I tried the SoundStage at Tokyo Festival of Modular on Saturday and talked a bit with Mr Worng, whose name I now realized I forgot to ask (very nice person anyway).
He told me he used to do live sound for bands and was used to filtering/EQing instruments in a number of ways and that module kinda comes from that experience, plus the way the SP1200 has specific filters on its outputs (apparently someone wrote a detailed article about that).
The goal is to have an easy way to mix a number of sound sources and place them both in the stereo field and make them mix together nicely using filtering. There are about 20 filters in the module and I forgot the exact number but quite a bit of VCAs too.
It works well, and the depth control makes it go from unfiltered to filtered, with CV control. There will only be some minor changes before going in production (made by WMD in the US), for example the low-mid section will have one less jack so that there can be one fully centered, and some small adjustments.
It’s not mean to be a Mackie-like modular mixer but rather an useful tool to easily have different sounds sit together well when mixed. Really interesting module, and it pairs well with his LRMSLR module too…
