Pith's one-line read This paper argues that explainable AI for artists should make neural audio models into hands-on design materials, not just transparent black boxes.

The pith
A machine-rendered reading of the paper's core claim, the machinery that carries it, and where it could break.
The reading
What carries the argument
The load-bearing artifact is Latent Terrain, a toolkit of Max/MSP objects that maps the latent space of a neural audio autoencoder into a 2D control space and places it inside a visual programming environment. The latent space is the compact, learned representation an autoencoder uses to compress and reconstruct audio—normally treated as opaque and hard to navigate. Surrounding the toolkit are video tutorials, documented APIs, example patches, an open repository of autoencoders, and a project showcase. Conceptually, the engine is the idea of material agency: a model's properties emerge through use, so explainability means giving artists resources to probe, configure, and hack the model rathe
What would settle it
A matched-group study in which musicians with similar backgrounds build a musical interface with a neural audio model either through the full Latent Terrain package (toolkit, documentation, tutorials, community) or through a bare API and a technical paper; if the bare-API group develops comparable musical interfaces and reports comparable understanding, the central claim loses its support.
Extended reading notes
Core claim
On the paper's own terms, the central discovery is that a deliberately assembled ecology of software, documentation, tutorials, and community exchange—what the authors call material explainability—can let artists develop a working, tacit understanding of a neural audio model's latent space. The paper documents Latent Terrain, a package of Max/MSP objects that maps an autoencoder's latent space to a 2D control space, alongside an online repository of docs and tutorials and a community showcase. Four artists contributed projects ranging from a virtual gallery to a live performance system, a meditation sonification, and an ambient soundtrack. Their reflections emphasize learning through trial-a
Load-bearing premise
The paper's case rest on the four invited artists being representative, and on their positive reflections being caused by the material-explainability package rather than by the novelty of the tools or the curated community environment.
Editorial extensions
If this is right
- XAI for creative practice should produce tools and resources that make models modifiable and integrable, not just explanations of how they work.
- Artists can acquire operational understanding of opaque neural models through iterative crafting, trial-and-error, and embodied listening.
- Documentation and tutorials written for creative practitioners in their own environments lower the barrier to hands-on engagement with AI.
- Community spaces where artists share domain-specific techniques sustain long-term engagement with AI materials.
- The latent space of a neural audio model can serve as a design material with its own grain, resistances, and propensities.
Reading between the lines
- The material-explainability pattern likely extends beyond audio: the same toolkit-plus-documentation-plus-community recipe could be tested with diffusion models, LLM fine-tuning, or visual generative models in creative settings.
- If the claim is right, evaluation of XAI for artists should shift from measures of comprehension to measures of sustained practice, reuse, and the range of artifacts produced over time.
- A stronger test would separate the ingredients: do artists succeed because of the toolkit itself, the documentation, or the curated community? The paper's case study does not isolate these factors.

