And if that still sounds too much like hard work, there's a surprisingly effective random option. In a nutshell, it's an automatic pattern generator that enables one to set a few key parameters that determine the melody and groove of a riff, with the results being sent to the piano roll. The new Riff Machine feature tied into the piano roll makes it easy to come up with riffs, arpeggios and chord progressions.
Not many DAWs boast such a straightforward yet comprehensive M/S tool and Image-Line are to be applauded for making a potentially confusing technique so accessible. There are lots of useful presets, too, divided into an Effects bank (with presets for 'stereoising' mono signals and other interesting stereo effects), and a Mixing bank. M/S processing might not seem like an obvious choice for an FL Studio effect, but it's such a powerful concept that its inclusion can only be a good thing.
