There is no unison mode in Pentagon/Z3ta+.  I have been lobbying for this
and it is a possible future addition.  What they do have is 'Multi'
oscillator algorithms which model 4 waveforms detuned per osc.   This is
different to true unison mode which should be whole voices stacked and
detuned.  The beauty of unison is that it can be applied to any existing
patch, for example a synced osc patch, and the synced sound would get fatter
depending on no. of voices and detune amount.   With the Pentagon/Z3ta+
'multi' method the synced oscillator would be replaced with the multi osc
giving a totally different sound.

I have to say that I find the exsII 'unison' mode disappointing,   It does
sound to me like the 'multi' osc system described above.   At note on, all
waves are in phase and then proceed to drift apart.   This give short notes
a different sound to longer ones.   I have a Korg Z1 and it has a great
unison mode that properly detunes whole voices with no phase-synchronised
note starts.
