errr...

I was trying to experimenting with interpolating arrays ... I know it was a long shot, but this error was a bit freaky so i thought I'd post it in Support.

I want to interpolate between sequencer sounds , just the control data, not the audio path of each sequencer.

So I would like to be able to have one sample being controlled by an single interpolation of 2 or more different sequencer sounds. I have have tried a straightforward use of the Interpolate sound, but of course the Kyma signal flow goes the other way when you use MIDIVoice or AnalogSequencer sound, so I can't figure out how to interp between different sequencer data, without having to duplicate the sounds that the sequencer is triggering.

For example, in the Pitches field, instead of having:
!P0 !P1 !P2...

you could substitute an expression that morphs from A to B with:

(((1 - !Morph) * !A_P0) + ( !Morph * !B_P0)) (((1 - !Morph) * !A_P1) + ( !Morph * !B_P1))

An alternative way to do express the interpolation is:

(!Morph * (!B_P0 - !A_P0) + !A_P0)

EDIT:

doh!!! The into: lookup has a different syntax of course, it needs input to output values... will try again

EDIT:

I got the Top 24 error again!!

this time, I have tried

(!Pattern into: #(
{ 0 @ {!Step of: #(1 0 1 0 )} }
{ 1 @ {!Step of: #(0 0 1 0 )} }
{ 2 @ {!Step of: #(0 1 0 1 )} }
{ 3 @ {!Step of: #(0 0 0 1 )} }
) )

but it gives me the Top24 error....

now i'm stuck...

My instrument is called Probability Beats, because as well as switching toggles in a matrix to trigger each hit, each toggle has a slider that determines the probability of execution when its turn comes around. Therefore, each basic sequencer has the ability to 'improvise'. For example, if a toggle is switched on and its probability is set to 16 (the maximum), then it will always trigger when its turn comes around, if set to 8 then it will only trigger half the times, if set to 1 it will trigger 1 in 16 times etc. Therefore, programmed beats take on infinite variations.

I also added a function that allows each sequencer element to change direction on the fly, left to right, right to left, both etc. In tandem with the above idea, the beat patterns are constantly evolving, even with a very simple (fixed) 16-step program.

Now I would like to add a powerful preset structure that will allow for expressive Live performance, and also algorithms that will allow Probability Beats to improvise by itself, working towards denser or sparser textures at the touch of a button etc.

I am also implementing: fills, looping functions, bouncing-ball gestures, poly-rhythms, interpolated changes in note duration (for example to allow a single sequencer element to interpolate between a simple 16th note shuffle rhythm, and a simple 8th note shuffle rhythm over the course of two bars, creating overlapping rhythmic textures etc.).

Well as I said, since it seems we share a common goal, perhaps we could bounce a few ideas about on this forum, and I'm sure it will lead to a more interesting end!

All the best,

I aknowledge that you are further along the Kyma path to enlightenment than I am, so I know you can be much more ambitious with your code, I would like to see how you scripted your way around interpolating array data...

Here is a section from my sequencer, thought you might like the circular 4 source MUX fader... It also features the bank fader technology we designed a while ago...

... I have tried interpolate presets , inside a larger sound . I tried 2 of them, controlling the preset of 2 seperate AnalogSequencer sounds. This works, and is interesting. But, in taking control of the parameters of one sequencer ( which inevitably contains a !BPM hot value for example ) , you lock out control of the BPM. The BPM can no longer be changed for the whole sound.

Is there a way of makng interpolate presets ignore this paramater when it does the interpolating?

I figured out the solution to my problem above.

If there is a parameter you don't want to interpolate through the interpolate presets Sound, its as simple as setting that hotValue's fader/button/widget to 'Affected by Presets - No' in the VCS of the sound that will be interpolated, as you are setting its presets - then it doesn't get controlled by the Interpolate Presets sound..

brilliant

You know, I'm excited about this discovery, because it opens up a whole load of interesting directions for putting limits on chance, something that my professor at Uni taught me many years ago. He called it 'fixed-field improvisation' - i.e. making free choices that are within pre-composed boundaries. These choices could be interpreted by a performer as harmony, rhythm, texture, dyamics, duration - In Kyma, these generated choices could be applied on a myriad of different levels.

I also feel that a dice roll , or mutator , triggered from conditionals within the sound structure itself rather than manually via VCS, is now a possibility. This is something I have been searching for in my own generative music research for some time - a way for a composition to mutate its structural attributes over time, whilst maintaining possibilities of interaction from a performer.

I'll see if i can create something beautiful out of all this ...
