User reviews

Incredible useful rechnology

This is one of. The. Most useful and inventive music creation apps on the appstore...more physical modeling apps like this please

No sustain/note hold

Thus I don’t use it.

Bundle price not discounted properly

But this review is about strng. High quality, minimal ui.

I own this app, and the other 3 apps in the bundle is the same price as buying them separately.

spannende Klänge

sehr interessante Klänge, die mit wenigen einfachen Einstellungen über ein großes Spektrum verteilt sind - von sehr realistischen Annäherungen an echte Saiteninstrumente sowohl gestrichen als auch gezupft oder geklopft zu sehr weirden Tönen.

ein bisschen verwirrend beim Spielen ist, dass weisse Linien zwischen zwei schwarzen nicht gespielt werden können. Da entspricht die visuelle Darstellung nicht ganz dem, was man tun kann. das könnte noch optimiert werden.

Superb and unique synth

Amazing string synth! Very large sound pallet with a minimalistic GUI. A powerfull sound design instrument. ( Would be nice to have an update in the line of the fantastic one we had for Tardigrain recently. )
