M4L envelope follower with advanced features


Product Description


Made with gen~

gen~ powered: sample by sample accuracy guaranteed!

Powerful editing tools

Lot of options to meticulously shape your sound source

Modulate any parameter

Link REF's modulation to any parameter inside Ableton Live


REF allows you to modulate anything you want in Ableton Live: other devices, the user interface, and third party plug-ins, using sound as source.

You can shape the incoming audio source with the low/high pass filter, listening the source in peak or rms modes, then design the envelope exactly how you need it, using tools as relative/absolute modes, linear/logarithmic modulation, and positive/negative directions. You can even work on your envelopes with standard EG parameters as attack, hold, release, and a global delay time.

REF uses a big display to give you an accurate visual feedback: it will help you to check the incoming audio signal, set the threshold level, and view the real envelope generated, which will control the chosen target parameter.

REF is a great tool for any kind of modulation: kick/bass side-chain combinations, driving filters, and experimental uses asking for controlling parameters from an audio source.

Developed on the Max 6 engine, taking advantage of gen~, REF supports both 32 and 64 bit mode.

REF is developed using exclusively standard Max objects, to guarantee compatibility with latest Live and Max For Live versions.

“The most flexible envelope follower around, and for this range of price is definitely a good option to expand the sonic possibilities.”
