If you've got a new iOS app, make sure you let us know about it by emailing email@example.com with all the details.
Mike Gao Polyplayground, £4.99
There is a synth built into this app, but it’s designed primarily as a MIDI controller. Its chord buttons are based on an isomorphic layout, which means that they’re all in the same key, while the Horizontal/Vertical buttons enable you to change the pitch space.
Boulanger Labs csGrain, £6.99
A live audio multi-effects processor that you can use to “create new sounds and new musical textures by transforming your voice, your instrument, or your favourite songs from your iTunes library”. It features a stereo granular sound processor and ten additional audio effects.
Julien Bayle Digital Collisions, £2.99
The latest in a long line of generative music apps: this one is based on physics collision algorithms. Touch the screen to create particles, then watch as they take on lives of their own, bumping into walls and each other. Sound shaping options can be accessed via the Menu button.
VirSyn Addictive Synth, £3.99
An update for this highly regarded iPad synth. There’s now a spectral noise generator with dynamic filter structure, a new reverb unit, support for the new iPad’s Retina display, 32 new presets and additional MIDI controllers. The price listed above is the current discounted one.
SS Series Smart Studio A, £10.49
A self-contained music production app that offers a 4-track recording studio, drum machine with step sequencer and digital sampler. The latter two devices come with their own soundbanks.
Iglesia Intermedia SpaceLab
A monophonic synth that can be played in four ways: keyboard, graph, guitar and wind controller. SpaceLab is a fully programmable instrument that also comes with three effects and an arpeggiator.
Kelfar Technologies WorldScales
If equal-tempered scales are proving too restrictive, WorldScales is here to help. It’s an app that enables you to tune each note in an octave individually (+/- 100 cents) and comes with 35 sample-based instruments. Many of the presets employ lesser-known scales, and MIDI In functionality means you can plug in a keyboard.
Synthetic Bits Little MIDI Machine 3.0, Free
Everyone’s favourite free analogue-style MIDI step sequencer now has Virtual MIDI and background audio support, meaning that you can use it to trigger other iOS apps. Various other things have been added too, including MIDI Input support and the excitingly named supersequence feature.
