hi there
- my first post searched through
the archives & couldn't find my question.
i'm actually a guitarist
that likes to play drums when ever possible.

i've been thinking
about putting together
an electronic drum kit for a few years now.
the drummer in my band
is using the D-Drum module and triggers
and replaced the original skins with mess heads.
sounds great-nice to play but
the price is a bit terrifing to my wallet

i like the mess head idea together
with the look of real drums.
i will probably buy a cheap peice of
junk 4-5 peice kit
and change to mess
heads and d-drum triggers.

the module/interface is the
bit of kit i'm not sure about.
sounds of the module
are not really important and as far as quality
probably will not compete,as the
computer will provide the sounds
(DrumkitFromHell superiour or B F D)

important is:

1. standard midi in/out ports.
2. a good control of the velocity parameters.
3. and of course price. :)

so if you have done a similar thing,
please post any suggestions.

thanks

phil
