Yep...the price discrepancy on the Entry Point for the same functions (pretty much) as the A-119 just doesn't make sense, plus you lose 2 extra hp of space to it. Granted, it has that square-wave 'extractor', but if you're not inputting something that has a very pure waveform in the first place, or which has numerous pitches, that's not likely to function properly. Not quite the same thing as a proper P-V converter, which tends to be a bit pricier.
And if we're talking Erica mixers, have you had a look at their Black Output Module? Pricier, but you get a stereo mixer with CV over panning, 3 mono channels and one stereo, a master gain, balanced outputs + a headphone amp, and it only takes up four more hp. That thing is pretty serious, takes care of the output + stereo mix thing, gives you a proper stereo in for the Clouds. $150 more, but I think you get your money's worth on that, given that the Black Stereo Mixer is roughly $150 and a stereo output will run another $75-100 for something decent. Plus the panel width used should be the same.
(Later): OK, I banged on it a little...several modules went away, and the goal here was to jack the functionality up as much as I could in a small space. 6 EGs (two AHDSR, two ADSR w/ inverters, two AD), 6 VCA (Intellijel Quad ($10 cheaper than Mutable's) and two linears), 6-channel mixer for sources, added a Maths, condensed the effects while breaking them out a little for some separate processing. Kept the Clouds, added the Black Output v2, plus also crammed in a ring mod and waveshaper, and cleaned up the signal flow. Here 'tis:
Better?
