Hi Neo...

Even the best written code can be hard to understand after we have not touched it for a month or two, let alone a year or more.

Yup, I often do a search for something and come across an upload I have written and totally forgotten about. I read it and think did I actaully write that?

So, I learned the hard way many years ago not to write "fancy one liners" and write well documented code and scripts.

Going slightly off topic here with the second quote I was on a Python ML, (they were so obnoxious that I have long since left), and the big guns on there said there was no need to add comments as it was easy to work out what a python script does. I gave them this challenge:-
(Before reading the answer I wonder if the Python experts on here can work out what it does?)

Code:

# SomeSound.py

audio=file('/dev/dsp', 'wb')
def main():
	for a in range(0,25,1):
		for b in range(15,112,1):
			for c in range(0,1,1):
				audio.write(chr(127+b)+chr(127+b)+chr(127+b)+chr(127+b)+chr(127-b)+chr(127-b)+chr(127-b)+chr(127-b))
		for b in range(112,15,-1):
			for c in range(0,1,1):
				audio.write(chr(127+b)+chr(127+b)+chr(127+b)+chr(127+b)+chr(127-b)+chr(127-b)+chr(127-b)+chr(127-b))
main()
audio.close()

The solution is here:-

NAME

       composite_midi - Default MIDI Implementation for Composite

DESCRIPTION

       The default MIDI implementation for Composite is a fixed MIDI implementation. Future versions of Composite will allow you to redefine the
       MIDI implementation, but a default MIDI Implementation will always be provided.

       This description of the MIDI implementation only covers the sampler plugin. At this time it does not apply to the composite-gui.
