What synth tools do you offer?

You will find Serum 2 presets, Vital presets and wavetable libraries for cinematic, darksynth, synthwave, bass, metalstep and heavier hybrid productions.

Do you still make drum and guitar tools?

Yes. The store still covers Superior Drummer 3, EZdrummer, GGD, Perfect Drums, Fractal, Neural DSP Quad Cortex, Kemper, Line 6, TONEX and related heavy-production workflows.

Where should I start?
