RK3 and RK4

[electricanada]

Back with a couple more demos, showing its use as a waveshaper. These are both taken from unfinished songs on my hard drive. The first one is just the track soloed, and the second one also includes another bass part and percussion. No reason why; just felt like doing it that way.

Triangle Wave through VCA into R53
This is a sample from a track of a song that's mostly finished. The patch is very simple: just a triangle wave into a VCA with a slow decay, being fed into the R53 audio input. The pulser is tuned to a point just before the high end of self-oscillation, and I think the Ringmod Carrier Input Level knob is at about 4:30. I would really recommend looking at this through a scope if you can, to get a better idea of what it's doing.

R55>RK6>R53 (plus other tracks)
This example uses the pulser tuned to the low range before self-oscillation, once again using the Ringmod Carrier Input Level knob to tune in the spikiness. Instead of gating the oscillator with a VCA, this time it's being gated by an RK3 set to just a little bit of resonance. Some nice, septic wubby sounds here.


I've always wondered why the manuals make no mention of the fact that the Carrier Input knobs affect the pulser quality even when nothing is plugged into the Carrier In. To me it's a really important feature of controlling the module, and I wonder how many people simply don't know that it does something like that. I've also wondered what exactly it's doing, since so far I haven't been able to replicate it through patching.

I checked my disc for recordings since I got the RK3 and there's only really one where the RK3 is prominent:

A sequence from the Make Noise 0-coast was fed into the RK3 for grit and then passed through the R56 for heavy reverb. After a while I pushed forth the dry signal and added a beat.

Note that it's an untreated patch recording so it doesn't sound great but it gives a sense of the grit that RK3 can add.

Doesn't work for me. It says that there is no such track.

Triangle Wave through VCA into R53

Very nice! Sounds both nice and cool.

Cool stuff Adds some nice grit

Rad sounds man!

Try it one more time. It's working for me on my work computer now. If it breaks again, I give up.

Worked just now—my life is complete!

Another very much unfinished track. First you hear a rather clean sawtooth arpeggio through the R56. Then the RK3 adds a different tone to it (making the whole patch rather dissonant when the bassline comes in.. but what the hey).

you do great work and should be more famous....

Thanks! You are way too kind but I’ll takes it as I gets it.

Very amusing to me that I’ve shunned Metasonix gear for many years (long before I got into eurorack) and it turns out that I was wrong in my assumptions all along. It has loads of (deranged) personality but can sound cordial too. That range makes it really interesting and pleasing to work with.

Made some softcore industrial ambient by sending the SSF Entity Percussion and the ALM MCO to the RK3 and patching the result through XAOC Belgrad to the R56. LOads of RK3 character in this short outtake:

I'm extremely intrigued by the RK3. I've been reading through this thread and am noticing that some people are having issues with the power draw taxing their power source too much on startup. I am currently using the power system by Trogotronic.

I have never had a single issue to date, but am wondering if anybody here has used Metasonix modules with Trogotronic power systems, and if they have ever run into any problems?

Trogotronic's m/15 supply is excellent and will power numerous Metasonix or Trogotronic tube modules. Trogotronic also makes great cabinets with massive power supplies built in. Recommended.

You'll be fine. The people who report problems are generally using cheap switching supplies like the Tiptop μZeus.

I really like this.

looking to pick up a rk3 - anyone have good experiences with these in a tiptop mantis? should be well under the 3A/1000mA for +12v at startup, but i’m slightly cautious at how the power is distributed to the ‘zones’. thanks!

A Mantis supply should be okay. Just don't try to use an old Happy Ending or early uZeus supply to run it.

on the webpage there is a very detailed description what you should use and what not...

I want to use an RK4 or maybe an RK7 in a small skiff. Will a new uZeus with a 3000mA uZeus Boost/Mantis Universal Power Adapter power an RK4 with no other modules connected? If not, would a Row 40 do it, again, with no other modules connected?

maybe and probably not

Hi,

Very happy RK3 owner here. But wondering, is it normal for it to have a very apparent high frequency whine that increases with the output level? Maybe it's because I have it in the top row of a Pittsburgh Modular 420 case and its right in front of one of those power transformer coil looking things? (the top row has the least amount of space from the back to the front so it's basically as close as it can possibly be to the power supply stuff.
