WMD Bus Rider - Stereo Multiband EQ/Dynamics Processor WMD Bus Rider is basically a mastering-style processor for your Eurorack mix bus, squeezed into only 4hp. It’s designed to sit at the end of your signal chain and polish an entire patch or submix live, instead of processing individual voices. What makes it interesting is that it combines three major mix-bus tools into one module: DJ-style 3-band isolator EQ Multiband compression Lookahead limiter That combination is pretty rare in Eurorack, especially at this size. Main workflow You run your stereo mix into Bus Rider before your output module or recorder. Then you can: tighten low-end tame harsh highs glue sounds together increase loudness prevent clipping make live sets translate better on PA systems It’s very much aimed at live performers and performance mixers. EQ section The isolator EQ works similarly to DJ mixers: each frequency band can be boosted or completely killed crossover points are adjustable low band can optionally sum to mono The low-mono feature is genuinely useful for live venues because huge stereo bass can disappear or become muddy on club systems. Compression section The multiband compressor splits lows, mids, and highs separately, so: kick/bass can stay controlled mids can remain punchy highs can stay smooth without pumping the whole mix That gives much cleaner compression than a normal single-band compressor. Limiter section The limiter is there to: maximize loudness catch peaks prevent clipping add optional saturation Lookahead limiting is especially valuable in modular because transient spikes can get wild very fast. Performance-oriented features A few things make this more than just a “studio processor in Eurorack”: preset saving (9 presets) CV control over parameters assignable modulation input compact 4hp footprint integration with the WMD Performance Mixer MKII ecosystem So you could automate EQ sweeps, dynamically alter compression behavior, or morph between mix states during a set. Who it’s for This makes the most sense if you: perform live with Eurorack use a performance mixer record stereo modular jams want cleaner/louder final mixes without external gear don’t have room for separate EQ/compressor/limiter modules If your system is more experimental/noise-oriented and you want raw uncontrolled dynamics, it may be less essential. Closest hardware philosophy It feels conceptually similar to: end-of-chain mastering processors DJ isolators Elektron-style bus compression workflows compact live mastering chains But optimized specifically for modular performance. For 4hp, it’s actually extremely feature-dense.
