Klevgrand Fosfat — Plugin Boutique Coupon Sale (Through May 17, 2026)
Fosfat reframes transient shaping as a kind of “transient fertilizer.” Instead of squeezing or boosting what is already in the signal, it injects two new sound generators that lock to the incoming transients. A clean noise-based generator adds attack snap and clarity, while a tonal generator can add weight, body, or pitched character. The result is a punch tool that lets you sculpt drums and percussion with surgical control over the attack window without smearing the rest of the mix.
Where classic transient designers raise or lower what already exists, Fosfat lets you treat each hit as a layer-able event: pinpoint kicks, snares, claps, congas, or even sampled loops, and tune the added energy in dB, length, and tonal character per element. Klevgrand also ships a deep preset library so engineers can audition aggressive, subtle, or experimental shaping styles before tweaking parameters by hand.
