Perhaps the oldest and most storied genre of entrant in this list, MIDI foot pedals have existed in some form or another since the final days of the hair metal era. A traditional setup involves a rack mounted switcher, which has five or more loops in which a guitar tech would place an analog pedal like a Tube Screamer or a Big Muff. The rack lurks in the shadows of the stage behind the wall of amps, untouched by the guitarist. Said guitarist then stomps on a foot controller up front to send MIDI Program Change (PC) messages to the switcher, telling it which loops to engage and disengage. One button enables or disables an infinite number of effects, making it much easier to focus on more important tasks like playing guitar, chugging Jack Daniels, or glaring menacingly at your guitar tech.

角色扮演不会让 AI 变得更聪明、更有知识、更准确。它做的事情更像是一个遥控器——调的是频道，不是信号强度。 你用身份设定选定了一个「频道」（科普作者、年终自评教练、文学评论家），模型就会在这个频道的风格空间内输出。如果这个频道恰好是你需要的，效果立竿见影；但如果你用它来「增强信号」（提高事实准确性），不仅无效，还可能制造更隐蔽的噪声。，这一点在新收录的资料中也有详细论述
