array of Boss RC-2’s/RC-20XL’s. I once made a footplayable drum kit with them [and realised I should just actually buy a drum machine].

otherwise, the Boss SP202 is the only thing I can think of but it’s still probably cheaper [and easier to hook up] to get an RC-2.

you’d sample it.
this is from memory (I haven’t owned an RC-2 in about a year- since getting my 2880, really) so forgive me if it’s a little hazy:
run a cable from the line out of your computer into the input of the RC-2.
I think it’s the “play/record” mode that the RC-2 needs to be in. the one with the function knob pointing straight up. Light should be off.
capture it like you would if you were looping it.
turn the function knob to “write”
hit the “enter” button- the light should flash for a little bit
turn the knob to the “loop/one shot”
hit the enter button – light should go from green to orange.
the sample should now play once through when you hit the footswitch.

for the sampling thing? not really. none i’ve come across, anyways.
for the looping though, there’s the DOD DFX94 or the Muza FD90. or buy an RC-2 used [prices seem to hover from $90 to $150]. or the digitech Jam-man solo, although I really hate the footswitches on these and they use a 9VAC power supply.
for buying a pricey pedal while keeping a woman happy, write her a song that you need THAT specific pedal for. It’s always worked for me.

New BOSS RC-3 and RC-30 announced at NAMM; 3 hours of loop time, 99 different preset slots, USB connector, will take WAVs up and over 1GB in size. E….PIC. Two channels on the RC-30 with individual faders so you can mix and fade two phrases at once, as well as sticking a beat over it. Even more epic!
