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 also 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.
Pricing and Availability:
Available as Audio Unit and VST plug-ins (both Universal Binary) for Mac OS X, and as a VST plug-in for Windows.
Initially the plug-in runs in demo mode, in which it is fully functional, except that it will time-out after 15 minutes of use. Simply reloading the plug-in resets the time-out.
To remove the time-out, you can purchase a registration. The price is $19 (US dollars, plus VAT if applicable).
