MOTIVATION & GOALS

To enhance/expand expression

To improve/simplify traditional controllers

Do not force players to modify technique too much

Because it is FUN!

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
