The ASRX is a classic sampler/sequencer/drum machine/synth that was considered the only real rival to Akai's MPC series. I got this one new and it has very little use as, shortly after I got it, I moved abroad and couldn't take it with me.

There's links to some reviews below that say more than I ever can.

It is noteworthy that this example does have the SCSI interface, which is invaluable, and is loaded with the version 2.5 operating system.

This is a great piece of pro audio kit and the starting price is incredible reasonable considering what I paid for it (and the comment in one of the reviews that the SCSI board alone is worth $300!)

I will post, and will ensure that the item is well packaged and protected, but due to the weight of this item collection would be better
