When I click on the arrows next to any of the percussion instruments (kick, snare, clap, etc.) no sound is played.
According to the BeatBox Pro tutorial, you should be able to do this.
Also, when I click on playback after selecting a kit and pattern, the syncronization is way off between the pattern and the vertical row of boxes moving across the screen as the pattern plays.
Anyone else have these issues and is there a fix for them?
