a few more thoughts - depending on what other gear you have - a poly synth for example...

I would swap the chainsaw for a general cv - it's a eurorack implementation of general midi - so has loads of samples of real instruments - plus it can be expanded to be used as a polyphonic cv-> midi converter (possibly the best one out there for interfacing sinfonion with external poly synths) - & general cv will also double up as a percussion source!

agree with farkas - get vcv rack (although personally I dislike it) and consider a dc-coupled audio interface to interface the odular with it - these can be had for cheap - used RME interfaces or a bit more expensive and in rack es8/9

are you thinking of using the bitbox for drums? if not how are you thinking of using the metronome to 'add a cool drum transition at the end'?

building a mixer from scratch is a real pita - seriously check out the tex-mix - I really like mine!

I have something similar in terms of generative (marbles) and programmable (step fader, BSP - & thinking hard about a black sequencer) feeding a sinfonion (plus a pico seq - which I'm not at all keen on - for swapping song parts) for sequencing and maybe a couple more voices than necessary

you can check out my rack

which is something similar to what you are trying to do (NB left most section is mostly video synthesizer - some of the doepfer modules are used for both though) although this is slightly out of date - it's now spread over 8 cases not 6 as depicted

I agree with @farkas about going back to the drawing board too... step back as far as possible and start with what you requirements are - how many voices and what type - how do you sequence that, do you want programmatic or random or both - do you need percussion - much better in terms of price/features to go outside the box...

I'm looking forward to @Lugia's take they are often very interesting!
