I installed the update, hoping my pet peave would be corrected. The upgrade actually made matters worse. I returned to the earlier version and am now back where I started, using workarounds. I love the Microbrute (especially since I started running the audio through a Werkstatt filter) and the workarounds are acceptable. But I sure hoped new firmware would fix things for me.
When the new firmware is installed the sequencer won't MIDI-sync to an external clock. I cycled through all settings, rebooted, did it again, no go. I launched the previous editor and it read the settings differently! I again cycled through settings, rebooted, etc. but things were still flaky and unpredictable. I returned to the new "control center" and reinstalled the upgrade, in case the install had gone wrong. After rebooting, everything was flaky again.
So I returned to firmware version 1.0.3.2 and everything settled back into predictable controllability. That's OK with me but I have to raise an eyebrow at Arturia's programmers.
