LayR - Multi Timbral Synth

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.

Overview

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 its own MIDI channel and crossfading keyboard span.

Key Features

• 256 Voice Polyphony - Massive polyphony for complex layered sounds
• Multi-Timbral Architecture - Multiple instruments on different MIDI channels
• Dual Oscillators per Layer - Morphable waveshapes with phase modulation
• State Variable Filters - Two rich and warm filters per layer
• Extensive Modulation - 2 aux oscillators, loopable ADSRs, and random generators
• Built-in Effects - Stereo delay, reverb, and EQ on the output section
• 8-Channel Arpeggiator - With 16-step event sequencer
• Full AU/IAA Support - Works seamlessly with other iOS music apps

Sound Engine Details

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
• Restart phase when a note is started
• 2 loopable ADSR envelopes (fractions of a millisecond to 100 seconds)
• Volume level ADSR
• Random level generator with smoothing filter

Performance Features

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.

The app 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.
