Ebbe und Flut s/n 155
The Ebbe und Flut is the brainchild of German engineer Carsten Schippmann. Initially conceived as a simple filter box, it took on a life of its own as its designer added facilities including compression, distortion, dual envelopes, an LFO, sample & hold, and a VCA. The result is an impressive package in a relatively compact 2U rackmount box.
The Ebbe und Flut is a high quality analog signal processor with two very fat and precise VCFs, each with 12 different functions at their core. A very effective automatic soft-knee compressor, controllable with only one knob, and with very good adjustment properties is part of the device as well as a really musical distortion unit. The signal chain finishes with a VCA controlled by either envelope generators or a noisegate.
Each filter has its own envelope generator (with Attack, Hold and Release) and is additionally controlled either by an LFO (with waveforms triangle, sawtooth or rectangle), Sample & Hold or by the envelope follower control voltage. In addition, an external footswitch can modulate each VCF independently. The resonance can also be modulated. Moreover, from the input signal a very reliable and flutter-free trigger will be generated even under difficult signal conditions. Modulations are adjustable in either Normal or Inverse.
An array of external signal and modulation inputs / outputs provide very flexible and extensive linking possibilities to your studio.
