I would go with an Make Noise - ModDemix and a Expert Sleepers - Disting MK4
Or a Intellijel Designs - Shifty and Disting MK4.
But if I had only 2 HP more space I would go for a
Tip Top - Folding processor
or a Doepfer A-110-6 (Trapezoid Tthru Zero quadrature VCO)
just my 2 cents (or was it 5 cents ? ) ...
