Calculating freqModLFO

Post by StevenHamamoto »

HI, all.
I'm analyzing airfont380 final.sf2 and I created spread sheet soudfount analyzer.
But for "Mod LFO Frequency", the value is different for Viena and my analyzer.
My analyzer compute it from f(genval)=8.176 * POWER(2,(genval/1200)).
Would you tell me why?
You can see related creen shots, from below URL. (my facebook time-line).
for example -828 is a genAmount raw value.my analyzer saids f(genval)=5.06793

The value that you show on you Facebook site for Viena is the Preset value, not the Instrument value. Preset values are not absolute but equal to a multiplication factor to be applied to the Instrument value. Hence, the final value depends on the Instrument.
