Vengeance Sound's Multiband Sidechain3 addresses a genuine workflow problem in dance music production: achieving transparent, musically effective sidechain compression without the tedious routing and automation that traditional methods demand. The plugin splits incoming audio into two independent frequency bands - low and high - allowing producers to apply different compression characteristics to each, a particularly useful approach for preserving bass clarity while adding controlled aggression to mids and tops.
The technical implementation centers on three filter topologies (digital, notch, and steep) to separate the bands, paired with a high-quality FFT-based 2-band EQ. This architecture produces noticeably smooth transitions between frequency regions, avoiding the artifacts that plague cruder multiband designs. Triggering flexibility distinguishes the tool further; users can modulate sidechain compression via audio input, MIDI notes, or host tempo sync, accommodating everything from beat-locked pumping to sidechain triggered by external drum machines.
The interface deserves mention for its honesty - a graphic display shows the actual audible sidechain effect in real time, helping producers develop reliable ears for what the compression is doing rather than guessing from parameter numbers. The included 32 presets by Manuel Schleis provide legitimate starting points rather than gimmicky snapshots, covering practical house and techno applications.
Best suited for electronic producers who want sidechain control without diving into complex DAW routing, Multiband Sidechain3 competes effectively against native DAW tools and more complicated third-party options. It occupies a sensible middle ground between feature depth and operational simplicity, making it genuinely useful for both rapid sketching and detailed mixing refinement.
