[Feature Request] Time stretching/shrinking for midi/drum parts

[cezaryece]

Sorry if it is possible right now and I dont know how to do it, but if it not possible I vote for that possibility.

If it is possible just tell me how I can adjust duration of some midi part.
Let say I have 2 bars with 4 quarter-notes each (2 x 4 = 8) and I would like to get 3 bars with same 8 quarter-notes shifted in time to fill 3 bars.

There is currently no way to stretch midi dynamically.
Our scripting interface could be used to make such a stretch tool. Currently there are the related scripts doublespeed and halfspeed.

I have created and tested a new Python script that solves this.

There was a bug in scripts.cpp, so when reading back the modified MIDI data from the script, all CONTROLLER events were misinitialized (tick was not read and set). I have fixed this too:

                if (line.startsWith("CONTROLLER"))
                {
                    QStringList sl = line.split(" ");

                    Event e(Controller);
                    int tick = sl[1].toInt(); // added line
                    int a = sl[2].toInt();
                    int b = sl[3].toInt();
                    int c = sl[4].toInt();
                    e.setTick(tick); // added line

I am closing this. Is this the right thing to do or should I wait for review and merge?
