@angy @klangfuchs the GUI requires Metal and this will work on some but not all 10.13 machines. ANy machine running 10.14 or higher is guaranteed to have Metal. I plan to work on an OpenGL version for Mac.

@maserna I'm going to fix the Windows installer to overwrite pervious verisons. Meanwhile you can remove the VST3 file from C:\Program Files\Common Files\VST3 and run the v1 installer (from the product page) to get v1 back.

thanks @atelierminceur.

I should probably just never say dates—since there's only one of me, illness burnout or family emergencies can completely throw off my estimates. But on the other hand I do want to communicate what my plans are.

I'm still shooting for this spring on a Sumu beta.

I can say with a confidence that the Aaltoverb beta will be out later today.

That link came up "topic not found." Anyway I've heard of the CLAP initiative and I'll be happy to support it.

Yes, this is why I'm migrating all the plugins from VST2 to VST3.

Here's a new tutorial on how to get your Windows VST plugins like Aalto running on Arch Manjaro Linux: https://madskjeldgaard.dk/posts/vst-manager/

Thanks to Carl Testa for sharing this!

No news on a native port for now. I'd love to work on it but I have other things to finish first!

That's correct, I have not released native arm versions of these plugins yet. I can get to this work after Sumu ships or is at least in beta.


I don't even have a target date right now but I will be working on it after Sumu.

Thanks for writing. More than a few people have asked me over the years. My understanding is still that the overlap of Pro Tools people with "boutique soft synth" people is not very big.


I'm shooting for a beta in January.

thank you! I"m getting there.

I was working hard to get it out last week but got sick and now it's Christmas eve all of a sudden. More soon, then, after a little break. Happy Holidays.

From now until December 15, all our software is 30% off. Thanks for helping us navigate 2021!

There's no code to enter for the sale this time. A code is kind of fun. But on the other hand there are always some people who don't realize there's a code, or have trouble entering it, etc. So, the discounts are now getting applied automatically at checkout until the sale ends.

Also, we've added more ways to pay on the site. You can now choose Euros instead of USD at checkout. This opens up a range of payment options people have been asking for, especially where credit cards are not as common. These include SOFORT, giropay, SEPA Direct Debut, iDeal, Bancontact, Przelewy24, and EPS.

Stay tuned for more info on Sumu and on the Aaltoverb 2 public beta coming next week!

Thanks for offering, I appreciate it. I'm shooting for January.

Thanks for the kind words.


@fneeee Thanks for your support!

much better, thanks!

this is not much but it's what I have:

file specs:
44, 48 or 96 kHz
1-4 channels
16 seconds long or less.

I use Audacity to put the multichannel files together. It's free and works reasonably well for this task. I use Logic to do any fancy editing or EQ, bounce each track, and simply put them together in Audacity. You may have your own good way of making multi-channel WAVs to your specifications, but if not, here's how to do it in Audacity:

To stitch files in Audacity:
First: set up custom Export in Audacity by selecting Preferences -> Import/Export -> Use Custom Mix.
then for each palette you go:

  • New file (cmd-N)
  • Import multiple (cmd-shift-I)
  • select the tracks you want to include in the palette. Having them named already so they alphabetize from low channel to high channel will make this easier because they appear in the right order.
  • for each track: if it is Stereo, click its drop-down menu and select "Split Stereo Track" then click the "X" to throw away one. You want 2-4 mono tracks. I always have to do this because Logic won't export mono files as far as I can tell.
  • do any fade-ins/outs you want by selecting all tracks and "Effects…"
  • select Export (cmd-shift-E) and name the output.
  • The export dialog comes up with lines connecting tracks and output tracks. You can use this dialog to direct tracks to output tracks, and select the number of output tracks, but I find it a little fiddly so for me it is easier to just to the Split Stereo Track thing beforehand.

Again, there might be easier ways now!

OK, things can always change if I hear about a more general need for a feature. Meanwhile I try to keep things as simple as possible.

The dial at left is the usual MIDI pitch bend range. The menu at right should control the MPE pitch bend range. So setting the octave range to 0 will turn off MPE per-note pitch bend.

There are a few choices people have made for MPE pitch bend range. The intent of the menu is to make the synth compatible with the different environments. A one-octave bend range offers quite a lot of precision. How much? Let's see: an octave is split into 16k pitch values, so roughly 1.3k steps per semitone or 0.075 cent.

If you need to get more precise, you could use the usual MIDI pitch bend monophonically or in unison mode wiht a smaller range.

I'll add ARM support for all the plugins over the coming year.

Thanks for all the kind words!

wonder if I should sell my Paca.

I wouldn't!

Will the partials file import be in proprietary format or simple text that can potentially be outputted from OpenMusic or SPEAR?

It will definitely be open and documented. It's just text for now—this could change for performance reasons.

"learn" can only be for midi learn functionality, right? Please add that to Aalto and the others as well in the future :-)

Yep! A bit annoying to do with VST3, which has been one of the stumbling blocks this year. But such is life

Is 64 partials using the parallel side of the Intel processor?

Yep! (and ARM)

That look great Randy. My only concern is the GPU utilisation.

You should not need a powerful GPU. typically I'm using the built-in one on my Macbook Air.

In my relatively short music adventure (going on 3 years now since I got into all this stuff), never have I ...

thank you!!

Wow, I´m really exited about that for a very long time. Will you publishing any peek-a-boo audiofile snippets teasers?

for sure!

Only thing I wish was a savable code-file (you know it´s still not working for me in any form, except going copy/paste directly from your homepage).

This should work, please email me for support.

If that means you're not able to use it at all and you want a refund, please send me an email.


There's currently no way to do this in Kaivo.

I appreciate hearing from you. I'll look at ways to make all the plugins as accessible as possible in their new versions.

Aaltoverb is a VST3 plugin, not VST2. Unfortunately I don't think Ableton made the decision to support VST3 in Live 9. You could try upgrading your Live 9 to the latest, or try a demo of Live 10 to see if this is indeed the problem, and then decide whether to upgrade later.

That is a very beautiful user interface, like a poem.

I think there are similarities between these art forms! collecting a set of elements and presenting them in ways they can be recombined for multiple meanings... thanks for the kind words
