Several years ago, BFD gave away a fully functioning demo of BFD on the cover DVD of Computer Music with the only restriction that it was stereo out only. BFD normally has multi-outs that you can process downstream.

I found it to be very useful with one exception - either the closed or open hi-hat sample would not respond properly to velocity - you got one level and one level only.

I ended up putting that on it's own track so that I could tame it.

However, very nicely recorded and easy to use, though deep.

Jamstix - I have version 2 and have used it successfully in all of it's modes; jam to audio, jam to midi velocities, and as a drum sample playback unit. This is with a host that properly interacts VSTi with tempo cues, which PG products do not. There is something unique about PG products (perhaps the SMPTE coding capability?) that does not work properly with tempo locking VSTi like Jamstix. Also very nicely recorded and more affordable for additional kits than BFD.

Great customer support from Rayzoon/Jamstix. With the exception of the hi-hat funkiness on BFD - never had to contact them for customer support.
