Tempolor v4.6
Hybrid diffusion-autoregressive architecture. Genre-aware conditioning. Up to 330 seconds. 15 credits per track.
Hybrid Diffusion-Autoregressive Core
Tempolor v4.6 combines a latent diffusion backbone with an autoregressive token prediction head, enabling simultaneous global structure planning and fine-grained note-level detail generation.
The model was trained on 4.2 million high-quality music tracks spanning 200+ genres, with explicit genre conditioning tokens that allow precise stylistic control without prompt engineering.
A dedicated emotional valence encoder maps descriptive text to a continuous emotional embedding space, producing outputs that consistently match the intended mood — from melancholic ambient to euphoric EDM.
Increased to 330 seconds with coherent musical structure throughout, including verse-chorus-bridge awareness.
Separate control over up to 8 independent instrument stems without degrading the overall mix quality.
Redesigned phoneme-to-note aligner that reduces syllable slippage by 63% compared to v4.5.
Native metronome conditioning ensures tempo stability even in complex polyrhythmic passages.
Live audio demos available after sign-up. Tracks generated in real time with Tempolor v4.6.
