Using the EZbus USB Audio Driver within Sonar 2.0

In order to record in 24-bit resolution within Sonar 2.0, a change must be made to the Sonar AUD.INI file.

Go to Start > Search > Files or Folders. In the Name category, type in AUD.INI and search your local C drive. Once the AUD.INI file is found, open the file by double-clicking it. It will open in the Windows text editor. Once opened, scroll down until you see:

Use24BitExtensible=0

You need to change the 0 in the line to a 1 so that it looks as follows:

Use24BitExtensible=1

Exit the text editor application saving all changes. Now open Sonar and go to Options > Audio. You will now be able to change the Audio Driver Bit Depth and the File Bit Depth from 16 to 24.

This fix also allows you to use the WDM driver within Sonar 2.0. Within Sonar, go to Options > Audio > Advanced. Uncheck the box labeled: Use MME Interface Even When WDM Drivers Are Present.

Using the EZbus USB Audio Driver within Sonar 1.3 (Skip the above mentioned fix to the aud.ini file.)

Launch Sonar, and go to Options > Audio. Select the General tab. Select EZbus as the Playback/Record Timing Master. Select 16 as the Audio Driver Bit Depth and File Bit Depth.



Select the Advanced tab.

Place a check mark next to Always Use MME Interface, Even When WDM Drivers Are Available.

Select the Drivers tab. Select EZbus (Win Me) or USB Audio Interface (Win 98 SE, Win 2000, Win XP) as the Input/Output Drive.

Select the Driver Profiles tab. Select EZbus (Win ME) or USB Audio Interface (Win 98 SE, Win 2000, Win XP) in the Show Profile for: field. Be sure that there is not a check mark next to Access Driver In Mono field.

Setting up Sonar for use with the EZbus as a Software Control Surface

Windows Millennium and Windows XP users have the ability to send/receive MIDI information via the EZbus/computer USB port. Other operating system (Win 98 SE, Win 2000) users will need an additional MIDI interface installed and configured within Sonar to send/receive MIDI data to and from EZbus/Sonar.

Step One
Depress the Audio/Virtual button on the EZbus so the LED is unlit.

Step Two
Click on the "EZ" icon located within your Windows System Tray. Scroll up and select Profile Editor.

EZbus is now capable of controlling various Sonar parameters via MIDI.

Step Five
Open Sonar. Within Sonar, go to FILE > OPEN. Look In: C:\PROGRAM FILES\EVENT\EZBUS\CAKEWALK_SONAR
There are two Sonar Project Files to choose from. Choose the Sonar/EZbus default Project File that matches the Control Profile that you downloaded to your EZbus.

Each default Project File has the main stereo mix bus output routed to the EZbus via USB. These two default Project Files also have various parameters within Sonar mapped to the EZbus faders, knobs, jog/shuttle wheel, etc.

Step Six
After opening a default Project File within Sonar, go to OPTIONS > MIDI DEVICES. Select the EZbus USB MIDI driver, as shown in the diagram below.



Most of the functions within Sonar's Console View can be controlled via the EZbus front panel. To view the Console View within Sonar, go to VIEW > CONSOLE.

Consult the chart below to view the default EZbus/Sonar Control Surface mapping. Note that you can change the parameter mapping using the Profile Editor application.

Using the EZbus Transport Control with Sonar

Step One
Press the Audio/Virtual button on the EZbus front panel to put the EZbus into Virtual Mode (the LED will be off).

Step Two (Win 98 SE and 2000)
Press the V5 button on the EZbus to select the Sonar profile. Note that Win 98 SE and Win 2000 users can only use the default profile that is resident in the machine.

Step Two (Win ME and XP)
Win ME and Win XP users can use the EZbus Profile Editor to send either of the two Sonar profiles (accessed via the EZbus Tray Menu) to the EZbus. These profiles will show up in the EZbus under the V1 button.

Step Four (All Windows Systems)
The EZbus LCD should now read:

Audio Channels 1-8
Volume + Pan + Mute + Solo

Step Five
Launch Sonar, and go to Options > MIDI devices. Select EZbus as the MIDI input/output device. Win 98 SE and Win 2000 users need to select the MIDI interface they have installed and configured to use with Sonar (not the EZbus MIDI I/O).




Step Five
Go to Options > Keybindings.

Click in the small circle (the radio button) next to MIDI and next to Key. Place a check mark next to Enabled. Use your mouse to select any MIDI note in the Key window.

Continue to bind each of the EZbus transport controls to the corresponding Sonar Function in the same manner.
