请问E-MU 0404和ESI U46 XL哪个usb音频接口好？

看网站的硬件规格，E-MU 0404 USB完胜，而且它技术规格参数很全，看起来更专业一些

K歌的话，0404音频不好路由。

为什么没有人做一个对比呢？

各有千秋，k歌的话ESI支持多驱动跳线，可以网络和软件一起共享驱动，但0404不能，但我还是喜欢0404，没什么理由，各有所好。

0404 K歌 没问题的

U46可以软跳线，自由调整各种输入输出，而且现在国内服务做得不错，有客服解答还有QQ技术群呢

U46就只能录音，如果做MIDI的话，一塌糊涂，ASIO性能极差

我也想用0404，有没有人能给发个0404的驱动界面？如果和1212m差不多，可以用send发送，就可以内录的。

网上几乎所有介绍里都说0404可以USB供电，但是官网上好像没有说。而且我听有用过的人说，拔掉电源就不能用，必需接电源。到底是怎么回事？

更正一下：0404 控制面板不带 Patchimax DSP    ，不知道这是为什么！ 网络K歌挂VST 不合适。
