Minor Update, Improved Tracker Output

Hello!

Time for another update.

• Fixed a bug in the tracker renderer (for PICO-8, TIC80 and FamiTracker) that makes the output much less chaotic
• Updated the example outputs. It now includes more output examples for trackers (2, 3 and 4 channels) and 3 different MIDI output variants for two songs.
• Added a figuration line renderer that makes it easier to test a figuration line separate with different progressions, instruments and voice leading settings
• Added shortcuts for Ctrl-C (copy), Ctrl-V (paste) and Ctrl-D (duplicate) in the treeviews
• Using shared tab indices for many of the tabbed controls

For the next update, I plan to create a video tutorial.

Bye!
