Works perfectly in my cases! - only problem was clumsy instructions for setup and it took whole day to fix it to work with my mac - needed to setup firewall again..

Toimii kuin unelma!


Easy to setup with Mbp + ableton live

Kotistudioilu tän kanssa sujuu moitteettomasti. Pianon äärestä voi kontrolloida iPhonen välityksellä Logiccia ja näin keskittyä langattomasti olennaiseen. Editorilla voi luoda uusia kontrolleja erittäin monipuolisesti. Itse loin EZDrummeriin kontrollit ja nyt voin syöttää komppeja pianokoskettimistoa vaivattomammin. Siis minulle korvaamaton apuri.
