Hi!
I'm using Spark 2 in Ableton Live 9 Suite 64 bit. I just noticed that the Soft Clip feature works a bit strange, at least for me. When turned off ( icon is grey ) the audio level of Spark 2 won't go over 0 dBFS even if the Main Volume is at its highest. It means that a limiter is doing its job. When Soft Clip is turned on ( icon is blue ) the audio level easily jumps over the 0 dBFS when I trigger a sound. Interestingly when I trigger sounds repeatedly and fast, the audio level goes back to the 0 dBFS. Additionally all the transients are smeared badly. So we do have a limiter or clipper, it just has such a slow attack time that it makes the clipper unfit for its duty, namely keeping the audio level under control. As I understand soft clipping isn't about smearing the transients and letting the rest through. It is similar to limiting only softer. But it still shouldn't let the audio level over 0 dBFS or a set level.
I hope you fix it. A well made clipper could add something to the sound of the plugin too.
Best regards,
