Velocity has just been implemented to my Browser-Based Hex Keyboard
HandsEarsEyes.Fun > Ears > Hex Keyboard
Velocity if off by default or it works in either of 3 ways :
1A- Note holding time (to be coupled with release:off) : the notes starts out at 20% volume and gain up to 100% in .25sec
1B- Right-click note holding time : same as above but only on right click; can be quite good to play alternate high and low notes using the 2 mouse buttons, provided you take care not to hold for long on the right side...
2- Mouse Wheel : Volume starts out at 100% and bending it down will have future notes played at current changed volume (notes already playing not affected).
