SM better unison request

[Oberheim 8000]

Now SM 2.6.15 have strange detuning if i have unison for one voice or for layers. For example i have 8x unison for one voice and i have 100% detune, it is sounding not much detune i like. I add another 8x for layer. But the sounds is not much fat If i set 50% for detune i can hear some detuning but not much, more then 50% is sounds strange but not like 8x8. If i change from 8x to 2x in layer or 4x, sometimes it sounds similar or it is same. The detuning is sounds like 4 osc is 40% + detune and another 4 osc for - 40%. and between 40+ and 40- is nothing.

I create my own 8x unison with addative synth and make my own detune and it was sounding much better and fatter then unison mode 8x voice with 8x layer. After create this my own 8x unison voice i tried all numbers of unison in layer section. And above 4x unison i dont hear much difference. In another synth you can hear difference from 8x2 to 8x8 and is big.

And if i detune for maximum, i hear it is only for +. That means from 0 to +1 for example. This want -1 too.

It want one knob where you can set up your detuning - if knob is on 0% the detune will be as now, 50% will be detune linear - if i detune to the maximum for 8x8 voices, each voice will have different detune = from 1 to -1.
And make more detune range.

PS: sorry for my english i hope i describe it well.
