Thanks for reaching out to us Vamshi. We've taken your feedback onboard and a new update is on the way! 3.7.5 resolves the reverb issue completely -- making it sound just like the old one but with the added environments. We hope you enjoy -- if you have any issues, please let us know! Thanks for your understanding.

Thanks for the review Sapana! We're happy you are enjoying Resonance. We've also released a new version that improves reverb significantly without quality loss. We hope you like it. :)

when I export after applying the settings, everytime the audio is the raw sound and has no reverb added. sounds fine when you play it in the app with reverb. disappointed. Update: This still doesn't work with version 1.4.0 sounds like it's now in the next room and no effects. sounds perfect still when played in app. export is broken.

Thank you for your patience John. You're absolutely right and it appears the upgrade to the export library caused this issue. A new version is now available that resolves this issue but but reverb isn't supported on export. We recommend trying 1.6.0 as it's quite a big improvement over 1.4.0. :)

What’s new

REVERB: We've built a fully-custom in-house reverb engine inspired by Freeverb -- this behaves like the old v2 version you all enjoy. Another added benefit is having over 5 reverb environments and no distortion:

- Room
- Hall
- Stadium
- Plate
- Spring

Each environment offers its own vibe -- play around and see what you like!

SPEED: We also upgraded the max playback speed from 1.5x to 2.0x, allowing you to create night-core style music.

We hope you enjoy this new update.
