This is fixed in the new installer. If you are still having issues with Kaivo's body module not working properly, try downloading the 1.3.1 installer again. The file name will be
KaivoInstaller1.3.1.exe (no .zip).

Aalto on Linnstrument, via MPE

And apparently the MPE implementation works! Thanks for sharing, Roger.

With Aalto 1.7, aftertouch is implemented in an MPE-compatible way—all of the factory Aalto patches will play expressively with Soundplane, LinnStrument, and other MPE-aware controllers over MIDI. And adding pressure, x or y control to any of your existing Aalto patches is just a virtual patch cable away. I’m excited to see more of the fruits of this cooperation.

Hi, Kaivo 1.3.1 is online now and has the convert presets menu option. In 1.2 it's in the same place, in the main patch menu.

Please note if the presets have been moved to the new location you will need to move them back to ~/Library/Audio/Plug-Ins/Presets/Madrona Labs/Kaivo to get the preset converter to see them. I have heard one report that the old presets somehow made it to the new location without getting converted. I'm not sure what went on there, so if that happened to you, sorry for the inconvenience.

Thanks for sharing your work! I've got no Ultranova here but it is more tempting now!

@hyperscientist thanks again for jumping back in. I'm glad things are better. You may have seen in the "Retina MBP glitches" thread: I'm getting a MBP 12,1 this week so I expect things will improve more on this machine soon!

oh derp, it looks like something went wrong with the installer—i'll take care of this in the morning.

Tue, Jan 03, 2017, 12:27

Fixed, thanks!

I have the "convert presets" option restored in Kaivo 1.3 now and will be releasing it shortly.

The second one is pretty different ! :-)

So... MIDI and MIDI MPE will indeed produce really different signals out of the KEY module, which in turn will make really different sounds. You can see that the mod outputs change their labels, because they turn from mod cc outputs into dedicated x and y outputs for MPE. So now the x and y information is going to the patch and it sounds completely different as a result.

You can consider the MIDI / MPE choice as a fundamental part of the patch that you probably won't change afterwards. Then you can work by either making MPE patches from the ground up, or switching a MIDI patch to MPE and then adding the modulation you want.

The same is true with OSC and the Soundplane inputs by the way. To get all the Soundplane data in the KEY module outputs are repurposed and so in general patches won't be compatible.

Nice playing BTW, I am interested to hear what you do with Linnstrument down the road.

OK, I just ordered a refurbished 13" RMBP Early 2015 from Apple. I can pick it up in a few days and hopefully reproduce this then.

STICKY: Kaivo patch thread

A place for Kaivo patches! Just select copy to clipboard from the patch menu, and paste here to share.

I bet it's just that mod cc # is defaulting to 2. If you change it to 1 it should work. Not sure how a default of 2 got in there so I'll change that.

Mon, Jan 02, 2017, 10:11

So i just went to test this and I can't reproduce. Kaivo 1.3.0 ( and 1.3.1 ) are responding to mod wheel OK, both from automation and external controller in Live.

The "mod cc" control in the INPUT module needs to be 1. At that setting you should see the mod light flash in the INPUT module when the modwheel goes from 0 to 127.

Can you think of anything else I should try to reproduce this?

Mon, Jan 02, 2017, 09:47

Weird. thanks for the report. One more quick fix to sneak into this update release coming very soon

Sat, Dec 31, 2016, 14:12

I can't test it on the affected machines, so I'm not too hopeful. But if my hunch is right, this beta may make things better. http://madronalabs.com/media/aalto/Aalto1.8.1b2.pkg

If you want to play a different voice from each note of the Linnstrument, you want MIDI MPE. This can certainly sound different from using MIDI alone. It's hard for me to guess what you might mean by "completely different" though or whether it is a problem. In general I would advise to focus on MPE with your Linnstrument and I'll be here to help.

