Dave Smith Instruments launches the Mopho x4 synthesizer keyboard, see the introductory video below. It has 4-voice polyphony and more controls than the Mopho keyboard. The price is $ 1299.
The included software editor is provided by SoundTower. We are not so enthusiastic about SoundTower’s software editors. Given the experience with the software editor of the Mopho, the Mopho x4′s editor will be lacking standard VST support, which is a shame.
