Thanks, Quantum_Eraser. Good call on the effects. I wonder if there's a way for me to squeeze something on the more basic side without breaking into that bottom level? I know there is a 1U digiverb module, so that may be an option. I'll definitely check out the ALM Tangle Quartet as well.
I always have fun playing wavetable synths, so I'll give those oscillators a look as a potentially better compliment to the Mother-32.
