需要 Flanger、Chorus 等 modulation plugin 的網友可以考慮 Audio Damage 的四合ㄧ plugin QuatroMod。他們家的軟體我有幾個,聲音和介面都不錯,而且價格不貴,客戶支援則算普通。 https://www.audiodamage.com/collections/software/products/ad040-quatromod Audio Damage has deprecated their classic Liquid through-zero flanger, Fluid multi-mod chorus, and Vapor diffusion chorus plugins, combining them into one convenient new modulation effect called QuatroMod. They also included a reverse port of their hardware FreqShift Eurorack frequency shifter. QuatroMod is four effects in one handy, vector-based resizable UI. Audio Damage QuatroMod is available now for $49. Owners of Liquid, Fluid, or Vapor can upgrade for $10 via Products > Upgrades. QuatroMod requires an AU, VST, or AAX plugin host. As with their other recent macOS plugin updates, iOS versions are forthcoming.
