A few options:Use Ignore release function in Kontakt (It should exist, It is in reaktor and kontakt is designed for drums). Some better (and playable) alternatives first:In the instrument parameters functions window on the left of the arrange window on MIDI THru or instrument channel, a few lines below quantize there is a function called gate time, you can quadruple all note lengths or try using them legato. you could also try to run an arpeggiator inline, quantize off, but fixing length to a usable length and turning repeat off. I'll assume you know how to insert an arp. I don't know if you meant a value of 2 pulses provide the entire shot or gated shot. There are also several ways to mod this once it is recorded.
