norns.enc.sens(target,val) and norns.enc.accel(target,bool) should do it.
for enc_sens, higher values add resistance.
for enc_accel, default is false – true helps fast turns do big jumps.
we’re capturing all this stuff for a new series of microstudies (which folks will hopefully contribute to!), super helpful for you to have asked, thank you! found this in encoders.lua, but this sorta digging shouldn’t be necessary.
