The Arplus module from Zlosynth Instruments is a robust Karplus-Strong 6-voice resonator that gives you a bevy of musical scales at your fingertips. The Arplus works by selecting a particular chord based on the scale you select, stepping through the notes of that chord via the Trigger input and button. Use the Tone control to set the root note, and use the Chord control to select the particular chord. Both controls have corresponding CV inputs that let you create intricate sequences or melodic randomness. Choose from 31 different types of scales that include Western, Arabic, Indian, Japanese, and even quarter tones.

Internally, a burst of noise gets generated to create the sound, however, if you want more control over your noise bursts, an external input is available for you to patch in whatever you'd like. Use the String control to adjust how many virtual strings remain resonant after the trigger—up to 6 strings can resonate at a time allowing for soaring expanses of ambience and gorgeous clusters of notes. Sculpt the sound right on the module with a built-in filter, including resonance and cutoff, along with a Contour control that moves from short percussive bursts to long swells of washed texture.

Of course, no resonator would be complete without a stereo output, and the Arplus doesn't disappoint. Choose from three different stereo spreads: Ping Pong, which alternates voices between left and right, Root, which sends the Root to the Left and everything else to the Right, and Haas, which creates a stereo spread using the psychoacoustic Haas effect. The Arplus from Zlosynth is more than just your typical resonator, with an easy-to-read scale selector and a lovely sound that's sure to win over your heart and ears.
