• intros：{"brand_intro":"Roland是日本电子乐器巨头，成立于1972年，创始人梯郁太郎被誉为'电子乐器之父'。Roland在合成器、鼓机、效果器领域拥有无数经典产品（如TR-808、TB-303），是全球音乐设备行业的标杆。品控理念强调'创新与可靠'，产品经久耐用，二手市场流通量大。Roland的MIDI控制器以手感出色、兼容性广著称，是专业录音棚的常客。","product_intro":"Roland A-49是Roland入门级MIDI键盘控制器，定位家庭录音与移动创作。核心卖点：49键全尺寸键床（带触后）、Roland独有的'SuperNATURAL'音色引擎（需配合Roland音源）、USB供电。适用场景为编曲、音色控制、现场演出。相比AKAI MPK Mini，其优势在于键床手感更接近真实钢琴，且支持触后，适合需要细腻演奏的用户。","key_specs":{"键床类型":"49键全尺寸，力度感应带触后，手感接近真实钢琴","控制器数量":"1个推子、2个旋钮、走带控制键（较少，强调简洁）","屏幕":"无屏幕，通过LED灯反馈状态","连接方式":"USB供电与数据传输，MIDI输出/输入","软件生态":"附赠Roland Cloud试用版、Ableton Live Lite、Studio One Prime"}}
