1. OSC signals need to be a value between 0 and 1, where MIDI signals are usually in the range 0...127. So the parameter forwarder will do some math to 'translate' the values to something OSC can work with. So 110 on MIDI could well mean something like 0.7 on OSC (probably something closer to 0.85, but you get the idea).
2. This shouldn't be the case. If you send a mail to firstname.lastname@example.org
