Easily attachable to the instrument body
MIDI device with two modes of operation:
String Mode
Controller Mode
Triggered with piezo
Maps MIDI pitch-bend
Discrete scale
Continuous scale
Legato
Relative* / Absolute

and onset detection
FUTURE WORKS
IMPROVEMENTS
KICKSTARTER
Piezo onset detection
Easily attachable
Evaluate the interaction
Target musicians looking for new ideas
Reduce latency
Better algorithm, circular buffers
Packaging
CONCLUSION
Can work for players who want to extend
their musical possibilities
May not work for all genres
Players need training with the controls
to master this new device
