“I just wanted to follow up and tell you how much I appreciated your great service, all of your help in choosing what I needed, and the prompt delivery.” - Katie, VA

Radikal Technologies RT-1701 EFFEXX offers two main effects processors with eight selectable effect algorithms each and three additional pre and post effects that are all simultaneously available. The eight selectable effects algorithms are delay, vintage delay, chorus, phaser, flanger, rotor cabinet emulation, pitch shifter and string filter.

The additional effects are a gain stage with overdrive, a flexible EQ / multimode filter section and a fully editable reverb effect. The delay times and modulation rates can be controlled with a tap-tempo function: just hit the tap button four times with quarter notes of the current beat and RT-1701 EFFEXX will adapt the correct tempo automatically.

For each effects program, RT-1701 EFFEXX stores up to eight effects setting snapshots. Snapshots can be used to recall a desired effects parameter set quickly and easily. A built in LFO allows you to create smooth transitions between snapshots. Furthermore, you can synchronize this LFO to an external clock signal or control the snapshot selection with a control voltage. Snapshots not only store the settings of effects parameters, they also hold a value for an external/auxiliary control voltage output. 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 low pass, band pass and high pass settings. Control the post filter with a an external envelope and change the color of the RT-1701 EFFEXX input signal with the different effects it offers. A wealth of new synthesizer sounds can be created with this setup!

The string filter creates astonishing Karplus-Strong sounds. The control voltage input can be used to control the frequency of this algorithm, turning RT-1701 EFFEXX into a Karplus-Strong oscillator.

***IMPORTANT NOTE: Please test your item before getting it fully assembled. For example, with digital pianos, unpack the keyboard portion, power it on and test all the keys. It is very rare that these items arrive with defects, but it is still a good idea to test it before spending time getting it fully assembled. Use caution when unpacking your purchase from its box, as some needed parts and pieces may be packed in and amongst the packing material. Be sure to save the carton and all packing materials, in case of a needed return. Do not write on the box and do not discard!
