The main new functionality of Strobosoft 2 is that it can work as a VST or Audio Units plug-in, so it can be inserted on a channel strip in any compatible DAW on both Mac or PC. The strobe display can now be resized to fill the whole screen, allowing it to be viewed from across a stage, for example. Also, there's a new pitch graph that displays the input signal in terms of duration and pitch.
Strobosoft 2 features a Tap Tune function that Peterson say is ideal for people who need to tune woods during the construction of instruments, but also for those that want to tune-up percussive instruments. A final touch is the inclusion of two new 'skins', each providing a visually different look for the plug-in.
