Last week I posted about the iPhone Guitar app. Today, or actually yesterday, the iAno emerged (iPhone + Piano). In order to install you’ll have to Jailbreak your iPhone, but it’ll enable a complete four octave keyboard that allows up to 5 keys to be simultaneously played. According to Technabob, it’s jam packed with real piano samples and it’s creator, Mister Aardvark, plans to add an 88-key keyboard, switch sample sets, recording and playback and more.
