Great to play around with Kaivo today, what a wonderful synth it is!
However, I can't for the life of me seem to get Kaivo to load the presets and samples provided on the website. I've tried to reinstall Kaivo several times. I've reinstalled the presets and samples even more times, and even tried to manually move them around to Program Data/Madrona Labs/Kaivo, from Roaming/Madrona Labs/Kaivo (that did work for Aalto), but without positive results.

I wonder, is this a known issue, is it karma or did i just miss some subtle but oh so important info while instabuying Kaivo?

I'm working with:

Windows 8
Reaper 4.591
Kaivo 1.0

Thanks in advance and again, thanks for this incredible synth Randy!

I've had a similar problem with the presets and samples before. Kaivo didn't find them because they were in the wrong user /roaming map. Moving them to the right user did the trick. However, the same solution doesn't appear to work with scales. I've also tried to move them to Kaivos vst directory, but with no success.
On closer inspection, Aalto's scale map appears to be empty. The maps are there (Greek, Just Intonation, Carlos...), but there are no .scl files in them. That does not stop Aalto from loading them, so I guess they must be somewhere else...
Someone has a clue?

Windows 8


Hi there!

I'm a shaky little reindeer in the world of DSP, so I hope you'll forgive me if I'm being completely naive. I just wanted to point that out before I layed out my thoughts :)

I was playing with Kaivo yesterday (well, I play with Kaivo almost daily) feeling a childlike joy about being able to use pretty much whatever i had on my computer as an exciter for the PM part of your synth. This is the kind of personal power i really enjoy when it comes to sound design. Then a thought hit me. What if the videogame principle of "modding" could be applied to kaivo's resonator and body? What if the user could create custom models to use in Kaivo, maybe with the help of a PM design tool generously provided by Madrona Labs? That would be wild.
Now, although my experience with DSP is limited to making simple first-order low-pass filters in C++, I realize that Physical modeling is very complicated, but I still wanted to speculate on the forum about it and see what Kaivo's developer's thought about it.

Happy patching everyone!

These were really nice suggestions. Specially the one about getting away from the computer a bit to concentrate on learning the math. I will really need that to understand mathematically the FFT and bilinear transforms (and lots of other stuff). It's amazing how easy some things are when you get them. Pure Data seems like a good aid when just starting out with a concept and test ideas, although it looks like IIR filters are difficult, if not downright inefficient, to implement.

I'm going to try to not bother you with these questions in the future, but sometimes it's easier to ask a human for advice than exploring code ánd equations, so I might give in to the temptation :)

That makes sense. I feel that that is the classic dilemma when it comes to customization functionality. If the point is to make it accessible for the average user there need to be clear software design that's destined to create boundaries, maybe even more boundaries than new possibilities. After all, if someone is after infinite possibilities they might just pick up Visual Studio and start learning some math. That said, modding Kaivo is still an idea that thrills me.

Might I ask a completely unrelated question? Do you have any good advices to an aspiring sound software developer? How did you start out "back in the days"?

Yes! That was excactly the problem, Randy! I moved the samples from one user (Admin) to the other (my daily) and Kaivo finds them now. It's going to be lots of fun to test out other samples as "exciters"! Not that the sine wave didn't deliver, on the contrary :)
