Circuit Bending

Bontempi Electronic Organ

Modifying this Bontempi portable organ was my first "circuit bending" project and gave this stuffy old organ from the seventies a fresh trash character.

The primitive technology is very inviting to benders, and I can only recommend starting off with such a (cheap) organ, particularly as a lot of bendings are possible. I modified my instrument as follows:

• Volume control for hihats
• 2 drum mode controls
• 1 volume control for chords
• 2 controls for vibrato
• 1 control for extreme downpitching
