back to the topic, I also think an OT2 is not a real need, but it would be nice, would it not?
midi scenes, more complex arranger with automations, moar mangler effects à la Gotharman, more open mind project management, scene controlable pickup machine tracks, OB feature, USB host, maybe some stem bouncing batch processing (OB?)...
anyway if OT2 never comes out, I agree OT1 is still the most incredible and powerful sample machine for composition and live gear!! I can imagine me still using it 10 years from now!
