My problem with the Alesis drum modules, has always been that they have a boatload of almost useless sounds in them.
AQ few of the kicks will work okay IF you process them, and some of the snares are okay, and a somewhat realistic snare sound can be achieved if you gate, compress, EQ and add some reverb to it.
The Tom and cymbal sounds are useless in my estimation...the hi-hats are okay, but the crashes and rides just plain stink.
Now, my question is this:
WHAT are you using this unit for?
Are you a Key player using it for drumsounds (i.e., MIDI)?
Are you a drummer triggering?
Take a look at the V-drums sound modules.
The bottom of the line goes for about $450 and it kicks, OR if you are programming, get a sampler. I sold
my Akai S-2000 s/e (studio Edition with 32 megs of RAM, 8 Outputs, and effects cards built in) for $450, and it had never left my home studio...I just never used it.
I'm a drummer, and my original intention was to trigger sounds from it from my kit using a n Alesis DM5, but the Alesis trigger to Midi interface is the slowest one available, making it literally useless for my purpose of live triggering.
If you are only using it to fire off the sounds contained WITHIN the Alesis units, the TMI is fine, but send it to an external unit and it's so freaking slow it isn't funny.
So, figure out what your budget is then look around because the Alesis stuff is almost "pre-historic", considering what is available these days.
