That Radias Osc2 Tune knob...

Something I've never really understood. Anyone know why the Tune (aka detune) knob has the same range as the Semitone knob (±2 octaves)?
Usually Tune is used for fine tuning up to ±100 cents maximum (which is already more than anyone would need), but if you use the Tune knob and go from value 0 to 14 it's already detuned by one semitone, so the rest of the values 15>63 are largely defunct. The same with the negative values. Jumping up those amounts is usually what the Semitone knob is for
It's a logarithmic curve as opposed to linear, I feel it may have been more appropriate to stick with convention and spread the Tune values linearly from, say, -100cents > 0 > +100cents maximum.
I understand that the Sync- and Ring-mod attached to Osc2 benefit from a greater pitch range... Which makes me wonder why they limited the Semitone knob to just ±24 semitones (which uses 49 knob values including zero). A knob usually has 128 possible MIDI values, so they could have doubled the number of semitone values (±48 semitones = 97 knob values including zero, well within the 128 limit), and kept Tune for fine detune purposes.
As such, there are few detune values to choose from within the Tune knob, seeing as you're less likely to detune greater than ±60 cents or so (unless you're making hoovers for Hardstyle). It limits the usefulness of the Tune knob for fine tuning.
