LayR is a massively polyphonic, multi-timbral synthesizer for iPad and iPhone, optimized for modern 64 bit devices delivering up to 256 voices of rich, multi-layered and textured sounds.

LayR's primary sounds are called Performances: A Performance is a set of Instruments where each instrument is a set of Layers and each Layer is a complete synthesizer. A performance can consist of over 100 instruments each with it’s own MIDI channel and crossfading keyboard span. Voices are assigned to each layer in each instrument until the audio engine runs out of available voices. This means that with normal playing technique it is possible to create extremely complex texture on each note or even to have a single insane monophonic instrument equivalent to 100 synths all playing at once!

Every Layer has a dual oscillator which can  morph with modulation between two shapes and phase states, two rich and warm state variable filters and a mixer to blend the oscillator with filters in any serial/parallel combination. For modulation (Frequency, Amplitude and Phase) there are two aux oscillators ranging from DC to  audio frequency switchable to optionally follow keyboard pitch and restart phase when a note is started. 2 loopable ADSR envelopes ranging from fractions of a millisecond to 100 seconds, a volume level ADSR and a random level 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 ambient textures with extremely long evolution cycles.

Focused at keyboard players looking for a mobile synth that can be reliably used live on stage it is equally at home in the studio. LayR is provided with an extensive selection of usable instrument and performance presets which can be loaded using MIDI bank select and program change messages in the same manner as hardware synths. There is also an 8 channel arpeggiator with a 16 step event sequencer for creating exciting polyrhythmic patterns. Full IAA and Audiobus compatibility means LayR can be used with hosts and other music apps on iOS.

How to enter the LayR Factory Preset Competition

For a limited time we are offering early adopters the chance to send us any great Performance or Instrument presets you make. The best presets will make it into the next releases of LayR with your name on the preset tags. If you make 20 or more you can have an entire bank with your name on the bank title. From LayR save the presets to iCloud Drive or grab them from iTunes, zip them up and put them in an email with the title LAYR PRESETS including the name you’d like us to use in the message body.
