Automating Snapshots
Snapshot automation is a powerful method of
changing the reverb parameters without having
to individually automate each parameter.
To automate TL Space Snapshots:
1
Insert TL Space on a track.
2
Select Snapshot mode.
3
Load an IR into each Snapshot and make any
desired changes to specific TL Space controls.
4
Name each Snapshot as desired.
5
Click
Auto
.
6
Add Snapshot to the list of automated con-
trols.
7
Select
TL Space > Snapshot
from the automa-
tion menu for the track.
8
Select the Pencil tool.
9
Draw the desired automation. The names dis-
played in the automation track will match the
names entered for each Snapshot.
PCI Bus Contention
Large Pro Tools TDM systems running TL Space
TDM in conjunction with video capture and
playback or other PCI cards may encounter
–6042 errors. These errors are caused when the
Pro Tools DAE engine cannot transfer audio
track data from the computer to the Pro Tools
card over the PCI bus quickly enough. The error
typically occurs when TL Space attempts to use
the PCI bus to load impulses. PCI bus conten-
tion can be addressed with the following steps.
First, you may wish to locate more demanding
PCI cards on the main PCI bus rather than in an
expansion chassis. By locating the PCI cards
away from Pro Tools DSP cards, PCI contention
is typically reduced.
Secondly, assign more DSPs to the Pro Tools
Playback Engine. Open the Playback Engine di-
alog and increase the number of DSPs per the
Number of Voices.
If this does not resolve bus contention issues,
the PCI Throttle control can be adjusted up-
wards one step at a time until the –6042 errors
stop. For example, the default setting for a Mac-
intosh G5 system is 33% and it can be increased
in two steps to 100% until the bus contention is
resolved. As more PCI throttling is used,
TL Space will take longer to update the data on
the DSP chip(s) running TL Space.
The PCI Throttle control can be adjusted in Pref-
erences mode. This control offers the settings
shown in Table 6. Settings take effect immedi-
ately across all instances of TL Space.
Increasing the PCI throttle control will reduce
TL Space performance as PCI activity is reduced.

For most users, the PCI throttle control pro-
vides optimum performance at the default
setting and should not be adjusted.
