figured it out, for samples to come up in order they can't have more than one letter, they all have to be named something like S0-SXX, so having names like BD1-10 mixed with names like HH1-10 and SD1-10 will not work.
I also wish the manual would be corrected. 490kb is not the available sample memory and if you use too much of its memory the unit will become unstable, samples can get lost the next time you start the unit, sometimes the sequencer stops responding to input, it hangs when loading a pattern, etc. - so very serious issues can occur and the user might not know why. Around 455kb seems to be max limit after that you are beginning to push it.
Yes, i use S0-S31 for the samples that i currently have. Same name that will show up on the LXR screen itself.
Since the screen does not list the sample name anyways (it will show them as s0-sXX) it's not extremely useful to name the samples anything else than this before you put them on the SD card. Instead it's a good idea to write down on a paper (or in .txt document to have on your computer) what number relates to which sample. e.g
S0 - TR808 Snare
S1 - TR909 Snare (short)
etc.
Some other general suggestions (when i'm already at it);
* think carefully of what samples you will upload, make them have good variation.. Using two drum samples that sounds basically the same (if you just change the pitch slightly), is pretty useless. Since the samples will be a part of the patches it can suck to later decide you would have preferred other samples too, this will ruin the patches you made with the old sounds.
* extremely short samples can be very useful. The attack is much more important than the tail of the sample. You can "fake" the tail of a drum hit by using noise and filter techniques (and the envelopes, obviously)
* Just using a sample alone is boring and not very creative, mix it with other waveforms. This is how the Nord Drum works, you mix/match many different very short sampled sounds and a filter to come up with new sounds. Changing the pitch of waveform or sample just slightly can do wonders and might surprise you.
* trim the samples extremely well. I've seen a few patches uploaded here with samples and they are sometimes very sloppily edited i have to say. For a synth sound with slow attack it does not matter if you have 3ms of silence at the start, for a drum sound you absolutely don't want this latency added. Zoom in as close as you can when editing and do it properly.

With S0 you mean S zero?