There's not much if anything in the manual on MPE yet. Sorry it's lagging behind reality. I'll do what I can to catch up soon.

Happy new year!

Sat, Dec 31, 2016, 10:36

OK, thanks for the report. I'll see what I can do to reproduce this.

Virta at 96k is going to be a beast, but I'm going to make it better over time.

HI Roland, good to hear from you! So, probably what happened is you made presets in version 1.1 and then didn't do "convert presets" with version 1.2. I should have made a better effort to let people know this was needed. To fix it:

  • make sure your old presets (the ones not working) are in the old location of ~/Library/Audio/Plug-Ins/Presets/Madrona Labs/Kaivo
  • install Kaivo v. 1.2 (you may have to manually delete 1.3.0 first)
  • open up a Kaivo and choose "convert presets" from the main menu

This will copy the presets from the old location to the new location in ~/Music/Madrona Labs while converting them from XML to JSON.

If you have any troubles you can let me know here or by email to (support at madronalabs.com) and I'll be around to help.

Hi, I appreciate the feedback. Can you tell me what CPU you have in your MacBook Pro?

Tue, Dec 27, 2016, 10:43

The Soundplane antennas are not available. If you're making one controller it's not too hard to make a copper foil one yourself. you will probably want to cut slits in them so they are a little flexible.

I advise everyone to start with a single-point sensor to test your technology and materials.

Tue, Dec 27, 2016, 10:40

sure, just send it some notes with different velocities! Or am I missing your point?

Tue, Dec 27, 2016, 10:38

I love self-running patches! Thanks so much for sharing with the greater Aaltosphere. Please keep in touch, I'm interested to hear what finished music comes out of your process.

Tue, Dec 27, 2016, 10:37

Is there a crash report or any other information you can send me? What exactly happens when Reaper crashes? Are you trying to do any particular actions beforehand? Thanks.

Beta fixes available for all plugins

These betas should fix a few problems that came up with the latest releases:

  • Fixed Kaivo patcher to body connection problems
  • Fixed missing runtime causing failure on some Windows machines
  • Fixed silent Virta delay on Windows
  • Fixed a pitch tracking problem on Virta for Windows



As betas, these have not been extensively tested, but they seem to work so far. If you have had troubles with the recent releases, please try these and let me know how it goes.

These betas do work with the new licensing system, as indeed all future ones will. So if you have a license and the plugin is working for you, you may keep using it without any demo restrictions.

I'm very happy to have turned these fixes around quickly thanks to the new build scripts and licensing code in the new versions. In general, you can expect to get fixes from me more rapidly and more often because of this. And I'll have more time to work on other neat stuff too.

I just download Reaper to my Windows 10 machine and it's working here. I added some missing Microsoft runtime files in a 1.8.1 update coming soon. That may fix it for you. Please let me know.

Fri, Dec 23, 2016, 10:23

I'm happy to help. There are three steps:

  • download the new version
  • log in and get your license key from the "My licenses" page
  • click to paste the key into the plugin

If something is not working you can reply here or email me at support at madronalabs.com.

Confirmed for both Mac and Windows. will get a fix out ASAP.

Thu, Dec 22, 2016, 09:08

OK, Let's focus on Aalto then. the other plugs take a lot of CPU even when they are functioning properly, so the problem will be much more obvious with Aalto. It looks like one voice of Virta is taking up 25% of CPU or something in your example, which is too much. But 10% or so would not be out of line.

For more background on CPU use in the plugins please see http://madronalabs.com/topics/3565-getting-the-most-out-of-kaivo
You may find some tips that help. They are expected to take up significant CPU when no notes are playing, for example.

back to Aalto, here's a question: when you load Aalto does the CPU meter seem to go up gradually?

Thanks for the assistance. if you are willing to hang around and try some of my experiments I'll be happy to give you a coupon in appreciation.

Thu, Dec 22, 2016, 08:54

Thanks for the report, I'll take a look at this today.
