PROFILER OS 5.7 is available for your PROFILER™. This new version introduces five new, studio quality, „big machine“-type reverb algorithms: Spring Reverb, Natural Reverb, Easy Reverb, Echo Reverb, and Cirrus Reverb. It also brings some new routing possibilities and a lot of system enhancements.
Just visit www.kemper-amps.com/downloads for accessing the new OS and Rig Manager™.

Here is some brief info regarding the new reverbs. More details you find in the 5.7 Addendum manual that comes with the new OS:

The Spring Reverb is inspired by the most sought-after spring reverb for guitarists: the Reverb Tank from 1963. Two prominent characteristics define this legendary reverb sound: one is the lack of low frequencies, due to a steep low cut filter used in the original design. The other is the haunting sound that resembles water dripping in a cave. To faithfully recreate this effect, Kemper have provided a dedicated intensity parameter called “Dripstone”.

The Natural Reverb is based on the latest digital reverb science and technology. Natural Reverb is capable of creating all kinds of natural sounding rooms — from ambiences too short to be noticed, to lush and epic spaces. This also includes plate reverb simulations, and even artificial and synthesizer-like reverb pads — all achievable with just the turn of two or three knobs.

The Echo Reverb is a delay combined with a reverb. In other words: a Natural Reverb with a feedback control added to its predelay to create rhythmic repetitions of the reverb tail. So, instead of using a straight delay type for a rhythmic enhancement, use the Echo Reverb for diffuse and soft echo reflections, when you find a regular delay is sounding too concrete or direct for your needs.

The Cirrus Reverb starts where the Natural Reverb ends. Its specialty are long, ethereal reverb tails with exceptionally slow reverb onsets. For that reason, the Cirrus Reverb does not feature a predelay. The modulation pattern is also different to the Natural Reverb: it does not build up by time but stays consistent instead.

Effects placement - Now since OS 5.7 all the FX of the PROFILER incl. delay and reverb can now be positioned freely into any FX module before or after the Amplifier section.
To put delays and reverbs into their designated modules makes still sense though as these modules have special routing features which can be defined in the Rig parameters:

• DLY+REV Routing 0%: pure serial signal flow
• DLY+REV Routing -100%: pure parallel signal flow
• DLY+REV Routing 100%: only the delay tails getting reverberated

And then some

The Space effect is identical to the global version of Space in the Output Section. It produces the natural reflections of a small, neutral-sounding room. The most obvious result of these reflections is that a mono signal is converted to stereo; to soften the transients, a little diffusion is also applied. You can still combine the Space effect with delay or longer reverbs, without creating too much reverberation.
The algorithm is designed to be the shortest possible room effect, and therefore has no deep parameters. Use the Intensity parameter to control the strength of the effect.

The Legacy Reverb is based on the first reverb algorithm created for the PROFILER. The main purpose of this reverb type is to maintain full backward compatibility with Rigs that have been created before the advent of PROFILER operating system 5.7.
