The essence of the sound is determined by its dynamic performance: the way it reacts around transients creating its signature. In many situations, best results can be from medium-slow attack; and medium-fast release settings: passing transients present in a signal, while the compression law and timings then played out as the side-chain reacts and recovers both controls the overall levels and adds ʻpunchʼ as the transients are shaped. The ʻSOFTʼ mode in the C1LA also adds a new compression curve, acting not just at the threshold knee point, but across a broad input range of about 15dB.
