Real-Time Interaction and Performance

INTRODUCTION

OddString turns the guitar/bass into an hybrid instrument

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

MOTIVATION & GOALS

To enhance/expand expression

To improve/simplify traditional controllers

Do not force players to modify technique too much

Because it is FUN!

++

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
