I need to play a MIDI sounds in Delphi. How can I achieve this? Do I need some library for playing them?
I've been using these components for ages:

They've hardly ever failed on me, and unlike many other specialized Delphi components that have been around for this long, this code is pretty much alive (updates and improvements added recently).
Nothing fancy, but it's easy to use, fast, and rock solid. If you plan to do serious midi stuff, you'll eventually end up using this.
