3. Control Panel under Windows
This chapter describes the MAYA22 USB Control Panel under Windows.
To open the control panel double click on the ESI icon in the task notification
area. The following dialog will appear:
The panel has the following functions and sections:
INPUT section: this section controls the input monitoring volume of the incoming signal from the
hardware. A pair of mono faders can be controlled together or individually depending on your
mouse position – perfect for stereo signals. The Mute button the channel allows you to mute the
signal. A red Mute button indicates that the mute function is enabled. When disabled, the button is
gray.
OUTPUT section: this section controls the playback volume of the playback signal from your audio
applications. The pair of mono faders can be controlled together or individually depending on your
mouse position – perfect for stereo signals. The Mute button the channel allows you to mute
playback. A red Mute button indicates that the mute function is enabled. When disabled, the button
is gray.
3.1 Input Selection
With the buttons on the left side, you can select the line input (Line In), the microphone input (Mic),
the instrument input (Hi-Z) or simultaneous recording of microphone and instrument signals (Mic
Hi.Z) via the corresponding button. When Mic Hi-Z is selected, the microphone input signal will be
recorded on the left input channel 1 and the instrument signal on the right input channel 2.
3.2 Input Monitoring
The Mon button (located between INPUT and OUTPUT) allows you to enable realtime input
monitoring. Once enabled all incoming signals are audible through the output. You can control the
input monitor level, the input level and the output level with the faders in the control panel.

3.3 Latency settings
Via Config > Latency in the Control Panel it is possible to change the latency setting (also called
“buffer size”) for the driver of MAYA22 USB. A smaller latency is the result of a smaller buffer
size. Depending on the typical application (e.g. for playback of software synthesizers) a smaller
latency is an advantage. At the same time, the best latency setting indirectly depends on the
performance of your system. For recording applications, a typical latency buffer size between 4 and
8ms is standard. Note that the latency has to be setup before launching the audio application using
MAYA22 USB.
3.3 DirectWIRE
What is DirectWIRE?
DirectWIRE is a driver technology, developed by ESI, which can be used for routing audio streams
internally within applications using EWDM Audio MIDI Drivers exclusively developed by ESI.
With the DirectWIRE router, an application can record from other application’s audio outputs
without external wiring or any loss of data when they are running at the same time.
DirectWIRE also allows you to easily rip any audio stream in real time by transferring data thru
DirectWIRE from MP3s, live On-line Broadcast and On-demand content, and more.
DirectWIRE is not available under Mac OS X.
DirectWIRE Panel
Click on DirectWIRE on the MAYA22 USB control panel. The DirectWIRE dialog as shown below
will appear. DirectWIRE digital virtual wiring technology, developed by ESI, routes audio streams
internally within applications using standard audio drivers such as WDM, ASIO and MME, even
when they are running at the same time.
The number on the row represents the input or output port. The columns represent ins and outs (on
and off) of the respected drivers. Patch the virtual cables from one point to another as you drag your
mouse point.
INPUT section: It's used to route signals from the card's hardware inputs.
MME section represents general application's I/O: Ex.) WinAmp, WaveLab (non ASIO mode),
Cakewalk, Audition, Vegas, etc.
WDM section represents Multi-MME application’s I/O: Ex.) SONAR (when using WDM/KS),
PowerDVD, WinDVD, etc.
10
ESI MAYA22 USB
ASIO section represents ASIO application’s I/O: Ex.) Cubase, Logic, Reason, Nuendo, SONAR
(when using ASIO), Samplitude, etc.
GSIF section represents GSIF application like GigaStudio.
Note that some applications support multiple driver modes.
DirectWIRE Examples
Example 1. Recording from WinAmp (MME) to WaveLab (MME).
If you want to record what's played back in WinAmp, but don't want to hear the sound, you should
click the OUT button in the MME section so it'll change to OFF.
Example 2. Recording from WinAmp (MME) to
SONAR (WDM).
Example 4. Recording from GigaStudio (GSIF) to
SONAR (WDM).
Example 3. Recording from WinAmp (MME) to
Cubase, Logic, Nuendo (ASIO).
Example 5. Recording from GigaStudio (GSIF) to
Cubase (ASIO).
