Troubleshooting
TRACKERpre Reference Manual 47
Simultaneous WDM/ASIO Playback (PC only)
The Tracker Pre USB 2.0 only supports playing back one stream format at a time on
the PC. Each of the two mentioned stream types has an associated priority. If a
higher priority stream type is opened while a lower priority stream is already
playing, the lower priority stream will stop playing. ASIO has the highest priority,
followed by WDM.
Tracker Pre USB 2.0 vs. USB 1.1 Operation (PC only)
The Tracker Pre can operate in either USB 2.0 or USB 1.1 modes on the PC. To use
the 88.2 kHz, 96 kHz, 176.4 kHz and 192 kHz sample rates, you must be operating
in USB 2.0 mode. The included E-MU USB Audio Control panel software includes
an indicator to let you know which mode the device is running in.
Tracker Pre USB 2.0 comes up in USB 1.1 mode (PC only)
To verify the USB operation mode (1.1 or 2.0), launch the E-Control application.
The USB mode being used is displayed in the lower part of the window.
• Your computer may contain both USB 1.1 and USB 2.0 ports. Try using the
USB ports on the rear of your computer.
• Always turn the power off to Tracker Pre using the front panel control before
connecting or disconnecting the USB cable. Hot-plugging the unit with the
power on can cause the Tracker Pre to power-up in USB 1.1 mode. If you see
the Windows message, “This device could perform faster…”, simply turn
power off, wait a few seconds, then turn power on again.
Using Tracker Pre with Older Versions of Emulator X/Proteus X
Tracker Pre will not function as a dongle for Emulator X or Proteus X software
versions below Ver. 2.5. If you have older versions of these products, you must
upgrade to 2.5 in order to use Tracker Pre as a dongle. Older versions of Proteus
XLE or Proteus VX will continue to operate normally.
