Well, I was feeling kind of adventurous, so I thought I'd give this a try. The manual, page 21, describes a collection of SysEx messages that emulate the interaction of the user with the front panel buttons. In order to manually execute a Patch Recall, the user presses the Recall Button and then presses the Input button (1 through 12) corresponding to the patch to be recalled. So to recall Patch 5, the user presses Recall and then Input 5, thereby recalling patch 5. So what happens if we replicate that sequence with SysEx messages? Turns out, if we send one of the "bb" button press messages for the Recall Button (0x41), followed by a "bb" button press message for an Input button, e.g., Input 1 (0x20), the two SysEx commands stream to the Apache and sequentially emulate first pressing Recall and then pressing the Input number, resulting in a recall of the desired patch. So you can in fact recall a patch stored on the Apache using SysEx in this manner. The SysEx to recall the 12 locally stored patches is as follows -
Recall 01 - {F0 00 01 40 00 41 F7 F0 00 01 40 00 20 F7}
Recall 02 - {F0 00 01 40 00 41 F7 F0 00 01 40 00 21 F7}
Recall 03 - {F0 00 01 40 00 41 F7 F0 00 01 40 00 22 F7}
Recall 04 - {F0 00 01 40 00 41 F7 F0 00 01 40 00 23 F7}
Recall 05 - {F0 00 01 40 00 41 F7 F0 00 01 40 00 24 F7}
Recall 06 - {F0 00 01 40 00 41 F7 F0 00 01 40 00 25 F7}
Recall 07 - {F0 00 01 40 00 41 F7 F0 00 01 40 00 26 F7}
Recall 08 - {F0 00 01 40 00 41 F7 F0 00 01 40 00 27 F7}
Recall 09 - {F0 00 01 40 00 41 F7 F0 00 01 40 00 28 F7}
Recall 10 - {F0 00 01 40 00 41 F7 F0 00 01 40 00 29 F7}
Recall 11 - {F0 00 01 40 00 41 F7 F0 00 01 40 00 2A F7}
Recall 12 - {F0 00 01 40 00 41 F7 F0 00 01 40 00 2B F7}
This may not be news for some but I was happy to discover it. Enjoy!
