Hi Diego,
Nice rack you got yourself planned there :-) I did nearly the same thing as you did, though instead of Erica Synths, I took a Doepfer starter set and “uncoupled” here and there a few modules and put my own likings in it. It resulted in a set that was double sized and not many of the original modules left of the starter set :-)
By the way, I am jealous about your Octatrack. I had a good friend a week ago here who brought his Make Noise 0-coast and his Octatrack; together with my modular system we got some interesting and nice results. Very nice device that Octatrack if you take your time to learn how to use it, good stuff Elektron. I consider the Analog Four but I am not so sure, I want to see what Hydrasynth comes up with and then will take it from there most likely.
Back to your rack :-) Here a few things you might want to look into it and/or to (re-) consider it:
You got quite a few Pico modules planned, 3 HP width, I feel is a bit too small. I got a few Pico modules, in principle I am okay with them, they are good however once you got them patched full with cables and want to reach the knobs then it’s getting less comfortable, just too small. Similar opinion I have about modules of 2 HP width. I also got the 8 Multi module, it is just a buffered multiple so without knobs and then the width (4 HP) is just about acceptable for me but it shouldn’t get smaller. But hey, that’s just me. Anyway, I see you put some of the Picos near to each other, perhaps you should put here and there a module between them to make it more comfortable to use them.
I see one ADSR, the Doepfer A-140v, I got myself the A-140 (the standard one), is a good module and does what it should do: being an ADSR :-) Though in your setup I would go at least for one more envelope (if not more). I have for example the Erica Synths Black VC EG (with the expander), I love that module, you get the usual ADSR however each A, D, S and R can be controlled by a separate CV (thus 4 CVs). The extension provides you a separate output for each of the stages: A, D, S and R. I use this module pretty much and I am really happy with it. You might want to consider that as a second envelope. And/or another envelope you could consider is the Erica Synths Black HADSR EG, I also got that one and is a nice module too that includes the Hold phase and you got a switch on it to use it either as a HADSR or as AHDSR. Yet another triple-switch for loop mode: ADSR, AR or off. I can recommend that HADSR EG module too however note that this module can’t be controlled by CVs
Not so sure why you want to have that Black Mixer? You got already a Doepfer A-138p (I got the standard non-vintage version and I am happy with it, I can recommend it), so why do you need the Black Mixer for?
Talking about that A-138p mixer, are you sure that’s going to work with the Erica Synths Output Module? I use the setup Doepfer A-138p together with the A-138o output module and that works just fine, so perhaps you should reconsider that Erica Synths Module and perhaps instead use the A-138o? The A-138p can be daisy chained with another A-138p so that’s why I don’t think you need the Black Mixer, do you?
I notice a few double modules, nothing against it if you have plenty space but you don’t have much space left, so do you really need two Pico Modulators? And two Pico Logic?
In the same context I noticed that you have one Pico DSP and the Black Hole DSP v2, I would go for the Black Hole DSP v2 and leave the Pico DSP out, so you can reduce a bit on the Pico modules, I feel you got a bit too many of those Picos; but that might be just me. Or do you really need a second DSP module, i.e. that Pico DSP?
Similar you might wonder if you need that Pico Attenuator module, you got already that Black VCA (got it myself too, nice module, output could be at times a bit stronger but otherwise a good module) and you got already planned that Doepfer A-138p, so already two ways of reducing the signals if you like, or do you expect somewhere such a strong signal that you must have a separate attenuator for that? The Black VCA (accordingly to the manual) got an improved attenuator :-) The In Level pot-meter can be used to reduce your signal if you need that.
Once you got the Make Noise Maths, the Erica Synths Black Hole and the Dual VCF please let me know your experiences, these are on my wish list too :-)
The Erica Synths Octasource is a fantastic crazy bastard ;-) I have that module in my setup and for me it’s the craziest module (in a positive way this is meant) I have but I love it. It’s a psychopath of a module, it has 8 outputs each 45º in phase shifted (single mode) or you put it in multi mode and then any output can have any phase. I recently use this crazy LFO a lot in my setup, so you can make not so crazy modules a bit crazier by having their CVs controlled by this psycho ;-) Then I use yet another two LFOs to control the CVs (Wave, Phase and FM) of this Octasource, then it goes totally bananas! :-) If you then put the rate of that Octasource quite low, you get crazy but nice effects
What I am also trying to say with the above is that yes the Octasource is a good choice but you need at least one normal LFO as well :-) Preferable with multiple/simultaneous outputs so you can put that psychopath of an Octasource even more out of control...
Oh yes, and do yourself a favour please and get one more row planned, so 3 times 104 HP instead of now 2 times 104 HP, you will need that space rather soon than later and then you will regret if you stick now with just two rows. Don’t come with the excuse that you don’t have budget enough for that, then leave out first one of those fancy modules and put that money into that extra row
Sorry, one more, I am missing an Audio output module, so instead of that Erica Output, I would take the Doepfer A-138o and then an Audio output module from Intellijel (Audio I/O) for example, or Bastl Ciao or Befaco Output, something like that, to make sure you can go without worries (DC signals filtered away with such audio output module) to your external mixer or directly to your active speakers
Well that were my two cents of thoughts ;-) I am still a bit jealous about your Octatrack, together with Modular you might get yourself some interesting results!
Good luck with your planning and kind regards,
Garfield Modular.
