Description
Squall uses the reverb DSP from Mutable Instruments Clouds (by Emilie Gillet). Knob A sets tone and knob B sets depth, which also drives the wet amount in the one-knob style of the module. Freeze holds the reverb tail, and scan colours the frozen buffer or, below 50 percent, lets a little new audio in. It is sold on Gumroad as a pay-what-you-want download with a suggested price of 5 USD, and the source and releases are also on GitHub. A drumlogue version is in DanielMajid/squall_reverb_drumlogue (MIT, no releases yet).
Install notes
Open KORG KONTROL Editor, drag the .nts1mkiiunit file into the effects category and sync. The unit can also be built from source with the logue SDK.
