Bitwig Preset Linux Studio Plugins Master Bus
Input should be around 0 in k-meter mode so use the "Preamp" macro to pad or gain into the chain until your master out starts hitting +19 (which is the ceiling for the chain). This uses free plugins from the free LSP Plugins bundle that is exclusively for linux. This is designed to be a relatively low-latency starter master bus processing ceiling for new projects that's easy on CPU as well.
