The EFFEXX RT1701 offers two main FX processors with eight selectable FX algorithms each and three additional Pre and Post FXs, that are all simultaneously available. The eight selectable FX-algorithms are: Delay, Vintage Delay, Chorus, Phaser, Flanger, Rotor cabinet emulation, Pitch Shifter and String Filter. The additional FXs are a Gain Stage with Overdrive, a post EQ/multimode filter section and a fully editable Reverbration effect. The delay times and modulation rates can be controlled with a Tap-function. Just hit the Tap-button 4 times with quarter notes of the current beat and the EFFEXX will adapt the correct tempo automaticly.
For each FX program the EFFEXX stores up to eight FX setting snapshots. Snapshots can be used to recall a desired FX parameterset easily and quick. But there is much more. A built in LFO allows for creating smooth transitions between the snaphots. Furthermore, you can synchronize this LFO to an external clock signal or control the snapshot selection with a control voltage. Snapshots do not only store the settings of FX parameters. They hold a value for an external control voltage as well. With this control voltage you can control a parameter of any other module.
There is another control voltage input for the post filter frequency control. Beside EQ functions the post filter can be used as a multimode filter with lowpass, bandpass and highpass settings. Control the post filter with a an external envelope and change the color of the EFFEXX input signal with the different effects the RT1701 offers. A lot of new synthesizer sounds can be created with that setup.
The string filter creates astonishing Karplus Strong sounds. The control voltage input can be used to control the frequency of this algorithm with 1 Volt/Octave. With that feature the EFFEXX can be used as a Karplus Strong oscillator.
