One other comment, i'm curious, has anything changed with regards to the output of the sound engine in a manner which might affect the tone, something isn't quite right with my presets, i can't quite put my finger on it ..

It's possible that the sound has changed very subtly. My intention was not to change the sound, however many things have been rewritten. When I make changes to the audio engine I listen to a series of reference patches I know very well. If these sound as they should, then all is well.

If you have a patch that sounds different enough between versions as to constitute a bug, you are welcome to send it to me for listening.

Thanks for the comments. I could not reproduce the issue with 0 giving any change or +12 not being an octave.

Are you sure you have your attenuverter set to 1.0? Try double-clicking it to restore the default.

Do you have glide on? If so, the output value will always be a linear combination of two adjoining sliders based on the current time value. So if you are doing testing like this you have to make sure glide is off, even when the rate is 0.

I tried all the quantize ranges, and I did find some oddness with |range|

Out of all of these, Reaper is the one I have tested with and, I think, that the most people use. So that may be a plus. Not to say the others won't work and maybe provide some advantages.

Reaper does have a down side in that the graphical handling of plugins is not the smoothest. But that's improving and I've always found its audio engine to be top notch, it's an excellent value.

I would check the Live intro as well.

Traction has a sort of simplified approach to a DAW that you may find very usable.

On Audacity: I don't know why it would sound "thin." Basically any program capable of recording should be getting the same bits from your interface to the hard drive. I would look at your interface setup to see if there's some big incompatibility, or, failing that, use a spectrum analyzer plugin to try to quantify the difference.

That's great to hear. New betas for Windows coming very soon, I think.

Mon, Mar 06, 2017, 09:58

I really want to. Need to find some reliable local help to do provisioning.

Fri, Mar 03, 2017, 12:25

I'm making progress here. To get some of these big speedups I moved the plugins onto my new madronalib framework sooner than I had planned to. (More on that soon.)

Unfortunately there was a big hurdle with this new and awesome code on the 32-bit Windows platform in particular. It's taken me some time to figure out a solution. I just compiled something that works on Win32, so I'm hopeful that I can get to these other reported issues and release soon.

I think what the original poster is referring to may just be the oscillator drift. I can investigate more after this release.

Hi Brendan,

Sorry, I don't do license transfers. I have a very unobtrusive demo version, and I advise people to try before they buy. Please see the License Terms section on the Aalto page for all the details.

[EDIT March 2017] NOTE: This conversation is from 2013! Currently license transfers are allowed for a small service fee. Please contact me for details.

I'll send out a new Windows beta soon. Please stay tuned and give it a try.

Tue, Feb 28, 2017, 10:33

Thanks a lot! There is so much stuff rewritten for this update, we're bound to run into a few things. Will investigate.

Mon, Feb 27, 2017, 09:07

OK, thanks for the report. Checking audio input incl. meter response would be part of my normal testing checklist. However, it's possible for things to break in ways that manifest only randomly. I'll check this for the impending release.

A setup with a single instance in a minimal DAW seems like a good solution for you. DAWs do not take too much CPU, generally. They add complexity but you can set this up once and forget about it.

Reaper is a good option and inexpensive.

A newcomer on the scene is called Gig Performer. They are trying to support just the use you envision. I have no experience with it myself yet.

To get a multitimbral use I would make two instances of Kaivo on different tracks and use each on a different MIDI channel.

Thu, Feb 16, 2017, 09:38

Your kind words are appreciated here! Stay tuned for an update very soon.

Tue, Feb 14, 2017, 07:13

Other people have asked for the ability to store Kaivo samples on a different disk. I'll be adding that feature when I can.

I do use Seib's VSTHost sometimes on Windows. For really quick launching I use the "Plugin Host" that comes with JUCE. You have to compile it yourself though.

Mon, Feb 13, 2017, 10:33

Welcome aboard and thanks for the good words.

The "mod cc#" dial controls the number of the cc message that comes out of the "mod", "+1", and "+2" outputs. So if you set the dial to "14", the three outputs send the values of CC messages 14, 15, and 16. This is in the manual on p.32–33. The explanation could probably be better.

The pitchbend control is added to pitch before coming out the pitch output of the KEY module. As you note, it can't be assigned to anything else. I have never seen a synth that's able to to that, so I never really thought of it! MIDI kind of sets us up for this because pitch bend is not a CC#, it's a separate kind of message.

I think Kaivo should let you import samples in demo mode. The readme file that comes with the installer has a quick rundown of how to make your own multichannel files if you want to do that. Otherwise you can just use the "import" feature in the granulator. If you are just adding your own files by hand, you have to move them into the Madrona Labs directory. There is a maximum length of 8 seconds for the sample files so if you just moved them in yourself, it may be choking on that.

