Alesis MMT-8 OS v1.11 System Firmware Upgrade EPROM KIT
  • This upgrade version v1.11 is the latest update released by Alesis for the MMT-8
  • The included upgrade will be programmed to 1 new ATMEL EPROM chip, recently manufactured to ensure data integrity well past our natural lifetime.
  • I do not use 35+ years old UV EPROMS that are prone to bit rot, a major cause of data instability with vintage equipment of this era.

Keep in mind that the MMT-8 itself is not for sale, only the EPROM upgrade chip will be supplied.

Unlike some others, No used or refurbished as “new” components will be supplied here.

  • From Alesis’ update documentation: If an empty part is selected, Edit mode should not be able to be entered. However, if an empty part is played, it is possible to enter Edit mode, stop playing, and then insert events, which will corrupt data. Now, Edit mode cannot be selected when playing an empty part.
  • If an empty part is recorded for 683 beats (either by recording through the entire part, or rewinding with loop on to a beat before 683 and punching in) without having set the length first, the length of the part will not be set properly, causing erroneous data in the Edit mode as well as other problems. This is now fixed.
  • If a part's length is changed from the top, any notes whose duration was a multiple of 256 clocks (2beats/64sub-beats, 5/32, 8/00, etc.) will have its duration altered such that the duration becomes 256 clocks (2/64) greater than it was previously. This is now fixed.

If requested - A link will be e-mailed to you with the MMT-8 service manual for your own personal reference. I find this to be quite useful and informative

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.
