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/

The MF-101S Lowpass Filter is a re-invention of Moog Music’s classic Moogerfooger MF-101 analog effects pedal. The hardware MF-101 Lowpass Filter, introduced in 1998, contained two complete modular functions: a classic, all-analog 4-pole Lowpass Filter paired with an envelope follower to impart dynamic motion to the filtered sound. Designed by Bob Moog and his engineering team, the MF-101 was a direct descendant of the original Moog modular synthesizers, adapted to process, modulate, and play with inputs ranging from guitar, voice, and synthesizer to any imaginable audio source. The MF-101 Lowpass Filter has been meticulously recreated as the MF-101S, capturing not only the warm and vibrant sound of the original, but also the organic way in which the parameters interact to create a musical playing experience. The MF-101S is an AUv3 effects plug-in that requires a compatible host or DAW to function.
