A classic algorithmic reverb effect based on the Freeverb algorithm by Jezar at Dreampoint. A Freeverb-style Schroeder/Moorer reverb based on the classic 8-comb + 4-allpass topology, with simplified controls and no stereo spread. This reverb creates lush, spacious ambience through a network of comb and allpass filters. Freeverb is widely used in electronic music production, ambient music, and sound design to add depth, space, and atmosphere to audio sources. The algorithm provides a smooth, musical reverb tail that works well on everything from vocals to synthesizers. This reverb only functions in mono and provides no stereo imaging, and the user can expect the same behavior as a classic Freeverb implementation otherwise.

Freeze a performance edition of your setlist with each song’s concert key, capo position and matching written chord shapes, then export the complete PDF book. HOW IT WORKS 1. Create a setlist from saved charts, then open Gig Book from Setlists. 2. Create an edition, choose concert roots and capo positions, and add performance notes. Read each written-shape chart. 3. Save the edition, build its complete PDF, preview it and share the PDF with its edition record. Transpose, capo suggestions, Nashville numbers, setlist Stage Mode, samples and chart history remain available. Stage Mode now displays the written chord shapes that match its recommended capo. Long PDF charts flow across pages without silently clipping their final text. WHAT TO KNOW Up to 20 songs per book and 50 saved editions. Source charts are copied into the edition, so later library edits do not change it. Transposition is chromatic; minor labeling does not reharmonize a song. Use a standard full capo and verify the arrangement before performing. Share only charts you have permission to distribute. iPhone and iPad.
