This chapter demonstrates the connection of an external line level signal to the DUAL FADER. The line signal can manipulate various modules of the synthesiser, for example, fluctuate the pitch of an oscillator. There are 3 points to connect an external line level devices to the system. They are two secondary inputs on the DUAL FADER A2 and B2 and on the left of the MATRIX in the NODE PROC.
Routing Functions of the DUAL FADER
Panner: connect only the left input and use both outputs.
Crossfader: connect to both inputs and one output.
Ducker: connect to both inputs and both outputs.
The DUAL FADER applies a RMS curve to crossfading and panning. This is demonstrated by connecting an oscillator to input one and sending output to either the left channel, or right channel. The mid-point of fader is 3bB louder because mixer curves are not linear, they are RMS (Root Mean Squared) curves, or equal loudness curves. The DUAL FADER utilises a RMS curve when used as a VCA. In the Hordijk system, there are several VCAs exponential curves in the filters, VCA’s in NODE PROC’s and 2 RMS curves in the DUAL FADER.
