Yeah, that's a pretty hefty download. I definitely understand 
that! :-) And I understand it's asking quite a lot for users who 
don't already have it on their system to d/l it. 

A coupla points, I'm pretty much married to C#/.Net right now, which 
is why I chose to use it to write the application. I've also written 
a lot of tools in the past, MIDI libraries, DSP algorithms , etc., 
in C#, so to write this app, it was almost just a matter of putting 
it all together. Fairly easy.

Having said that, I can understand anyone being wary of 
downloading .Net + DirectX 9 just to use my program. In fact, I have 
considered rewriting it using just C and the low-level Windows API. 
That would mean that almost anyone with Windows could use it, no 
need for any runtime, or whatever, if I do that, and it's a big IF, 
it's weeks and weeks away. In the meantime, I hope this program will 
find some use.

Sounds cool. Are you talking about the overall amplitude envelope? 
How exactly is it extracted?

What I would love to do is somehow use the envelopes for controlling 
the individual partials in my program. But here's the thing, it 
would be easy enough to analyze the waveform at several points and 
use that to form a composite few of how the amplitude of the 
partials change over time. But then how do you make the K5's 
envelopes correspond to those values? That's the question I have.
