The Kronos provides this information in the parameter guide:

Code:
EG Value Actual Time
00       0.667 ms
10       10 ms
20       44 ms
30      104 ms
40      224 ms
50      464 ms
60      944 ms
70      1.8 seconds
80      3.8 seconds
90      10.9 seconds
99      87.3 seconds


Unfortunately, in the Triton ST parameter guide, the only information provided is similar to this:
Code:

Attack (Attack Time) [00…99] Specifies the time over which the level will change from note-on until the attack level is reached.

There is no relation from value to actual time.
Since the mapping is non-linear, it is necessary to specify the breakpoints and increments in each range of values.

Has anybody ever worked this out? It is quite time consuming to analyze by recording snips of sounds, varying the parameters, and measuring in a waveform editor, so if anyone already has the information I would be delighted if you would share!

Thanks!

I went ahead and made the measurements.
Above value 10, the Triton and Kronos ranges are very close - within the measurement precision.

The TS seems to have tight time resolution in the short attack values. Zero is really zero. I have not done the corresponding tests on the Kronos to verify that the fastest rate is .667mS
I'll just believe the published values.


Code:
99   87 sec
95  28.8 sec
90   10 sec
80  4 sec
70  1.9 sec
60  965 mS
50  509mS
40  250mS
30  137mS
20  71mS
15  56mS
10  11mS
8   5mS
7   3mS
5   1mS
3   0.25mS
1   0ms
