Installing firmware update
Before even thinking about reflashing firmware over MIDI make sure you have a decent MIDI interface and MIDI on your computer is configured properly. MIDI implementation in Windows is a disaster anyway, but USB-over-MIDI (an unfortunate consequence of everyone using a laptop) only makes things worse. In case you have one of those dirt cheap Chinese USB to MIDI cables based on CH345 chip with the optocoupler left off to cut the costs by a few cents, you might be out of luck. Those cables are good enough for the simplest MIDI messages (NOTE ON, NOTE OFF) but fail with any messages longer than 3-4 bytes.

Here, 09 means the Electribe device is listening on MIDI Channel 10, so change your settings accordingly if needed. The response should be 15 bytes long, some digits could differ due to a different firmware version. Naturally any other MIDI monitoring tool can be used as well.
In case this procedure is not working please do not attempt to reflash the firmware and contact firstname.lastname@example.org.
Once MIDI connectivity has been set up you can proceed with downloading and installing firmware update. Everything required for this is handled by Electribe ER-1/ER-1mkII Flash Utility (erflash.exe):
Note. The installation only works on 64-bit Windows for now! So no bootcamp, Windows on some Mac/Linux partition or an ancient 32-bit laptop. Has to be a PC due to the fragility of MIDI timings for now, but macOS version is in works.
Flash Utility is a command line program that has to be executed in Windows command window (press Win + R keys, type cmd, press Enter). Always make sure that you do not have any other MIDI utility (eg. MIDI-OX, Bome etc.) running at the same time, as MIDI ports are not shared. Make sure your Electribe is listening on MIDI channel 10 for the Installer utility to work. Finally, make sure that SysEx is enabled on your device. Either an ‘o‘ is flashing in the rightmost column of MIDI/MIDI FILTER menu (see ‘MIDI filter settings’ in Electribe ER-1 Owner’s Manual) or MIDI/DUMP menu option is selected when starting installation.
Navigate to the directory where you downloaded erflash.exe. Type erflash /firmware. The screen will look like this:
To validate successful reflashing turn your Electribe on while pressing and holding SHIFT button. Factory firmware version is displayed. Turn off the device and turn it on while pressing and holding PATTERN SET button. Now, Electribe Shaman Firmware update version is displayed. In case the display reads 3-F you still have the factory firmware. Pressing STEP16 resumes normal operation.
Loading Custom Samples
Before you start, turn Memory Protect OFF on your Electribe (GLOBAL > PROTECT > oFF). In Windows command window navigate to the directory where you downloaded erflash.exe. Type erflash /samples. The screen will look like this:
Reporting An Issue
Electribe ER-1/ER-1mkII Flash Utility has been tested and found working on several laptop and desktop computers running 64-bit Windows 10 with different USB-to-MIDi cables. Mac OSX version is under development. Due to some idiosyncrasies in Windows MIDI implementation (limited buffer size etc.) as well as crippled USB cables, MIDI operations might occasionally fail. In those cases press Ctrl-C to cancel and repeat the whole procedure. Be extra careful during reflashing, those situations are clearly identified by CAUTION! prompts. However, in the unlikely event that something unexpected occurs, please report this immediately via email.
Please prepare the following information:
- Date and time of the incident (helps to link this with logs on server);
- Windows version and type of the computer;
- MIDI cable type (direct MIDI cable, USB-to-MIDI cable; for the latter, a snapshot of the cable would help);
- Serial number of the device (license code is NOT required);
- Screenshot of the command window (similar to the one above) or the session copy-pasted from the window;
- ER-1 Flash utility log file (erflash.log) that is created and stored in the working directory (the one where erflash.exe resides);
- Snapshot of the Electribe device showing the state of the display, LEDs and buttons after failure.
Additional narrative about the circumstances, what else was running on the computer etc. would also help.
