Currents by After Later Audio is a complex digital modulator that can work as an LFO, VCO or envelope. Currents works differently than most LFOs or envelopes. First you select whether you need an attack/decay or attack/release envelope or an LFO. With the parameters Shape and Slope you set the waveform. Smoothness leaves the waveform largely untouched in the center position, turning this knob clockwise adds a Waveshaper , turning it counter-clockwise acts as a lowpass filter that rounds out the waveform.

So it is easily possible to set classic waveforms and AD/AR envelopes with the known progressions. In between there are values and curves that one would rather expect from a well-equipped function generator or that go far furthermore. The three speed ranges refer equally to the A/D/R times of the envelope modes and to the LFO. In Red mode, the frequency extends into the audio range which qualifies Currents as an excellent oscillator.

For the four outputs, there are four extremely interesting modes. Mode 1 outputs four different waveforms in parallel, mode 2 addresses the CV to the four outputs one after the other via Morphing , mode 3 shifts the phase of output 1 a bit with each output, mode 4 is comparable to a frequency divider/adder. With five control voltage inputs with bipolar attenuators for the main parameters, and inputs for gate, 1V/oct and Clock the module is comprehensively controllable and modulable. Apart from the color scheme and the knobs, Currents is exactly the same as the original MI Tides.
