What it does

CRMBL is a free, open-source delay from UnplugRed with a wide feature set. The developer says that "in the right hands" it can move from normal echoes to "highly textural results".

Pitch-shifted feedback: the pitch shifter sits in the feedback path, so each repeat can climb or fall further in pitch.
Asymmetric ping-pong: left and right repeats can use uneven timing, for off-balance stereo bounces.
Reverse delay: plays the repeats backwards for swelling, reversed echoes.
Dub-style time changes: parameters are highly automatable, and automating delay time gives classic dub pitch swoops.
Graphics: a GPU-drawn interface.

Version 1.0 is free and open source under GPL 3; the free version shows a small banner, and the developer's page also offers a paid version.

When to use it

CRMBL is a good free pick when you want delays that turn into texture, thanks to pitch shifting inside the feedback loop and reverse repeats. Compared with EchoBoy or Timeless 3, it has no tape or analog style models, no rhythm or tap patterns and far fewer modulation options, but it costs nothing. It is narrower than Valhalla Delay, which covers many delay styles in one plugin. Unlike any of those paid delays, its source code is open.

Best for: textural echoes, dub delay throws and rising or falling pitch-shifted repeats.
Genres: electronic, ambient, dub and lo-fi.
Look elsewhere if: you want vintage tape or analog delay character or deep rhythmic control; EchoBoy or Timeless 3 are better.
