- * and Mixxx to recognize the control vinyls.

+ * - CH2
+ * - AUX

+ * Recording channels could be mapped to:
+ * - Post CH1 Fader
+ * - Post CH2 Fader
+ * - Cross Fader A
+ * - Cross Fader B
+ * - MIC
+ * - AUX
+ * - REC OUT
+ *

+ * If we map a channel to:
+ * - CH1 Control Tone PHONO
+ * - CH1 Control Tone LINE
+ * - CH2 Control Tone PHONO
+ * - CH2 Control Tone LINE
+ * it is silent.
+ * There is no signal even on other operating systems with official drivers.
+ * The signal appears only when a supported application is started.
+ * This needs to be investigated yet...
+ * (there is quite a lot communication on the USB in both directions)
