12.2 Bitwig Studio

Bitwig Studio is a DAW designed in Berlin with a live hands on philosophy to it. Along with its highly animated and intuitive graphic interface, it offers well designed clip-based and timeline arrangement paradigms for composing. The Bitwig designers have included a complete suite of powerful and great sounding native effects and digital instruments, with many performance and modulation features for many users, its the parameter modulators and their well designed routing system that makes it compelling to create music and sound design in BitWig.

Setting Up Sync in BitWig

As described in section 7.4, when you are using the Local Audio path, the buffer size and sample rate must be matched in both Spat Revolution and Bitwig Studio. In Spat you do this in the preferences and in Bitwig you do in the audio engine settings. If they don’t match at first, you may need write the correct settings to the preferences by quitting and restarting both applications to get the correct green sync status between the apps.

Setting Up Tracks in BitWig

One good way to work with Bitwig and Spat together, is to set Bitwig tracks to output their audio to Effect Track types - they are like Aux busses in other software you do that routing from an audio track output assignment settings.

Setting Up Spat SEND in BitWig

Put the Spat SEND plug-ins on individual Effect Tracks , enable the local audio path with THRU set to off, so all audio streams are rendered to output in Spat.

Like in all Local Path Audio workflows, you should see Spat SEND inputs appearing in the Spat Environment Setup graph which relate directly to the plug-ins hosted in the other software environment, reflecting their TrackName and channel count.

Spat Source Automation in BitWig

Now the fun starts - on the Bitwig Send tracks, which host the Spat SEND plugins, you will see all the parameters of Spat sources available as dials. Use the Bitwig ( + ) to open the Device Parameter Modulators and assign the many and varied modulation sources to control Azimuth, Distance or other Source Parameters.

Setting Up Controllers in BitWig

BitWig has comprehensive support for many popular MIDI controller surfaces. These can be very easily mapped to Spat SEND parameters for hands on control of virtual objects and rooms.

Clearing Shared Memory

Currently with Spat Revolution v1.1 some users have experienced an issue where Spat SEND and RETURN plug-ins are not cleared from RAM after using certain third-party hosts. BitWig is one of those. If this happens, Spat SEND and RETURN modules will appear in the Spat setup graph editor, when there is no host software running in the background. It can cause problems, when a host with plugins is launched and more SEND and RETURN plug-ins appear to be doubled.

The workaround, if this is happening with your particular 3rd party software, is to invoke a special debug action in the Spat setup editor. It is called Clean Shared Memory. It is available by right-clicking anywhere in the background of the signal graph editor. A pop-up menu will appear with various options and shortcuts. Scroll to the bottom and choose Help/Clean Shared Memory

If this command is executed, Spat and the plug-in host will then need to be restarted.
