ES27 - Transient Generator

Let's Go Shopping

!! Available January 2019 !!

The ES27 is a Transient Generator with voltage controllable rise/fall times. It is a scaled down version of the ES114 Universal Slope Generator and provides some of the basic functions that can be patched on the ES114 but occupying less panel space in your system and freeing up the ES114 for other functions.

Common uses for the ES27 are:-

  1. As a simple 'AR' type envelope generation: apply a trigger to the [IN] jack to initiate an 'AR' envelope with a variable shape from 'slope' through 'triangle' to 'ramp'
  2. As a voltage-controlled low-frequency oscillator: With the [IN] jack unpatched the ES27 will cycle continuously, The [DC] jack gives you a DC output (0V to +5V),
  3. As a voltage-controlled clock (especially suitable for clocking the ES23 Sequencer Programmer and the ES28 Touch Sequencer). With the [IN] jack unpatched the ES27 will cycle continuously. The [END] jack provides a LOGIC clock pulse (0V to +5V) with a variable duty-cycle based on the [FALL] and [RISE] settings.

When in 'oscillator' mode the frequency range extends from a high around 2.5kHz to a cycle-period in excess of 4 minutes.
