Here's one that took a while to make. I was able to build Csound v5 under Linux on an IBM mainframe Integrated Facility for Linux (IFL), thanks to an IBM developer program. Csound is back on the mainframe after not seeing such an architecture for probably 40 years. It runs pretty fast, but that's not the reason to build it on the platform. I just wanted to understand the challenges of moving to the s390x architecture, since I sell mainframes for a living, and most of my customers have Linux today. Today's version of June Gloom was converted from my source code to Csound input on my PC under Free Pascal, shipped to the mainframe as drum12.csd, then processed by Csound on the mainframe to create a .wav file. I brought that back to my PC to create an MP3 file and posted here. Download or Play it here. Subscribe here:

Here's a version made on a Linux implementation on Amazon's Web Services. Now that my preprocessor has been ported to open source Free Pascal, it was a snap to compile it on an Ubuntu Linux instance. Csound only needed a simple install. It's my first try at Linux. Next stop: RedHat under z/VM on an IBM IFL at their developer sandbox. Unfortunately, there's no port of Free Pascal that supports the z architecture or instruction set, and I'll have to build Csound myself. I think the latter will be easier than the former. I can do the preprocessor work on my desktop and ship the Csound source to the cloud for processing. Download or Play it here. Subscribe here:

No music today, just the source code. Trying to set up a cloud instance and need to put the source somewhere to wget it.

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. Download or Play it here. Subscribe here:
