Alesis QS6 OS v2.00 EPROM Firmware Upgrade KIT / New ROM Latest Update Chip with Service Manual

• This upgrade version 2.00 is the latest update released by Alesis for the QS6 synthesizer.
• Included will be 1 new EPROM chip to complete the upgrade.

The EPROM upgrade chip included in this listing is directlysourced from Alesis during my tenure as a repair technician. They are notcopies, which are programmed on to so-called “new” EPROM chips of questionablenature.

Please note that the QS6 itself is notfor sale, only the EPROM upgrade chip is.

• Below are a list of issues resolved in the 2.00 update:
• New Presets
• Fixed Card Sequence Overrun bug.
• Fixed - QS7/8 to QS6 sample remapping lookup table for QS7/8 Ethnic group entries 11-16.
• Fixed - bug where COMPARE and GLOBAL interact to defile Mixes (but not programs in PROGRAM mode).
• Fixed - FX config 5 bug in which if the Leslie input was reverb, a potentially random RAM value would be cleared.
• Modified portamento routine so that each sound retains the last note played in that sound, and glides from the last note to the new note played. Other sounds or channels will no longer cause portamento interaction.
• Fixed - Mix MIDI Dots bug where when leaving Edit mode by hitting the <MIX> button, no new MIDI Dots would light when a new key was pressed until all keys were first released.
• Fixed - Mix UnCompare bug where when going out of compare in Mix mode all voices playing should be stopped, but they weren't.
• Added - Baud Rate NACK sysex message (18h). The QS6 cannot change Baud Rates on its computer port like the QS7/8 can. Now, if the QS6 receives a "Change Baud Rate" message, it responds with the new Baud Rate NACK message (#18h). Before, it was sending a Baud Rate ACK message (#17h).
• Fixed - MIDI Bank Select bug where S6 card banks could not be called up through MIDI.
• Changed - Controller A Default Number to 12. Changed Controller B Default Number to 13.
• Controller 11 (MIDI Expression) is now implemented as another volume scaler like Controller 7 (MIDI Volume). This affected VOICE.SRC, DATA3, MIDISUBS.SRC and PAGESUBS.SRC.
• Fixed - bug where Controller A value was not being sent out the Computer Interface port correctly. It was, however, going out the regular MIDI OUT port correctly. This fix changed the file CONVS.SRC at the very end in the routine CTL_MIDI. Fixed bug (also in S8, S9) that kept drum sounds that were gated from being cut off when another note in the same mute group was played.
• Added - Card Sequencer from QS7/8. Only sequence numbers 00-49 are allowed.

If requested - A link will be e-mailedto you with the QS6 service manual for your own personal reference. I find thisto be quite useful and informative
