You can use the DDS 2 module to process an external audio signal:
- Connect an external audio source to the audio input on the rear side of the Super 6 by using a stereo 1/4 inch jack.
- Press down a key or enable HOLD.
- Turn the MIX control fully clockwise so that only the audio signal of DDS 2 can be heard.
- Turn the RANGE control to the leftmost position labelled LFO.
- Toggle DDS 2's mode switch to the upper position next to which it says AUDIO IN.
- If you still hear an audio signal in addition to the external audio signal, make sure that the output signal from LFO 1 in HF TRK mode is not sent to the audio channel of DDS 2. When LFO 1 is in HF TRK mode and the mode toggle switch is set to DDS 2, the signal from LFO 1 will be mixed with the external audio signal that the Super 6 receives via the audio channel of DDS 2.
Note: When you feed an audio signal into the signal path of the Super 6, it will trigger a gate signal as soon as it passes a certain threshold level, unless you select POLY 2 in the voice assign section.
As you may have noticed, these settings enable DDS 2's LFO mode. In this mode, the DDS 2 audio signal is bypassed to make way for an external audio signal that is routed into the mixer via the DDS 2 channel.
The MIX control allows you to control the balance between the audio signals from DDS 1 and an external audio source. In the mixer section, the external audio signal simply replaces that of DDS 2. After the mixer, the external audio signal is passed through the voltage controlled filter (VCF), the voltage controlled amplifier (VCA) and the effects section, all of which allow you to further modify the incoming signal.
You can also adjust the input gain of an external audio signal:
- Press and hold SHIFT and turn the MIX control to adjust the input gain.
- Return to editing your sound by releasing the SHIFT button.
If you don't manually adjust the input gain, the input gain level will default to a line input level that will make an external audio signal as loud as the Super 6's oscillator signals.
The audio input also features a gate trigger detector so that the envelopes and LFO 1 in reset mode are triggered when an incoming audio signal reaches a threshold determined by the input gain level. The LED to the left of envelope 1 indicates when an external audio signal passes the threshold. It lights up every time a trigger pulse is received.
