Pearl Posted July 13, 2004 Report Share Posted July 13, 2004 Hi there ...Because I didn't find a way to control the MasterVolumen in CubaseSX-GenericRemote, I want to try to integrate an encoder in my MidiboxLC to control the LC-MasterVolumen (usually controlled by one Motorfader).Is there an easy way (means some additional code in "enc.inc") or is this more complicated ?"No Touchsensitiv" is not a problem for me.Thanx for any ideas ...Bye Pearl Quote Link to comment Share on other sites More sharing options...
TK. Posted July 14, 2004 Report Share Posted July 14, 2004 Hi Pearl,the encoder just only has to send PitchBender events at Channel 9Best Regards, Thorsten. Quote Link to comment Share on other sites More sharing options...
Pearl Posted July 15, 2004 Author Report Share Posted July 15, 2004 Hi TK ...Cool, Iwill try to integrate this in the next days :)Bye Pearl Quote Link to comment Share on other sites More sharing options...
Pearl Posted July 29, 2004 Author Report Share Posted July 29, 2004 Hi everybody ...Here is my solution for handling masterfader-event with an encoder. I hope that I got all the changes ;) .Change in lc_mproc.inc: ... ;; -------------------------------------------------------------------------- ;; Ex has been received: move motorfader ;; -------------------------------------------------------------------------- LC_MPROC_Received_Ex ;; mask out MIDI channel (== fader number) movlw 0x0f andwf MIOS_PARAMETER1, F #if MOTORFADER0_IS_MASTERFADER == 0 ;; do nothing if fader number >= 8 movlw 0x09 ;including "MasterfaderEvent" this has to be 0x09 !!!
