In HISE, every sampler has settings whether to play the notes as single shots (playing the samples in their entirety irrespective of the note duration and note-off data) or to follow the note-on/note-off data fed through the MIDI input.
Where are these settings exactly? I deleted my AHDSR envelope now and when I trigger that patch, console says:
! You need at least one envelope in the gain chain
you must have an envelope in the gain stage for every sound source, if you dont want the release to cut in then just set the release to the max.
