They are leaned more toward tehcno field, but thier are enough to sastify all musical disciplines. Velocity is fully programmable. I have not had any problems with midi messages. Rhodes are decent, but Rolands are better. Wurltizer is very good.
Atmospheric sounds are the best in the industry, always have been The effects are extensive.
For a combination, you get 5 insert effects and 2 master effects. You route sounds through them quite easily. Thier 89 possible effects, high quality. When sampling, you can also apply these effects to the sample, which gives a lot of flexibility. For what I understand, the Triton Sampler is limited, but the effects make it a farily decent sampler in camparison with others.
