Utility Functions
Although not on the utility mode job list, this function makes it
possible to clear and initialize all internal song and pattern memory
and reset all parameters in one single operation.
To initialize the QY20 memory, turn the power switch on while
holding the [OCT DOWN], [OCT UP] and [A
#

] keys simultane-
ously — then release the keys as soon as the initial power-on display
appears.
Since all data in the internal memory will be erased, make sure any
data you want to keep has been saved to an external data storage de-
vice (page 163) before initializing the memory.
