preset/settings switch wile rendering...wtf?????

ok, so i'm trying to render a midi file i recorded to .wav..... i saved a preset, have it selected, and as soon as i hit "export WAV file" then "ok", the settings switch to some anterior state which aren't even saved in any preset, and then switch back to normal (as in my preset) after rendering is complete.

/* edit */ Found it - the midi file contains CC commands which i had previously mapped to some parameters, causing them to change when playback or rendering started.
