A Python-based utility to consume a guitar tab and output a MIDI-style WAV using predefined samples.

Requirements

• pip install pydub
• pip install pygogo
• pip install future
• Not supported yet, but install ffmpeg / avconv to export to non-WAV format(s).

TODO

• Some sort of preliminary linter to make sure the tab data isn't complete garbage?
• No exceptions yet, so we're kind of working on the honor system.
• Only exports to WAV right now. :(
• Need a better way to determine double-digit notes or just really fast subsequent notes on the same line.

Sample Input

python tabsynthe.py -t tabs/tab1.txt -i bass -b 220 -c stereo
