7.7 MIDI System Exclusive Implementation
This chapter contains information to enable programmers to write software for the Fx 70. It contains de¬
finitions of all commands necessary to transmit or receive data via the MIDI interface.
Data transfer is only possible by MIDI when a MIDI channel has been set (OMNI, 1-16). With a MIDI
reception channel - - there is no communication via the MIDI interface (see Chapter 7.1).
