Also curious, does v1.2 retain all the features of v1.1 (color blind mode and LFO mode) as well as the 8 new models?

Yes.
I would suggest just installing the newest firmware, as opposed to 1.1.

while holding the left button, and turning up harmonics, the model lights should light up- in order- all the way to the top. each light representing a tuning higher than the last. The LFO setting is found below the lowest pitch setting.
