With its blend of wavetable and classic subtractive oscillators, flexible filtering and post-processing, and an extensive set of advanced modulation sources, BLEASS Megalit provides sound designers with a vast palette of timbral tints, shades, and colours to explore. Thanks to BLEASS' super-intuitive interface design, that entire sonic palette is within easy reach of even the most non-technical musicians. Megalit includes many innovations that will empower your sound designs: * Advanced wavetable oscillators with independent wavetable position and Fold controls across more than 130 wavetables. * Per-oscillator Unison mode for creating rich, layered sounds without loading additional synth instances. * Dedicated noise generator with high-pass and low-pass filters for flexible non-tonal sounds and sound components. * Resonant high-pass and low-pass filters, plus built-in Waveshaper and Bit Crusher processors for powerful sound shaping. * Four LFOs with independent timing curves and output smoothing for highly detailed modulation. * Advanced Motion Sequencer for creating complex repeating modulation patterns. * Per-patch performance controller response curves for expressive and predictable playability. * Built-in preset randomizer that generates inspiring, usable sounds at the touch of a button. * Built-in multiband upward/downward compressor for precise control over dynamics, punch, and presence. All of Megalit's parameters, settings, and controls are presented with intuitive visual feedback, so you always know exactly what the synth is doing. Despite its immense sonic capabilities, Megalit remains exceptionally CPU-efficient, leaving plenty of headroom for additional instruments, effects, or simply more instances of Megalit. BLEASS Megalit is available as an AUv3 plug-in or standalone app. Also available for Windows and Mac. More information: https://www.bleass.com/megalit
