[Edit: Scrapped all the delay line considerations because none of them can do short enough delays for my purposes, which is stuff like instrument body modeling (violin = .02ms for a 500hz resonance), karplus strong, etc. I replaced it with something I can program my own algorithms with in PureData. Also I'll be able to do stuff like modal synthesis in 'hardware' without needing to buy a dedicated module (or trust anyone else's implementation). I'll also be able to upload my custom talking vowel filter that I already have ready to go (5 formants deep!) :D. I just hope the processor is strong enough to keep up. The Salt has a better processor but both audio in and out are only 44.1hz which is fine for final products but not for stuff that's still being processed.]

Hello all, I've been lurking this site for quite a while now and am considering pulling the trigger on (starting) a build in the near future. My budget is set at 4k, but I know the general advice is to purchase modules slowly. I've been playing with synths, virtual modular programs, and things like CSound and PureData for over 10 years so I do have an idea what I'm doing, how things work, and what my goals are. I will be extending off a Behringer Neutron which I've had for around a year now. I love the immediate and tactile nature of it, and find it way more inspiring than clicking around on a computer. It's also far more performable, and I don't have to spend hours trying to patch up a MIDI control interface to interact with what I create -- the knobs are just there.

This is the build to work toward, and I've outlined my goals and potential solutions to them below. I'm looking for feedback! If you see anything important I've overlooked, know of a more efficient way, or see separate modules that may be reduced to one single module I haven't thought of please let me know!

(note: the bitbox is not going to be in the rack. It's a placeholder for the blackbox which costs exactly the same)

Goal:
Primary: Physical modeling, TZFM, Utility holes in Neutron
Secondary: Generative

What the primary goal requires:
1 TZFM oscillator
a way to model an instrument's body
cover the most frequent things I wish I had while patching the Neutron:
1 full wave rectifier (to pair with neutron slew for an envelope follower)
1+ VCA
1+ EG
9000 attenuverters

Secondary goal requires:
Clock toys
LFOs
Sequencers
Quantizer
etc.

Choices (*frontrunner, current choice):
TZFM osc:
FM ogre

Only does sin waves but has a 's


Hi Logical Phallusy,

On one hand it's interesting to read your explanations (a bit like myself) on the other hand it's difficult to judge on what/where you need advice, input and/or feedback. Perhaps the best is that you summarise it in two maximum three lines and then below that mention the questions you have? I haven't come across any real question or did I overlook the questions of yours?

Some general information: I would add one extra row to the rack and keep that empty for adding modules in the (near) future. You still can stay within your 4k budget (going to be tough though) but you have at least the space to extend in case you need, and you will need that :-)

You mention the Rubicon 2 from Intellijel is expensive and indeed that's the case. I got this one myself and though it's certainly a good module but is it worth that kind of money? I am not sure about that, for less money and at least as much fun I enjoy my Make Noise - STO. Perhaps to keep in mind that larger/bigger/more expensive VCO/DCO modules doesn't mean automatically more fun to play with. Of course it depends a bit on what you want to do but your observation is right that the Rubicon 2 is (bloody) expensive and you might want to ask yourself if that's worth it for what it gives you. Best advice is to have it tested at your local dealer. Testing the modules before buying is the best what you can do; not always possible though.

Also generally I would advice to start with a simple setup of: 2 VCOs, 2 LFOs, 2 EGs, 2 filters, ring mod perhaps, noise?, VCAs, mixer and audio input/output module, that as a contrast to your choice of "quite sexy modules" ;-)

Good luck with your planning, as you mentioned it yourself already, start slowly with a few modules and build it up bit by bit, while gaining experience, that's indeed the most enjoyable way into modular. Have fun and kind regards, Garfield Modular.
