Echoa Manual
Firmware 1.4.0 (c052620) · SDK 0.11.0·Stereo dual delay · four engines · delay-to-reverb continuum
This manual simulates having the module plugged in and accessed via the web programmer. You can view manual information in line with the controls, seeing everything in context. If you are developing for the SDK, use the manual hooks to embed this information in your firmware.
Plug in the module via the front USB port and these controls become live and bi-directional.
Module Introduction
Two independent stereo delay lines. Each carries its own time, feedback, mix, engine character, diffuser, multitap, and damping.
There is a continuum from delay to reverb: short times with high feedback give comb resonance, the middle range is stereo delay with selectable engine character, and high Diffusion and Bloom turn each line into a plate- or hall-like tail.
Three symmetrical performance pages provide delay line controls, and Settings mode is reached by holding B2 + B3.

The core delay controls, one column per line: Line 1 on the left, Line 2 on the right. Set the delay length and how much comes back here, then use Space and Engine to shape it.
Delay length for line one. Set curve and max delay time in settings.
With Clock Format on 24 PPQN and a clock present, this pot stops being continuous and selects a musical division instead.
Delay length for line two. See line one.
How much of this line's output returns to its input. Below unity the repeats decay, at unity they sustain (green pip), and above it (red pip) the line builds into heavily clipped self-oscillation.
Feedback for line two. See line one.
Blend between the dry input and this line's delayed output.
Mix for delay line two. See line one.

A preset captures every pot on every performance page, all parameter-lock buffers, the per-line engine selections, and the settings bound to the preset. The first slot is the boot slot: it loads automatically at power-up.
From the panel, enter Settings. The slot pot on left middle, picks the target, then the action pot commits when held hard counter-clockwise to save or hard clockwise to load. The gesture has to be held for three seconds. A flash on the rings confirms it. Slots can also be saved, named, and backed up from this programmer.
