KV331 Audio offers the SynthMaster Player ($29 value) virtual instrument as a free download until January 4th, 2020.
Don’t confuse this time-limited offer with KV331 Audio’s freeware plugin called SynthMaster Player Free. That one is, as its name implies, always free. Also, that other version of Synthmaster Player only comes with 500 presets.
See also: Free Synthesizer VST PluginsThe “full” version of Synthmaster Player, the one featured in this article, typically costs $29 and comes with 1,800 presets in total. In that regard, it is a significant upgrade over SynthMaster Player Free.
All that said, Synthmaster Player is still rather limited compared to the “real” SynthMaster plugin which offers unlimited control over the synthesis engine. Synthmaster Player only offers twelve editable parameters, and these are assigned differently for each preset.
OK, with the SynthMaster ecosystem basics out of the way, let’s take a closer look at SynthMaster Player and why you’d want to add it to your music production software arsenal (especially while it’s free).
SynthMaster Player is based on the same synthesis engine as the full edition of SynthMaster. It has the same synthesis capabilities under the hood, except the user can’t access most of the parameters.
This means that you won’t be able to build sounds from scratch with SynthMaster Player. On the other hand, you can edit up to twelve parameters in a preset. These parameters differ from preset to preset. In most cases, you’ll get access to the filter cutoff and resonance, some modulation settings, and FX properties. The user can also bypass the active FX modules.
So, if you’re serious about sound design (as in, you need a synthesizer to create custom sounds), SynthMaster Player is not for you.
On the other hand, if you’re looking for a synth that comes with 1,800 professionally designed presets that you can fine-tune, SynthMaster Player is one of the best deals around. If you like using synthesizers in your music, there’s no reason not to upgrade your virtual instrument collection with SynthMaster Player.
