Let's see if I can post this without erasing it this time...
OK, reworked the Boland entirely, mainly to get this closer to the actual 100M architecture.
I changed the MIDI interface for sizing reasons while keeping much of the necessary functions. The power was switched to a 4ms Row 40, which NOW gives you twice the current capacity than the modules, plus I trust 4ms's power circuits more than Uli's. This lets your P/S loaf along, generating less heat and experiencing less strain overall...which you want. Other than those, the only other non-B. module left is the Clouds clone; I chucked the Distings and the 'scope so that you could have a second pair of VCOs for even better doubling/detuning results. Plus, I added the CV mixer/portamento module to the bottom row, which should let you make better use of your modulation sources. I did toss the multiples, though, as this is just too small a build for having a dedicated mult (especially NOT one that takes up 16 hp!) and it would make more sense to use inline mults, plus this allowed the CV mixer. The only thing I regret here is that I didn't have space for the phase shifter/delay module, but those are functions you can add outboard.
As for the second rack...it really strikes me as more of a hodgepodge, really, and I don't think it'll work out all that well. For one thing, the Prodigy voice takes up loads of space for what it does. And at $3400 and change for the second rack...if you're trying for that Moog sound, consider a Subsequent 37 instead. For one thing, it's less than half the cost of the rack, and you're 100% in the Moog sound "pocket" with it. Also, the Sub37 has plenty of other tricks up its sleeve, such as a step sequencer and an arpeggiator. And the cherry on the cake: since it's duophonic, you can (in theory) use it to control itself AND the Boland rack, depending on how you opt to set it all up. Better still, if you can find a Sub37 CV used on Reverb, eBay, etc, that would up your connectivity between it and the Boland rack while STILL coming in below the original cost!
