Hi, I have those warnings when pd starts up, I never worried about them but would like to know how to fixed them:

Error number -9999 occured opening portaudio stream Error message: Invalid number of channels.

could not open midi output device number 1: Invalid device ID. (this is for Midi interface, It seems that I cannot localise the outputs

(CSYNC DEBUG) : GetProfileBySpaceFromShmem returned NULL for 'RRRR' : Calling Dispatcher.

any idea ? thanks
