On "False Idols, " the dreamy orchestral strings that enrich "Nothing's Changed, " sung by Francesca Belmonte, began as an experiment with a synth sound, as did the song's skippy drumloop.
The remaining 8 x 4 pads above now function as a step-sequencer -- with a sound selected, tapping these adds drum hits in the respective position in the drumloop.
Push lets you add drum hits by tapping the pads on and off as the loop plays, but you can also record a pattern in live if you're a bit of a finger-drummer.
