hello again,
as of right now i use the sequencer on my machinedrum to send sigals to kyma to trigger things, but i cant seem to get envelopes to work how i want.
an example of what i want to do, is paste an envelope into a field so it controls that parameter, but i still want to have the slider there so i can tweak that while the envelope is also modulating it. i'd like to be able to have another fader that would could control the intensity of the envelope as well.
right now what i tried was pasting an envelope into say the frequency field of a filter, but it takes away the slider and i cant hear any change in the frequency.
another question i have, is regarding how to use different midi channels to control different envelopes. i know i could use midivoice, but how do i assign differnt instances of it to different envelopes? would i just drag it before each envelope in the signal chain?

thanks in advance for help with my newbishness!

Let's say you are using AR as your envelope. The output range of the AR is (0,1). If you would like to use that in a Frequency field, you probably want to scale and offset that value. For example

[AR] L * 24 nn + 48 nn

would scale the range of the AR to two octaves and add that to the minimum value of the C below middle C.

To control the intensity of the envelope with a fader, edit the parameters of the AR. Replace its Scale parameter with the fader you want to use as the intensity control. Replace its Gate parameter with whatever you are sending as the trigger from your Machinedrum.

Hope that helps.

Let's say that you have !Intensity in the Scale field of an AR. When you play the AR (or another Sound containing the AR) !Intensity will show up as a fader in the VCS. Right click on that fader and select Channel from the menu. You can select the MIDI channel there. You can set the MIDI continuous controller number from the entry just above (where it says Controller).

Hi m0rb1d

In addition to what SSC says you may want your frequency control in terms of Hz as that's what you are used to, but it is best to use use nn (as SSC suggests) for the envelope, and the combining as this is in log scale and it make the envelope swing more natural sounding. You could then make the frequency control Log type in the VCS to make the control more even sounding.

So you could try this.

(([ADSR] L - 0.5) * !EnvDepth* 24) nn + (!Cutoff hz nn)

You can see the - 0.5. This means that the envelope will both add and subtract from the center Cutoff frequency you've set. Change it to -1 if you want adding envelope to only ever be less than the cutoff or leave it out if you want it to only ever add. The 24 means that the max swing that the envelope will spread (when !EnvDepth is 1) is 2 octaves. You could put a bigger number in here if you wanted.

You may notice that I have used an [ADSR] instead of an [AR]. This is because every time I've used and [AR] module I've ended up replacing it with an [ADSR] and put the same formula in the decay and the release fields and set the sustain to value 1. Even if I only want the [AR] action I still end up needing the [ADSR] module.

There are two reasons for this.

(1) The [AR] module doesn't have a largo setting so it means that if the decay has not completed when the next trigger comes along the value will jump back (click) to zero before the next attack takes over. With largo set the attack will start to rise from the point it was at when the gate is triggered (no click).

(2) You can set the sustain to 0 in the [ADSR] which makes the AR happen in it's own time regardless of the note off instruction, which is often what is wanted.

Hope this makes sense

Pete

I for one, would love to hear such a feat of audio gymnastics! How did it go? I always wanted a machine drum....

Which one do you use as master? Do you use midi clock as well, or is everything triggered from the Kyma?

Their new box looks interesting
