Enhancements

* Added the hooks to SAC. The SAC Link option is activated from within the SAWStudio app and once a connection link between SAWStudio and SAC has been established, you can now pass data in both directions for recording and playback with SAWStudio using internal shared memory buffers that completely bypass the Windows soundcard drivers. SAWStudio will automatically disconnect from the drivers and use the internal shared buffers to communicate with the outside world through the SAC engine.

The menu options are selected from within SAWStudio and show up as follows:

The Activate SAC Link option on the SAWStudio Options menu will establish the internal connection between the two programs. SAC and SAWStudio must both be running at the time, and when the connection is established, a SAC<–>LINK icon will appear in the left corner of the SAWStudio main titlebar.

The SAC Link Options option expands out to include these following choices:

The Export Mix Data To SAC option allows you to instantly transfer the main MT track and channel mix data directly to the SAC FOH console. This will also automatically preset each SAC console channel input source to point to the associated SAWStudio MT track. This option allows you to playback the SAWStudio MT tracks in a 1 to 1 configuration through the SAC console. You can then use the SAC Monitor mixers to setup separate performer mixes. SAWStudio will not play audio through its own driver devices while the SAC Link is active. You do not have to make any preference changes in SAWStudio… the buffer settings will be internally set to relax the SAWStudio cpu load and rely on SAC to handle the low latency performance. The internal link will adjust for SAWStudio playback buffer size changing and latency causing plugins and deliver a fixed data stream to SAC with no changes needed to your edl session in SAWStudio.

The Import Mix Data From SAC option allows you to instantly transfer the SAC FOH console setup directly into SAWStudio, including automatically creating a record template with all channel input assignments preset, ready for a live recording of the current SAC session. All that is needed after this option is activated is to Ctrl-Click the first track’s record button in the SAWStudio MT to open all record meters for all active SAC channels, already pre-assigned. Once again, SAWStudio completely bypasses the soundcard drivers and gathers its audio data directly from the SAC engine. This allows SAWStudio to perform the MT record operation with very little added cpu load on the system, and also relaxes the buffer settings to essentially coast along quietly in the background while SAC handles the low latency monitoring load.

The Input Chan Play Tap At SRC option selects the SAWStudio tap for sending its track data to SAC. This option sends the data from the SRC position at the top of the chan module just after the Mono section. Using this option means you are essentially sending the playback data directly from the wav files on each track with no added processing from the SAWStudio virtual console.

The Input Chan Play Tap At PRE-PATCH option selects the SAWStudio tap for sending its track data to SAC. This option sends the data from just after the PRE-PATCH position within the chan module. This option would allow VST Synths data to be passed onto SAC and the Pre-Patch position routing options within SAWStudio will still apply, so some signal processing from SAWStudio may be part of the signal chain before the data reaches SAC.

The Input Chan Play Tap At PST-FDR option selects the SAWStudio tap for sending its track data to SAC. This option sends the data from the bottom of the chan module, which includes all chan processing and automation. Very useful for show playback of pre-recorded tracks.

Once the SAC Link is initiated, the SAC input source options will expand to allow individual SAWStudio Mixer Chan selections instead of just the hardware device selections. You will see all SAWStudio label references for each channel in the list. You may select any Input Chan from SAWStudio or any Output Chan. Selecting an Output Chan allows you to maintain a complete mix in the SAWStudio environment and only use one stereo input chan in SAC to playback the entire 72 tracks from SAWStudio. Any Input Chan selection is subject to the above mentioned Tap points set in SAWStudio.

Likewise in SAWStudio, the record meter Input Zone will display the SAC channel list with the SAC labels. You may record from any SAC channel which will automatically adjust the record meter to mono or stereo based on the SAC source assignment. An added bonus here is that you now have the ability to record extra channels in your current SAWStudio version than is possible with SAWStudio alone. For instance… SAWStudio Lite allows up to 24 record meters which are normally connected to the 12 possible stereo hardware devices. Normally that translates to 12 stereo tracks or 24 mono tracks or any combination in between. But with SAC’s ability to handle 36 stereo devices, you would now have the ability to pass on up to 72 signals in any combination of mono/stereo to the 24 record meters. Therefore, you can now record up to 24 stereo tracks (48 channels worth of data) in Lite as long as you have that many channels of hardware devices connected to SAC.

* The H/S Hide/Show option has been activated on the Record Remote Transport. Left-Clicking in this zone will hide (minimize) SAWStudio and leave the transport visible on top of whatever is underneath. This can be used to control SAWStudio’s recording functions from inside SAC for instance. Clicking the zone again will restore SAWStudio to the screen.

* The Hide/Show option has also been added to the Control Track view. Right-Clicking in the Control Track Pyramid Options zone will hide (minimize) SAWStudio and leave the Control Track view visible on top of whatever is underneath. This can be used to control SAWStudio’s playback functions from inside SAC for instance. Right–Clicking the zone again will restore SAWStudio to the screen.

* Record Retake will now function while RecRdy mode is active.

Bug Fixes

* Fixed the illegal softedge correction routine to trap for region entries with bad file links. This solves the mysterious appearance of giant softedges that keep coming back even after they have been removed.

* Fixed the ASIO menu text display to properly display the 16 bit integer format.

* Fixed code to handle right-click options in the MultiTrack Label area even if the mouse button is held down for a time instead of released in a normal quick click operation.
