They said in the video, 32gig SdCard came with Air Sonivox drum sound is included, and the units does not need SD cards to imports sound, you can do it via USB without SD cards, at the same time with a SD cards, you can have 20 more kits.
-Sample Pad Pro have little advantage on the triggers, 8 trigger pad + 2 pad triggers outputs + bass drum triggers output and hihat , total of 11 triggers + hihat.
-Sample Rack have 8 outputs + bass drum triggers output and hihat, total of 9 triggers + hihat.
I am wonder why the Sample Rack have 2 less triggers capabilities, should be the same.
I hope there is multilayer velocity switch and reasonable amount of memory space for the samples.
