am finalising a version that allows control of MQn, it acts very much like lifting the needle on a turntable, ie the user makes a change and returns the player to best quality, other players use other threads or are constantly checking for user input, both of which affect the SQ.

it uses a mqncontrol.exe as well as mqn.exe

while mqn is playing music, the user can press a key and a separate console appears where the user can pause, fast forward\rewind and skip tracks forward/back.

what happens is that mqncontrol.exe changes the page protection of the mqn sound buffer to no access, this way the render loop doesn't need to check for user input and mqn doesn't need a separate thread to be constantly running.

mqn immediately throws an exception as it cannot read the sound buffer

mqn has an exception filter which is called, this starts a menu thread and resets the page protection so the music can keep playing

the menu thread opens a new console and waits for user input

the user makes changes and presses x to exit the menu console/thread

the menu thread is stopped

mqn is returned to highest SQ state.

will be released next week

needless to say, no other player does it this way, yet.
