Simple tempo-synced volume envelope for that classic EDM pumping effect. All parameters exposed for automation. The default setting will probably do what you need, but you can also save/load presets. Set floor value, delay, curve, release point - control the envelope like a standard ADSR __ If you're having an issue, please email me at support@scalenumbers.com rather than leaving a review, as apple doesn't send developers any alerts when reviews are left, so I won't know you've tried to contact me.
