Dawesome Abyss 2 – launching 20/08 – Page 2 – Instruments Forum

The reasoning behind multiple versions:

Abyss 1 is not unsupported, neither is Love 1. They continue to receive bugfixes and are kept up to date with new OS versions etc.

The reason for separate Version 2 is: NEVER change the sound of an existing project!
Abyss 2 was a complete rewrite, it has multiple ten-thousand lines of new code, it introduces tons of new audio parameters, the dsp kernel code has been further optimised and adopted to support the new features like “playing back user generated tone colours” and “playback of tone-colours that had been imported from wavetables”. Also some mild changes had been done, for example the output limiter has been replaced with a better one, but “better” also means “different”. Some of the automatable parameters have extended range now, which has the potential to confuse DAWs when they open an old project with automation data.

There is absolutely no reason to redo anything. Simply continue to use Abyss 1 on your old projects, and as soon as you start a new project or add a new track use Abyss 2 instead.
