Hi all,
Above is my finished attempt at a modular I'm aiming to build. I've quite a lot of experience with DAW's, VST's, drum machines, and even some classic hardware synths, but this is the first modular synth I'll be putting together. I feel like I've done my research but I'm sure there's a ton I don't know, and would appreciate hearing some input, finding out where the holes are, etc.
The aim for this modular is for IDM/techno/electronic, working with Ableton to generate MIDI and an Analog Rtym drum machine - mainly studio focussed. The goal would be to take MIDI out as CV from the ES-9, run everything around the modular, and then back into the ES-9 so that I can record individual tracks  - hence no sequencer. This will allow me to do after-effects processing on the individual channels within Ableton (e.g. reverb, sidechaining, etc) - hence the limited number of effects in the rack. The modular would not be built all at once - I would aim to start with about 50-60% of this, mainly so I can learn each module.
Thoughts on the rack:
- MIDI would come out from the ES-9 into the Pam's, to clock the whole rack. I've added a few other utilities (clock divider, mult, sample & hold) and then the Marbles clone Pachinko - this would allow me to use MIDI sequences from Ableton but still have some measure of randomization and shifting. 
- I'm aiming to have one pure analog oscillator (Instruo Ts-L), and I decided to add the Instruo VCA for it, for good measure. The Plaits clone because gives a wide range of sound options, and then the Piston Honda because I love the sound, I'd like a different form of synthesis (wavetable), and because I can use it to feed other audio through it - not just as a pure oscillator. 
- The Quadrax with expander (plus the Maths below it) seems to give me quite a lot of options on envelopes/LFO's. 
- Morgasmatron provides options to run the filters independently or together, which I like the flexibility of - plus I like what I've heard from them. 
- The 2 noise engineering modules plus the Happy Nerding Tritone are aiming to give me some options on saturation and distortion - also the Noise Engineering modules, both the filter and low-pass gate give me another option on filters (and I would like at least one LPG module - I like the short decay "ping" sounds). 
- The Doepfer VCA's I'm a little unsure of - I know I will need a number of VCA's, and this seemed an effective means of using them - but another alternative would be 2x Happy Nerding 3-VCA's, or the Quad VCA from Intellijel 
- The Morphagene - I just love the sounds of these, and it gives me lots of options to gain anything from background ambience to effects. 
- Finally the ST Mixer would allow me to mix some sounds together before the ES-9, and the Disting is really just to allow me to test out different functions / fill any gaps that I may have. 
The questions I would have is - does this fundamentally work or is it a mess, are there any other module recommendations, and finally I do have some blank spots left - which I'm assuming I'll end up filling with utilities - but are there any recommendations for these?
Open to any and all criticism!
