Usually Amp HLD value set to AUTO produces a longer decay than when set to 1.
When using a HLD value different form AUTO then if we do modulate it negatively either with the velocity, a performance macro, a scene, or the aftertouch, to achieve a shorter sound, if we go lower than 1 then HLD value will be set to Auto and the sound will jump from a very short HLD to a considerable longer one (YMMV).
So if we use just one modulation source it is ok, we just need keep HLD modulation lower than x=HLD-1 so it won’t reach 0. But if we use more than one modulation source, for example after touch and a scene, the combination of both could make HLD to reach 0 therefore Auto.
I know it is a very little silly thing but I think it is more logical/intuitive if Auto is avoided when HLD is modulated… and I bet it is extremely easy to achieve on the coding side.
What do you think?
