Part of this is about having access to a constant level of quality. You can record almost any Roland instrument and find the same sounds based on the same core technology. This also means that sound created on the high-end Fantom workstation may be able to be used on the portable and (comparatively) affordable MC-1
Zen-Core is based on a combination of sample-based waveforms and virtual analog technology. It also supports modeled filters, LFOs, envelope modulators as well as the "high-resolution control" of the sound design and performance parameters. (Are you ready to accept input from a MIDI 2.0 controller?)
However, none of this does not mean that your $ 3,000 workstation is no better than a $ 500 groove box. Zen-Core supports instrument-specific extensions such as analog behavior modeling on the Jupiter-X. Using these features shouldn't prevent you from using a sound on a lower-end device, but it does open up more ways to optimize the sound … and maybe it sounds a bit better.
Zen Core Will Do It First show yourself a software update for the Fantom 6, 7 and 8 workstations, the Jupiter-X synthesizers and the RD-88 stage pianos. And it will arrive on the MC-101 and MC-707 a little later this year.
