June Gloom #14

Here is the last version of June Gloom I will post. Today's run through the algorithm is a milepost of sorts. I finally was able to generate the whole thing without having to run either the preprocessor or Csound in that dreadful XP box on my Windows 7 laptop. Today I finished the port of the preprocessor to Free Pascal from Turbo Pascal. Most of the problems along the way were due to failing to check for Nil pointers and out of bounds arrays. Apparently Turbo Pascal circa 1989 let me do some bad things. I fixed those and the program compiled. After earlier porting the Csound code to a version of Csound that runs in Windows 7, I'm now free of the XP box. Today's post is the result. Nothing is substantively different, except it's another round through the algorithm, so everything has changed.

Here is one more version of the June Gloom piece I've been working on.

For the past eight years I've used an older version of Csound (4.19 from 2005) that only runs on Windows XP. I moved to a new version of Windows, and the old version stopped running. So I obtained a current version, Csound version (5.17.11 from May 2012). To my delight it worked with all my old opcodes with only minor problems with the install. This version of the piece was made with the Windows 7 version of Csound 5.17.11.

My preprocessor, written in Turbo Pascal (filedate 1989), is another story. Turbo Pascal won't work in the current version of Windows 7. I had to create a virtual machine running XP, and that is working, but poorly. All things considered, my $90 investment in Turbo Pascal was worth it, since I have been able to use it for 23 years.

My next task is to try to port the Turbo Pascal to Free Pascal. My first attempts resulted in code that compiles with minor changes, but fails at run time reporting memory issues. That conversion will take much longer.

June Gloom #11

This is another final version. The eleventh time through the track shows off the idea of several different instruments playing the melody, and each one can choose to trill, slide up, slide down, play only one note instead of all three, and many other variations. The conflict between the instruments makes for an interesting sound.
