MIDI Implementation Data
4. MIDI Implementation Data
The information contained in this chapter is intended to assist experienced
programmers in developing software for use with the LXP-5.
LXP-5 System Exclusive (SysEx) implementation can be divided into two
basic categories: Data and Event Requests, and Data Transmit and Re-
ceive.
Data and Event Requests
Data Requests prompt the LXP-5 to transmit specified data. Event Requests
prompt the LXP-5 to store the data currently in the edit buffer to a specific
memory location (register), or to retrieve stored data and place it in the edit
buffer.
