Remarks:  This edition of the JAX Convolutor uses over 120 included IR Files for reverberation. All functionality is enabled (except loading own files). The upcoming JAX Convolutor PRO will allow to import / load unlimited individual IR files. Please understand that convolution uses conceptionally much CPU and requires larger rendering buffers to perform successfully. JAX Convolutors are consequently stereo processing convolutors, that are optimized for usage with very large IR files. This allows them to be used as mastering reverbs. Convolution effects are well known and commonly used in music production since many years. Convolution is a highly complex signal processing approach, that needs some certain computation power. The recorded impulse response of a real world environment is used to render a reverberation effect onto any audio material, so that it sounds like the source was played in that original room or location. Some further adjustments and manipulations can be applied to refine these results in realtime. IR files are mostly files recorded with special equipment, but basically are just usual audio files (srereo) with a reverberated sound of an ultra short impulse. It is even possible to capture synthetic reverbs and other effects with this technique, for instance from famous ancient vintage equipment, as rare plate and spring reverbs. If other kind of files are used, some wired special effects can be achieved thru convolution or just some kind of creative audio garbage. But also rhythmic effects are possible when the correct IR sizes are used (correctly adopted to the current tempo of the composition). A comprehensive manual is shipped with the app.

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.
