Tera Pro brings together all major sound synthesis methods on one table. No matter if you want to recreate sounds from analogue legends or explore modern digital sounds with FM, Waveshaping or Wavetable synthesis. More can be added by In-App Purchases of new modules. Add some flavour of physical modelling and modules for additive synthesis. Combine them altogether for new sound experiences far beyond your wildest dreams. Tame this overwhelming amount of possibilities with Tera Pros intelligent user interface showing you only exactly what you need, paired with realtime oscilloscopes and level indicators helping you seeing what’s going on. Connect the modules with a flexible routing method without the visual cluttering of real wire cables needed in conventional modular synthesisers FAQ What does Tera Pro have that Tera Synth doesn't have ? 1) Additional Sound Modules - Spectrum oscillator ( borrowed from the heart of Addictive Synth ) - Wave shaper / folder opens the west coast synthesis - Vocal Morphing filter - KARPLUS (aka WaveGuide ) with new "Swarm" mode ( 3 detuned delays ) 2) Revised engine - Analog Polysynth Voice Modelling with characteristic subtle voice variations of timbre, pitch and temporal behaviour to get you "The" Analog Sound. - 128 vs 32 voices polyphony - Seamless Sound Switching: change presets during play without cutting off the sound. - 8 times unison for really heavy ambients - Envelope generators with Buchla style "end of cycle" trigger for generative music - Stack/Split Sounds - New effect section 3) Redesigned User Interface - Collapsible modules for clear view of modular structure - No more nasty popups for LFOs/Envelope generators - Realtime oscilloscopes added to selected modules 4) New Presets - About 1000 additional presets in there.

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
