I based my panel legends on the rendering at the Magic Smoke site. So my outputs are:
0˚/12dB, 90˚/24 dB, 180˚/-24˚ dB, & 270˚/-12 dB. This doesn't jive with what your showing above  . My panel has been etched and is a done deal. Do I need to consider a second go at it?
thanks
Peter

Subject description: WHAT?? where is my trimmer?!? |
|
|
Assembled the Mankato PCB last night, found that I was shorted my 500 ohm trimmers for the V/Oct. While I am anxious and cant wait for the replacement to show up, which is my best temporary alternative, keeping in mind that the scaling is not of deadly importance right away.
1. Cobble a resistor somewhere around 250 ohms and toss it in for now.
2. Use a 1K multi turn and dial it down to the first 5 turns.
3. If I am just being an idjut, feel free to toss your rotten tomatoes on 3...2...1...
Thanks!! |

Hey Number,
Actually, I'd recommend changing R42d to 200k and the v/oct trimmer (R43) to a 1k. Makes setting the response easier (this change is in the Rev03 parts list). Also, don't forget to check across a range of frequencies when adjusting the Resonance trim. Set the trimmer too high and the sine from the 6dB output will distort; set it too low and the Mankato will stop oscillating at lower frequencies. Luckily, the "middle ground" is pretty easy to find. Hope this helps!

Hey Peter,
Unfortunately, the render on the Magic Smoke site is very old and doesn't have the output phases right. I really feel bad about that. What you want is
0° / -12dB
90° / -24dB
180° / 12dB
270° / 24dB
I'll see if I can re-render that image and have John update the image. Sorry about that.

Hey Solder,
It'll be on it's way to you by this weekend. Just got them in, so we're checking them and packing them up to go winging their way around the world!

just finished wiring up my mankato. powered it up on the workbench and: hey, what a nice creature has come to live? love on the very first sight.
thank you thomas, thank you tim. great work.
i hooked it up to the PS3100 resonators and i think this is what they have waited for!
i then tried the audiorange. mixed different outputs and was surprised by the different timbres. will have to check them on the scope these days.
finally used the mankato as a filter for the sn voice modulated by the baby10 seq and that even sounded very nice, due to the range, and due to the nice sounding resonance, i guess.
3in1  and i am happy...

my eurorack front panel (schaeffer) will arrive this week.
i decided to have all outputs and omitted some of the inputs...

| Tim Servo wrote: | Hi All,
I know this subject has come up a few times, but we have a new source for face panels and so I'm trying to gauge how many people will be interested. Initially, I'm thinking of getting a 4.5" wide Frac panel made for the "Full Boat" 8-output Mankato. These will be .093" anodized black aluminum with white silkscreen lettering and will go for about $30. We may offer a discount for pre-orders (lead time about 4 weeks), but we're still pondering that. Maybe depends on if enough people really want one. I've attached a low-res version of the artwork so you can get an idea what is on the panel. We're also working on a PCB mount bracket that attaches to the face panel. This will be a "universal" bracket that could be used with any 4.5" Frac panel. It should be about $10, but I don't have a firm price on that one yet.
So... anyone interested? |
my $.02 on the layout: much as i like having controls visually associated to their jacks, i'd much prefer to move the inputs down below the controls... otherwise the patchcords interfer with the knobs. also, what' that little hash-thingy above the coarse control? looks like a leftover section of a serge swoosh.
all that said, i would probably buy at least one. yay frac!

Hey BBob (and others),
I kind of see your reasoning for wanting the patch points at the bottom of a module, but once you have more than one row of modules, the cords drape over the modules below anyway. I was thinking of making up something that would go between module rows and act a little like the "finger" racks that many labs use to store test leads. The rack would keep the cords from draping below, and even allow you to keep cords at the top of a module from draping over the module (by wrapping the cords over the rack above). Kinda hard to explain...
ANYway, so I've been thinking of alternate layouts. I love the layout that STG Sound Labs has done (I'll have some of those to show at the AH Cali show and I'll probably end up getting one for myself), but I'm trying to come up with a "Magic Smoke" style that will also be consistent across several different module types. To that end, I present the first annual MSE Mankato Beauty Pageant.  The attached pic shows three different layouts. Starting at the left, the first is the present ARP-inspired layout. I really like this one, even with the patchcord drape problem. It's pretty easy to understand, it's logical (at least to me) and it is very easy to make it consistent across different types of modules.
The layout to the far right is copied from our own Etaoin. It's a nice, compact layout, and the grouping is very clean and consistent. The "jack field" is a little crowded, but this shouldn't be a problem in most cases (very rarely would you use all eight outs and the inputs simulataneously). I like this one too, but I think this one isn't as easy to adapt to other modules.
In the middle we have sort of a "hybrid" approach. The love child of the far left and the far right (it should run for Congress, but that's another story). This one appeals to me in that it more consistently groups the jacks and the associated attenuators / modifiers. The outputs are kept away from the audio and FM inputs, and having the outputs on the right edge cuts down on (practically eliminates) the patchcord drape problem. I think this layout can be fairly easily adapted to other types of modules, and I also think it looks good. Almost has a Moog-ish look to it. Sort of.
Of course, the finished panels would be black anodized with white silkscreen legends.
And the judges say... ?
Oh, and the "swoosh" mark is a racing stripe. It makes the Mankato go faster (adds about 25MPH to the top end). Seriously? Okay, Fonink is right, it roughly indicates the Audio Range.
Thanks as always for everybody's feedback!

i _did_ try to incorporate that in my layout, however when i implemented it the already busy coarse tuning region on my highly-literal layout became a complete mess.
i do think it's a good idea though, and i'm glad you worked it into your layouts. |

i like the addition of the ac/dc swithches on the new layouts.
a big plus of the right-most design is the additional room between pots. blacet is able to space his pots very tight vertically, because there's plenty of room to the sides, so you can still get your fingers in there.
only downside is the one 1v/oct input jack that is visually associated w/ the outputs... but as they say "consistancy is the hobgobblin of small minds" (my own included)...
thanks for playing around with these...

Hey C,
Your board (and six tempcos) have shipped and should be to you sometime this week or early next. Monday is a holiday in the US, so that may slow things a teeny bit, but you should be getting your stuff soon! Thanks!

Hey Bbob,
Nice work! However, I've got the original BOM as an Excel spreadsheet and I'll post that here if anybody still needs it. From that, you'll be able to extract whatever info you need. Interest?
