So, I bought Kev's Squeezer, and it's great!
Not quite as difficult to use as I had heard, I was expecting far far worse.
So far I've factory reset it and just been tweaking existing standard patches, learning the menus etc. There's a few presets like Double Chin that can be tweaked to be something quite useable, but unfortunately there's only like 5 sounds that are worth using. I plan to download some of the sounds from the cgraham site which has a bunch of simple useable sample sounds etc, but I need an SD card reader.
My main takeaway from using this for a few days is how much I love the Future Impact. Way better tracking, way easier to dial simple usable sounds on the fly, and has a global master volume!!! Pretty annoying having to turn down the volume on single patches, or having to enable 'all params' via the Squeezers menu just to turn down the clean blend volume on any patches - why are the Paul Turner patches so loud for example lmao? The clean blend is boosted so much. Volume jumps across default patches is a problem in general, tbh.
I have spent years making lots of very useable/recognisable synth sounds on the Future Impact, so I'm sure in time I'll get the Squeezer to a more useable state but for now, it's a lot of squelchy fun!
