Open Sound Control developments

There's been a lot of work done with Madrona Labs’ instruments and OSC (Open Sound Control) lately. I’m not sure why the sudden flurry of developments—maybe winter is suited to working on these plumbing/scaffolding types of activities. In any case, I'm very happy to see it. Open Sound Control is much more suited than MIDI for handling the high-resolution, rich, per-touch data that comes from instruments like the Soundplane.

First, here are a couple of videos from António Machado, showing his work with a Haken Continuum, Kaivo, and Aalto. He uses the EigenD environment and an “agent” (EigenD object) written by Mark Harris to give high-res, note-per-touch data to Aalto and Kaivo. It’s rare to see a techy video that is this enjoyable to listen to in its own right, so a big thanks to António and Mark, and please enjoy...

Educational pricing

It’s educational

I’ve always been happy to offer educational pricing deals for my plugins, if someone asks. I have not generally advertised it because the selling mechanism was a bit of a pain to deal with for both me and the buyer. Thanks to some improvements to the web site, that is no longer the case, so I'm spreading the news more widely now.

A 50% discount on all Madrona Labs software is available for any person currently enrolled in or teaching school or university. If you would like to use this discount, please do the following:

  • Make a Madrona Labs account if you don’t have one
  • Send an email to support@madronalabs.com including a picture of your current student or faculty ID, and telling me what you want to buy (Aalto and/or Kaivo). Please keep the image size small (< 1Mb) or the mail may bounce!
When I get the email I’ll send you download coupons that you can use at purchase to get your educational discount.

I plan to keep this 50% discount on software available indefinitely, so there’s no hurry. Madrona Labs would not be here without the past support of my research by the University of Victoria, and its future will be shaped by ideas presented at conferences like DAFX and NIME.

For site license pricing, please contact me at support@madronalabs.com.


I’m only taking one class, is that OK?
Yes, thanks for asking.

My school or university doesn’t have IDs.
Then it’s probably not an accredited educational institution, which is kind of where I draw the line.

Is there a discount on hardware?

Is this educational version different in any way from the normal software?
No. It is the same license, for commercial or non-commercial use, and does not expire. It will qualify for the same upgrades as the full-priced version.

Can I use the educational discount along with another sale discount?
No, only one discount at once.

Soundplanes available!

I always try to refine the Soundplane design and production process, and I can say that the third run of Soundplanes has turned out to be the best one yet. I allowed for a 10% failure rate of finished main circuit boards, building 30 complete boards and only selling 27. Happily, we had a 0% failure rate and every board has tested OK. So, I have an extra instrument to offer right now and a couple more special builds waiting in the wings.

Soundplane #0073

Soundplane #0073

Here you see Soundplane #0073 (click for closeups). One of the darker-colored cherry instruments from the third run, it is a sharp looker, and of course a smooth player. It's for sale at $1,895—if you would like to order it, just send me an email to randy at madronalabs dot com and I'll send a money request to you via PayPal. I can ship it out immediately. Please see the ordering info at http://madronalabs.com/soundplane, especially if you are outside the USA.

There are also two instruments for sale on the forums. One is in the USA and essentially unused, from this most recent run. There is also an instrument from the previous run for sale by its owner in Europe. For a European buyer it could mean a good savings on the purchase prices as well as duties and postage.

Run 3 done, Aalto work, Yosemite

Run 3 of Soundplanes is all wrapped up, and for a couple of weeks most of the instruments have been in happy new hands. Some people weren’t available to receive them, so here are a couple of stragglers going out this week.


After this run, I find myself with two or three remaining sets of good parts, as well as some prototype cases I had milled from walnut. I look forward to building out these instruments when I have time to get back into the shop, so watch this space for info if you're looking for a Soundplane because I plan to put one or more them up for sale if they make the cut.

Right now, though, I am on a dive back into Aalto land, and I'm not coming out until the 1.6 version is ready. This will fix the bug with the preset converter in version 1.5, as well as many other issues. This won't be a "fancy new features" release, rather the result of a whole lot of work under the hood that should make everything more solid and efficient. You know, the kind of release you wish companies would devote more time to.

