4 - The PatchMix DSP Mixer<br />
The Session<br />
The Session<br />
The current state of the PatchMix DSP mixer (fader settings, effects routings…everything!)<br />
can be saved as a Session. Whenever you create or modify a mixer setup, all you<br />
have to do is Save it to be able to recall it at a later time.<br />
Before you begin using PatchMix DSP, you need to set it up to be compatible with the<br />
other software applications you may be running. The most important consideration is<br />
your system sample rate. PatchMix DSP and any applications or other digital gear you<br />
are using must be set to the same sample rate. PatchMix DSP can run at 44.1kHz,<br />
48kHz, or 96kHz sample rates, but the effect processors are only available at the<br />
44.1kHz or 48kHz rates. See 96kHz Operation for complete details.<br />
When you start a new PatchMix DSP Session, the first choice you make is to select the<br />
sample rate. Once set, you can only easily switch between 44.1kHz and 48kHz. You<br />
cannot switch between 44/48kHz and 96kHz. This is because the number of mixer<br />
inputs and outs change significantly at the higher sample rate. In the case of such drastic<br />
sample rate changes, you must start a new session.<br />
You can also set up an external sync source, thereby obtaining the sample rate from<br />
some other device or application. External sync can be obtained from either S/PDIF<br />
input or the Sync Daughter Card (word clock). If the session is set at 44.1kHz or 48kHz<br />
and the external source is coming in at 96kHz, the Sync Indicator will be extinguished<br />
(off) but PatchMix will attempt to receive the external data. if the Sync Indicator is Off,<br />
the two units are NOT sample locked and you should correct this condition to avoid<br />
intermittent clicks in the audio.<br />
PatchMix DSP comes with several session templates to choose from so when you create<br />
a new session you can either create a “blank” session based around a designated sample<br />
rate, or select from a list of template starting points.<br />
In a PatchMix DSP session the number of strips in the mixer is dynamically configurable.<br />
See Pre Fader or Post Fader. This allows you to create only those strips you need<br />
up to a maximum number determined by available DSP resources and available inputs.<br />
New Session<br />
You create a new session by selecting “New” in the PatchMix DSP main Toolbar. The<br />
following dialog box appears.<br />
Name the<br />
New Session<br />
Select a Template or new<br />
Session at the desired<br />
sample rate<br />
Choose the location<br />
where the new Session<br />
will be saved.<br />
Add your own<br />
comment or note<br />
about the Session<br />
Important: When<br />
using any form of digital<br />
I/O, the digital devices<br />
must be synchronized to<br />
the same master clock.<br />
