Read full description

Unleash sumptuously smooth saturations, disgracefully dirty distortions, and maximally mad mashups! BLEASS has designed Fusion to be one of the – if not the – most versatile and adaptable distortion and saturation plugins available today, able to completely change its entire tone and character in an instant. The magic comes from the way in which wavetables define the sonic results of processing, and so empower the plugin with the versatility to satisfy your every sonically-destructive whim. Whether you want to spice-up your audio with the lightest sprinkle of sizzle, smother it in a luxuriant fluffy blanket, or shatter it into fractured shards, BLEASS Fusion provides the perfect waveshaping weaponry for the job. And should you find that the 58 included wavetables don’t quite fulfill your distortion dreams, importing your own custom wavetables is simply a matter of dropping a file into a folder. A pair of multi-mode resonant filters allow BLEASS Fusion to focus its fury on particular frequencies, or can be used to tame its more extreme excesses. And with a full complement of modulators that add movement and dynamism to your sound, a huge palette of expressive, rhythmic and evolving distortions are just waiting to be explored. BLEASS Fusion is also available for desktop More information on www.bleass.com/fusion

Verdict

The call

The clearest difference is in-app purchases: BLEASS Fusion at none against Tera Pro's 6. BLEASS Fusion also leads on review sentiment (100% vs 69%) and rating (4.8 vs 4.6). Tera Pro's advantage is update cadence (every 5 days vs every 2 months) and ratings volume (154 vs 18). On ads, device support and iOS requirement there is nothing between them.
