thanks and welcome!

Sorry you're having trouble. Can you try the samples and patches installer available on the product page? http://madronalabs.com/products/kaivo

Mon, Aug 01, 2016, 11:31

Thanks for the good words! please keep me posted.

Ah, OK! glad to hear. Maybe the manual validation woke up DP somehow. I was about to get back to you without any real ideas, because the validation looked perfect.

Mon, Aug 01, 2016, 11:09

Yes, I have a few size small left. Please send payment via PayPal to payment (at) madronalabs.com. $24 to North America, $36 elsewhere. Then I'll send you one next time I'm in the shop.

I have not been able to try a Seaboard, but I have an idea or two you can try.

Try recording the pressure as MIDI in your DAW. if this data is not smooth then the problem my lie with the DAW. Likewise if it is smooth, you can record some test data from the Roli and not just use that when testing to simplify the issue.

If you have a different DAW to try, that may make a big difference. Not all DAWs are equally capable with MPE data.

Also you can try different signal vector sizes in your DAW as well as any "sample accurate automation" settings.

Sorry for the trouble. This sounds like a bug that I am currently looking into with Kaivo, but I haven't heard about this issue with Virta. Please stay tuned for betas to test soon.

I don't really use the old bank/program concept. Aalto and friends just have a current patch.

If you need to load a patch under MIDI control you can check out the instructions for putting patches into the "MIDI Programs" directory.

I can't think of why else you would want banks / programs but if you have another use this is not taking care of, please let me know.

My first guess is, you need to run the installer as your personal account, in order to get the samples into your personal AppData\Roaming.

DP doesn't open VSTs?

The AudioUnits cache behavior is unfortunately not well documented by Apple, so the "delete your cache" advice approaches voodoo: a thing that works sometimes but I know not exactly why. So I can't say for sure what a missing cache would mean.

I can get more info if you open a Terminal and run 'auval -v aumu Aalt MLbs'. This will validate the Aalto AU. It looks like possibly this is failing on your system. Please send me the resulting text by email to support@madronalabs.com. Thanks!

OK! You reminded me that there used to be arrows when the patch cords were not moving. Yes, I cleaned up the interface at some point and removed these arrows. Sorry, I didn't remember that right away. There have been a lot of changes over the years!

Sun, Jul 24, 2016, 08:18

Maybe they are smaller than they were previously? I still see arrows on both platforms. They are sometimes hidden under the mouse pointer. If you can take a screen shot showing this, please do.

Thanks for the good words.

Good morning and thanks!

More bodies are definitely coming in the future. I tried a tube model for the 1.0 but it did not make the cut. I'll definitely revisit that idea, Kaivo needs more "hollow" sounds.

There will be modules from the existing synths and many others. Certainly a comb filter.

Mon, Jul 18, 2016, 10:17

10.7 or higher should be OK. You mean Performer fails to find it? Or the plugin launches but then fails? The Aalto.component should be in ~/Library/Audio/Plug-Ins/Components.

Maybe in this case clearing your Audio Units cache will help. Just delete the file ~/Library/Caches/com.apple.audiounits.cache. It will be recreated as needed.

Sorry to hear about the problems. I'm working on getting an update out ASAP.

Mon, Jul 18, 2016, 10:13

I've just gotten a few reports about this issue. I'm working on getting an update out ASAP.

Thu, Jul 14, 2016, 18:37

hmmm... try a patch known to produce stereo output regardless of input, like "simple vocoder drone." If this is still stuck in the L channel you know it's an issue with the Logic track setup. If you get both channels then it could be the inputs or a Virta issue.

Thank you very much for this note! Some stuff not relevant to plugin development is making life difficult right now and so, it's just really great to have a little unexpected blast of support. You made my morning! I need to spend more time in "modular play" myself.

I haven't put out much news lately. I'm working on the library that's underneath all my plugins, improving the foundations for the long term. Stay tuned for updates soon.

The demo will not install over a newer version. I think you can use the uninstaller that came with the 1.0.2 installer. or simply remove the virta.DLL from VSTPLUGINS.

Mon, Jul 11, 2016, 10:59

Sorry you're having trouble. I first heard about something like this (Virta audio locking up) last week. I'll try to sort this out and update ASAP.

If you have time, can you please try this Virta 1.1 DEMO for Windows and let me know if it fixes things? This could help me track down how the problem started.


Can you tell me what buffer size you are using in Live? I have heard of problems with larger buffers, over 1024. If you are using a big buffer you can try reducing it.

Paging Alex / aux13

I tried to reply to your email but it is bouncing!

You can still get the 1.0 demo here:


I don’t have the 1.0 version for personalized download, because there has been no need. Can you please try 1.0 and tell me if it gets better again? If 1.0 is better then 1.0.2 for you, I will try to find out why, and release an update soon.

Wed, Jul 06, 2016, 10:14

OK, glad you found my reply.

This 1.0 / 1.02 difference in Reaper is very strange and concerning. I will look into this and try to come up with an update ASAP.

Mon, Jul 04, 2016, 09:35

@juan, sorry I missed your post until now! Aalto was designed to make it easy to explore scales and lots of people have done this with it for years, so you should be OK. If any problems have come up i'll fix them, it's part of the process.

My most favorite composer that uses alternate tunings is probably Terry Riley. I don't think of La Monte Young as "academic" either.

Hi Tonvater, thanks for the good words.

I can see the use of Virta's tonetracking module in other contexts, for sure. I was about to say that it's impossible to get signals out of the patcher, in general.

But with Virta that's not really true! There is the one "aux" input to the mixer / output module in Virta. So if you have a way of setting up a DAW with another module that can respond to this... eh maybe it's something but since only one output, probably not generally useful.

I do plan to make a modular plugin that will have some of the modules from the other instruments. I think this is the real answer.

This has been requested before on a per-dial level as "parameter locks", which I hear is a feature that people like on some other synths. I'll add it at some point. I guess it will be reached by command-clicking on the dial or something. This could bring up a little dial menu with the lock as well as fine adjust.

Mon, Jun 20, 2016, 11:07

Good idea and the first I've heard this request. thanks for the feedback. I think 12-equal is hard-coded in case the Scales directory can't be found, so there's probably no workaround for now.

Mon, Jun 20, 2016, 11:06

I understand about this issue and will be adding some kind of "fine adjust" capability.

It sounds like maybe you are not using the relative (non-jumping) mode though? You can shift-drag any dial from a point outside the "track" (over the number is good) to adjust smoothly from the current location.

I made the combination of "jumping" and smooth dragging with live performance in mind.

You can try a higher block size in Reaper's Audio preferences.

I will download Reaper 5.2.1 for testing. Thanks for the feedback.
