Tascam MMR-8 Release Note

TimeLine EDL Format Addendum 1.0

To support Version 3.0 of the MX-2424, some additions have been made to the

OpenTL specification.  With the way OpenTL rules are defined, and its parser

implemented, older parsers / implementations should have no problem

automatically dicarding the unknown attributes and continuing on with a good

read.  The additions described in this section only affect the project file.

1)  New Project Simple property attribute:  Tape Mode State

TPMD   Tape Mode State          Integer (0 = Off, 1 = On)

example:  TPMD(1)      -- TapeMode State requested to be on

2)  New Project complex value attribute: Virtual Track Table

    This new attribute must optionally be placed before the TrackList

    (TKLS) in the project file.  Track indexes used by the virtual tracks

    are always larger than the highest track supported by the generating

    device.  A new range of indexes is defined by the Virtual track table

    to represent tracks that are editable, but not playable. Therefore,

    this should not affect any prior compatibility. Previuos versions of

    OpenTL implementations from Tascam represented virtual tracks by using

    track indexes greater than or equal to 8192.  Those virtual tracks will

    remain virtual and non-editable (unless first explicitly loaded to

    another slot).  The table itself defines what index to start interpreting

    tracks as virtual and editable, and the number of supported virtual

    tracks (i.e. the max number of virtual tracks supported by the creator

    of the OpenTL file).  This defines the exact range of track indexes to be

    treated as virtual and editable.  For OpenTL files generated from Tascam

    products, the start index for the first virtual track index will be set to

    64, regardless of how many tracks that a given machine actually supports

    for playback.  That means for an MMR-8, indexes 8 through 63 will not be

    used; for an MX-2424, indexes 24 through 63 will not be used. This may

    change in the future, but not in the near future (only when a product that

    records and plays more than 64 tracks is developed).
