WaveCloud is an innovative granular synthesizer that offers powerful tools for manipulating and playing sounds. Granular synthesis divides an audio sample into tiny fragments, called grains, each typically a few milliseconds in length. These grains are then manipulated independently in terms of pitch, duration, position in time, and amplitude. Unlike traditional synthesis, the capability to manipulate tiny grains of audio offers enormous precision of sound control, transformation, and compositional possibilities. WaveCloud offers a wide range of tools for experimentation – oscillator, LFOs, filters, envelopes, routing matrix, innovative WaveGlide and Orbit modules for grain movement, effects, MPE support, extensive waveform editing, customizable themes, MIDI CC control, aftertouch, audio pool manager, and 200+ presets to get you started. Granular synthesis is extremely versatile and can produce a vast range of sounds and textures, from subtle, atmospheric sounds to complex, dynamic ones. WaveCloud offers dozens of parameters, enabling you to sculpt the sound grains in any way you wish – textural pads and atmospheres, time-stretched effects, glitchy and stutter effects, vocal and instrumental manipulations, granular synthesis percussive sounds, experimental effects, as well as microtonal and harmonic soundscapes. WaveCloud features a drag and drop system for importing and exporting of audio files and presets. It has its own built-in Preset and Audio Managers to help keep everything in order. WaveCloud even features a fully-fledged zoomable audio editor along with a suite of tools to crop, fade, cut, copy, paste, and normalise your samples. We include a morphing 3-state Oscillator to support the granular engine. The granular engine allows up to 50 grains per second per note, with grain lengths up to a second in length. Grains can be sculpted with our morphing envelope generator, manipulated with our LFOs, FEGs and VCFs, and passed through lots of randomisation to keep things continually evolving. WaveCloud also features two unique features for adding movement to audio grains. Orbit mode allows you to play sweeping patterns tied to the physical host tempo of your DAW, and WaveGlide is a sequencer with glides and fades from one location to another. To top it all off, we include 7 built-in effects, delay, reverb, chorus, overdrive, phaser, resonator, and 8-band EQ. The resonator controls per-note feedback and dispersion for amazing MPE effects. WaveCloud is not only a deep and powerful granular synth but also a fun way to create many incredible sounds. Features • Over 200 presets • 3-state morphing oscillator (sine, square, saw) • Morphing grain shapes • 2 low-frequency morphing oscillators • 4 multistep envelope generators • 2 visual filters (series and parallel modes) • Per-channel feedback resonators with dispersion • MPE Support (per-channel pitch bend, aftertouch, and CC74) • Orbit mode • WaveGlide sequencing • Fully Featured Mod-Matrix • Direct record and playback of samples • Built-in sample editor with editing tools • 7 built-in effects • Built-in Audio Manager with drag and drop support • Preset Manager with easy import/export, drag and drop • Colour scheme editor

Auto Fills is a random MIDI generator app for creating drum fills for your drum synth apps or hardware synthesizers. It works as an Audio Unit AUv3 plugin with the supported host apps such as AUM, Loopy Pro, Logic Pro, Cubasis, Nanostudio, apeMatrix etc. In Auto Fills, you are working with a drum kit. You can either create the kit by adding drum parts and assigning them MIDI notes/channels yourself, or you can select a kit templete from the settings menu for an app or hardware for quick setup. - In Kit mode, you can assign a probability value to each drum part. - In Velocity mode, you can assign a velocity to each drum part, and you can also introduce velocity variety for them. - In Duration mode, you can set the drum fill length as well as the waiting time before and/or after the drum fill, in beats or bars. - If you've set "wait before the fill" and/or "wait after the fill" durations in the Duration mode, the drum fill won't be played during the waiting periods. If you have a favorite drum sequencer, you can route it through the Auto Fills, before the drum app, like - Drum sequencer -> Auto Fills -> Drum App And you can block the incoming MIDI from the drum sequencer during the drum fill. You enable the option in the Duration mode by toggling "block incoming MIDI during the fill" option. You also have an option for randomizing the drum fill on every cycle. Assigning probability values is crucial in the Kit mode. If you want to hear a specific drum part mode, just increase it's probability. If you would like to hear a drum part less ofter, just decrease its probability. If you set a probability to zero, it won't play in the drum fill. - Density knob leaves out notes from the drum if you decrease its value. It introduces rests in the drum fill without regenerating the fill. - Voices knob sets the maximum number of drum parts can be played at the same time (polyphony). The algorithm chooses a value between 1 and the maximum voice count randomly on every step of the drum fill. - Rate note sets the speed of the drum fill. - Generate button lets you regenerate the drum fill. Changing the kit by adding/removing parts, probabilities and voice count also regenerates the fill automatically. Auto Fills is a MIDI app and it does not produce it's own sound. You need to route Auto Fills MIDI out to an audio app's MIDI input in order to hear the voice.
