Latest Release

v1.4.0 · 9/4/26

Steadier pots. Every pot is filtered and gated: an idle knob no longer drifts with converter noise, so delay times hold still and repeats stop warbling in pitch.
Parameter locks arm on the first touch. Recording starts after half a percent of travel instead of three, and the loop is anchored where the knob sat before you moved it. Clearing a lock still takes a firmer nudge.
Heads up: presets saved on 1.3.0 read as empty on 1.4.0. Your slots are not erased. Update through the web programmer and it backs up and migrates your presets for you.
Built on Alchemy SDK 0.11.0.

v1.3.0 · 8/21/26

Interactive manual. Echoa now carries its own documentation. Every knob, jack, button, and setting explains itself in the web programmer.
Output gains have been bumped at default.
Clocked inputs and modes are now clearer and more robust.
Clipping light. Rebuilt on the SDK's indicator. Brief peaks no longer trip it; it lights when the input is actually clipping.

v1.2.0 · 8/14/26

New: jump home with B2 + B3. Tap Buttons 2 and 3 together (release before the Settings hold kicks in) to jump straight to the first performance page from anywhere. An accessibility and utility feature.
Parameter locks run four times longer. Recorded knob motion now loops up to 16 seconds per lock, up from about four. Recording and playback gestures are unchanged.
CV in Settings bug fix. Patched CV modulation and external clock no longer pause while the Settings menu is open.

v1.1.0 · 7/17/26

New: colorblind-friendly LED palette. Settings → Global → P6 switches every LED on the panel between the standard scheme and a colorblind-safe scheme designed for red-green color vision deficiency (deuteranopia / protanopia). Red-vs-green meaning pairs (page colors, feedback over-unity, the VU meter, damping) move to a blue / orange / yellow axis with brightness separation. Switches instantly, no reboot needed.
The palette choice is saved with your presets and appears in the web editor as LED Palette (Standard / Colorblind).
Heads up: presets saved on v1.0.0 cannot be loaded by v1.1.0 changes the on-device settings layout. Your slots aren't erased, but they will read as empty; re-save your presets after updating.
