Well not exactly MegaDrum.. but I think it fits your need.
Here a a tutorial to use guitar hero world tour (GHWT) drums on PC... there is software to convert the game controller data to MIDI for use in whatever sampler you like. Note you need the ps3 / ps2 wireless dongle not the xbox one)
http://pctutorialsonline.net/index.php/ ... on-pc.htmlI have done this. its velocity sensitive etc, but pads are acoustically noisy and the kick pedal is rubbish. There is only two cymbals + 3 pads + kick (I would like to have extra cymbal so I could do HH, crash and ride but no) also there is no foot controller for High hat. A cheap way to add this would be hack a usb joystick and diy a pedal.. there are a few HID to MIDI softwares around (usb game controllers use the HID usb profile)
Does not compare to MegaDrum + proper mesh heads. but its compact, fun, cheap (what other drum kit can you folddown and carry under one arm
I got one from my neighbours rubbish pile. just needed a new piezo on the snare pad.
ok but this software is windows.. maybe there is osX equiv ???
