The SysEx Librarian app/utility includes two different methods of calculating the checksum of a file. If, after a failed software attempt due to a speed related failure, the STORE LED does not blink when another firmware file has been sent, simply turn off the amp, then power-up again with the STORE SWITCH engaged and the CHANNEL SWITCH set to CH#1 (as before). Midi app/utility settings have been provided (above) which will prevent the firmware update file from being sent to the amp faster than it can be processed, avoiding any speed related failures. Any failures could only be due to either a corrupted file or because the file is being sent to the amp faster than it can be processed. If a software update fails, the STORE LED will remain illuminated until the amp begins receiving a firmware update file again. Software updates will take about 30 seconds to complete.Īfter performing a successful software update, the STORE LED will stop blinking, and the amplifier will return to its normal mode of operation. Upon receiving a firmware update file, the STORE LED will begin to blink steadily and will continue to blink during the update. The STORE LED will remain on, indicating the software update mode.Ĭhanging the amp’s Channel prior to sending the firmware update file will abort the Software update process, the STORE LED will turn off, and the amplifier will return to its normal mode of operation. To perform a Software update, the amp MUST be powered-up with the STORE SWITCH engaged AND the CHANNEL SWITCH set to CH#1. Output Timing & Delay Between Buffers = 192ms min.Īuto-Adjust Buffer Delays If Necessary = Off/UncheckedĪs with any piece of modern gear, it’s always a very good idea to BACKUP YOUR PRESETS BEFORE PERFORMING A SOFTWARE UPDATE! Low Level Output Buffers, Size = 256 & Num = 64 IMPORTANT!!! Midi app/utility settings are below for Software updates: Software updates should be performed with the amp in STANDBY, and the Midi THRU/OUT and MESA FT.SW. At this time, all JP-2Cs have shipped with the current Midi software but should an update become available, it will be posted as an attachment to this article. To perform a software update for your JP-2C, you’ll require a firmware update file (see attachment below), a computer, a Midi/USB Interface, and a Midi app/utility capable of sending and receiving Midi SysEx files (the two free ones that we recommend are SysEx Librarian by Mac users and Midi-OX via Windows). How can I update the MIDI software for my JP-2C? ![]()
