Re: Roland Octapad versus SPD-SX: What to do?
The SPD-SX also has 2gb of sample memory, so it's better suited to larger samples with decay, such as timps, crotales, etc.
No need to use the looping or sampling on the Roland unit, just use it for playback.
You obviously can use a computer, so you can make your own .wav files, it's easy. A lot of people use Audacity (because it's free) but I prefer a more capable program (I use Sound Forge, it's probably already obsolete...)
