(Cubase) midi drum map setup?

Are there any "conventions" that I should follow when creating my custom drum map?
In Cubase SX the default (and only) drum map "GM drum map"
has this pattern: C1, C#1, and then the same for D,F,G
Afther that comes A1, A#1 and after that is pretty much a mess...

Also I find that there isn't much "order" in it, the sounds arent very well sorted.

So, I think I would make my own drum map.
If I open DR-008 it's much more tidy:
all nice rows of C,C#,D etc
So I think I would make my drum map according to this:
first all the C's, then all the C#'s etc.

But is this a smart thing to do?  Making a whole custom drum map (that I think, however, is more handy then the GM drum map), couldn't this cause "imcomptabilities" of some sort?
Aren't there conventions or standards for drum maps or something?

And also, lets say for example I put the snaredrum on C1, but in the GM drum map it was E1, is there a way to "convert" my cubase project to the new map? Or do I have to copy-paste all the "lines" ...

Thanks for the help
 

I found this: http://midistudio.com/Help/GMSpecs_PercMap.htm
This also looks like crap to me, so I guess I'm just going to define my own drum map...



edit:
http://www.cmusic.dsl.pipex.com/ Here I found a tool which makes a cubase 5/sx drum map based on the contents of the pads in dr008.
Can't get it to work however, but mailed the author about it, and when it will work, it will be great I think  
edit: works now, program is great  

I think it's fine to define your own order. AFAIK the only time, or reason for sticking to another map is if it's the General MIDI one, and you are actually selling GM MIDI files of your tracks. Can't see any reason at all why you shouldn't use something more convenient for yourself, though.

yeah, I was somewhat afraid that if I would try a new instrument/plugin/... whatever that I would have problems because of my custom map.

But now I made my custom map already, is there any way of e.g. putting al the notes of C5 to E1 or whatever?

Because otherwise there will be a lot of copy pasting to do  

Maps only get implemented at the instrument (or virtual instrument) stage. So how easy it is to change the way an instrument responds to differerent notes rather depends on the instrument itself. Usually it's not difficult to alter the mapping, it's just a pain!

So changing the map means copy pasting all the notes...

Yes, you'd have to somewhere. Assuming that you've got your drum parts on Ch. 10, it's usually easier to use the maps that come with the sound source you're using, and alter the SW you are using for storing the parts. I believe that it's normal, if you are using any sort of external pads, to program the pad outputs to hit the already mapped sounds, rather than the other way around.

Ultimately, it doesn't actually matter which note is triggered, as long as it plays the appropriate sound. But on balance, I'd say that it was easier to leave the sound generator alone and alter what's firing it, than the other way around.

what's an SW?

[S]

what's an SW?

SoftWare, sometimes with a / between the letters, as S/W. Also, you get HW, which is of course HardWare. So if you were using Cubase, this would be a SW sequencer, and if you were using something like a Roland MV-30 (as I do), this would be a HW sequencer.

Oh ok, I get it now...

So I just change the drum map to how I want it, I all the rest is based on that...
First task tomorrow is copy pasting all the notes to right places (sounds pretty funny now   )

If someone knows a little program or whatever to make this task easier, plz let me know

Plogue Bidule claims to be able to do this, and there's at least one bit of SW here that claims to as well. It's called MIDI remapper, and I know nothing whatsover about it!

Bidule handles mici files, not cubase files, and the midi remapper has gone offline....(but it 'ld also only handle midi files)
But don't worry about, I'll do it the copy-paste way  
and thanks for the help.
