OK - I've gotten all the pieces together, swapped the Rossum filter for something a little more fun (for me) and pulled a bunch of modules out of the Save Box for the modular sampler. The whole thing is based off a 1010 Music Bitbox - have I raved about that enough? I freaking love it, and I've mostly been tweaking/playing with a very small set of files (I haven't really started sampling or collecting specifically for this device yet). It hits the sweet spot of awesome and fun for me, and it also lives in the MPC mental world for me, so I'm quite happy.
I settled on the WMD Overseer filter, which gives me stereo coherence but with a simple, DJ-like interface. Sounds great, responds perfectly to modulation and has that funky tilt function. Love it! I'm also back to the Intellijel uVCA - still, to me, the perfect VCA implementation. It's like an old friend, and I never tire of using it. Combining that with the Supercell is a winning combo, since I often use the VCA for modulated modulations - and the Supercell/Clouds loves that action.
I ended up getting an Audio Damage Spectre - despite my deep-seated issues with those punks, and the fact that the module will never be supported. Again, I get stereo coherence (I think...) and some nice algorithms. Modulating the whole scene is that Quadra (I had to buy some jumper blocks to use it without the expander...) and a MantaMate, which gives me nice random stuff when nothing is plugged in, but also acts as a decent MIDI converter - and a host for the Manta, too. The Manta seems like a good option for firing off stuff in the Bitbox, but it also makes me wish for a good CV-to-MIDI (on 1/8") converter I could use to randomize access into that module.
Alas, you can't have everything.
It looks like I'll be using this for some sample action in my gig on the 22nd - unless I find a way to have the MPC handle this. One less piece of gear is always useful. In the meantime, this has become my sofa-modular, and I'm loving it to death!
