There are two oscillators, each of which can draw on triangle, sawtooth, square and noise waveforms and features its own LFO. The oscillators can be added, subtracted or multiplied together, while each LFO has its own ADSR and modulates its oscillator's pitch or volume.
Other features include a high/low-pass filter, an arpeggiator, a ping-pong delay and 3-band EQ. There are 93 factory presets.
Unique to the iPad version is the Extended Keyboard, which enables you to play in a particular scale and key.
