Alesis SR-18 Drum Machine MIDI I/O Sept 25, 2017 22:17:05 GMT -6 Quote Select PostDeselect PostLink to PostBack to Top Post by jeromemason on Sept 25, 2017 22:17:05 GMT -6 Handy to have around. I used it to create my own samples and as a trigger once. Has some really killer sounds and is a breeze to program your own perc with. They sell for around $180. This one is missing the PSU but runs forever off the batts in it, but I'm selling it for $125. You pay shipping in the lower 48 US. Thanks!
