I'd sell Clouds soon, specially with Clouds 2 in the way.

Any way, the E352 is a powerful voice, and with the Microbrute, you're covered there. Maybe a more hands-on sequencer like the Voltage Block (straight forward) or the Rene (more deeper and with cool live input)? Or maybe the Nebulae V2 or the Morphagene for audio processing, if you're not that much into melodic sequencing.

It depends, but it seems like the right direction.

I would just point: Pulp Logic 1U tile are not compatible with Intelijel ones!

Soo... you're here, after all.