Referee Report
Summary. The paper proposes 'material explainability' as a range of activities and artifacts that make AI models accessible, inclusive design materials for artists. It presents Latent Terrain, a Max/MSP toolkit for exploring latent spaces of neural audio autoencoders, together with online documentation, video tutorials, pre-trained models, and a website for artist project showcases. Four invited artists contributed projects; excerpts from conversations with them are used to reflect on how the artists learned the models through trial and error. From this case study, the paper derives three recommendations for XAI design in NIME: make visible how AI models can be tailored into artistic assemblages; enable learning through crafting; and foster community exchange of techniques. It concludes that material explainability supports hands-on artistic explorations of neural audio models.
Significance. If the conclusion can be backed by stronger evidence, the paper would be a valuable operationalization of the XAIxArts manifesto's call, providing a concrete open repository and detailed documentation in a domain where material-oriented XAI has been mostly conceptual. Strengths include the public Latent Terrain toolkit, the range of supported autoencoders, and the plural artist projects that give texture to the notion of material understanding. The central weakness is that the evidence is limited to four self-selected, curated positive cases, so the causal or enabling role of 'material explainability' specifically remains undemonstrated. As a design case study and a set of design recommendations, it is useful; as support for the stated conclusion, it currently overreaches.
major comments (3)
- [§3.3, §5] The central claim in §5 that 'the material explainability approach supports hands-on artistic explorations' is stronger than the reported data. §3.3 describes four artists who 'shared a mutual interest' and were invited/showcased on the authors' site; the quotes are from 'our conversations' with those artists. No recruitment criteria, interview protocol, analysis method, negative cases, or comparison condition are reported. The intervention bundles a new toolkit, documentation, tutorials, pretrained autoencoders, authorial attention, and community curation, so the observed explorations cannot be attributed to material explainability as opposed to generic usability, novelty, or artist expertise. The paper itself calls the project 'a heuristic' in §3; I recommend either adding methodological detail and explicit discussion of alternative explanations, or limiting the conclusion to 'illustra
- [§4] The three recommendations are presented as grounded in the four projects, but the link between the evidence and each recommendation is loose. For example, the first recommendation claims that making visible how AI models can be tailored enabled the iterative integration of materials; yet none of the artist quotes in §3.3 identifies a specific feature of the Latent Terrain toolkit, documentation, or tutorial that created this visibility. Similarly, the second recommendation's 'tacit understanding' is asserted rather than demonstrated by an analysis of artist behavior or verbal reports. Please map each recommendation to observable evidence (e.g., which artifact was used, what changed in the artists' practice over time) or explicitly present the recommendations as design lessons needing further validation.
- [§2.3, §5] Material explainability is defined broadly as 'a range of activities or artifacts' (§1) and is noted in §2.3 to have been 'raised' in the authors' own XAIxArts Manifesto [7]. The breadth of the definition makes it difficult to falsify: almost any tool, documentation, or community activity could count. As such, the conclusion that the approach 'supports' artistic exploration risks being circular unless the paper specifies (a) what distinguishes material explainability from ordinary toolkit development and community building, and (b) what evidence would count against the approach. Please clarify the relationship to [7] and to earlier 'understanding in action' work [13,30,37] so that the contribution is clearly delimited.
minor comments (5)
- [§4] 'ocio-material environments' appears to be a typo for 'socio-material environments'.
- [§2.2] 'around the edges explanations' is quoted but not defined; please briefly explain what actions or insights this type of explanation affords.
- [Abstract, §2] 'XAIxArts' is used without expansion; spell out 'Explainable AI for the Arts' at first use.
- [§3.3, Fig. 3] Clarify whether the shared repository contains source code/patches or only descriptions and media; the claim about a 'repository of resources' is stronger if the artifacts themselves are available.
- [Throughout] The styling 'RA VE' is inconsistent; use 'RAVE' or the accepted typography for the model name.
Circularity Check
No significant circularity: the paper is a qualitative case study; self-citations are contextual and the central claim rests on empirical evidence rather than definitional reduction.
full rationale
The paper contains no equations, fitted parameters, or formal derivations. The central notion 'material explainability' is defined in general terms in Sec. 1 as 'a range of activities or artifacts that aim to transform AI models into accessible and inclusive design materials' and is applied through the Latent Terrain case study. While the paper acknowledges a similar notion was raised in the authors' own XAIxArts Manifesto [7] (Sec. 2.3), the definition is independently stated in Sec. 1 and grounded in external literature on the material turn, Scurto et al., and Wiberg, among others. The toolkit is attributed to the first author's prior doctoral work [45], but that is contextual background, not a load-bearing justification for the paper's claim. The conclusion that 'the material explainability approach supports hands-on artistic explorations' (Sec. 5) is an empirical claim based on observed artist projects and self-reported reflections in Sec. 3.3; it is not a notational consequence of the definition. The paper explicitly hedges its contribution as 'a heuristic for further work' (Sec. 3), acknowledging the case study's limits. Potential threats about curated participation and lack of control conditions are external-validity concerns, not circularity. No specific step reduces to its own input; the self-citations present are not load-bearing, yielding a low score.
Assumptions & free parameters
assumptions (4)
- domain assumption The material-turn/material-agency lens applies to AI models as design materials.
- domain assumption The barrier to using neural audio models in NIME is primarily a lack of accessible resources and explainability, not other factors such as cost, hardware, or aesthetic preference.
- domain assumption The four artist projects and their quotes are representative of artists' experiences with the toolkit.
- domain assumption The XAIxArts Manifesto's call for material explainability [7] is an accepted starting point.

Recent work in Human-Computer Interaction (HCI) increasingly treats AI models as design materials that have distinctive computational properties to shape design artifacts. Artists learn to work with the model "at play" to explore their emerging properties. The aim of explainability, in this view, is to make visible a crafting and hacking space to enable sustained creative practices with AI. In this chapter, we propose material explainability as a range of activities and artifacts that transform AI models into accessible and inclusive design materials in the workspace of artists, designers, and makers. We present a case study of building a repository of resources to enable artistic explorations of neural audio models in New Interfaces for Musical Expression (NIME) design. Reflecting on our community-building journey and the making of a collection of musical interface designs with a group of artists, we raise three recommendations on enabling the exploration of AI as materials in artistic practices to inspire future XAI design for artists.
