*EURORACK - 3.5mm*

The ES15 is a complex multi-functional module that provides various slew and sample functions.

The Smooth function will place a positive and negative slew (glide) on a changing input voltage for lag effects, voltage controlled portamento, and non-linear, low frequency filtering. With the [CYCLE] jack patched to the [IN], the unit will oscillate yielding a voltage controlled triangle wave LFO. A high level into the [HOLD] input will hold the current output level, whether the unit is oscillating or processing an external control voltage. This is identical to a track-and-hold function.

The Stepped function can be used as a sample-and-hold with voltage controlled slew rate limiting. Slew rate limiting limits the size of the step at the output. With the step size limited to a small value, if the [IN] input is a random voltage, the [STEPPED OUT] output is a random voltage also, but it will only vary slightly from step to step, gradually covering the entire range of the input random voltage. No large changes in the output will be allowed. With the [CYCLE] jack patched to [IN] and a trigger applied to the [SAMPLE] input, complex staircase waveforms are generated.

The COUPLER is an internal comparator comparing the Smooth and the Stepped Outputs . This is useful for generating complex control voltages and for patching to a random voltage generator.

NB: The Coupler outputs are most usually used to link the Smooth & Stepped Generator sides together. The outputs are especially stiff pulses generating near-to-rail outputs so users should be aware that these are "out of the ordinary" outputs and due attention must be paid when patching to other modules.

The 3.5mm Module includes 2x Passive Jack Splitters to optimize patch-programmability of the module and reduce the need for external multiples.
