What is Helm?
Helm by Matt Tytel is a great free synth for making all types of EDM.
Helm VSTis available on Windows, MacOS, and Linux as 32 and 64-bit. This synth comes with 274 presets.
Why Helm is good?
The Formant filter is great at creating vowel sounds by picking different spots in the X/Y pad.
The biggest feature in this synth is probably the LFO modulation. This lets you link the Low-Frequency Oscillator to different parameters around the plugin to change their values.
How can you use Helm?
Helm is great for dubstep. And really any kind of sound design.
