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.
