    Third-Party MIDI Spec

    Wait! I'm seeing the "0x64" error message when I send a Tempo Tap command as well The Temp Tap command still does it's thing (help in setting the tempo), but still the error message response is sent back. Wacky!

    I too am seeing this error message when I send a valid Tuner On/Off command. The tuner goes On or Off in response to my commands, but the "0x64" error message is also being sent back. Other commands I send don't result in an "0x64" error message. Is there something funky with the current...

    So far, the only bug I've found in firmware v1.15 is that if you switch the Preset via the AF3 front panel, then use MIDI to change the Scene, occasionally the AF3 doesn't give you a SET/GET SCENE (COMMAND 0CH) back, as it normally does. But I haven't dived in to Looper functions much. I'm...

    Checksum: Yes, it's the same as for the II. Very simple: XOR all the bytes in your midi message before and up to the checksum byte. AND that value with 0x7F, and boom, there's your checksum.

    Ah HA! You lead me to the problem. I was preparing an answer for you, documenting my meticulous checksum-generation algorithm, providing my SysEx commands and responses received from Axe-FX III, and mentioning Axe-FX III's firmware version just to be... ...Whaaaaa? Oops, I still had 1.12...

    Third-Party MIDI Spec

    Has anyone tried sending the query commands listed in doc with success? When I send Get Scene, Query Patch Name, or Query Scene Name via the old fashioned hardware MIDI port, I get an "0x64" error response back from the Axe-FX III.
