Hi Falco Thank you for your reply I will try the player in XP mode as it is an easy option to activate on my version of Vista The Button I was referring to is under the Level Meter to the right of the display with the Microphone Symbol super imposed. The scroll over produces Select MIDI or Mix and I assume it is to turn the Microphone on/off Perhaps it will do something in XP Mode. If this function is working, is it possible to Layer Voice and /or Analog Audio while playing MIDI? I currently have it playing through Cool Soft Synth and use It's MIDI Mapper to select my sound font - Works Great! Again Thanks a Bunch David |
