Hi Gastonn,
Excellent advice by Garfield as usual, I would like to add my voice (no pun intended) to the "you probably will need a bigger rack" team. Let's see if I can explain why.
If you want to create a multi-voice modular system (so at least 2 voices), you will already need at least 2 sound sources, here I can only see the Dixie and the STO, excellent in their own right but using the Dixie as a VCO prevents you from comfortably using it as an LFO. How many LFO's you need is a question of taste but just Disting (+ maybe Dixie) on LFO duties is not nearly enough for me.
Sound source is not the only thing you would need more of, in my opinion:
- I would definitely need more envelopes, at least one for the filter. One could do without it, of course, but it would make me sad.
- I would also need another filter for the 2nd voice. Another module that could use modulation like LFO's and envelopes, most likely.
- Ideally, I would like a (cv controllable, if possible) mixer/vca to mix waveforms from the VCO's and get some timbre variation
Let's look at the whole project as well, how much of it could not be achieved with a more "traditional" synth like the Elektron Analog Four ? For now with this setup, I'm thinking "not much, actually", which would prompt me to suggest getting that synth instead if your only goal is having a few mono synth voices with "limited" modulation. You'd get an interesting sequencer, effects, a few more voices, audio via USB etc. Should you get the A4 instead of a modular system ? Maybe, perhaps not. My point is that in my opinion, for one to get into Eurorack, one should probably have (or plan to have) needs that could only be answered in modular. Or simply have a lot of money to spend I guess hehe :) In other words, for your setup to offer more than what can be achieved with a "traditional" synth like the Elektron Analog Four (which BTW is not necessarily a goal that needs to be achieved on the first iteration, but it's good to look at the foreseeable future too), you would most likely need more modules, hence more space.
You have some space left in the rack right now but not much and you said it yourself, the size "can be ok for now", so there is a risk that you outgrow this. It is my personal opinion that it would happen much faster than you anticipate, as it seems to be a common experience for most of us. Hell, I was a modulation freak before but not nearly as much as now that I got into Eurorack, I could have never anticipated that the format would challenge my synthesis and production techniques so much, but I guess that's what great about it. As a result, the rack I have now is very, very different from the first plan I made. More importantly, it's much bigger now that I learned to use my rack and realized I wanted more out of it. I had to buy a bigger case after buying a small one, which is définitely more expensive than just buying the big one straight away.
The risk of outgrowing your current space is enough that I feel I should encourage you to consider a bigger case like TipTop Mantis or Intellijel's popular 7U cases. At first, it will look huge and empty but I wouldn't be surprised if it gets filled eventually. The final decision is always yours, but I hope my comment will help you make the best decision for what you envision.
Have fun and make music !
