I recently bent this Alesis SR-16 by adding a 16 point patch bay. This machine sounds a lot better circuit bent than it does off the shelf! You can find some great glitchy sounds inside this bad boy and the patch bay gives you near endless combinations.
The audio is direct from the RX-15 to a Zoom H4n – it can get a little loud and distorted at times so keep your volume low. I recorded from a single mono channel on the SR-16.