Grain length is totally independent from sample files and is set up in the granulator engine by the "pitch" and "rate" and "overlap" dials.

I don't know what you mean by "can I use all samples."

Out of the two synthesizers I recommend getting started with Aalto, it's the main one a lot of people reach for every day, and you don' t need external samples to make great sounds. Kaivo is more specialized.

Great news! This kernel bug was preventing isoch USB, is that right?

I'm excited to see your setup in action when you have time to document it. I would also like to put together a guide to making the raspberry Pi solution work and get it up on the web site.

This also fires me up to complete v.2 of the touch detector.

Are you using the Linux Soundplane driver that Per Eckerdal came up with? That was created "on the way" to getting a Windows driver working, but we never got all the way there. If you need any kind of assistance or encouragement with the Windows work, let me know!

MEC seems like really interesting work and I can't wait to check it out.

Sat, Feb 11, 2017, 12:22

Thanks for the detailed feedback. I'm getting back to the Soundplane software now.

The first thing I'll be working on is the new touch detector. Hopefully this will improve CPU usage a lot, as well as the edge effects you are noticing.

A lot of these other things were on my list too, and now they all are.

I would like to improve Kyma support, but it's a bit slow for me to get feedback. Maybe I could get a loaner machine from Symbolic? I'll ask them after I can get some of these more major things under way.

Thanks for the update. I'll try the most recent Reaper.

The fixed size refers to the block size used when processing audio. you should be able to set this to a fixed value in Reaper's audio device preferences. I just checked it out and I don't see the "fixed" language, so sorry for the confusion. That is from FL Studio, I had it mixed up. In Reaper it looks like you want to click "request buffer size" and enter a value like 256 or 512.

The next Soundplanes will be Model Bs. There hasn't been much movement on it because I've been so focused on software here. Well, I do have the table saw set up. :-) I'll be excited to show pics of prototypes, etc when I can!

Wed, Feb 08, 2017, 07:00

Working on it here. There's no one big thing to fix, so I'm fixing 100 little things. I'll post a new beta soon.

Mon, Feb 06, 2017, 08:47

Thanks for the additional info. These hints may help me find a fix. The different methods may send events at different times—one is sample-accurate, for example.

Mon, Feb 06, 2017, 08:45

I would like to add this feature. It's on the list.

Thu, Feb 02, 2017, 18:32

No way to import / combine multiple files at once. This would be cool, but would take me a while to accomplish. At the end of the readme : http://madronalabs.com/media/kaivo/_read_me_first.txt
there's a short guide on putting together multi-channel files with Audacity, which is what I used to make them.

Tue, Jan 31, 2017, 11:37

Thanks much for the info! I hope this helps you out, Wells.

Mon, Jan 30, 2017, 09:32

Hi Wells, I've never had the chance to try Push so I'm guessing a bit here.

At one point I moved the location for presets from ~/Library/Plug-Ins/Audio/Presets/Aalto to ~/Music/Madrona Labs/Aalto. It's possible Push / Live are looking for presets in this old location. You could try moving some there to check.

You could also try the VST instead of the AU.

Do you know if Live is trying to load presets in .aupreset format? That's a custom AU thing I moved away from.

I'd like to make it work with Push, it's a cool piece of hardware, so I will look into this.

Thu, Jan 26, 2017, 12:03

Thanks. Please let me know if you can find any more information, such as one patch that this always seems to happen with.

I would not call this a crash, but rather an audio freeze. Not that it's not bad! I think this is likely the same issue as posted here under "Kaivo stops making sound suddenly." I'm working hard to track it down. Thanks for your patience.

Wed, Jan 25, 2017, 09:10

Thanks for the info, I'll see if I can find a difference between patches here in Reaper. It was working for me in Reaper for the last release so I'll be sure to update Reaper and see if that changes anything.

It is possible that you had the "fixed size buffers" setting on previously but the Reaper update changed that?

It's frustrating tracking these things down and at a certain point you can find things that look like patterns where there aren't any. It's possible that a bug only causes a symptom more or less randomly, so the difference in patches or the number of voices could be just the result of randomness (leftover stuff in memory, actually), and different next time.

Tue, Jan 24, 2017, 07:41

I think I know what you are talking about with these issues. I do have plans to do a pass on the sequencer and its UI for consistency / precision.

First I have to fix other problems that are affecting more people more dramatically, which you can read about on the forums here. So if you don't see a fix in the very next update don't lose heart, I'll get to the sequencer as soon as I can.

Virta 1.0.1 is released.

This update fixes a problem with audio input for all DAWs on Windows. It is available in the "My Downloads" area if you have a license, and the demo has also been updated. The Mac OS version is unchanged from 1.0.0.

Mon, Jan 23, 2017, 08:56

OK, I'm having another look at this. It's one of only three issues I'm working on for the next release, so hopefully it won't be long.
