hi there.
i have constant problems with the attack-phase of sounds. in low keys they are very likely to produce unwanted distortions. i usually trie to smooth every parameter. but this doesnt solve the problem entirely. and it also diminishes the the timing properties.
does anyone have got similar problems????

Are you talking about samples only, or other Sounds?

By distortion, do you mean time stretching or amplitude crunches?

yep.
with samples i have problems during release. if i donīt play the whole sample, i get clicks even if i do a release time of 0.5 s.
with the other sounds (like the one which i have posted) i have problems during attack.
espacially (i guess) if i trigger a new sound when the other envelope is not yet finished.
as i understand it, should the !KeyDown command make a 10ms fade before triggering the next sound. but maybe this doesnīt work as intended?

Is this the Sound that you are having problems with? I don't see any Samples or uses of !KeyDown...

hi sm
Try this attached sound. I've had to cut it down to 2 note poly as I only have a cappy 66. You could try putting the velocity control in the scale field of the filter and getting rid of the attenuator. The ADRS has a largo control that the AR doesn't have. They were both designed to work with poly samples which ment that as soon as a note steel happened the AR would instantly reset to the start point . Hence when used in a synth it tended to click , but ADSR has had largo added to allow for a mono synth type control. In largo mode , what ever level the signal has dimminished to at the time of retrigger is the level that the new attack will start its rise from . Also I added smoothed to the velocity control as this was another source of clicks.
hope it helps.

thanks pete for your help.
where did you get the information about the differences of the AR and the ADSR prototypes.the manual says nothing about it?
nice little "geheimtipp"

well sm
I'm the one who asked for the largo mode to be added and as it was such a new addition it probably missed the manuel.

aha!
this brings up the question, which things are new in 5.09. either i missed something or...hm?
can anybody link me to the new added features since kyma 5.0?

The changes since Kyma.5 are posted on the download page. The changes between 4.5 and 5.0 are available inside Kyma. (Choose Documentation from the File menu, and click on the What's New in Kyma.5 link.) For example, the Legato parameter is described on the top of page 5.

P.S. Shouldn't you boys be in bed at this hour?

regarding the post at the top of this
topic, i'm wondering if you are placing
your amplitude envelope sound in the scale
field of your sample/oscillator etc.
there are many examples shipped with kyma
that do this.

sounds that do this get a "zipper" effect from your envelope because real-time fields are evaluated at a mere 1kHz.

instead, multiply your sound source
by the envelope with a vcs sound. this will envelope your sound at the sample rate instead of 1kHz removing the artifact.

oh yes.
i guess this is the definite answer to my distortion/zipper problem. i thought the shipped examples where the best way you could go....
just one thing remains: what exactly is a vcs-sound???

I think Marcus meant VCA Sound...

ok.

is there by any chance a list or something where one could look which sounds work on 1kHz controll mode and which on the sample rate?

yup...marcus meant "VCA".

all real time parameter *fields*
are evaluated at 1kHz. sound modules
themselves are evaluated at the
samplerate. very different types.

Yep, Marcus has it right. There *is* one exception to this: if you paste a Sound into the Envelope field of an Oscillator and remove the L after the pasted Sound's name, it will be evluated at the sample rate--that comes in very handy.

This is big if it applies to all variable fields in all sounds. Or does this apply only to Oscillator envelope fields?

i did not know about the exception
for the oscillator sound. nice!
