===== Introduction =====
i fell in love with a zoom livetrack-l12, a multitrack-audio-recorder, in a compact design, severell submixes, parametric eqs, compressor, efx and a extra master-track-recording, and that for a good price...\\
but it doesnt have midi... in specially it does not have a midiclock.\\
so when i have to make a track new, or i want to overdub a track, a track that is Midiclock-Driven a sequencer track for example...\\
\\
So with this device, i lose one Audio-Track, because i use this one Audio-Track, as a Click-Track, it records Audio-Rectangle-Pulses, which are a converted Midiclock-Pulses\\

when i then playback the Click-Track-Recording, it converts this Audio Pulses back to Midiclock-Messages.

Thats all, not much code, stripped down, running thight.
