Installation Thank you for your purchase of the TwinTube plug-in. The native version includes licenses for systems supporting RTAS (Digidesign ProTools), VST (i. e. Cubase, Nuendo, WaveLab, ...), and AU (Apple Logic). The ProTools TDM version includes licenses for systems supporting TDM, RTAS, VST and AU plug-ins.
The Analog Code plug-ins. TwinTube The TwinTube module is the first combination of two essential tube effects in a single processor, that is, saturation effects along with harmonics processing. Both stages work separately from each other and are based on individual processing stages.

In the analog original of the TwinTube Processor, a special circuit comes into play for overtone/harmonic processing that involves a combined coil/ condenser system working in conjunction with the tube. The con- trol reacts dynamically to the audio signal and thereby processes both overtones as well as a signal’s phase structure.
Power LED With a click on the POWER LED you can turn the TwinTube on or off. The switch settings of HAR. ON and SAT. ON are stored so that the previous state is recalled when the TwinTube is activated with the POWER LED switch function. The POWER LED is illuminated when the plug-in is activated.
Aside from har- monic tube distortion, the accompanying tube limiting effect should also be considered. For further details on the saturation effect refer to the “Introduction” on page 5 and 6. TwinTube Processor...

The SIG. LED indicates that an audio signal reaches the input. In the analog world this LED helps the operator especially in complex setups to determine immediately whether the TwinTube actually receives any signal. In the digital domain it simply tells you that the channel where you inserted the plug contains a signal that is loud enough to ensure correct processing.
Vocals Optimizing vocal tracks is a highlight among the processing appli- cations of the TwinTube. Often further EQing is not necessary any- more in order to lift a voice from a mix and get it up front. A recom- mendation for female voices: HARMONICS switch to 6, HARMONICS control to about 2 o’clock, SATURATION to about 12 o’clock.
