The Trigger LED will flash upon the completion of a valid System Exclusive

message. The option to permanently store these parameters is the available,

using the previously described method. (see Parameter Storage, page 13)

When the envelope of the DS301 is triggered, a MIDI note is always sent. It is

however possible to disable this note sending function by programming a note

value of 0 (zero) as the send note number. Obviously this can only be

accomplished using System Exclusive Messages and not via a normal MIDI

keyboard.

A typical System Exclusive Dump (in Hex) is shown below.
