Automation 125 yourself running out of memory, you can download unused AUTOMIX memories to a storage device, such as a MIDI data filer, then clear the memories. You can also expand the available memory with 1Mbyte expansion kits (ME4M). You can install up to two of these kits in the 02R, resulting in a maximum memory size of 2.5Mbytes. What is the Current Buffer? The only automix program that can be recorded or played back is the current AUTOMIX buffer. When you perform edits to the current buffer, its previous state is saved in an undo buffer. You can always undo the last edit operation. Note: You cannot undo a STORE operation. Once you have confirmed the operation, the previous AUTOMIX memory contents have been overwritten. Digital Recording Console 02R User's Guide
