sounds stupid, but i donīt "dig" the behavior of the pan in the stereo mixers.
does the 4in2 stereo-mixer expect stereo or mono-files as inputs?
is the pan a real pan like on a mixing console or does it attenuate either the left or the right input signal like a balance knob would do?
unfortunately i canīt post an example sound because my system is in the studio. iīll get back to you tomorrow. maybe itīs my old "canīt see the wood" problem.

The pan is a power-pan function. In other words it maintains equal power (as opposed to equal amplitude) during the pan.

For mono inputs to the mixer, the effect is clear. For stereo inputs, it is less clear what the desired effect should be. What the 4 in 2 out mixer does is: figure out a left and right scale factor based on the power pan, then multiplies the left channel of your stereo input by the left scale factor and the right channel of your stereo input by the right scale factor.

So it seems to be quite complicated to make a simple mix of a stereo signal and a mono signal panned to the middle?
the 4 in 2 mixer doesnīt allow leaving one input unconnected as i understand.
when i want to mix 3 in 2, i have to rout some kind of dummy sound to the fourth input that i then scale to 0.
is there another trick?

I thought all signals were in stereo. I must say I'd prefer the option of maybe a darker line or a line with an 's' on it for stereo and all the rest in mono.

If you have two inputs, you could use the StereoMix2. If you have three (or some other arbitrary number of) inputs, just put them into a Mixer. If you need live panning and attenuation, you could put your inputs into a Pan or Attenuator first, and then drag them into the Mixer. The Mixer can take an arbitrary number of inputs.

so when the input pan of the stereomixer is set to 0.5 left and right channels of the input signal will run throught the mix unchanged? so the pan works like the balance knob on your stereo system?
so actually itīs not a real pan.

Hi Frank
I think that that if we stop thinking about the interconecting wires as mono and stereo,instead all wires are stereo connections, but that some modules send out the same signal on both the left and the right out puts ,then the pan control is realy a balance control but acts like a pan if fed from a module that sends mono out of it's stereo output.

Now can someone tell me which one of the following is right
audio
vidio
sterio

or

audeo
video
stereo

thanks pete

MONO vs. STEREO connections/samples:

Whether a sample or a sound input is mono or stereo has been handled neither consistently nor transparently throughout all of kyma. i'm not sure if any of this has been remedied in 5.0 (say, where do i get 5.0 documentation again?).

If kyma can't abstractly treat all stereo/mono connections and sample fields consistently then I think it is essential that kyma explicitly document what each sound does with it's input. for example, the filter sound will sum L & R. other sounds will use only L, dropping R entirely. What does EQ do with its input? What does sample cloud do with stereo samples? How about VCA? Vocoder?

Marcus - this drives me nuts, too. It is one of the most frustrating aspects of Kyma's user interface. Trying to maintain a stereo image is far too complicated - requiring separating and joining objects, etc.

Kyma 5.x does NOT address this.

this inconsistency is really serious.
what to do about it?
and where to get the full 5.9 documentation?

All documentation can be found by choosing Documentation from the File menu in Kyma. The updates have their own documentation that you can read on the web page when you download it.
