15. TotalMix: Routing and Monitoring
The Hammerfall DSP system includes a powerful digital real-time mixer. RME's unique
TotalMix technology allows for nearly unlimited mixing and routing with all inputs and playback
channels simultaneously.
Here are some typical applications for TotalMix:
setting up delay-free submixes (headphone mixes)
unlimited routing of inputs and outputs (free utilisation, patchbay function)
distributing signals to several outputs at a time
simultaneous playback of different programs over only one stereo channel
mixing of the input signal to the playback signal (complete ASIO Direct Monitoring)
integration of external devices (effects etc). in real-time
mixdown of three ADAT inputs to one (realizing two additional inputs)
On page 42 you'll find a block diagram of the TotalMix mixer of the Multiface. It can help to
understand the basic signal flow and routing. It shows that the record signal always stays un-
altered, but can be passed on as often as desired, even with different levels. The level meter of
inputs and playback channels are connected pre-fader (due to the enormous routing
capabilities). The level meters of the hardware's outputs are connected post-fader.
15.1 Elements of the Surface
The visible design of the mixer is mainly determined by the architecture of the HDSP system:
Upper row: hardware inputs. The level shown is that of the input signal, i. e. Fader
independent. Per fader and routing window, any input channel can be routed and mixed to
any hardware output (third row).
Middle row: playback channels (playback tracks of the software). Per fader and routing
window, any playback channel can be routed and mixed to any hardware output (third row).
Lower row: hardware outputs. Because they refer to the output of a subgroup, the level can
only be attenuated here (in order to avoid overloads), routing is not possible. This row has
two additional channels, the analog outputs.
Every single channel has various elements:
Input and playback channels each have a mute and solo button.
Below each there is the panpot, realized as indicator bar (L/R) in order to save space.
In the window below this, the present level is displayed in RMS or Peak, being
updated about every half a second. Overs are indicated here by an additional red dot.
Then comes the fader with a levelmeter. The meter shows both peak values (zero
attack, 1 sample is enough for displaying full scale) by means of a yellow line and
mathematically correct RMS values by means of a green bar. The RMS display has a
relatively slow time constant, so that it shows the average loudness quite well.
Below the fader, the current gain and panorama values are shown.
The white area shows the channel name, the black area shows the current routing
target.
