If you make it sound too much like a synth, it will just sound like a guitar part played on a synth.
I consider my music to be Progressive Synth Pop, which says nothing about what it sounds like, but does describe my basic approach.
Nearly all the synth work on Heathen is mine and some of the piano.
I'm pretty much fully digital. I've basically spent a few painstaking days putting sounds into my laptop, just banking them, because I love playing, and I love visually seeing it on my screen and being able to change the sounds more, with different plug-ins. I've created my own synth sounds.
Orchestras are not used to playing the kind of stuff jazz musicians like to play. It requires a lot of rehearsal and recording time, so it's much easier to do on a synth or sampler. So, we came up with that idea.
