This simple difference produces some interesting and unusual effects, e.g.
- Delay echoes play alternately forwards and backwards.
- The time between a note and its echo varies, depending on the location of the note in the delay buffer (unlike a normal delay, where the time between a note and its echo is constant).

As you'll see from the above, it can be useful to know where the current delay buffer write position and direction are, and for this reason Meringue features a large graphical overview of the sound in the delay buffer, and of the motion of the write position.
Meringue has a filter/saturation section for creatively treating the sound.

The delay time and the filter LFO can be synced to the host application's tempo. The phase of the delay and the LFO can also be reset manually.
