Hi all

Looking at the envelope generator it seems very complicated

Does anyone know how to set it up as a basic ADSR env

Well for starters it is different per engine. For the most basic ADSR, Polysix is good to go. I guess you're looking at HD1 or AL1 or something. In that case, basically you just get a few extra stages. Going from memory can't you simply set all "start", "break" and "slope" parameters to zero? That would leave you with a basic ADSR albeit one where you can set the attack and decay level as well as the time.

Otherwise, be sure to check the relevant section of the Parameter Guide.

To expand on what SanderXpander has said …

With a traditional ADSR envelope you only have a level for the Sustain segment but with HD1 you can specify levels for the other segments as well. You also have what can be thought of as an additional decay stage called Slope. So using a filter envelope as an example you might set up the envelope like this …

Level Parameters ...

Start = 0 (start at current filter cutoff frequency)
Attack = +99 (opens filter to max at end of attack)
Break = 0 (Slope time will be zero so this stage should be skipped)
Sustain = S (this is the S in ADSR)

Time Parameters ...

Attack = A (this is the A in ADSR)
Decay = D (this is the D in ADSR)
Slope = 0 (this is like a second decay stage and not needed for ADSR)
Release = R (this is the R in ADSR)

Sorry Sander for being a bit vague

Its with AL1

Thanks for the explanation Bald Eagle its a bit clearer now

What does the Curve part do

And is there a diagram somewhere about this

Thanks for the responses everyone

[Broadwave]

The curve is to give different responses...

Most digital envelopes have a linear response (a straight line) and analogue is generally curved. The Kronos, unlike most synths, gives you control over the shape. A curved response more "natural" sounding.

Try modulating the pitch of an oscillator with an envelope set with a straight (linear) attack, and then change the attack to curved - you'll hear a difference in the way the pitch rises.

The chart below shows a graphical representation of what's going on between linear (top) and exponential (bottom)

Maybe offtopic, but I always wondered why there is not a e.g. 8, 10, of x-stage 'ADSR' envelope possible. It would cost a little bit of more parameters, but performance-wise there should be no difference.
