*** Note: DerVoco is an Audio Unit effect extension and requires an AUv3 compatible host app, like AUM, BM3, Cubasis or GarageBand. It does not run as a standalone app *** Make your synths or drums speak and sing! DerVoco is a vintage vocoder emulation. DerVoco uses analog modelled components including filters, envelope followers and companders to create a warm vintage sound instead of digital techniques like FFT. Features: • AUv3 Audio Effect and Audio Music Effect, works in all AUv3 compatible hosts. • Internal polyphonic VCO may be used as a carrier and can be controlled via MIDI, when plugin is loaded as AU MFx. • A special "input mode” where the carrier and modulator signals are encoded as the left and right channels of a stereo input signal. In this mode any synth plugin (e.g. BeepStreet Zeeon) may be used as a carrier signal. • 11 or 15 bands with on-screen equalizer. • Controllable filter resonance continuously blends from smooth to sharp and ringing sound signature. • Built in compressor and noise gate • Optimised to the limits: 60 filters take 4% CPU on latest iPads.

BLEASS Alpha Synthesizer is a versatile virtual analogue polyphonic synthesizer built for immediate, hands-on sound design. Its three oscillators combine variable waveshapes and pulse widths with unison, hard sync, cross modulation and ring modulation, while dual variable-state filters with drive add further colour and character. The streamlined interface follows the natural signal path, keeping powerful synthesis controls accessible at a glance. Bring sounds to life with three ADSR envelopes, two multi-waveform LFOs and extensive modulation possibilities, while the Motion Sequencer adds rhythmic and expressive movement that can work hand in hand with the built-in arpeggiator. MPE support extends the performance possibilities, and BLEASS' efficient audio engine keeps the experience smooth and responsive on mobile devices. A complete built-in effects section includes Overdrive, Bitcrusher, Tremolo, filtered ping-pong Delay and Reverb, adding everything from subtle movement to more radical processing directly within the synth. More than 200 factory presets provide ready-to-play sounds and starting points for your own creations. BLEASS Alpha Synthesizer can be used as a standalone app or AUv3 instrument on iPhone and iPad. Also available for Windows and macOS. More information and technical specifications available on: https://www.bleass.com/alpha/
