holy crap i've got one on the way :shock:


ok, i gotta admit i'm more excited about this than anything in a while

can any of you guys give me some ideas on cool things to do with a quadrature sine oscillator? i've got some ideas for modulating pairs of things with them, and obviously will try every FM routing I can think of, but i know there's a whole school of phased sine wave ideas that i'm clueless about. help a brother out ;)

Wow. The thought of using that for FM sounds amazing. I really have no idea what sounds would result from QAM (which is what I'm assuming that module's all about), but I can't wait to hear.

you can create sheppard tones with it i believe...it's like an audio version of the "barber pole effect", a pitch continually ascending or descending...just looking at that picture, if you can send a slow ramp up sawtooth CV and it will give 0, 90, 180, 270 degs out to 4 different oscs set the same, you should get something along those lines...or 4 phase shifters, etc...i don't know anything about that mod, but that's my guess...i've made sheppard tones with a test sweep tone off a cd (made lots of copies and edits in a DAW), and it's a cool effect...

awesome, thanks guys! Ross, you're totally right, I didn't even think of using it as a sheppard generator, hmm, I think that's going to be a lot of fun

very, very excited about this module!!

with the amount of mods you have, and what looks like 8 phase outputs, you can go waaaay past sheppard tones....

woah....how did i not know about this nord modular book?? :shock:

what an awesome resource, thanks Steve 8)

this is amazing. Man, I love having a big modular system so much. I'll be able to do some pretty big versions of that patch - i have 4 vcos, the 8-phase sine oscillator, a pair of precise 'proper' ring modulators (CGSRR), and a bunch of phase-shifting AP filters, and a bunch of env followers.

I think having the mankato is going to push me into doing a whole realm of new things with my system. just looking at that page on the nordbook makes me think this is HUGE.

I think STG is considering an expander that would add all the necessary elements for frequency shifting. I'm thinking of making some room in my Dotcom for this one. I love that all the functions range from subsonic to ultrasonic. That fits my technique perfectly. How much does the Frac version cost?

it's supposed to be for sale at analoguehaven.com but i didn't see it listed under the other few STG modules they have for sale.

where'd you order yours Muff?

I completely agree!!! And by 'all functions', as you probably know, this includes self-oscillation. It'll oscillate even in very slow/low settings. Now that is cool! STG tells me it makes a very interesting LFO, in addition to a 8-phase oscillator, 4-pole VCF, VC Slew Processor etc etc etc

Very exciting.

That expander sounds amazing. I'm gonna petition him to do it. That would be fantastic and would make me feel 110% better about missing that Encore Freq. Shifter on eBay last week.

I think Shawn @ AH knew I was really horny for this - he emailed me yesterday saying they had just received them - that's where mine is coming from. I don't think they've had time to update the webpage yet, but they are in. AH's price is $395

Shawn just emailed me to say that the page at AH for the Mankato is now up.

Hmm, I think Shawn lurks on this forum but doesn't register and post.

DAMN YOU LURKERS!! POST DAMN YOU!! :P


Cool stuff, thanks Shawn. He also told me that I ordered the very first one 8)

Holy fuc* I love the look of that module.
I agree-- perhaps the coolest-looking frac module I've yet seen.

props to the Guy for this really nice looking build and the circular design.
so whats the big honkin knob in the middle for?
muff--im very interested in hearing you hook up all 8 outputs and modulating stuff!

the big knob in the middle is the coarse frequency control. the 'vernier' knob is the fine frequency control.

The pair are needed because the range of the filter is ENORMOUS. The audible range is only about 70 degrees of the big knob's travel, the rest is dedicated to sub-audio and super-audio. So if you want to actually tune to pitch within those 70-degrees of audible spectrum, you really do (apparently) need the fine and course knobs.

