Hi Carsten, there is a dirty way to do it.
You can make some kind of looper that machine.add yourFile.ck and after, say a bar, remove yourFile.ck, so, if you make some changes in yourFile.ck and save, you will have the saved file in the next bar.
// ----
// 
looper.ck // ----
// define your tempo 
0.25::second => dur beat;
0 => int count;
while( true )
{
    count % 8 => int patt;
    if( patt == 0 )
    {
        Machine.add(me.dir()+"/yourFile.ck") => int yourFileID;;
        8 * beat => now;
        Machine.remove(yourFileID);
    }
    count++;
}
You can create a BPM class to keep the things of yourFile.ck in tempo with the looper.
