In 1987 Roland showed the D50, quickly pushing away the DX7 as best sold synthesizer... for about a year.. till Korg showed the M1 which was to become the best sold keyboard of all times.. in the D50 Roland combined samples with synthesizer technollogy and effects... which set the road for the synthesizers and workstation as we still know them today..
Roland U20 a fully PCM sample based keyboard, Rolands first Rompler, you could eddit the envelope of the samples and add effects, but that was about it. Nevertheless it was very succesfull.
And then there was 1991 and the Sound Canvas SC 55 that became the standard for playing GM/GS files... almost a must for any band using backings in the early 90's
Also in 1991 Roland showed the JD 800, with a combination of samples and subtractive synthesis. Roland answered to the call from people that wanted a real synth and not a rompler. It became very popular with sound designers, there was also a rack version JD 990
In 1996 there was the 76 key XP80, part of a huge fammily of of Roland synths like the XP60, JV1080 and jv2080 that all used the same technollogy.. the synths consisted out of 3 major parts. A sound-source (pcm/subtractive synthesis) a sequencer and a controll part
Also in 1996 the Roland JP8000/8080 was presented, they where VA synths, to compete with Access virus and Nord Lead.. They quickly grew to become the most popular of the bunch and are the base of what Roland still uses for their VA synthesis
In 2000, Roland build the ultimate rack, of which people had been dreaming the whole 1990's Th XV 5080, which was to be found in almost any studio in the world for more then a decade..
The first decade 21st century was the Era of the workstation. Roland answered to this with their Fantom range The Fantom in 2001, The Fantom X in 2004 and the Fantom G in 2008 where very popular..
In 2003 there was the Roland V-synth combining variphrase modeling with VA moddeling COSM filters and the incredible time-trip pad. There was a rack version the XT in 2006 And in 2007 there was the V-synth XT which boosted 2 engines and is still my favourite synth ever.
