Mela Lab Module: Feedback

- In Mela, signals flow left-to-right within a lane and top-to-bottom between lanes. Sometimes, however, you may want to send an Audio signal in the opposite direction to create feedback. - The Feedback module allows you to do just that by taking the output of an Audio bus, delaying it by 1 sample, and merging it with the Audio signal passing through the lane. - To keep feedback under control, the module has a built-in hard clipper that limits the maximum output level to +6dBFS. - At the moment feedback doesn't work with the Poly signal type, i.e. it auto-collapses it to Audio, but I plan to support it once Audio buses can transmit Poly. - Feedback is a Mela Lab module and part of Collection 4.

**Build 449** Feedback Module - The built-in hard clipper threshold can now be set to +6, +12, or +24 dBFS. - In most cases, +6 dBFS is recommended, but higher thresholds can be useful. For example, when creating a phaser effect with feedback. - The new clip indicator shows when the clipper is triggered. If you're not using clipping creatively, adjust parameters to avoid activation. - The Level parameter range has been changed to [–100, +100] %. - Like the Digital Delay module, it now flushes noise below -⁠160 dBFS to prevent buildup from the digital noise floor. - The module has graduated from Mela Lab and is now under the Signal Router category.

**Build 444** - Feedback Module: The module graduated from Mela Lab and can be found under the Signal Router category. Poly Buses - Audio buses in Mela now support Poly signals. - This means the Audio In, Audio Out, and Feedback modules can send and receive Poly Audio signals. - If a bus sender or receiver module isn't receiving a Poly signal as input, the bus signal collapses to Stereo Audio at the receiver before merging with lane Audio signal.

**Build 431** - Similar to Digital Delay, the Feedback module now has a built-in hard clipper that limits the maximum output level to +6dBFS, to keep feedback under control. - Modules like Clipper and Meter can be used to manage and monitor levels in the feedback path.
