LayR is a massively polyphonic, multi-timbral synthesizer for iOS devices, optimized for modern 64 bit CPUs and capable of delivering up to 256 voices of rich, multi-layered and textured sounds. LayR's primary sound components are called Performances where a Performance is a set of Instruments and each Instrument is a set of Layers and each Layer is a complete synthesizer. A performance can consist of any number of instruments each with its own MIDI channel and crossfading keyboard span. Each Instrument can consist of any number of Layers to a maximum of 128. Each Layer has a dual oscillator that can morph with modulation between two shapes and phase states, two rich and warm state variable filters, a wave folder and a mixing section to blend oscillators and filters in any serial/parallel combination. For modulation (frequency, amplitude and phase) there are two Low Frequency Oscillators ranging from DC to audio frequency switchable to optionally follow keyboard pitch and restart phase when a note is started. Two loopable ADSR envelopes ranging from fractions of a second to over 100 seconds, an amplitude ADSR and a random number generator with a smoothing filter. With stereo delay, reverb and EQ on the output section LayR excels at not only emulating normal analog synth sounds but also at creating massive pads and huge spacy ambient textures with extremely long evolution cycles. Focused at keyboard players looking for a mobile synth that can be reliably used live on stage LayR is equally at home in the studio. An extensive selection of usable instrument and performance presets are included which can be loaded using MIDI bank select and program change messages in the same manner as hardware synths. LayR sports almost unparalled and extremely flexible MIDI control. Every parameter in the synth engine can be assigned to any MIDI Control Change number and parameters spread across multiple Layers can be grouped and controlled by a single MIDI cc with assignable range and direction. There is also an 8 track, 16 step Arpeggio Sequencer which can be used to create all sorts of exciting polyrhythmic looped patterns or even ambient generative music. Each track can have it's own speed, playback mode and length. On top of all that LayR has a MIDI Controller Mixer that can be used during performance to control the synth engine in real time and can also transmit MIDI cc's from LayR's output port to other destinations. Full IAA, Audiobus, Audio Unit and Link compatibility means LayR can be used with all hosts and other music apps on iOS and desktop DAWs.

Cality is a creative midi processor allowing subtle rhythmic enhancement, controlled chaos and everything in between. Add swing or accents, quantise the pitch of notes, use a probability gate or use the cloud module to add addition notes all under midi control The cloud section takes techniques common in granular synthesis and brings them to the realm of midi notes. It adds additional notes to the ones you are playing. This can be a simple rhythmic accompaniment or it can bring new textures from your synths by generating a cloud of tiny notes almost entering the realms of black midi. The note sections gives a fully automatable/midi controllable note quantiser with a range of scales, a transposer and the ability to constrain to simple chords as well The tempo section allows the addition of swing and accents to incoming midi notes as well as providing a probability gate Cality is great for bringing life to simple midi loops or patterns or for taking you deep into creative realms.
