DOS时代怀旧游戏最佳音质

***有个视频主8-bit guy专门做过一期视频介绍过这个玩意！原卡采集的音乐是真好听！就是太贵了……

你的这个Roland的声卡其实就是集成了MPU-401和MT-32或SC-55合成器的一体式板卡，和外接MT-32其实是一回事 ...

不对吧？我看了EN的维基百科，里面的MT-32只有你图上这一种和以下三种，其中一个我配上图了。Roland出过其他ISA声卡的。

To target computer users, Roland released a number of CM (Computer Music) modules. They came without a LCD display and had most buttons removed. CM modules are compatible with MT-32, but feature 33 additional sound effect samples which many games took advantage of. These sound effects cannot be heard on a MT-32. Early models share a similar design to MT-32 (New). Control CPU is an Intel P8098 and DAC is a Burr-Brown PCM54.

Roland CM-32L: Released in 1989, this Roland CM has only a volume knob, a MIDI message and a power-on indicator as external controls.
Roland CM-64: A combination of the CM-32L with the sample-based CM-32P, a cut-down "computer music" version of the Roland U-110. The CM-32P part plays on MIDI channels 11-16 which are not used by the CM-32L part.

有可能吧，但比如毁灭公爵呀命令与征服啊这样的游戏的时候，印象里肯定是有这个mt32的选项，因为不知道这 ...

除了外接音源，还有三种内置ISA声卡也是MT-32芯片的，但不代表所有Roland声卡。

话说当年MIDI提升印象最深的是PC版最终幻想7时候用的雅马哈软波表哈哈。

你的图1应该是LAPC-1，就是集成了MT-32和MPU-401的ISA板卡。罗兰也出过集成SC-55的板卡，应该还有SC-88的，只不过后两者已经是GM时代，即Genneral Midi，主要是90年代后期，那时基本都是PCM了，游戏也基本转到PCM音源了。

CM系列就是Computer Music，属于基于MT-32的专用于PC的外置合成器。因为需要配合PC使用，取消了MT-32的按键和液晶屏。低配的CM-32L（L代表LA，也就是MT-32的核心技术）就是MT-32加上33个专用于PC游戏的额外音源（MT-32是128个音源）。CM-64是CM-32L加上CM-32P，P代表PCM，属于过度到PCM音源的产品，CM-500则是再多了general midi的支持，拥有自家sound canvas（比如SC-55）的硬件，后面有个旋钮支持4种不同的运作模式，包括MT-32。而罗兰的SC系列的MT-32模式都是模拟的，效果不行。玩游戏要么MT-32要么CM系列，都是硬件上对游戏的最好的支持。

问个我一直搞不清楚的概念：那段时期fm和midi是如何对应的？
midi是谱的封装，最早硬件是fm来调出乐器，中期用波表来实现，后期pcm完全打包，能这样理解吗？还是完全不对

嗯，这些东西当年价格昂贵，而且咱们国内接触也很难，不像现在什么硬件都能与时俱进了。

ROLAND RAP-10 应该不属于这个系列。

个人理解，对于用FM放GM MIDI的游戏，会有一套每个音色对应FM音色的设置。这个设置可能会因游戏而不同。不过这样效果往往不怎么好。要发挥FM音源的性能还是应该直接针对FM音源进行音乐创作。
那个时期大宇的游戏就是直接针对FM音源作曲。《仙剑奇侠传》、《轩辕剑二》和《轩辕剑外传枫之舞》、《大富翁3》等世界级优秀配乐是用ADLIB VISUAL COMPOSER这套平台创作的。
而同期的《金庸群侠传》用FM放MIDI，效果远逊于直接用GM波表的。
