Sequential Circuits MULTI TRAK Firmware Latest OS G5 Update Upgrade Eprom for Multitrak

This firmware update is based on version 2.2 which was not the latest official released operation system by Sequential Circuits (SCI), but the most common. Latest version was 3.0 and has different SRAM configuration and a slightly different memory map. This operation system update/upgrade requires one eprom.

How to check current version:

Press both "MIDI Channel" and "MIDI Mode" at the same time.

Features/improvements:

• Synth voices can now be freely toggled ON/OFF, in sequencer mode (even when it is running, which brings a lot of options for "jam" use), in unison mode (to make 1-5 voices unisons instead of 6), or even in poly mode (although not very useful because the voices are still assigned).
• "To Tape + track 1-6": Disable the corresponding voice, it really is a forced "note off" because the release stage is still played if the voice was sounding.
• "From Tape + track 1-6": Re-enable the corresponding voice, the next assigned note can play again.
• Pitch bender routing can now be changed from VCO to VCF:
• "To Tape + Auto-Correct": Switch to Bender -> VCF.
• "From Tape + Auto-Correct": Return to Bender -> VCO (boot default).
• Disabled sending the sequencer notes to the MIDI output in "local off" mode ("MIDI channel + 9" to toggle it), allowing clean control of an external synth with the keyboard at the same time as the sequencer runs.

Note:

• Fully verified before shipping and professionally packaged in anti-static material.
• This will not work for device, which is pre-fitted with 3.0.
