Thanks for the kind words! I just picked up a 4ms pod64x yesterday and will complete it tomorrow with a Quadrax and a Vowel! (Gotta update these modulargrids to their current status!) As you noticed, I have several (and adding more!). The BEST by far is the Synthesis Technology E950 VCO. Its sound quality is extremely good with very high fidelity—highly recommended! In contrast, the Flame and the EMY sound very over-modulated, crude, and rough (and not necessarily in a good way). The E950 needs no filtering to sound good. It sounds incredible all by itself.
