More and more artists are using Digital Audio Workstations onstage to enhance their show with backing tracks or loops. Whether they are running just a few tracks or a complete backing band, DAWs are an integral part of many shows.
One problem is that you need your hands for the performance, not for operating the DAW tracks. Not to mention the havoc it wreaks with your stage presence when you reach over to press keys on your computer keyboard on stage.
Using the pok BLE, you have remote foot-control of your DAW, which you can set up further away (even offstage).
You can free your hands and give a better performance while maintaining control of your DAW.
