hi people, and in this case, especiallly dieter,

i received a few days ago an a-146 LFO 2, and i'm a little frustrated at the point at which i
need to switch from one range to the next. bang in the middle of the range of what i
would use to produce "normal" expressive effects, i need to flip the switch and twiddle the
knob :)
the first half of the medium range is not something i would use as an expressive device,
ditto for the upper half of the hi range (i'm naturally not suggesting that there are no uses
for these speeds).

so my question is: is there a way to either a) change the crossover points or b) get all three
ranges to start at zero and cover the range up to their respective maxima

cheers,
