These are 8 bit samples often used with the first Amiga trackers of the late 80s and early 90s, like Ultimate Soundtracker. In original and updated formats.

Following the info found in [this other archive][other], I tried to accurately convert the original files to modern & self documenting formats (.wav or .aiff), so they can easily be used in modern DAWs or modern trackers, like

Preamble

I run a fair amount of *nix software on my Windows machine - not because it's easy, but because it has become apparent that this die-hard Mac user needs a more diverse portfolio (for personal reasons; I have successfully avoided Windows for my entire career to date). In fact, it's quite difficult compared to running the same software on macOS, which isn't too surprising since macOS is generally considered to be a member of the *nix family, while Windows is not.

This document contains a random bag of things that will cut you as you attempt to cross the streams, and also the occasional tip or trick.

Condensced wisdom

There are many choices of 'environments' for building / running things, such as: MSYS2, Cygwin, Anaconda, VCPKG, WSL. They can be used concurrently (with important caveats; keep reading), and the correct one to use for a given task likely depends on compatability requirements of the software you're making or using.
path handling is a mess (WSL purports to ease this pain some

iTerm2 - color 'ls' and other outputs for MacOS

That's right. For OS X and BSD's ls, the flag is -G. Many people customize the behavior of ls by replacing it with an alias that adds extra options. I have the following in my .bashrc, for example:

alias ls='LSCOLORS=gxfxcxdxbxexexabagacad /bin/ls -bFHGLOPW'

Besides enabling colors in general, this sets the LSCOLORS variable in order to change which ones ls uses.
