这款 AI 吉他效果器让我能定制自己的音色
I’m not sure anyone was really asking for an AI guitar pedal. But it was inevitable that someone would build one. One of the first to take the plunge is Polyend, a well-respected music gear maker with a reputation for building niche, idiosyncratic devices. The company has built grooveboxes around old-school trackers and a multi-effect pedal that you can step sequence. So there was at least some hope that if anyone could do an AI effect pedal right, it would be Polyend.
我不确定是否真的有人需要一款 AI 吉他效果器，但总会有人去开发它，这是必然的。Polyend 是首批尝试这一领域的厂商之一，这家备受推崇的音乐设备制造商以打造小众、独特的设备而闻名。该公司曾围绕老式追踪器（tracker）开发过律动盒（groovebox），也推出过支持步进音序的综合效果器。因此，人们至少抱有一丝希望：如果有人能把 AI 效果器做好，那一定非 Polyend 莫属。
Polyend’s Endless is a $299 programmable guitar pedal running an ARM processor. It’s paired with Playground, a number of interconnected AI agents that turn any text prompt into a functioning guitar effect. If you have an idea, you don’t have to hope that someone’s already built that pedal; you can simply prompt it. Maybe there’s a specific combination of effects that you’ve always wanted, but no company sells it because there’s no demand for a combination ring modulator / auto-wah. I’m not convinced this is what guitarists are yearning for, but it’s a well-intentioned first attempt to marry an effect pedal to an LLM.
Polyend 的 Endless 是一款售价 299 美元、搭载 ARM 处理器的可编程吉他效果器。它配套了名为“Playground”的系统，这是一组相互关联的 AI 代理，能将任何文本提示转化为功能性的吉他效果。如果你有一个想法，不必再苦苦等待别人开发出相应的产品，只需输入提示词即可。也许你一直想要某种特定的效果组合，但因为市场对“环形调制器 + 自动哇音”这种组合没有需求，所以没有厂商生产。我并不确定这是否是吉他手们真正渴望的东西，但这确实是让效果器与大语言模型（LLM）结合的一次善意尝试。
To be clear, the AI isn’t actually in the pedal. Instead, Polyend trained a custom LLM to code effects you can then load onto the pedal. You can also build effects yourself in C++, but most people will either download existing free Plates (as Polyend calls the effects) from the community site or prompt them in Playground. You can also pay $20 for a physical faceplate to pair with a downloaded effect.
需要明确的是，AI 并不直接运行在效果器内部。相反，Polyend 训练了一个定制的大语言模型来编写效果代码，然后你可以将其加载到效果器中。你也可以使用 C++ 亲自编写效果，但大多数人会选择从社区网站下载现成的免费“Plates”（Polyend 对效果的称呼），或者在 Playground 中通过提示词生成。你还可以支付 20 美元购买一块物理面板，与下载的效果进行配套。
Right now, the Plates gallery is home to about 60 effects, mostly developed by Polyend. They cover everything from simple saturators to tape loop simulators and guitar synths. There are even self-playing drum machines. Some of my favorites include Grunt (a lo-fi octave down effect), the Infinite Hall reverb, and Tessera (granular pitch-shifting reverb). There’s also Stardust, an enormous-sounding granular delay, reverb, and tremolo combination that would be hard to find elsewhere.
目前，Plates 图库中大约有 60 种效果，大部分由 Polyend 开发。它们涵盖了从简单的饱和器到磁带循环模拟器和吉他合成器的各种类型，甚至还有自动演奏的鼓机。我个人比较喜欢其中的几款：Grunt（一种低保真八度下移效果）、Infinite Hall 混响，以及 Tessera（颗粒音高偏移混响）。此外还有 Stardust，这是一种听起来极其宏大的颗粒延迟、混响和颤音组合，在其他地方很难找到类似的产品。
Playground is the reason most people will be eyeing Endless. It’s a web frontend for several AI agents working in tandem, trained on Polyend’s own effects library. The various AI components interpret prompts, select effect algorithms, generate code based on those building blocks, and then validate that code to ensure it will run properly without blowing out your eardrums.
Playground 是大多数人关注 Endless 的原因。它是一个网页前端，背后是多个协同工作的 AI 代理，这些代理基于 Polyend 自己的效果库进行了训练。不同的 AI 组件负责解读提示词、选择效果算法、基于这些基础模块生成代码，并对代码进行验证，以确保其能正常运行且不会震坏你的耳膜。
Generating effects costs tokens. The pedal comes with 2,000 tokens, and you can buy more at $20 per 2,000. That should be enough for a few effects. The system is a bit opaque, but the more complex an effect, and the more iterations it takes to get it right, the more tokens it costs. A simple fuzz might only cost you 20 tokens, but a granular looper with rhythmically synced glitches might cost you 500.
生成效果需要消耗代币。效果器自带 2,000 个代币，你也可以以 20 美元的价格购买额外的 2,000 个。这足够生成几种效果了。该系统的计费方式有些模糊，但效果越复杂、达到理想效果所需的迭代次数越多，消耗的代币就越多。一个简单的法兹（fuzz）效果可能只需 20 个代币，但一个带有节奏同步故障效果的颗粒循环器可能需要 500 个。
What is likely to chew through your tokens isn’t the original generation, it’s the iterating to get what you want. Especially if what you’re looking for is balanced weirdness. Trying to get Polyend’s Playground to understand the proper resonance levels for a bandpass filtered delay, or how much ring modulation you want in your evil fuzz, can be frustrating.
真正消耗你代币的往往不是最初的生成，而是为了达到预期效果而进行的反复迭代。特别是当你追求一种“平衡的怪异感”时。试图让 Polyend 的 Playground 理解带通滤波延迟所需的合适共振水平，或者你想要在邪恶的法兹音色中加入多少环形调制，可能会让人感到沮丧。
