Well, more space = more...uh...more:
Majorly stepped up, with a lot of new things added. Ten VCOs now, and accordingly, a buffered mult was added in addition to some other passives. Two Plaits, plus eight Doepfers in two Quad VCOs. Different wavefolder with a suboctave divider. More mixers (the Levit8 was moved to allow it to 'split' for audio and CVs if needed). Potentially up to 14 envelopes (the addition of the Stages allows a lot of flexibility with envelopes and other modulation sources), with the Quadrangle adding complex staged/looping ADs x 4. Added a Shifty analog shift register to allow the Metropolis to arpeggiate out four step-shifted CVs from the single CV out. Switched to an EMW 4xADSR for the ADSR EGs, plus added an EMW 4-stage phaser and a Flame FX-16CV for stereo effects. Changed the Mordax to an O'Tool mk2 for space considerations.
Then there's that bottom row...a lot of change there: Metropolis is still present, but I added an 8-channel EMW trigger sequencer (no, no menus there...has a shifting track display with '0' and '1' for trigger on/off indicators...very easy to use, rather 909-ish) and a section of drum modules (TR-606 4-voice clone, 8-voice with Linn LM-1 hits, and an Erica Drums with 16-bit samples). Then a HUGE WMD Performance Mixer setup w/ mute expander...this gives eight channels w/ input VCAs, automatable mutes, two FX busses, metering and cue sends, and a couple of other tricks, this into a Bastl Ciao! with a second stereo in line for the balanced outs.
Note that this will not work on a standard power supply setup that MDLR Case puts in their cabs; it will require the extra Doepfer PSU-3 option, but with that, the power will coast along smoothly. And it goes without saying that this blows your 4000 EUR original limit all to hell...but it's way more powerful and capable than the original build attempts.
