, that is like opening and closing the louvers of a pipe chamber, thus allowing the sound to get louder or making it get softer. It is also like turning up or down the volume knob on your stereo. If you are listening to your stereo and the instrumentalist is playing loud, you can tell, even if you have turned the volume down. Why? Because you can still hear the timbre change.Ideally, controller 7 would reposition the lid of your piano. That way, it would change the volume of sound without changing the timbr e. Obviously, that is not practical. Therefore, controller 7 scales up or down the note-on velocities of the piano as appropriate. Nothing more; nothing less.PianoBenchOn Feb 18, 2014, at 12:09 PM, Skanter123 wrote:Pianobench, thanks for this.To be clear, what would controller 7 control n the DKV if it were able to?
SamGood morning, everyone.
Sam, I did a little digging and checked out the MIDI implementation chart for the Mark II. The Mark II does not recognize controller 7. Recognition of controller 7 was a feature that was introduced with the Mark IIXG.The wagon grand, MX100A&B, MX80 series, and Mark II do not recognize controller 7 for the piano tracks.Regards,PianoBenchOn Feb 18, 2014, at 1:53 AM, Skanter123 <skanter123@...> wrote:I said that lowering MIDI VOLUME (not velocity) produced no affect. I 'm not sure how ch anging MIDI volume (controller #7) affects the DKV if at all. Is it supposed to?
