This is firmware revision “Blue Ridge” is an enhanced version of 1.0.7, which is the latest official released operation system by Roland. This operation system update/upgrade requires two eprom chips.

Features:

• Volume knob changes are now interpolated as opposed to directly applied to the data, allowing for much smoother volume changes when using the knob

• Rhythm selection Bender Control is now reset when MIDI All parameter reset is received, and when MT-32 Active Sensing is not received. Displays will not change, even when a Display Change exclusive MIDI message is recognized, unless the current mode is Master Volume input mode.

• Fixes a bug related to specific values in uninitialized sram on startup causing the unit to act bizarre.
• Backed RAM modification to avoid MT-32 clearing the RAM after each restart.

Note:

• The modification requires, some soldering/DIY know-how.
• The Roland MT-32 is not for sale, only this update/upgrade.
• The eprom chips will be verified before shipping and professionally packaged in anti-static material.
• The two chips are located at IC 26 and IC 27.
• Some PCB revisions may not have IC sockets.
