A friend is interested in an arranger but wants one that has possibilities to modifiy sounds like a synthesizer.

He has used a Triton, and is now considering either the Motif, Studio, or used K2500. But likes the arranger portion of my SD-1. He says the saounds are great meat and potatoe sounds, but noticed orchestra sounds were better in the other keyboards, the organs were better, the guitars were extremely better.

As for the synth sounds he said they were ok for fill but he needs more

any suggestions?
