DopplerPad is a full featured music generation tool for the iPhone & iPod Touch with 6 classes of instruments: Bass, Drums, FX, Lead, Pad and Sampler, each with a designated color. The DopplerPad instrument app lets you Make samples on the fly and mix. Compose and perform musical hooks, phrases and loops with a variety of custom synth and sample-based instruments. Use rhythmic and melodic automation to create phrases by freely moving fingers around the musical touchpad. Drags and taps come to life with responsive visual feedback, making the groove visible.

When a Drum Kit is selected, the touchpad displays a grid, and each cell triggers a different sound from the kit. To change the BPM, tap and hold the arrow to the left or right of the current tempo.
