Topic: Velocity Curve Control Point Y Value

I've just noticed that it is no longer possible to set the minimum Y value to zero with the mouse on the velocity or pedal curves. I have previously been able to set the minimum velocity point to X=1, Y=0 with the mouse. It is no longer possible to set a silent keystroke (Y=0) with a minimum MIDI velocity of 1. I can right click on the control point and edit it manually but I can no longer drag the Y value to zero with the mouse.
This occurred some time between the release of PTQ 4 and version 4.5.1 and its still inherent in V 4.5.4. Settings that I saved at some time prior to 4.5.1 and all through Version 3 are ok.

Re: Velocity Curve Control Point Y Value

That's in fact a bug fixed to behave correctly. There's no such thing as velocity 0 - that's treated as a note-off.

Hard work and guts!

Re: Velocity Curve Control Point Y Value

It's not MIDI velocity 0 that's the problem. MIDI velocity 1 is the lowest note on velocity which I've always set to inaudible (Y value of zero), my keyboard will not produce MIDI velocity 0 no matter how softly I press a key. On a real piano if the key velocity is too low the hammer doesn't strike the strings so the note is inaudible and my (X=1, Y=0) point corresponds to this. In addition, even with an inaudible keystroke (MIDI velocity = 1) holding the key down will allow the inaudible note to resonate sympathetically with other notes. The problem is that you can no longer drag the Y value down to zero with the mouse and make a note inaudible if the velocity is too low.

With a Y value of 1, even if it takes 10 seconds to make a keystroke, the note is still audible which is not correct.
What I've been able to achieve in the past is MIDI velocity = 1, Y Value = 0 (inaudible) but the held  note will resonate in sympathy with other notes.

Re: Velocity Curve Control Point Y Value

With my 4.5.4, if I set the mouse pointer exactly upon the graphic's equivalent to the ribbon running the length of the inboard keyboard in a material piano, and click, the note descends, but is silent. That in spite of registering with a vertical histogram-bar displayed leftmost and hard next the Y axis.

Outboard of that position, the note sounds and the histogram-bar is no longer hard left of the Y axis. And as the click-point outboard along the key's length, so the position along the X axis of the evoked histogram-bar. Thus key-outboardness  is being made the graphic's analogue for the velocity parameter. By what ED tells us, zero is not a parameter value. 

Continuing the analogy for zero velocity, the ribbon area would be appropriate for no-sound, and its associated histogram-bar (which fades, amusingly).
