Operation
Eos can be used in a mono-in/stereo-out or stereo-in/stereo-out context. Of the three reverb types in Eos,
one, Plate One, always sums its inputs to mono and is tailored for mono-in usage. The other two types have
stereo inputs. The reverberators create a stereo output signal even if the input signal is mono. The dry signal
is always passed through without summing.
Eos provides a number of presets to help you find settings appropriate for different instruments and contexts.
We suggest that you give Eos a try right away by dropping it into one of your current projects and flipping
through the presets. Once you’ve heard what Eos can do, come back to this manual when you’d like to read
about how to tailor Eos to your musical needs.
We’ll describe each of Eos’s controls in turn, starting with the controls at the top of the window.
Pre-Delay
The pre-delay simply delays the incoming signal before it reaches the reverberators, and hence how long the
reverberant sound will be delayed relative to the dry signal. Typically pre-delay is added to a reverb effect to
increase the perceived size of the simulated reverberant space: the bigger the space, the longer it takes the
reflected sound to reach the ears of the listener. Pre-delay also has creative applications. If the processed
signal is delayed enough, relative to the original signal, it becomes a separate sonic element. This works
particularly well with percussive sounds if the DECAY time is set fairly short.
You can adjust the pre-delay time in either of two ways. First, you can click and drag on the small circle in the
left of the graphic display. As you drag towards the right, the pre-delay time increases and the circle starts to
pull apart, representing the decoupling of the reverberated sound from the original. Second, you can click and
drag vertically on the displayed numeric value itself. Drag upwards to increase the pre-delay time, drag
downwards to decrease it. If you click to the right of the decimal point the value changes more slowly,
