Alesis QS8 – Firmware OS update Version 1.02

This is firmware update 1.02 and is the latest known official released operation system by Alesis in 1996. This operation system update/upgrade requires one eprom chip as revealed in the article`s photos and the chip will be labeled to help you locate the correct chip socket. For more info, please check below.


Features/improvements from earlier firmware to 1.02:

  • Fixed Mix UnCompare bug where when going out of compare in Mix mode all voices playing should be stopped, but they weren’t
  • Changed Program and Mix Channel RANGE when using keyboard note presses to set the range so that the Global Keyboard Transpose is taken into account.
  • Changed software so that its aftertouch would work with both REV C and REV E boards. This change resulted in a new source file PANEL7.SRC where the black aftertouched value is forced to the value H’FFFF.

And more…
