The inspiration for the Phaser should also be no stranger to many. Mu-Tron Bi-Phase is responsible, among other things, for many of the classic floating and spacey electronic sounds of Jean-Michel Jarre & more. Its special feature is the dual construction with two sweep generators that control Phaser A and B and can also be controlled via expression pedal, just like the original. Compared to the original, a ramp waveform for the two LFOs and separate controls for the modulation depth have been added. Under the hood, each sweep generator can be inverted, allowing for interesting stereo effects. In addition, the filters can work up to 12-pole for more powerful effects; the original only offers 6-pole filters. Envelope followers, as well as serial or parallel use, extend the effects spectrum. Bi-Tron impresses with a full and powerful basic sound; classic phaser effects are quickly created. But the additional functions also invite you to experiment, which can end in truly spectacular stereo effects or even wacky modulations.
Third in the bunch is the Flanger BL-20. Here, a somewhat lesser-known piece of hardware served as inspiration - the B.E.L BF-20. This plug-in is also dual for stereo effects, with two delay lines creating the familiar flanger sound. Three control modes are available: Manual, Env and Auto, each with associated controls. The modes can also be combined, if required. Feedback and Reverse options on one channel are used to adjust the effect. There are also some exciting new features compared to the original effect. Zero Crossing allows for deeper flanging effects, the stereo width is infinitely adjustable, and the Auto mode has been expanded to include more waveforms, as well as a tempo sync. But the highlight is the fold-out Function Generator. Here, you can freely draw in a modulation curve, which then influences the manual mode synchronously to the song tempo or free-running.
