Hi Mark, I did try starting Kontakt 2 before starting Midinotate Composer without any luck. I knew I had to do that because I was previously using VSampler with Composer.If this helps, when I open the midi device setup these are the four devices that are displayed,SpeedShift MidiCable 1 and 2,E-DSP Midi Port{ EMU 0404 Soundcard and MicrosoftGS Wavetable SW Synth. These devices were in the MIDI device setup in Composer before I had installed Kontakt2.Composer is able to recieve MIDI information but I am still unable to get Composer to communicate with Kontakt2. Thank you Sherry and Mark , Andrew
