A bit of constructive criticism... writing "stems-up/stems-down" is basically writing two separate lines or parts on one staff. Meaning that each line/part must be complete in themselves without relying on information from the "other" line to make sense.
Your transcriptions are missing most all of the rests. The stems down bass/snare part in Kashmir reads as two 1/16th's (on the BD) followed by a 1/4 (on the SD). It is only by relying on the vertical alignment between the stems up-steams down parts are we able to infer the missing 1/8th note rest. This in actual practice makes this very difficult to read - and near impossible to sight read.
This may seem like nit-picking - because, of course, we can figure it out. Justaswecanfigureoutasentencewrittenwithnospaces. We can figure it out but it is a lot, lot harder to discern.
Further note - keep in mind that you can switch between one part per staff to two parts per staff (stems up - stems down) at will, even within a bar - without any label or indicator being necessary. But will in two parts - each part must be complete to be fluently readable
Getting Logic's score editor to properly notate and playback drums can be quite challenging. I get what you're saying about the missing rests and I'll see if I can improve the legibility on future attempts.
