## What is JR?

The JR-808 is a simple yet fully-featured beat sequencer designed for iPhone, based on the classic TR-808. Features include 16 instruments (kick, snare, hats closed, hats open, crash, sidestick, tom low, tom high, ride, clap, conga low, conga high, tambourine, cabasa, cowbell and clave), up-to 64 steps per pattern (16, 32, 48 & 64), pattern queue/hold (i.e. hold off playing the next pattern until the current pattern finishes), volume and pan mixers for each instrument, tempo tap, unlimited pattern saves, instrument clear, pattern clear and six presets to get you started. 

Toggle multiple steps with a single tap and drag. Tap +16 to extend the pattern up-to 64 steps. Navigate through each bank of 16 by using the left and right arrow buttons. 

Designed to be there in an instant, whenever and wherever inspiration strikes — whether you just want to note down an idea, or work something up from scratch, the JR-808 is super easy to use, with nothing to get in the way of your on-the-go creative flow.
