The Session
The current state of the PatchMix DSP mixer (fader settings, effects routings…every-
thing!) can be saved as a Session. Whenever you create or modify a mixer setup, all you
have to do is Save it to be able to recall it at a later time.
Before you begin using PatchMix DSP, you need to set it up to be compatible with the
other software applications you may be running. The most important consideration is
your system sample rate. PatchMix DSP and any applications or other digital gear you
are using must be set to the same sample rate. PatchMix DSP can run at 44.1kHz,
48kHz, 88kHz, 96kHz, 176.4 kHz or 192kHz, but its complete set of features are only
available at 44.1kHz or 48kHz. See
“Using High Sample Rates” on page 111 for details.
Once the sample rate is set, you can only easily switch between 44.1k and 48k. You
cannot switch between 44/48k and 88k/96k/176k/192k. With a change to these
higher sample rates, you must start a new session.
Important: When
using any form of digital
input, you MUST
synchronize the Digital
Audio System to the
external digital device
(S/PDIF/ADAT).
You can also set up an external sync source, thereby obtaining the sample rate from
some other device or application. External sync can be obtained from the ADAT input
or S/PDIF input. If the session is set at 44.1kHz or 48kHz and the external source is
coming in at a higher rate (such as 96k), the Sync Indicator will be extinguished (off),
but PatchMix will attempt to receive the external data. The two units are NOT sample
locked however, and you should correct this condition to avoid intermittent clicks in
the audio. Always check for the presence of the LOCKED indicator whenever you are
using a digital interface.
PatchMix DSP comes with several session templates to choose from so when you create
a new session you can either create a “blank” session based around a designated
sample rate, or select from a list of template starting points.
In a PatchMix DSP session the number of strips in the mixer is dynamically config-
urable. This allows you to create only those strips you need up to a maximum number
determined by available DSP resources and available inputs.
New Session
You create a new session by clicking the “New Session” button in the PatchMix DSP
main Toolbar. The following dialog box appears.
