The Micro Rack Series[1][2] (or Micro Studio Series) of half-rack effects was made by Boss in the 1980s.

As you might expect from products branded with the name of their guitar pedal division, they're cheap and simple compared to the fully fledged Roland-branded effects. Personally, I like them, because of their straightforward interface with one knob per parameter, and their charming, slightly lo-fi sound. They're more than good enough to do the job, and add bags of character. They also look pretty cute.

Although MIDI was well established by the time this range of effects came out, they were budget devices, so didn't implement anything so fancy. Instead, they each have a footswitch input to turn the effect on and off, which makes them ideally suited to be toggled with a digital sequencer, with a little creative soldering.
