5.Memory Management

Functions

imately 1/4 semitone—is achieved with a setting of 99. The detune effect is produced by simultaneously increasing the pitch of channel A while decreasing the pitch of channel B.

Use the DATA ENTRY control or -1/+1 switches to enter the data for this parameter. Once the DUAL MODE DETUNE function is called, subsequent presses on the A2 button increment the data value.

The memory management functions include functions for loading voices from the DX21’s internal ROM voice memory, for storing and loading RAM memory voices to and from cassette tape, initializing the voice memory, recalling voice data from a special “safety” buffer memory, and turning the DX21 memory write protect function ON and OFF.

A9: EDIT RECALL

In addition to the voice edit buffer, the DX21 has a special edit recall buffer memory which maintains the last edited voice data. If, after editing or creating a new voice, you inadvertently call new data into the voice edit buffer by pressing one of the voice selector buttons before storing the edited voice data, the voice you had spent so much time editing will be erased from the edit buffer. If only one error of this type has been made, the edited data still resides in the edit recall buffer and can be recalled into the voice edit buffer using this function.

When this function is initially called the LCD will read “Recall Edit ?". Confirm your intention to recall the data into the voice edit buffer by pressing the DATA ENTRY YES button. The DX21 will then reconfirm with “Are You Sure ?". Press the DATA ENTRY YES button again to actually execute the edit recall function. The EDIT mode will then be automatically entered, and the voice edit buffer will contain the data called from the edit recall buffer. Pressing another function button, a PLAY mode button or the EDIT mode button during the above process will abort the edit recall function.

A10: INIT VOICE

This function sets all voice parameters in the voice edit buffer to their “initialized” values, permitting voice programming from an effectively neutral set of values—a “clean slate”.
