Okay, I updated my monotribe and DIY'd a CV/gate sending cable, and here's how it sounds:

[s]http://soundcloud.com/radiokoala/monotribe-fun-times[/s]

Sputnik DWG as a modulator. Osc1 sends CV/pitch information, and Osc2 gates the envelopes. In other words, it is frequency modulation by Osc1 since voltage is continuous, and it makes it sound more interesting than sending note values. Some cross-modulation between two oscillators as well.

For receiving CV I used Hz/V mode, and for gate an inverted trigger mode, because in usual mode I had no luck triggering the gates with a VCO. (Even though with square waveforms not in CV/gate mode it worked!)

Oh, and almost forgot: yes there is delay/reverb, for added liveliness, but it is an output of a monotribe only, nothing else. (No VCO to audio in or anything...)

Regarding the patch itself, overall it looked something like that:



Enjoy.

w00t

nice sounds thumbs up
old/original korg gate was 'switching', like moog: at 0V the env starts. modern/normal gate in expects 5V. so it seems your clock-osc does a nice 0V but not 5V Mr. Green you could check with a voltmeter ...
if you are into diy it would be easy to make some cmos osc. those can go up to 10V if you like hyper

Thanks!

They all do nice 0V, it's a lesser of all efforts to generate a 0V voltage hihi But really I think it's +5V/-5V, or what voltage VCOs usually have. No malfunction, that's for sure, but out of interest I will check it when there's a tester around.

BTW, just a few minutes ago uploaded a vid (continuing my CV/gate explorations thumbs up)

never assume anything. not in euroland Mr. Green who talked about 'assumption being the mother of all fuck-ups'? often it's 5Vpp, so -2,5V-+2,5V ... sometimes more, sometimes less hmmm..... seriously, i just don't get it
and you 'd be surprised how difficult it can be to get 0,000V. it's called 'offset' and not a welcome guest to amplifier-parties Mr. Green
you should def check:
-george duke live on stage with frank zappa using his arp odyssey's s&h to accompany/drive the 'idiot dancing contest'.
-brad pitt in '12 monkeys' (movie by director terry gilliam).
lol

haha! made me laugh Mr. Green

'idiot dancing contest' sound like fun, and by the way I have a Zappa t-shirt (lumpy gravy)...as for voltages, I sure will check them, now I'm curious myself. razz

hey radiokoala,
can you explain a little what exactly did you do in order to be able to send in cv/gate signals?
did you have to modify the monotribe or is it some new firmware feature?

It's a new firmware update. No mods needed.

is that the 2.0 firmware update? what possibilities does it give exactly? couldn't find anything on the korg site...

It's OS 2.11 but it's only on the Japanese version of Korg's website so far (probably hasn't been translated yet) :

http://www.korg.co.jp/Product/Dance/monotribe/version2.html
http://www.korg.co.jp/Support/Download/Update/monotribe/

You basically get CV/Gate input using a stereo minijack in the Trig In input.

Edit : I think it's actually a 4 poles mini jack that is needed

Yes, correct, a 4-pole mini jack. I DIY'ed my own, it's two mono patchcords on one side and a single plug on the other that is inserted in the monotribe.

When you download a firmware, despite manual is in japanese, inside pdf there is a pinout. Tip is for gate, ring 2 CV, sleeve is ground. Ring 1 is not used, but I have a madman idea that maybe in the future they will add a filter CV?! MY ASS IS BLEEDING

Regarding the possibilities of new firmware, in 2.0 there is a plenty (sample&hold, 16 steps for synth...etc), and 2.11 only adds CV/gate mode.

Oh, and last: update procedure is identical to 2.0, just read it in a guide that comes with 2.0 (it's in English). To enable CV, after updating you need to power on monotribe holding SN and GATE. Then press step 1, it turns on CV/gate mode. Last, to save settings press REC. Switching between Hz/V and V/Oct mode is step 2, and trigger/inverted trigger response is selected by a step 3. That's pretty much it. thumbs up

wonderful!
of course a standard camcorder has the CV ring wired to ground so those cannot be easily used... puh... still i am so impressed by KORG for doign this!
in fact, i suspect that they did not come out internationally with this yet because the next update should (hopefully) feature a CV/GATE OUT functionality (coordinated with the release of the new ms20 of course ...)

grin

either way, GOOD NEWS!

I've just thrown together the appropriate cable and performed the update, and there's a couple of minor changes you need to make to radiokoala's process to get this to work with standard Eurorack kit.

Assuming you've successfully installed the Monotribe v2.11 update, go into the appropriate setup mode as radiokoala describes by turning on whilst pressing SN and GATE.
You need to make sure that step 1 is lit to enter CV/GATE mode.

This is when things need to be a little different....
Set step 2 and 3 to be UNLIT, which selects V/OCT and the appropriate gate mode for Eurorack (i.e. high gate = note on).

You finally need to calibrate the Monotribe to your input. Easiest way is to use a MIDI module in your rack, so you know exactly what you're feeding in....

Set the VCO Octave on the Monotribe to 16' (I can't tell if you need to do this now, but as it is recommended for when you are doing CV/GATE playback, you may as well do it here just in case).

Select KEY or NARROW range on the Monotribe.

Play note C4 on your keyboard, ensuring your new cable is plugged into the Monotribe (i.e. CV & GATE are both being sent). Whilst holding that note, press PLAY. The LED on the PLAY button will light for around a second then fade out.
Next, play note C5 on your keyboard, and again, whilst holding that note, press PLAY on the Monotribe and wait a second for the LED to fade out.

At this point, you have successfully calibrated the Monotribe, perfectly aligned with an exact 1V/Oct range, and effectively tuned to your system (assuming standard tuning ;-).

Press REC to save the settings, and you're ready to go.

Hope that helps!

One final thing to note is that the MT doesn't appear to be able to respond to any form of envelope, but is limited to it's own three internal envelope shapes, with the second and third picking up a sustain stage in line with the gate length you send. The first envelope has it's own decay, but that cuts off abruptly when the gate closes. Still, better than nothing!

Of course, as an addendum to the above, that all only applies if you want a "vanilla" approach to controlling your Monotribe. If you want to be somewhat crazier with your sounds, the videos radiokoala is churning out have some great approaches in them!

thumbs up Thank you!

You know what else I'm thinking -- if sometime cv/gate out will be added, then you could also have a vanilla chromatic quantizer in the face of monotribe smile In KEY mode I believe any incoming voltage is quantized to the nearest semitone.

But that's not everything - you could also use monotribe to transpose your sequences! So you could send the same CV to a VCO and to another VCO thru monotribe, where you will use octave selector and transpose the incoming stuff octave up/down, or more. If you have a spare VCO, you could give it some sub-oscillator credentials for example This is fun! That's very nice, there's not even many modules (quantimator comes to mind) that allow you transposing stuff...

As you see, I still have some ideas, alright hihi

Hehe!

The quantising idea got me thinking that as the facility is there to calibrate the MT, you could force some further transposition which isn't full-octave focussed by calibrating at something other than C4-C5.

In other words, you can set the 1V/OCT scale to be whatever you like by just substituting C4-C5 calibration to be whatever you'd like 1V to represent, based at whatever note you desire.
