Poly aftertouch events in Logic Pro
Poly(phonic) aftertouch events are generated by mechanical pressure sensors beneath
each individual key on some MIDI keyboards. The resulting sound modulation only affects
the particular note that is pressed harder (after the initial keystrike). Only a few keyboards
offer this capability.
Ch(annel): MIDI channel of an event from 1 to 16.

SysEx events in Logic Pro
System exclusive data (SysEx) is unique to individual MIDI devices. You can record
these events by using the dump utilities of your synthesizers, which let you save patch
information, or other data, outside the MIDI device (in a project or MIDI file).
You can choose whether SysEx data is displayed in the Status column in hexadecimal or
decimal format. You can view SysEx data as ASCII characters in the Length/Info column.
View SysEx data in hexadecimal format
In Logic Pro, choose View > SysEx in Hex Format.
View SysEx data as ASCII characters
In Logic Pro, click the Additional Info button.
The SysEx message is displayed in the Length/Info column. SysEx and EOX status bytes
are represented by Ⓢ and Ⓔ, respectively.
Edit SysEx Data
Warning: Editing SysEx events requires a thorough understanding of the data format
used by the MIDI device. Incorrect edits can lead to the corruption, or loss, of sound or
other data.
1. In Logic Pro, select a SysEx event in the event list.
2. Click the Additional Info button to view the SysEx message.
