It depends on what you are musically aiming for from your euro expansion. This rack is weighted towards processing the 6 oscillator outputs from the subharmonicon and mixing them down to stereo which leads to the need for lots of attenuation/mixing/routing/ hence the pair of AI800 matrix mixers and jumble henge. Jumble Henge is fab for quickly filtering and positioning many voices into something coherently stereo. I have all the 6 oscillators available to tap into as they arrive into the rack via the Behringer system 100 173 gate/multiple module. I have a lot of great filtering options with Blades, 3 sisters and the 2 triple vactoral resonators (sounds like a QPAS) as well as spectral filtering/waveshaping with the LR4 and Tahn.
Stages and Tides provide the envelopes/LFO along with 2 dedicated looping ADSR modules I DIY’d. I particulary connect with Tides for adding macro organic movement to a patch or for rhythmic triggering. The joystick module provide hands on modulation chaos on any 2 chosen parameters and and I am DIYing a FSR strip and module to fit in the 1U at the bottom of the rack.
Harlequins Context is a relatively new module that I have just DIY’d but the plan for it is to enable me to cycle through stored harmonic intervals with the Subharmonicons sub Osc’s.
The big discovery whilst building this was how good Just Friends is, perfect as a source of related envelopes/LFO’s but also such a great oscillator in its own right which, I think, complements the sound of the Moogs.
TLDR my rack is very esoteric and this rack from spikysimon is much more sensible !
