Nord Lead 4 (NL4) performance slot detune workaround

[synthmutt]

The Nord Lead 4 does not have a detune parameter for slots of its performance. In the past, I had set different fine tune amounts for Osc2 in the programs in different slots, but I hadn't found a way to alter the pitch of Osc1; however today I seem to have stumbled upon a way to achieve that separately within the program for each slot:

mod env attack = 0, decay = Infinite, dest = Osc1+2, and the mod env amount now gives a positive or negative detune

I had never tried this before since the manual specifically states, "Osc 1 and Osc 2 pitches are not modulated at all by a Mod Envelope Release that is set to infinite".

This is with OS version 1.30. Can anyone else confirm that their NL4 does the same?
