Spent about an hour today testing Atlas and XO. Both are really fast ways to navigate my sample library and get a drum set up and running. I still think XO is a bit better at that. Both are competent sampler drum machines in their own right, offer multiple outputs, and will let me export midi or samples to my daw/other drum machine of my choice (which is good because I have and have been learning Speedrum for the past few months).
Thankfully, I have another week to demo both and see what’s what. So far, I’d say I could use Atlas by itself, but not XO because Atlas will allow me to pass in MIDI from FL studio and apply randomization to that, but XO will only allow for basic swing and only if I use the built in sequencer. Neither allows layers that I set up with round robins or velocity layers on a single pad, a-la FPC or Speedrum, however Atlas lets me drag and drop samples to speedrum easily enough. XO I haven’t figured that out yet as it wants to render everything to a folder first and then bring that back in for some reason.
Oh also, seriously who is making a paid drum sampler in 2021 that doesn’t let me reverse the sample on a pad XLN? Speedrum and Atlas are both cheaper and have this figured out.
