Hi,
attached you’ll find two sounds, both dealing with threshold inversing – that is, if the threshold is exceeded a ‘0’ is generated, if not a ‘1’. Unfortunately in both sounds, the second is s simple demo with optional inverse, the way I implemented this technique doesn’t work. In the first sound the inverse mode doesn’t work, and curiosly, in the second the normal mode doesn’t work (for clarity I didn’t use any random deviation).
What could I have overseen?
Furthermore, for the sound with the random threshold switch a hot parameter within an array would be great to have. Is this maybe
an idea for future extension?

About the third sound attached: unsatisfied with just one time scaler, I tried to extend that with another one - here within this context applied to the amplitude of the input, which I want to use for the feedback of a delay. The problem is that like this the feedback always seems to be at its maximum and I can't figure out/ explain why that is the case.
Any idea, advice?
Thanks again.
Best, Florian

If you are using the "of:" array, you should be able to put hot values into the array (or expressions within curly braces), for example:

!Index of: #({!c1 * 3} !c2})

oops...that's embarassing. I'm still convinced that I've read somewhere
that you have to enter concrete numbers inbetween the parentheses.
Maybe in the old (4.5) manual? Anyway, glad that I can do this now...

From the expressions you are using, I am guessing that you want to use !Inverse as a way of selecting between one threshold and another. Is that correct? If so then you need one extra pair of parentheses around the second half of the expression. In other words it should be:

(!Threshold + (!Rate s random * !Range smooth: !Rate - 0.01 s)) * (!Inverse of: #(1 0)) +
((!ThresholdInv + (!Rate s random * !Range smooth: !Rate - 0.01 s)) * (!Inverse of: #(0 1)))

for the Threshold. And for the Hysteresis parameter it should be:

(!Threshold * (!Inverse of: #(1 0)) +
((!ThresholdInv * (!Inverse of: #(0 1))))) * 0.1

Yes, that is correct...always those little things...in the meantime I...
anyway, currently I am switching this with <threshold: !T nextChaotic> and
as its input I use a 'chaotic reverb'...the result is awkward, reminds me
of the Tunnel-Sequence in Tarkowski's 'Stalker'...thanks kyma :-)
