Once some sounds are loaded, pressing each key will cause it’s loaded sound to be heard simultaneously.
Holding down the shift key while pressing the key will cause the sound to loop.
Dragging the volume and pan control up or down will raise or lower the volume of the sound, while dragging it left or right will pan the sound appropriately to the left or right speaker.
You may have as many keyboard windows open as you like.
The first sound played may take slightly longer to sound than usual. This is normal as Alphabet Soup starts up it’s sound playing threads. In a live performance situation, just remember to play a sound once during sound check before starting your performance.
Note: Remember that you must first make a specific keyboard window active before you can trigger sounds from that interface.
