Updated 5-20The occasional audio drop outs and going mute was annoying, but infrequent. This update fixes that, and just makes it better. If you're thinking of this or Mini Synth Pro, (which is plagued with clicks and pops and developer doesnt get it) stop and forget about mini synth pro, get THIS. NLog Synth Pro is THE best. Yes iMS20 is excellent too, but still this beats even that.Original review:I have almost all the synths in the app store. iMs20, Mini Synth Pro, Xenon, Jasuto, Sylo, Crystal XT, Synthtronica, SynthX... list goes on and on and on. This is easily one of, if not the best analog, as well as just generally one of the best all around synths.I've not noticed any clicking. Crucial for pro recording and as a recording artist that's one thing that must be perfect. The amount of tweaking possibilities are astronomical.The arpeggiator is fantastic, deeper than most others. Patching is easy peazy. Multi voices, copy /paste, File Share, Rverb, Delay, filters, oscilators, envelopes, FX, Stereo soind....Oh my donkey! This has everything. Any musician or just synth lover must get this. If you like very high quality, get this. Seriously...you'd have to pay big big bucks for a real world synth that does less or even the same thing this does with the same quality!
