Software: LMMS (Linux MultiMedia Studio), 100% free music composition software for Linux
LMMS has seen big improvements since the 0.3 series. I was surprised to load it up and see more instruments and tools, a prettier interface, and a much more stable music creation system.
Of note are the Vestige VST plugin, which allows Windows VSTs to be used (I tested the Superwave P8 and it worked very well); the C64 SID emulator, Gameboy emulator, and SF2 (SoundFont) import.
I have been using ALSA instead of Jack and can report very low CPU usage and good sound quality.
Apologies for the handheld video!

This is a track put together in Linux using LMMS or Linux Multimedia Studio. All sounds are generated internally and LADSPA plugins are used for all processing.
