Sinevibes has introduced the third generation of its classic envelope sequencer plugin. Now available for Windows, Mac and Linux, version 3 of Inertia is a completely new development inside and out, with much more flexible and precise DSP, plus a super-functional graphic interface that’s more quick and fun to use than ever.
At its core is a multistep envelope generator with four separate envelope parameters per each step, with more than 50 possible shape variations. This generator is driven by an elastic step sequencer that has both polymetric and polyrhythmic abilities, and also offers a very wide range of timing settings. A single Inertia preset holds up to 8 sequencer patterns which can be switched on the fly. The final envelope signal is shaped using an ultra-smooth, analog-style low-pass filter, and is then used to modulate the level of the plugin’s input audio.
Thanks to its incredible ease of use, Inertia is a universal, highly flexible tool for quickly creating expressive level accents, sidechain-style pumping, elaborate tremolo effects, sophisticated gating and strobing patterns – and much beyond.