Apple just released a new version of MacOS called Yosemite. I haven't tried it yet because of the aforementioned Aalto work. I have heard a few rumblings about problems with window management in VST plugins. So for now, I would recommend that you not upgrade, unless you can't resist all the nice new eye candy, and you're not in the middle of a project. If you do try it out, please drop by the forums and let us all know how it's going.

Mise en place

Here’s a new run 3 Soundplane on the bench, with the little boxes of parts and some of the tools I need to put it together:

surfaces 1-8

The little boxes are a low-tech solution that has evolved over a few generations. The weighted bases let me grab parts out of them quickly without tipping them over very often. Sometimes it's the little things.

Here’s the grain on our new friend, up close. It’s performing wonderfully. My pictures never do justice to the shell inlays, which in real life are iridescent.

Soundplane production 2

Our third run of Soundplanes is looking good. Here are all 30 enclosures after three coats of oil finish.

There is some particularly nice variety in this batch of cherry.

Cutting the veneer is a fun part of the process, where I get to decide what part of the crazy abstract walnut grain landscape to turn into each playing surface. This is done now, and the sandwich of materials that forms each Soundplane surface is ready to be laser-cut by our friends at Gurian Instruments here in Seattle.

You might wonder why Madrona Labs doesn't have a laser cutter, since they are such fun tools. The kind of laser cutter that can do the needed cuts through the surfaces is a big, expensive, and sometimes tempermental beast. To do that work with precision takes a lot of practice and I'm happy to have it done by experts.

Soundplane production

Soundplane production is in full swing here, and a busy month is planned so we can start shipping in early August. Here's Christopher tapping the walnut eyes into some Soundplanes:

Here are some of the new cherry enclosures with eyes awaiting final sanding and finishing. The wood has milled just great and is very smooth and dimensionally stable. I like the figure in the cherry very much, there are some nice waves and topographies going on and I’m excited to see how they pop when we put the finish on. Part of the charm of cherry is that it takes on a darker patina over time with light exposure and handling.

Thanks to my friends Alex and Erika we are the proud caretakers of a Shopsmith Mark V. I remember these being advertised on late-night TV long ago. Sort of a giant multi-tool with saw, drill press, lathe and boring capabilities. Turns out it's actually a good sturdy tool, much nicer than my loud old contractors' saw. It transforms into various configurations including a lathe, but I will probably leave it set up as a table saw most of the time.

And that's the news from the shop. The next couple of weeks are all about sanding and finishing the enclosures, then we can start in on the surfaces.

It's the Kaivo 1.1 update!

Hi there! For the past three months, I've been working on an update to Kaivo, and it's finally time to roll it out. I've tuned up the audio engine, improved the graphics and spent many hours finding and fixing a whole host of minor UI issues that made people including me go "grrrr" sometimes. Thanks as always for your support, and all the feedback you have sent my way about the 1.0 version. This 1.1 release is feeling buttery smooth here, and I hope it gives you many happy hours diving into sound.


  • over 50 new factory patches
  • optimized DSP code (10-20% improvement)
  • made demo reminder noise much quieter
  • added a new audio import dialog
  • trimmed and optimized source samples
  • fixed a compatibility problem with Soundplane
  • improved model sonics in high frequencies
  • improved resonator tuning
  • increased range of resonator damping parameter
  • improved legibility of scope dials
  • fixed a problem saving the window location
  • fixed glitches in xy scope display
  • improved typography
  • improved granulator view speed
  • fixed incredibly annoying disappearing menu issue
  • fixed keyboard stealing issue in 64-bit VST
  • added case-insensitive sort for patch menu
  • fixed audio issues with body nonlinearity
  • and many more minor fixes.

Special thanks for making this release happen go to Don Solaris, who generously contributed some great factory patches. (If you happen to have a Waldorf Blofeld, check out his excellent "Analog Voltage" patches at the Waldorf website.) The new Import dialog is not reflected in the manual yet. But it should be pretty straightforward. In the future, I want to add some file combining magic here, but for now, it simply lets you pull up a file, listen to it, and it the file is longer than 8 seconds, pick the 8 second clip you want to import into Kaivo. If you have any questions, please stop into the forums and ask.
