The Session

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, or 96kHz sample rates, but the effect processors are only available at the
44.1kHz or 48kHz rates. See
When you start a new PatchMix DSP Session, the first choice you make is to select the
sample rate. Once set, you can only easily switch between 44.1kHz and 48kHz. You
cannot switch between 44/48kHz and 96kHz. This is because the number of mixer
inputs and outs change significantly at the higher sample rate. In the case of such drastic
sample rate changes, you must start a new session.
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 either S/PDIF
input or the Sync Daughter Card (word clock). If the session is set at 44.1kHz or 48kHz
and the external source is coming in at 96kHz, the Sync Indicator will be extinguished
(off) but PatchMix will attempt to receive the external data. if the Sync Indicator is Off,
the two units are NOT sample locked and you should correct this condition to avoid
intermittent clicks in the audio.
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. See Pre Fader or Post
up to a maximum number determined by available DSP resources and available inputs.
