TART: A Modular Tool for Technique-Aware Audio-to-Tablature Guitar Transcription

TART is a modular four‑stage pipeline that transcribes guitar audio into tablature, addressing key limitations of existing systems such as missing expressive techniques, incorrect string‑fret assignments, and poor performance on noisy recordings. The stages include an audio‑to‑MIDI model, an expressive technique classifier, an audio‑conditioned T5 encoder‑decoder for string‑fret mapping, and an automated tablature generator. In zero‑shot evaluations on GuitarSet, EGDB, and noisy variants, TART outperforms prior baselines with significant gains in audio‑to‑MIDI, string‑fret, and end‑to‑end tablature metrics.

Fretiq: Browser-Native Electric Guitar String Classification via Engineered Spectral Features and Held-Out Free-Play Evaluation

arXiv:2607. 18303v1 Announce Type: cross Abstract: Identifying which string produces a given pitch in monophonic electric guitar audio is a fundamental classification challenge: a single pitch can often be produced on multiple strings at different fret positions, with timbral differences that prior listening studies confirm are largely imperceptible to untrained humans.

TUTTI: Toward generalizable audio-to-score transcription via fully synthesized data

TUTTI is a new pre‑training framework for audio‑to‑score transcription that uses a large, fully synthetic multi‑instrument dataset generated by a symbolic music model. The approach trains a standard Transformer encoder‑decoder on these synthetic audio‑score pairs, producing a stronger foundational representation than single‑instrument training. When fine‑tuned on real datasets, TUTTI surpasses prior methods, achieving state‑of‑the‑art results and demonstrating strong cross‑instrument transferability.

Pianist Transformer: Towards Expressive Piano Performance Rendering via Scalable Self-Supervised Pre-Training

arXiv:2512. 02652v2 Announce Type: replace-cross Abstract: Existing methods for expressive music performance rendering, a conditional generation task that aims to generate a human-like performance from a symbolic score, rely on supervised learning over small labeled datasets, which limits scaling of both data volume and model size, despite the availability of vast unlabeled music, as in vision and language.

Synthesis and editing of multi-instrument audio mixtures using scalar-quantised latents with MIDI Span conditioning

SpanSynth-Edit is a flow‑matching model that enables MIDI‑guided synthesis and editing of multi‑instrument audio mixtures using low‑frame‑rate scalar‑quantised latents. It encodes instrument‑labelled note lifecycles as unordered event sets, pools them into a conditioning vector per audio‑latent frame, and uses contextual audio for instrument‑specific timbre guidance. The model supports editing by resynthesising target regions from revised MIDI and demonstrates competitive performance on single‑ and multi‑instrument benchmarks, including within‑frame onset control.

CPR: Combining global composing, local performing and full-sequence refining in piano rendering with continuous autoregressive modelling

The paper introduces CPR, a piano rendering framework that combines continuous autoregressive modeling with local flow matching and full‑sequence refinement. It predicts continuous hidden states, generates 24 kHz acoustic latents, and upsamples to 48 kHz, while new techniques BREPA and MT‑RoPE enhance musical semantics and cross‑modal alignment.
