Creating a new project

Recording

CWB is saved in the new Wave-64 format.

64-bit CWB files

CWB files are RIFF files with multiple WAVE chunks. Therefore, CWB files in previous versions of

SONAR were subject to the same file size limitations of normal RIFF Wav files. This could potentially

result in a CWB file that failed to save because a chunk was too large.

SONAR will automatically use the Wave-64 format if a CWB file exceeds 2GB.

Wave-64 file extension

Wave-64 files have a .w64 extension associated with them. Whenever a Wave-64 file is written,

SONAR saves it with an extension of w64.

CWP file persistence for 64-bit sample offsets

The SONAR project file format supports writing 64-bit sample offsets for regions and clips. When a

project containing 64-bit sample times is detected, saving that project automatically rewrites it in this

new format.

Setting the MIDI timing resolution

Each SONAR project has a setting for the timing resolution, or timebase, that indicates the

resolution of MIDI data. This resolution is measured in ticks or pulses per quarter note and is often

abbreviated as PPQ. The default resolution is 960PPQ, which is accurate enough for most

applications. In this timebase, each quarter note is represented by 960 ticks, each eighth note by

480 ticks, each eighth-note triplet by 320 ticks, and so on.

In some projects you may need a different timebase. For example, if you wanted to use eighth-note

septuplets (7 eighth notes per quarter note) and represent them accurately, you would need to have

a timebase that is divisible by 7, such as 168PPQ. SONAR uses the timebase you choose for a

project to determine the range of tick values in the Now time.

To set the timebase for a project

1. Choose Options > Project and click the Clock tab.

2. Choose the timebase you want from the Ticks per Quarter Note list.

3. Click OK.

Note: 64-bit CWB files are incompatible with previous versions of SONAR.

Note: Projects that contain 64-bit sample times are incompatible with SONAR 6 and earlier.
