The FCB1010 can send Note On on press and Note Off on release so you can use it to trigger a sampler. I don't think it comes out of the box that way but you can program it to send notes. The pedals can be programmed to send any MIDI continuous controller including volume (7). If you haven't already bought one you might also consider this:
It's smaller and the layout is more like a keyboard if that matters, but you'll need a standalone pedal.

I've searched the website and seen many posts for the FCB1010 but cannot find the answer I am looking for.
I have the FCB1010 and I would like to use it to control a sampler eg a Roland SP-303 however I have read posts on other forums suggesting that this will not work due to the FCB not sending note on midi messages.
Is anyone here using the FCB1010 with a hardware sampler to trigger samples?
If not, is anyone using a different pedal/sampler arrangement that they could recommend? I am a keyboard and guitarist and want to be able to trigger samples on and off using the footpedal. If the volume pedal can be used to control volume, that would be great too.
