Hi, I'm considering investing in midi for FX and eclectic sound pallet for my Chapman Stick (12 string bass and melody) instrument. But I have no idea what processors or synths I would need to get the sounds I want. Should I go with rackmt. synth boxes? or computer-based? for long-term flexibility, ease of use, quality of sounds and live performance. Please email me if you can offer suggestions. Thanks in advance. -Qua
