Hi my name is derick, and i have just bought the ez rollers and dj stakka highly acclaimed sample dvds. For everybody's information, the samples in the ez rollers dvd is awesome, but i can't say too much about the instruments. most of the instruments has only one or a few samples mapped across the keyboard, so the notes are stretched differently in time for each note like a regular sampler and of course time related modulation (like lfo modulation) are different in time for each note too. I am hoping to get some advice if i should use the samples or not because when i hear drum and bass, most of the instruments with time related modulations are in time, which can only be done with synths. and with the sampler the notes get cut off for each note differently due to non multisampled dvds. lastly, i wonder does the pros in drum and bass use samples instruments (when it is not multisampled)or at least ez rollers himself uses his own sample dvd when it is not multisampled. Basically, if anyone buy the dvds i mentioned above, it is not multisampled and has the problem i mentioned above. i wonder if i wasted money on the dvds???
