Cube Synth is a groundbreaking new software instrument giving you the power and flexibility of additive synthesis together with easy editing and morphing capabilities. Macro parameters allow you to control this beast with unequalled ease. Intelligent sound morphing capabilities enables you to easily create complex evolving sound scapes, vocal phrases or stunning rhythms simply by choosing up to four sound sources from a predefined set. Then add one of the predefined envelopes and a unique, complex sound preset containing thousands of parameters is created! If you want to dive deeper into the inner secrets of this synthesis monster you can manipulate each parameter individually to get precise control over the sound.

About

Ulzii Drone

Read full description

Ulzii is an instrument for fingertip meditation, inspired by Mongolian throat-singing (khoomei) and the tradition of drone music. At its core is continuous tuning, free from the twelve equal-tempered Western scale. Two ribbons let you freely set the pitch of two voices; touching the central pad shapes the color of that voice's resonance (like a vowel) depending on where you touch. The name "Ulzii" comes from the endless knot found in traditional Mongolian ornamentation — echoing this app's core idea of an unbroken, continuous drone. - Continuous tuning ribbons: note names are just reference points — slide your finger to tune freely to anything in between - Central pad: touch position shapes vocal resonance (overtone color); an optional VOWELS overlay shows common vowel positions - Three playing modes: UNISON (locked to voice I), FOLLOW (a delayed echo of voice I), and ORBIT (an autonomous, ever-moving layer) - Sleep / meditation timer: 3–30 minutes, gently fading out at a slower tempo — ideal for bedtime or meditation Headphones are recommended. This app does not collect or transmit any personal data or performance data.
