About PatchMix DSP

PatchMix = Patchbay + Mixer
It's a simple concept. PatchMix is a patchbay for your computer, where any physical
input or output (analog, S/PDIF, ADAT) can be connected to any HOST input or output
(ASIO, WDM, WAVE). Strips = Inputs and Insert Sends = Outputs. That's the "Patch"
part of the name. Now add a simple mixer with two auxiliary sends and a bunch of
effects. This lets you hear zero-latency effects while recording, a feat that no plug-in
effect can match. It's a super-flexible patchbay first and a mixer second—PatchMix.
Too Much Power?
We included the PatchMix DSP mixer and powered effects because they allow you to do
things that you can't do with any other sound card. However...please do not be intimi-
dated by PatchMix, because you DON'T HAVE TO USE IT unless you want to. The
Product Default Session connects every input and output for you. Once this session is
selected, you can forget about PatchMix and use the Digital Audio System like any other
sound card without the hardware effects and flexible routing features. PatchMix was
never meant to replace the mixer of your recording application. It's forte is allowing you
to connect your hardware inputs and outputs to your software applications in a number
of useful ways. You may not need this additional power right away. Use PatchMix in the
background if you prefer, and come back to it whenever you're ready.

About ASIO

ASIO stands for Audio Stream In/Out and is a standard communication protocol
between audio software and a piece of audio hardware. The low latency made possible
by ASIO, for example, allows you to sing into a microphone and hear your voice going
through software and hardware effects with virtually no delay in the signal. The effects
of a low-latency ASIO driver make it ideal for use with Virtual Studio Technology (VST)
instruments, plug-ins, and all other software-based synthesizers.
IMPORTANT -> Activating ASIO
It is important to understand that ASIO inputs do not appear in Cubase or other host
applications until they are CREATED in PatchMix DSP. This allows you to dynamically
assign the 32 available ASIO channels according to your specific needs.

An Example:

Create a new strip from a physical source such as S/PDIF L/R.
1.
Next, right-click on the new strip's insert chain and select the Insert Send option.
2.
Choose an available host ASIO input.
3.
This S/PDIF L/R input should now be available to record in your ASIO application.
4.

ASIO Channels are STEREO!

ASIO channels are stereo, period. Even when you are recording a mono source such as a
microphone, the ASIO stream is stereo (with the mono signal on both channels). To
record a mono input, you simply set up a sequencer track as a mono track and use either
the left or right ASIO channel from PatchMix as the input for the track.
