SAWStudio 3.9m - March 9, 2006



* The engine has been enhanced for tighter Live Mode operation with lower actual latency at the same buffer settings than before and perfect record sync positioning in all combinations of recording modes, using the Auto Loopback adjustment as well as automatic compensation for monitoring from Aux Sends assigned to devices and Aux-Send-Return device loops for using hardware processing gear. The engine now senses and adjusts in the following manner:

Normal recording direct from device- ins, while monitoring from an external mixer source, adjusts the record region sync position using the Auto Latency Adjust value only. Sync is not dependent on buffer latency size settings and therefore makes perfect recordings even on slow audio drivers and hardware. Overdubbing will be in perfect sync when monitoring playback from any bus out directly or from Aux-Send-Masters assigned to device outs. This mode uses an external mixer (or soundcard driver hardware mixer) to split the source signal and blend it with the playback signal from SAWStudio for headphone monitoring during recording.

Recording from mixer channels assigned to live device-ins, while monitoring direct from the SAWStudio virtual mixer source, adjusts the record region sync position using a combination of the Auto Latency Adjust value as well as the exact internal buffer latency present in the monitor chain. Recording from mixer channels with VST synths patched into the Pre Patch point, while monitoring direct from the SAWStudio virtual mixer source, adjusts the record region sync position using the exact internal buffer latency present in the monitor chain only. These modes require low latency buffer settings of 4 x 128 or lower to be useful for monitoring without distracting delays. The Out and In buffer sizes should be set the same. The In-buffer-count should be set to 4 or higher and will not add to the monitor latency. The Out-buffer-count does add to the monitor latency and should set as low as possible while still maintaining stable system operation. This does require good audio drivers and hardware. Only a few soundcards can do this in MME mode… many cards can do this using ASIO mode. Overdubbing will be in perfect sync, regardless of the monitor latency, when monitoring playback from any bus out directly or from Aux-Send-Masters assigned to device outs. The record signal is taken from the Pre Patch point when recording from mixer channel sources. The record signal will include the EQ and Dynamics section of the virtual mixer unless the Pre Patch point routing has been changed in the Mixer Menu Pre-Fx Patch Signal Flow option. You may monitor the Control Room signal from the main faders and freely use the Mute and Solo buttons without disturbing the recording. You may also use Pre or Pst Aux Sends to send monitor mixes to performers through headphones. Temporary playback override of the mixer channel device-in source assignments can be done by pressing the Shift-Key when you start playback. This will force all mixer channels to MT source for the duration of this playback so you can easily listen back to the recording without having to change your input assignments. When you are finished recording, you should then change all mixer channel source assignments to MT for normal editing and mixing operations.

A special Live Aux-Send-Return processing loop feature is designed into the engine to allow the use of hardware processing gear to be blended into the mix in perfect sync regardless of the latency buffer settings. This mode is automatically engaged when an Aux-Send-Master is assigned to an out-device and its corresponding Return is assigned to an in-device. This mode splits the engine and delays the out buffers while leaving the Aux-Send signals in original time, thereby allowing the normally delayed hardware processing data to arrive and mix into the playback in perfect time. This does not require low latency buffer settings, but it does however delay the normal playback signal, and therefore will add latency to Live Mode virtual monitoring. Only the Aux-Send-Return device pairs will be affected, therefore you may still use other aux sends as headphone monitors, as well as any other bus out. The record signals will all be properly adjusted to drop in perfect sync regardless of the added monitor delay. This mode is best suited for mix operations where hardware processing gear is desired in realtime. It is recommended that you do not assign Return channels to in-devices when using Live input channels for virtual monitoring, in order to obtain the lowest possible monitor latency.



* Fixed the ontop status of the overwrite/append msg box for the BuildMix dialog.

* Adjusted code for the MT, SF, Record, F-Mixer, and Z-Mixer views to properly re-display memory images when resizing with the Windows “Show Window Contents While Dragging” option ON.

* Added code to use an alternate query method needed for certain VST plugins to register themselves as a synth.

* Adjusted code to compensate for LoopBack Latency only on active Mixer Channel Device recording tracks. The engine now auto-senses the correct amount of adjustment required for each type of recording source on a track per track basis regardless of the combinations of Live, VST, MT or direct sources being used at the same time.

* The Live Aux-Send-Return slip devices delay adjustment feature has been fixed to allow for using hardware reverb or other processing gear in the Aux-Send-Return loop assigned to audio device ins and outs.

* The engine modifications have taken away the DWave option of using a 1 buffer latency setting, although the actual latency performance at 2 buffers is now the same as it was in the earlier engine at 1 buffer. If you have been using a 1 buffer DWave setting, change it to 2 buffers…latency should remain the same.

SAW is the acronym for Software Audio Workshop.

SAWStudio combines both high-tech virtual mixing and hard disk editing technologies into one power-packed application. The look and feel of a fully controllable console, coupled with an all new high powered 24-bit hard disk engine make this product one of the most intelligent choices for the serious audio professional.

The SAWStudio interface is a tightly woven mesh of a fully developed mixing console interface and a newly designed MultiTrack recording/editing interface. This design is truly aimed at emulating the look and feel of working in a typical hardware based studio environment, replacing the physical mixing console, MultiTrack recorder and outboard rack-effects gear all at the same time.

This product represents a revolutionary new approach to mixing and editing audio in a virtual environment, truly replacing hundreds of thousands of dollars worth of physical gear needed to perform the same functions.

SAWStudio offers incredible versatility, amazing speed, and best of all, an environment which inspires your freedom of creative expression. Audio professionals in every niche of the audio industry, including full-length motion picture sound design, music production, theater automation, high-end radio & TV broadcast production, and audio production for video and arcade game development presently use SAWStudio technology.
