Version 2.36:
- ASIO: Dynamic Channel Allocation Mode:
- Application requests for samplerate capabilities are
now answered even if the channels to be used are not known.
(Compatibility issue e.g. with JRiver Mediaplayer)
- Now compatible with Open-Source Cross-Platform
Audio API "Port Audio"
- Now compatibe with some applications who set a certain
clock source without setting the audio channels to be used
- ASIO: Update to cooperate with Seraph products beginning
from driver version v1.15
- Improved Recording-Drop-Out-Recovery with WDM Audio
- Improved IRQ Sharing Operation with system components of high
interrupt frequency
Version 2.32:
- First Public Release
- This Version does not support AES42 Mode 2 operation (Mic is
clock slave of Trace AES42)
- Limitited Multi-Client-Functionality: if you want to use
additional audio applications simulaneously with your ASIO application,
using the same card(s), please take care to start the ASIO application
first! Using two ASIO applications simultaneously on the same card(s) is
not possibly with this version.
- If you use several Trace Sound Systems with one computer,
please do not use different driver versions. First, uninstall older driver
versions - then install the new drivers with the same driver version.
- If you want to use your Trace Sound System together with
a Seraph Sound System, please follow these hints which describe,
which driver versions are properly work together:
- Trace Series til v2.33 with Seraph
Series til v1.12
- Trace Series beginning from v2.36 with
Seraph Serie beginning from 1.14
On Windows™ Vista / Windows 7 audio applications, who do not
use ASIO or WSAPI, are not able to set a certain samplerate or sample
format. Instead, sample rate and sample format is set in the advanced
settings of an audio device in the windows control panel. This leads to the
following:
- If the desired samplerate of an audio application is not
equal to the current set samplerate, a samplerate conversion with
possibly an audible loss of quality will be the result!
- When using an audio device of the sound system with the
samplreate x and additionally attempting to use another device but with
a samplerate y, an error message will appear, since the soundcard may
only be used with one samplerate at a time. Unlike Windows 2000/XP,
Windows Vista/7 undertakes no sample rate conversion in this case!
- In order to operate several devices with a certain
samplerate, this samplerate has to be set up in the advanced settings of
an audio device in the windows control panel for each device separately.
As concluded from the previous point – no device of the soundsystem
should be in use, or else a change will be rejected!
- If you want to set the sample format for the audio
devices, first start with the playback devices and afterwards with the
recording devices. Background: When you open the tab "Recording",
Vista/7 starts a recording with each recording device in the list to be
able to show the input levels. In this case your MARIAN Audio System is
in use with a certain sample rate! If you now change back to the tab
"Playback", Vista/7 wil not stop the recording and a change to different
sample rate for a playback device will fail.
Audio applications, who do not use ASIO, GSIF or direct WDM-Audio,
now communicate with Microsoft MME or Microsoft DirectSound drivers instead
of communicate with the MARIAN drivers directly. The Microsoft drivers in
turn communicate with the MARIAN drivers.
For audio applications, who use these Microsoft drivers, apply:
- They can playback simultaneously using one playback device.
The Microsoft Kernel Mixer mixes the playback signals of the applications
into one stereo stream and routes it to one physical output device. If
playback takes place with different samplerate, the Microsoft Kernel Mixer
converts the samplerate of the playback streams to the highest samperate
required.
Hint: You can improve the quality of this conversion! (See Control
Panel | Sounds and Audio Devices | Audio | Sound Playback | Advanced |
System Performance) - The described simultaneous playback of
different applications fails, if the output device is already in use by
ASIO, GSIF or direct WDM-Audio.
- The number of the available recording and playback devices is
limited:
- under Windows 2000 to 10 devices each (20 channels)
- under Windows XP to 32 devices each (64 channels)
This limitation applies to the number of all audio devices installed
in the system.
You can use ASIO or GSIF to walk around this limitation. - The
minimum possible latency is limited to app. 20..30ms through the Microsoft
Kernel Mixer architecture.
Use ASIO or GSIF to walk around this limitation. - Microsoft
DirectSound or Microsoft MME devices (MME via WDM-Audio) does not work
with the driver's options for start/stop synchronization. Activate the
options "Synchron" and "SyncBus Synchron" only, if you use ASIO or GSIF.
Else the entire WDM-Audio system may "freeze". This issue can not be
compensated by our software.
- Some audio applications show additional audio devices with
theirs names appended by "(3+4)" or "(5+6)". This is caused by an anomaly
of the Microsoft MME/DirectSound system. Please ignore these devices and
do not use them.
Software samplers and synthesizers normally supply MIDI output
devices for other audio applications who want to use the software sampler as
an instrument. If such an application starts, then normally this application
opens the MIDI output devices and this in turn causes the software sampler
to initialize its audio engine with the configured audio outputs.
THIS OCCURS EVEN IF YOU HAVE NOT STARTED THE SOFTWARE SAMPLER
APPLICATION.
In the described situation the software sampler and the other audio
application may conflict, if they use the same audio output. You can use the
Trace AES42 with different audio applications at the same time but never the
same output device simultaneously.
Therefore this hint:
- First start the software sampler/synthesizer and setup an
audio output device which will NOT be used by the other audio application.
Start the audio application (sequencer) afterwards.
- If you start an ASIO or GSIF application the first time, then
it will use the device "Trace AES42 1-2" for recording and playback.
The Windows Multimedia System also supplies a software synthesizer
called "Microsoft GS Wavetable SW Synth". This synthesizer has also a
MIDI output port with the same name. Since there is no explicit setup for
the output device, the "Microsoft GS Wavetable SW Synth" always uses the
standard playback device configured in "Control Panel | Sounds and
Multimedia | Audio".
