Which file?

File | Choose this if… | Voices -- | -- | -- MORPHASE_v1.0.bin | You play a DIN MIDI keyboard through a Unit MIDI | 12 MORPHASE_BLE_v1.0.bin | You also want to play over Bluetooth MIDI (iPhone / iPad / Mac / PC), or don't have a Unit MIDI | 10

Pick one. Patch files work on both.

Install

• M5Burner (web): open the page for your build and flash it from the browser
  • Standard: https://burner.m5stack.com/2TERQX
  • BLE: https://burner.m5stack.com/GH5ZSE
• Launcher FW: copy the .bin to the root of the SD card and flash it from the file browser (OTA may not list MORPHASE yet)
• Other tools: the .bin is a single merged image; write it at offset 0x0

On first start, 32 factory patches are written to the microSD card (a few seconds).

You need

• M5Stack Cardputer ADV (the original Cardputer is not supported)
• A MIDI keyboard + Unit MIDI (DIP = BYPASS, Grove 5V = 5VOUT), or a Bluetooth MIDI app on the BLE build
• A microSD card, and earphones
