Outgrowth is a sample-based instrument built collaboratively by Aqeel Aadam Sound and BlankFor.ms. Designed with creativity, flexibility, and performance in mind, Outgrowth provides unique, multifaceted ways to reimagine audio with your mouse or keyboard. MPE compatible. Includes 100+ presets and 200+ samples built by BlankFor.ms. Outgrowth features five unique engines for processing samples: - Stem: A basic one-shot style player that repitches the sample - Retain: A granular stretching engine that sustains the sample indefinitely - Reflect: A looping algorithm that loops the sample at a consistent rate across all pitches - Radiate: An additive resynthesizer that maps each harmonic of the sample to a sine wave oscillator - Delve: A wavetable synthesizer in which the sample becomes the basis for a completely unique wavetable Outgrowth also features five standout audio effects for shaping your sounds further: - Subvert: A unique shaper that flattens or inverts the sample’s volume - Submerge: A singular effect for adding dimensional realism to sample repitching - Strike: A dynamic control for adding an acoustic-like response to sample playback and performance - Ripple: A one-knob tape emulation handcrafted by BlankFor.ms that can be subtle, deconstructive, and anywhere in between - Smear: A pre-ADSR reverb for congealing notes and blurring boundaries between pitch and texture And further still, Outgrowth offers a robust modulation matrix for generative or performative control over all parameters. Control every single parameter within Outgrowth via LFOs, unique random sources, velocity, note pitch, aftertouch, MPE control, and more. Finally, Outgrowth offers a robust preset system, including more than 50 bespoke presets and over 100 samples by BlankFor.ms. Explore ethereal ambient pads, haunted lofi keys, shimmering tape-infused plucks, gnarled percussive textures, and more.

Low Poly Synth is a generator of melodic atmospheric sounds with billions of unique timbres. The app is built on modified synthesis algorithms from Fractal Bits, Relic Waves, and Relic Flow, with the addition of pure tone generation code. The sound space is divided into 4294967296 presets, each corresponding to a set of 8 sample textures. The volume of an individual sample can be adjusted in the top panel or via MIDI (Settings -> MIDI Mapping). The bottom panel is a classic musical keyboard that sets the note for the sounds in the set. Each note triggers all 8 samples at once - together they form a complex harmonic pattern that almost never repeats over time due to the different lengths of the looped fragments. Features: * search for new sounds with three buttons: next random set, edit code, previous set; each set of 8 sounds corresponds to a code of 8 characters (you can save/copy/paste it as plain text); * three types of keyboards for live performing: on-screen, PC keyboard, MIDI input; for the on-screen keyboard, you can set the number of displayed octaves and scale; * 20+ parameters can be controlled via MIDI or directly through the app interface: Settings -> MIDI Mapping; * real-time audio recording to WAV (32-bit); * export to: WAV (one file or a set), SunVox (samples + effects in one file), text clipboard; * the LCK button freezes individual samples - they will not change during the search for new sets; * Audio Unit Extension (AUv3), Wi-Fi export/import. Double clicking on a parameter opens a window for setting the exact value. If you enable the Hold option, the notes will play endlessly, without reacting to key release (noteOff) events; turning the note on again works like turning it off; there are two ways to enable this option: 1) using the Hold parameter in the "MIDI Mapping" window; 2) by pressing the HOLD button, which appears in place of LCK while playing the musical keyboard: press HOLD, release the desired notes - then the released notes will continue to play.
