You can assign your most used samples to the keys A to Z.
Only one sample on one key.
ASSIGN SAMPLING TO KEY
Open window for the key assignment by click in menu FILE --> Assign .. samles....
Drag the sampling you vill use to the key you vill have it on.
Be sure to save the changes.
To delete a sample drag it to the trashcan.
A drawback is a slower start than normal jingles.
