Before buying the FC300 , I've checked the Behringer but it doesn't send Note On/Off like the FC300. Only program change and CC.
(Edit; Check it out , there is a firmware update on the 1010 maybe now it can, not sure )
Later , I bought the VB99 and was really happy to have the FC300 but that is another subject!
I was trigging songs Intros and special FX , my drummer was trigging FX with an Octopad. When the latency on the CPU set to minimal , the latency was hard to tell , even for my drummer.
Have to have a powerfull CPU to do so......but you have hardware sampler , so , no latency here.
