## What is Assemble Light?

Assemble Light utilises the same synthesizer engine as Assemble for iPad. It features four bandlimited oscillators with six voices of polyphony each, a lowpass filter, an oversampled, tempo-synchronized stereo delay effect, and a vibrato effect. The synthesizer's parameters can be modified in real-time from the options menu.

The synthesizer can be played by sequencing patterns of notes with Assemble Light's sequencer using the on-screen keyboard. The sequencer has two modes of playback that allow as many as four sixteen-step patterns to be played either discretely or sequentially at a wide range of tempos.

To unlock even more features, including the ability to save and load sequences, real-time audio visualization, audio recording, video clip generation, and greater parameter control, download Assemble for iPad on the App Store.
