Just tried the demo but I am getting bad rhythmic crackles even with everything turned down (over sampling, resonators etc) any ideas? (I'm on a power pc set up for audio)

just make your sequencer to play

Set Host buffer to 1024. Set KS Buffer to 1024. reload both.

Better?

If yes, feel free to try 512 and 256 for both also. Reload both each time.

NEVER use Oversampling for real-time. Use it only for bounces.

and yes, check the Phase Lock pref. In a DAW it should be set to To Host, and you need to then start playback.

In a host like Sound Forge, you should use "Internal" since such hosts do not supply clock.

I'm fairly ignorant when it comes to the math/intervals/tunings/etc. being discussed here and will be using my ears primarily until I have a better understanding of the various settings on a deeper level.
If I have both set to 1024 and it works fine, why would I try 512 and 256? Is a higher setting better than a lower setting?

OK, but this nothing to do with buffer settings which is what we are discussing. Tuning etc is a completely different topic.

Simplified version: Computers like to process data in chunks. This "chunk" is called a buffer. The larger the buffer is, the more efficient the computer can be in processing the data. When the buffer is as big as possible, the computer will be most efficient. You will be able to get the most number of instances in real-time before experiencing drop-outs. Render times will be as fast as possible.

The downsides to using very large buffers are:

1) It adds latency. If you are playing an instrument live, this can interfere with your rhythm/timing/feel.
2) It makes the GUI less responsive. GUI updates will feel slow.

(Ideally we would use a HUGE buffer for bounces, and medium one for real-time. But we can't safely switch automatically between real-time and bounces in all hosts quite yet...)

Thanks - I will try tomorrow - I am used to having my buffer set at 64 (RME) ... I guess that means if will be tricky to play in live guitar (that is what I was trying to do)

Yes, and actually something I did not realize initially, is that using Host=64 and KS=2048 is actually WORSE than using Host=64 and KS=64.

Host = 64, KS = 2048 will give the absolute worst performance for realtime.

I"m a decent pianist, and I find 256-sample latency mostly tolerable personally... Especially for non-virtuoso type of material as would be most common to be fed into something like KS. Whole note or half note chords, or melodies of 1/8th and 1/4th seem perfectly fine to me at 256 samples. Even 16th aren't too bad IMHO. YMMV.

Interesting- I will try 256/256, I am only playing chords so I don't need a fast response, even 20ms is ok for PAD type chords. Obviusly I could render, but like to hear the sounds as I experiment, ambient guitar stuff (If I am using a big reverb like black hole) is usually about finding weird open chords that just sound right when affected.

Thanks for your help....this is something I want to buy!

I thought any topic related to KS could be discussed here, including tunings (which was just an example of a toolset list); I never got a response to the 404 error regarding a forum or to my suggestion of having a forum here. Best if I lurk here rather than try to participate.

Yes, of course it can. There was lots of talk of tuning a few pages back.

I just thought you were confusing tuning with buffer size somehow, so I was trying to help clear up any possible misunderstanding... but maybe I just misread your post...

feel free to discuss whatever you like.

I did fix the waveforms "more info" link from the web store. thanks!

re "community" link? I am not quite sure where that is found? (a long time ago I had a php forum on galbanum, but it got overrun from bots, and I'd rather not have to admin it, so I gave up on the forum.)

If you go here,you'll see Community Forum on the left menu under Information (second from bottom of list).

OK, who is going to be the first to try KS with this:

http://thesubpac.com

?

Too bad it "only" goes down to 5Hz. KS Springs go down to 1hz, and Strings go to 0.125hz.

Still, seems like a cool thing to try. Resonate yourself physically!!

Do not operate motor-vehilicles while "feeling" KS.

Not FDA approved.

We can finally create those bowel loosening frequencies for crowd control hehe

This was fun: processing some loops I played on a Hang (pentatonic percussion instrument) using hand-drawn images (Photoshop) and a tuning file form the factory library to shape the resonators - some Molekular/DNA and B2 on 2 busses add some FX:

Very interesting. Listening and "feel" music and get a massage from Kaleidoscope
