Does anyone know of any sample pad devices that I can connect to my SP-404sx. The idea is to use this sample pad to trigger sounds from the SP-404sx. The sample pad doesn't need to have the capacity to hold sounds, it just needs to be able to be used to control the SP404s pads via MIDI. Ive seen the Sp404 controlled by MIDI here: and I am hoping to find something to trigger it with whilst using a drum stick. Any help would be greatly appreciated. Cheers.
