thanks for replys all , i think the main difference between DAWs(ableton, cubase etc.) and modplug is 16bit vs. 32bit ,i have made some experiments with simple drum programming in ableton and then modplug. using the exactly same samples(tr808kit 44.1khz/16bitwaw). i put the drums to simpler with no effects and same samples to modplug . for me ableton sounded more bright, crunchy and punchy.
i know, i could get that same punch with modplug, but with one vst for one channel is not really good for that, i love modplug but this issue is annoying me to death. maybe i can start using vst instruments since those suppose to be 32bit. so if you know good vst samplers hook me up!!!
ps. and yea, good music is not about the soundquality, but some types of shit really need that digital brightness,dynamics, etc etc. forexample minimal techno, dubstep etc. etc.