The 'look' of the unit would at first lead one to believe that the knob is a big crossfader between the different filter slopes shown in the circle of jacks - at least that was my first thought. But they have little to do with each other, except for the fact that they look totally bloody cool arranged like that 8)

by the way i put up a blog post with a bit more info about this

Here's 7 minutes of a Mankato being modulated and tweaked. It's long and noisey.

http://www.twango.com/media/Squibbons.p ... bons.10003

Blacet VCO sawtooth outputs to a Mankato filter. The filter is modulated by two lfos and then outputs 4 non-inverted phase shifted outs to a mixer. At 4:55 til the end, the VCO is removed and the filter is set to full regneration. All sounds from this point are purely from the Mankato being modulated by the lfos.

Oh, and I posted this in the thread about my systems, but this is the Mankato and JAG goofing around with each other:

Damn, I need one of those. Luckily for my finances, the Dotcom version is delayed by the need for a custom circuit board. Thanks for the FM demo. It does great FM like I thought it would.

First off... Muffypoo... how come you dont think you will get yours? If it's because of getting ahold of shawn.. it's because he's moving. He's helping me out with a transaction and usually he gets back to me RIGHT AWAY. But I emailed him last monday and I'm still waiting to hear from him. I just emailed the main email addy... we'll see. I'm sure all is cool tho brutha.

So... this motherfucker looks/sounds AWESOME. I was thinking about the Encore Frequency Shifter though as well.... bitch of a decision eh? lol. I just loved this clip of the encore, however... it has been modified.

could be - hopefully

it's just very unlike him - and he emailed me to ask if I've received it, I replied asking if he would trace the shipment - didn't hear anything back, and repeated the same request on wednesday - still nothing, and no Mankato has arrived. Very very odd. I hope Shawn is OK.

Yeah... I called on thursday and talked to a guy at AH saying "look man... I need to follow up on this order and shawn hasnt gotten back to me in almost a week... just seeing what's going on" and he said that he was moving and was really busy. *shrugs* It's unlike shawn by far. That guy will email me at 4am np usually.

Kind of strange that its taken that long to receive the shipment. That's why... I have them do USPS. 2day priority and it's cheaper. lol. Only bitch is you cant track it but... atleast in 2 or 3 days you know that something wrong.

That filter sounds/looks fucking sick...... just cant decide what I want to spend my 560 bucks on i have in the bank. lol.

Either.... save it and wait for the AFG..... buy the last harvestman zorlon cannon ah has for $300 and then put the rest towards a moog mf-107.... or buy a couple of the other livewire modules... or... Cyndustries Saw Animator...

Gear porn, gotta love it. i want it all... just a matter of what first. lol

Also cant decide between that mankato and the encore frequency shifter. They both sound outerworldy.

not a "need" as much as an "ought to" at the time, and as it goes on i feel more like it's a "desire" and not a "necessity." voltage control of regeneration is a "nifty" feature, but IMHO the "nifty" feature of the mank is 8 different outputs.

also, it's quite the polite filter. it's not "aggro", according to some people. i personally view this as a positive attribute.

it does get pretty nuts when you're using the 6 dB output at high regenerations, which is just the weirdest filter i've ever heard (it's kind of like a Polivoks dressed up to go to church, if that makes sense.)

and because it's so polite, i figure you might want to use a distortion module or a wave folder / multiplier for regeneration anyway to really freak it up a little. that would also allow you to choose _which_ pole you were tapping off for regeneration. since it's got neg outputs of every poll, you can use a simple VCA (under normal circumstances you'd need a VCA with inverting outputs and a mult. these two things are taken care of for you here with all the different outputs.)

not only do the multiple outputs help you set up VC regeneration, it's got 3 inputs. that's plenty to do all sorts of weirdness with putting a flanger or suboctave processor or pitch shifter in the feedback path of the filter without involving any other modules like mixers or inverters.

bottom line is i'm going to go ahead with the Mankato - MU Edition using the existing board, at least for a while. if anyone has a religious opposition to this please email me.

despite this decision, it's still behind the Wave Folder as far as release goes, and that has to wait until my wheelchair-bound ass can get to the post office, which is looking like tomorrow or thursday.

there are a few prerelease Wave Folders (the people who specifically requested the module and a person who traded an oscillator for one in response to my offer to the Synthesizers.com list) in this pile:

i guess i could get a trailer for the wheelchair.
