this is a great kick plugin. i'm a fan of analog modelling synths in general. they often don't fully capture the feeling of a certain instrument, but for the compromise of really unique parameter sets that just enable a whole different workflow producing sounds that are new while referencing something older. that's the case with this plugin as well. it was so confusing first, especially the fact that there is no single parameter for the decay of the kick, but rather all parameters together defining how that behaves. it feels more like changing the genetics of the kick species rather than just making a kick superficially, if that makes sense. (it does not? well, it would if you tried!) this synthesizer doesn't have a lot of downsides, but what i don't like about it is that you can't define the body's frequency in 12edo notes rather than frequency in hz. also sometimes it's hard to find a good transient sound without messing too much with the way the pitch of the kick falls. i used it several times now and i often find myself rendering it to a new audio track at some point and then go on with other effects until it's really cool. but the basic concept and a lot of the controls of this thing are already great.
