Firmware discontinued
The manufacturer has stopped releasing firmware updates for this device. Last known version: 2.3.
You can still add it to your rig to keep an inventory and track its used market price.
Update via MIDI SysEx. Download the Biscuit firmware (a zipped .syx file) from otomachines.com/support/, unzip, connect Biscuit MIDI IN to a computer MIDI interface, then send the .syx file using a SysEx-capable tool — SysEx Librarian (Mac) or MIDI-OX (Windows). Refer to the Biscuit Upgrade Procedure PDF on the same support page. OTO also publishes Der OTO as an alternate firmware mask for Biscuit with a different sound engine — see the Biscuit Der OTO section on the support page.
