MadRouter is made for that. Free for MM licence owners. Free download in yourspace. You can use high resolution MIDI conrollers for input and OSC will be floating point, so you'll have 14 bits precision (high res MIDI CC)
For instance, source URL "/midiin/MadRouterMidiIn/1/cc1[hr]" and target URL "/osc/MadRouterOsc-0/address1" will forward all events from MIDI cc1 high resolution to OSC out on address "/address1"
If you want to forward 10 HR CCs: "/midiin/MadRouterMidiIn/1/cc[1-10][hr]" / "/osc/MadRouterOsc-0/address[1-10]"
Read the manual (menu help) it shows all the great things you can do with it.
