Pure Strings Instrument & AUv31.3 - App Store

Pure Strings is an inspiring professional iOS app that allows musicians to transform their iPhone or iPad into a richly expressive string instrument. With nine expertly sampled articulations and textures, it offers a wide range of string ensemble options. At its core is the Morphpad, a touch-sensitive interface that allows seamless blending and shaping of sounds. Simply slide your finger to explore and morph through a variety of string sounds and effects.
Pure Strings combines the high-quality sound typically associated with desktop virtual instruments with the intuitive, tactile experience of mobile devices, delivering an expressive, versatile and responsive instrument. Pure Strings responds fluidly to your creative impulses. Swipe across the Morphpad to blend, mix and layer string tones with simple finger movements. Whether you're exploring classic sounds or venturing into modern sonic landscapes, the app provides a large variety of strings sounds, including sustain, pizzicato, staccato, harmonics, trills and tremolo articulations, as well as string machine, synth and vintage tape string sounds.
Pure Strings lets you access the full dynamic range - from soft piano to bold fortissimo - not only through keyboard velocity, but also through the Dynamics Strip next to the Morphpad, Mod Wheel or automation. In addition, the built-in arpeggiator transforms chords played with short articulations into synchronised arpeggios that follow your host tempo, adding an extra dimension of musical expression.
Customise your sound with control over attack and release time, or shape your tone with the Con Sordino button, which softens the sound to create a uniquely mellow and emotional atmosphere, replicating the effect of a mute used by string players. To further enhance your sound design options, Pure Strings includes a versatile EQ, high-quality reverb and a delay effect that syncs to the host tempo. These effects morph seamlessly as you explore the Morphpad, but they can also be set as master effects by disabling the Morphpad control, giving you even more flexibility in sound design.
Pure Strings works as a standalone app or as an AUv3 plug-in within your favourite iOS DAW. Whether you want to open the app in standalone mode using USB, standard MIDI, network or Bluetooth MIDI connections, or integrate it as an AUv3 plug-in into music apps such as Logic Pro, GarageBand or Cubasis, Pure Strings offers connectivity and integration across a wide range of workflows.
