help start my euro! w/ obligatory modular planner screenie!

Post by berfmurret » Tue Dec 23, 2008 11:44 pm

hi all!!

Image



so i am officially getting on my way with this eurorack. this will be my first hardware modular. i am starting off with 12u - two elby 6u sub-enclosures - mounted inside an ewi tourcase... powerone PSU, DIY busboards made from veroboard. modules i already have are the malgorithm, a143-1, a188-1 (512), afg, plague bearer.. i already have 2 wogglebug pcbs but who knows when those (or maybe just one) will come into fruition. as soon as AH gets more qmmg in stock i will be pulling the trigger on one of those.. as you can see a some of my rack might not be fulfilled for some time... the dual VCSs *crosses fingers what the bananalogue comeback will bring*.. the hertz donut.. etc.. so yes. much of this is still up in the air. i am thinking (hoping) it will take me a year to finish filling the 12u.

i feel like i need to pay more attention to more utility stuffs. maybe some more cv/logic goodies will help fulfill my bastard child west coast eurorack vision? my only amps are in the qmmg, and i feel like i want more mixer than the model 9... vc pan would be pretty sweet but the cwejman mixer is $$$$$$. i will have a couple of more multiples for sure.

... but i digress...

first i ask what module(s), after the qmmg, might be most beneficial for the beginnings of this system?

second, and more importantly - educate me! give me some gossip. give me some ideas. give me some gas!

hey!

some ideas:

Ring mod!

More clock divs, or some Clock Sequencers: then you can do subdivisions of the Comp outs of the 143-1 :sb:

Trigger Delay?

Normal VCAs - I'm loving the 132-3 with my 143-1s

VC pans - the 134-2 can be patched to do panning, I think :)

Yeah, amps and maybe a model12 to give the resultant cacophony a buzz-cut.

a TipTop Audio Z3000 Oscillator to offset the AFG.

it also gives you a lovely frequency counter that will come in handy.

I'll echo the "standard" VCA suggestions. The QMMG will certainly cover a great deal of VCA territory, but you would likely find unique uses out of a more standard VCA such as the Doepfer 132-3 or a Cwejman. The 132-3 and QMMG will cover your VCA territory admirably for some time and may be the only VCAs you'll ever need, depending on how your system or desires grow.

You may also want to consider an ADSR-type envelope generator as well, again depending upon your anticipated uses. I wouldn't hold your breath on the Bananalogue, although it's anyone's guess what will happen in the future.

okaaay..

what about something more like this?

notice i replaced my model 9 with the model 14 and the doepfer vc cf. . perhaps that is overkill for panning.. i feel a little obsessed with panning and i'm not even sure how much i will use it in practice. actually probably a lot since i use panning a lot in my music in general... hopefully doepfer will hurry it up with their new vc panning mixer.. but damn that thing looks huge in the prelim pics.. i don't need to be able to pan more than a couple of signals at a time probably.. i had the cwejman in my planner rack for a long time but i don't know if i can bring myself to pay $800 for a friggin mixer. </ramble>

i also threw out the mfb dual lfo which i feel a little unsure about.

i wouldn't kick this one out of bed. fo sho.

oh yeah.. and i have decided i'm going to have to build a box of multiples.. maybe 2x2 cube that just hangs in front of my modular.. lol. that would be wicked. a feedback cube! :headbang:

oh crap i just realized. i need a voltage inverter!!

Do you think you will really need both the Quad ADSR and the Quad AD/LFO?

I do not have the Makenoise LPG but I have the Plan B and I use my A-143-1 on it all the time. I will be getting a M-10 when they get back in stock however.

Bite the bullet and get the Cwejman MX-4s and a PH-4 if you are into heavy panning. Problem solved and you can put that baby to rest because I do not think it gets much better than that.

Cheers,
Rob

Analogue Solutions makes an inverter/mixer/multiple/buffer module, which handles a variety of needs at a small size and small price. Here's a link: http://www.noisebug.net/site/analogueso ... .cfm?id=21

Analogue Systems makes one too, although it's a larger and more expensive. However it would likely be better suited if you are hoping for something that just inverts the signal rather than multiplying or mixing it as well. It also has two separate inputs rather than one. Link: http://www.bigcitymusic.com/product.asp ... id=1000177

I also agree that if you are heavily into panning, you may want to just save up and go for the Cwejman MX-4s and PH-4 modules. That would solve a large amount of your mixing needs as well as cover essentially any panning desires you may have, not to mention the other unique capabilities that the PH-4 can give your system. While I do agree that it's a hefty piece of change for a mixer, if panning is something you're hoping for then it would be difficult to match the capabilities of the Cwejman without sacrificing space and ease of use.

Just FYI in case you haven't noticed the posts: I'm using 12u EWI cases and DIY PowerOne supplies for my MOTM synth. Here's a recent post about my revision to the power supply: viewtopic.php?t=2540

Here's an 'old' picture (from September :lol:) of the back of my first cabinet with the original version of my power supply and protection panels in place:

pure sex.

if you don't mind my asking.. where did you get that switched fused power entry module and how much did it cost?

everything i have seen as nice as that one seems to be into the $50 range or more.. or it's a snap in module.. . it's looking like i'm going to have to source the switch and the fuse separate from the power entry module to get my bang for the buck.. which is the whole point of this case.

Here is more info than you may have wanted! :hyper:

Below are three of the biggest sites to get DIY electronic parts:
http://www.alliedelec.com/
http://www.digikey.com/
http://www.mouser.com/

The only part of my power supply that came from Synth Tech is the MOTM-990 power distribution board: http://www.synthtech.com/testcart/index ... cts_id=182

The power supply module is made by Power-One and is model HBAA-40W-AG: http://www.power-one.com/cgi-bin/acdc_s ... &x=46&y=19

The power entry module is made by Qualtek and is part number 864-03/003: http://www.qualtekusa.com/catalog2/emi_ ... 403001.pdf Yes, it is one of the more expensive ones. Allied has it for $30.33 and Digikey has it for $34.97
There are like 15 and a half BILLION different variations on power entry modules! :jawdrop: Well, at least hundreds! :confused: If you look at Allied's main page for power inlets they show a 'Top seller' for $8.50 that looks like it should work. Make sure you Check out David Brewster's site http://pugix.com/synth/portable-rack-cabinets/ That page was the main inspiration for my cabinets and power supply! He mentions the power inlet he used " . . . combination AC inlet, power switch and fuse, Schurter IEC320 AC I, (Mouser 693-4304.6090) for $9.00"

The panel is a Raxxess 2U steel: http://www.raxxess.com/product.asp?ID=362 I’d recommend going with a flanged aluminum panel though because they are much easier to drill etc. I liked the Raxxess steel because the finish looks very similar to the MOTM panels. There is also a 1U Raxxess panel at the top of my racks.

The vent panels are Middle Atlantic model VT3: http://www.bswusa.com/proditem.asp?item=VT3 Broadcast Supply have really good prices and service.

The wire and crimp connectors came from Home Depot ;-)

And I just happened to get done taking this picture. It's all the parts needed to build a power supply like mine, not including solder, tools and elbow grease. It's almost like a kit! 8) :

Enjoy! :party:

!!!!!!!!!!!!! :love: :love: :sb: :sb: :love: :love: :hyper: :sb: :love: :hyper: :sb: !!!!!!!!!!!!!!!!!!!!!!!!!

you rule.

as you said there are about a katrillion power entry modules out there. this definitely helps me finalize my order with mouser and get my rack running!
