There is one firmware beta that came out 1.0.6
Doesn't say it addresses any other lockup issues, but may be worth trying. It's here:
http://www.m-audio.com/index.php?do=support.drivers&f=904
Might solve the lockup problems after recording as the Release Notes mention pasted below. Maybe also during recording???
That's the question being asked.
My external powering experience is mostly with MT1 model. Rarely did plugging in/out external power make any difference to what the deck was already doing, but on just a few
unrepeatable occasions the deck (as I remember) shut down even with a fully charged internal battery.
Maybe MT2 also 'locks-up' in addition to sometimes shutting down?
Release Notes:
This readme covers MicroTrack II Firmware v1.0.6 BETA.
Several issues reported from the field have been fixed - THANK YOU to those who cooperated on uncovering these issues. Users should be aware that this is a BETA release and it is therefore possible that bugs may still be present in this release. Please continue to check back at the M-Audio website (
www.m-audio.com) for upcoming firmware releases.
============================================================
Release Notes:
- Dialog box "Reading media" now displayed during initial power-on when inserted media containing large mp3 format files cause time delay in boot process.
- Dialog box "Reading media" now displayed if the unit is handling (ff, r/w, initial playback) large mp3 format files and a time delay is necessary before the requested operation is carried out.
- Record timeline fixed in s/pdif mode.
- DMA on/off** can be toggled within > System Menu > to accommodate cards that do not support DMA- Updated German "About" Screen
- Made modification for improving the accuracy of marker placement.
============================================================
** Leaving the DMA setting at 'on' will yield proper results with most types of CF and Microdrive media. However, some media types may encounter issues and will benefit from changing the DMA setting. The DMA setting does not change the speed or quality of recordings, and only should need to be toggled if experiencing problems, such as unit lock-up after recording.
