Each tab has its own Play/Stop button. Clicking on it toggles playback for that instrument. The Global tab Play button starts and stops the whole performance.
All instrument tabs also have volume and pan sliders that appear when you click on the speaker icon. You can adjust volume and pan through that. Just note that Tabla has 2 volume sliders: one for tabla (right-hand drum) and one for bayan/dagga (left hand drum). This allows for perfect customization of the balance between the drums.
