The EDIT button is an on/off switch with an associated LED. All operations as discussed so far assume that EDIT is off. When edit is on, individual note editing can be achieved in part mode, and the list of parts in a song can be edited in song mode. To exit EDIT mode, press EDIT again (the LED will turn off), or select PART or SONG, which automatically turns EDIT off.
Editing a PART
When EDIT is pressed while in PART mode (PART LED lit), individual MIDI events can be edited. The eight track buttons are used to select which track is being edited. Only one track can be edited at a time (only one track is lit at a time). The display now shows the MIDI information of the selected track as follows:
The first three digits are the beat number, followed by the sub-beat count (00-95), followed by the note value, followed by the note velocity (01-127), followed by the note's duration (in beats and sub-beats), followed by the note's MIDI channel (1-16). The cursor is under the beat number, indicating that it can be changed with the keypad or the +/- buttons. To access the other parameters, the page up and page down buttons are used. They move the cursor as shown in the following displays:
The cursor moves to the next parameter, and will "loop around" past the last parameter back to the first. The MIDI channel is the channel that the note is output on if the track's MIDI channel is assigned to UNCHANGED. If the track is assigned to a specific channel, the original channel number will be shown in parenthesis. The note's MIDI channel can still be changed, but no effect will be heard unless the track's MIDI channel is assigned to UNCHANGED (see MIDI CHANNEL).
Other MIDI information is displayed as follows: (This information will only be displayed if it has been entered into the sequence beforehand. See Adding An Event.) For pitch bend, the display includes the beat, the sub-beat, MIDI channel, and pitch bend amount. The pitch bend range is from -8191 to +8192. The page up and page down displays scroll as follows:
Pitch bend amounts can be entered with the keypad, but the only way to achieve negative numbers is to use the `-' button until negative numbers are reached, after which any keypad entry will be negative.
For after touch, the display includes the beat, sub-beat, MIDI channel, and after touch amount. The after touch range is from 0 to 127. The page up and page down displays scroll as follows:
For controllers, the display shows the beat, sub-beat, controller number, controller amount, and MIDI channel. The controller range is from 0 to 121. The controller amount range is from 0 to 127. The page up and page down displays scroll as follows:
For program changes, the display includes the beat, sub-beat, program change number, and MIDI channel. The program range is from 0 to 127. The page up and page down displays scroll as follows:
For system exclusive information, the number of parameters could be any value. Since this could contain a large amount of information, the page up and page down buttons continue to scroll the data through the display until the end is reached. The display includes the beat, sub-beat, and any system exclusive data, as follows:
Erasing an event
Any event being displayed can be erased by holding ERASE and pressing RECORD. Erasing an event removes it from the track, but does not alter the timing of the track. For example, removing a quarter note at the beginning of the track does not move everything else forward a quarter note.
Adding an event
An event can be added by using the COPY button. Pressing and holding COPY causes the following display:
Pressing the RECORD button will insert a note at the current beat location, with a note value of C3, a velocity of 64, and a duration of 1 beat. This note can then be edited as described above to any desired value. If something other than a note is desired to be inserted, the page up and page down buttons can be used to scroll through the other choices before pressing RECORD:
In the above choices, pressing RECORD will insert the displayed event at the current beat and with values of 0.
While in part EDIT, the fast forward and rewind buttons are used to advance and retreat respectively, through the list of MIDI events on the selected track. When the end of a track is reached, or if a track is empty, the display will read END OF TRACK. Playing a part while in part edit will play the part while continuing to display the events as they happen on the display.
