Logic MIDI routing problem

[paul md]

Hi, I've been using Logic for some years but never with MIDI.

I've just got hold of a Yamaha DTXPRESS drum machine and want to now
record in MIDI.

I've connected it to my PC using the midi in/out cables (the round 5
pin cables)
and can record and playback fine. My problem is that the sounds I hear
back are either piano or whatever and not my required cymbal/snare etc
sounds.

I've been through the manual, which I find a bit mind boggling and
have been trying to set up a mapped instrument for this purpose.

Each pad fires different notes, and by default they are set to the
incorrect noises I want to hear. For example, when I hit the snare
pad, I hear a triangle or something equally useless. I've found by
messing about that if I change the "output note" I can achieve the
correct drum noise I want to hear. I guess I'm rerouting the note so
when I hit a snare pad, the note assigned to snare also fires, and I
hear my correct noise. (Hope I explained that 0K).

All was going fine using this method and by rerouting each pad I've
created a drum kit that works... Except the ride cymbal!! When I
strike this pad, I hear a crash cymbal, no matter what I reroute the
note to (by changing the "output note") all I get is a crash cymbal.
This method seems to work for all the other drum pads except the
ride!!!! Seems very weird.

I suppose my question is why doesn't my snare want to be rerouted?

I also have the question, "Am I going about this completely the wrong
way??" in the back of my head.

I'm not that technical so any advice, please make it easy to
understand - thanks!!

Any help offered is greatly recieved!!!!

Many thanks

Paul.
