Alpha-09 proj 20something of 56: Envelope Finished

[forum]

Alpha-09 subproject: Envelope re-write. It had almost a dozen bugs to find, but now it is able to generate correct results for all the about 740 patches I ship it with. It should be a bit easier to use, because I've renamed some input variables, and the performance is definitely increased.
Next project and it should be a simple one: a "sample history." You will be able to see the value of any variable X samples in the past by using a @X notation. This can be used for:

-- writing your own digital filters

-- feedback for instance in a DX-7-like FM setup

-- first derivative of MIDI controls
