Sequential Circuits MAX OS 0.5 EPROM Firmware Upgrade KIT

  • This upgrade version 0.5 is final known operating system firmware issued by Sequential Circuits for the MAX.
  • Included will be 1 upgrade chip to complete the upgrade.
  • All EPROM upgrade chips supplied here are brand new, recently manufactured and sourced direct from ATMEL to ensure data integrity well past our natural lifetime.

Keep in mind that the MAX itself is not for sale, only the EPROM upgrade chips will be supplied.

  • The following 0.5 firmware upgrade offers general system code optimizations, improved MIDI compatibility and resolves an issue with MIDI CC when MIDI mode 4 is selected, only two of the voice timbres would respond to CC values.
  • Lastly, I suggest that you search and have a look at the great hardware mod and upgrades that Tauntek is working on for the MAX. Absolutely astounding work!

Be sure to take note of the marked orientation notch on the side of the EPROM to ensure correct installation. EPROMS inserted backwards will be destroyed. Incorrect insertion of ICs is also likely to cause damage to the board.

All EPROM upgrades have been prepared in an ESD-safe production environment and will be packaged in equally ESD-safe materials.
