Hive 2. UHM envelope, is there something i dont get?

[DrEntropy]

In this simple snippet, the final amplitude when moving through the wavetable is not 0, instead it looks to be about 0.2. However if I swap for the simple two point envelope (the second one I commented out) it works fine and the final amplitude is 0.

Code: Select all

NumFrames = 256

Wave "sin(2*pi*phase)"

Envelope curve=linear L0=1 T1=0.5 L1=.75 T2=1.0 L2=0.0
// Envelope curve=linear L0=1 T1=1.0 L1=0.0
Wave "env(table)*x

I am sure I am missing something obvious, but I cant seem to figure it out. Any help appreciated!

(Yes I realize that is kind of a contrived example, but I this is the simplest code exhibiting the 'problem'. It is likely that the 'problem' exists between the keyboard and the chair)

Thanks for any help Hive experts!

I believe that the T1-Tn values need to add up to 1.0, so T2 should be 0.5.

Aha! They are deltaT's not absolute times, that was what I was missing! (I had assume that that these were the time of the events not the time between events, if that makes sense).

Thank you very much. I should have looked more closely at the examples.

No problem. Personally, I would prefer absolute (fractions of) time (0-1) rather than deltaT.

Maybe there is a way of doing that, but I haven't seen how.

Urs?

No, it's all deltas... which was supposed to be more fail proof since segments always stay in order. OTOH I have been confused by it as well, several times.

Would it be possible to have an alternative (additional) envelope system Urs?

I‘m thinking of exporting Z3 Spline based envelopes and waveforms to .uhm... copy/paste and stuff...

[Urs]

But it is also possible of course that we add an attribute to the existing envelopes to have absolute time values...

I think this is an option.

It might help to change the documentation to use \Delta T0 , \Delta T1 etc just to make it clear that is what is needed. Anyway, very fun sound design tool!
