Last week, I was lucky enough to get a review copy of Tempo Rubato's NLogPoly Synth. This is one of the few synth apps available from the Mac App store, and is currently priced at USD$24.99. If you're like me, you are a bit shocked at the prices of everything in the app store due to how cheap mobile apps are on the iPhone, but 25 bucks isn't bad for a softsynth, especially considering it can be used as a standalone as well. But is it really worth it? We'll delve in below.
