Ableton. Like in the topic, for example I have Spire or Sylenth etc. and in the clip when I'm changing the velocity it doesn't make any difference.. it's horrible because I've never experienced that.. What should help guys ? Oh, and in the Drum Rack it works...

OmG, I just checked that I have got velocity on 0% in Simpler :p on Drum Rack it works of course, on Nexus too but I don't know where I can find the velocity on/off or the percentage on Sylenth & Spire..

SPIRE

X­Comp – multiband compressor. It’s disabled when the knob is in its rightmost position;
Velocity – determines the amount of velocity sensitivity;
Volume – overall level.

Bottom right hand corner in Spire.


Velocity Modes:
● Key – each note in the arpeggio uses its own velocity value, determined by the current
MIDI note.
● Hold – all notes have the same velocity value as the first played MIDI note (until
released).
● Step – takes the velocity value from the step sequencer.
● Step+Key – takes into account both the step sequencer and MIDI note’s velocities.
● Step+Hold – takes into account both the step sequencer and the first played MIDI note’s
(until released) velocities.

You are welcome! Glad you got it figured out. Little things like that can drive you mad.
