Conductive Labs no longer makes the MRCC 880.

What's new in 1.1.095

- Warning: this release changes the format of the MRCC’s USB Device name (if you were not already using the beta version) so it will undoubtedly mess up the naming in your DAW or MacOS Audio MIDI settings. See instructions below to clear old names from the OS so the new name(s) will be used. Features: - Number of simultaneous routes (per patch) allowed/saved/recalled has been increased from 50 to 255. - A number of routes counter was added to the top left corner of the Activity screen. The counter turns Red once the maximum number of routes is reached. Fixes: - MRCC MIDI Cntrl Port won’t save when greater than P06 (P07 through P12 would revert to “-” on power cycle). - Enhancements to MIDI buffering and SysEx message handling. For large SysEx transfers (>10k), we suggest halting other MIDI sources to remove merged data, just to be on the safe side. MRCC can process messages after a SysEx end of message (F7), but will not interrupt or mix a SysEx message with MIDI realtime messages. Enhancements to MRCC USB Device enumeration: - Multiple MRCCs will now be recognized as unique devices by Windows current MIDI API when each is assigned a unique name (set on MRCC Settings page 4/4). It’s allowed to leave one MRCC named the default name, or change each MRCC to have a name with a letter, e.g., MRCC-A, MRCC-B, etc. - MRCC “PC Name” (Settings page 4/4), which allows you to select an alternate USB device name for MRCC has been reworked to prevent a race condition that caused the original name to re-appear sometimes. - The name “MRCC” is also changed; trailing nulls were replaced by spaces. It might affect how the name appears in your software, unless you already changed the name using the “PC name” settings on Settings page 4/4. See instructions for clearing Windows USB device cache below. [...]
