Wave is a track starting instrument from Novation's app's development arm, Blocs.
The app is divided into browsing, editing and recording. Included are six sound packs, with more available.
At its heart Wave is a sampler with a powerful time-stretching engine and features waveform editing.
During our test with an iPad Mini 4, there seemed slight anti-aliasing when making big tempo/key changes, but it is brief and incremental changes are not affected.
