Yeah, I second the microbrute. At times it doesn’t even sound analog, and can be very harsh/industrial, but it can also produce very lush tones. Plus, the onboard sequencer is nice when advanced by an external gate signal, especially if the gate pattern is a different length to the sequence on the brute. I’ve had a lot of fun cranking out some pseudo-generative sequences using it with a Beatstep, so I’d say the A4 would be even better as a controller!
