SynthMaster 2.5 might be the most comprehensive and complete synth we've ever come across. The interface may not be the prettiest, but it's definitely intuitive and user-friendly, which counts for a lot more in our book.
This semi-modular monster has a feature list that's exceptionally extensive and broad, while the sound is truly outstanding. You can take quick control with the eight ‘easy mode’ control knobs or dive in deeper on the Layers page.
Many developers say that they've produced the one and only synth you'll ever need, but we've always felt that was a dubious claim. In SynthMaster 2.5’s case, though, it’s one that rings true.5 Stars
