Voice Output Assignments
Since Pro Tools has extensive mixing capabilities, it also allows tracks to be freely assigned to various
outputs for playback. The MMR/MMP units are designed to assign Pro Tools tracks directly to audio
output channels on the MMR/MMP unit on a one-to-one basis and do not follow the output mapping of
Pro Tools session. When editing material on Pro Tools for eventual playback on an MMR/MMP, it is best
to place the material on the track where it should play on the MMR/MMP. Track assignments can be
changed locally on the MMR/MMP and any track can be assigned to play out of any MMR/MMP channel
output, but the default assignment when loading a Session will be to the tracks as numbered in the Pro
Tools Session, not the voice assignment patching.
Restrictions When Using the Pro Tools Session Format
Both the TASCAM MMR-8/MMP-16 and Digidesign Pro Tools have features for which there is no
equivalent function in the other system. This leads to certain restrictions the user should be aware of when
moving material between these two systems.
Pull Up / Pull Down
ProTools only supports a Pull Up from 30fps and a Pull Down from 29.97fps. The MMR/MMP supports
these and other frame rates. If something other than the standard frame rates or the above mentioned pull-
up / pull-downs are set in a recording made on the MMR-8, the ProTools Session file created will not
save that property in the Session file since that format has no way to store this data.
Frame and Sample Rates in Tape Mode
When creating TapeMode ProTools projects, be sure to pick a supported frame rate/sample rate
combination (see above) before recording. Once the TapeMode Session file has been created,
altering the frame rate will cause the Session to be regarded as a regular Non-Destructive Session and not
a TapeMode Session. This is due to the fact that the Session format does not store sample based start
times, but frame based start times. TapeMode very much depends on the Project or Session start time,
which cannot be altered if TapeMode capability is to be retained.
Limitations on Number of Tracks
ProTools 4.2 supports a maximum of 43 tracks per Session. This track number limitation affects how
many times tracks may be unloaded on the MMR-8/MMP-16. Once the maximum number of tracks has
been reached the unit will no longer be able to unload tracks for that Session. Note that this will also
affect the Loop Mode (menu 211) when the Repeat w/Unload option is chosen. Once the unload limit is
reached, the transport will stop with an error message indicating that the maximum number of tracks has
been reached. The same restriction will prevent exporting WaveFrame Projects or OMF Compositions to
ProTools if the maximum number of channels is exceeded. A future software revision of the MMR/MMP
will use the alternate tracks feature of ProTools to permit unlimited unloading of tracks and eliminate this
restriction.
Session Start Time Restrictions
When recording additional audio on existing projects created originally with ProTools, audio punch-in
before the start time defined in the project is not allowed. Pro Tools has the same restriction. If it is
necessary to punch in on a track before the Session start time, use the Pro Tools system to re-set the
session start time as appropriate. The MMR-8 has no provision to set the start time, except for tape mode.
Non-TapeMode ProTools sessions generated on the MMR-8 always use a start time of 0 and hence will
have no punch in restriction. A TapeMode project has its own TapeMode start time for all formats, set in
menu 230.
