Yes, my Metalbox matrix mixer is in one of the old deep Bugs boats fortunately.
Slope Detectors output three separate gates. One when the input voltage is rising, one when it is falling and one when it is in a steady state. You can plug pretty much anything (LFOs, noise etc…) into them and get gates out. Useful for lots of stuff - like syncing to modules that don’t have their own gate/trigger outputs. One thing that is good fun is plugging in a joystick module so you then have gates depending on what direction you are moving it that can trigger different events/sounds.
It’s a module I like in any system. Not really there to make up for any Bugs shortcomings necessarily.
