Files

file	what
dit_fp16_ext.onnx + dit_fp16_ext.bin	diffusion transformer, float16 weights, external data
cozucu.onnx	autoencoder decoder (latent → 44.1 kHz stereo)
istemler.bin / istemler.json	precomputed prompt conditioning + metadata, base package (kick, snare, closed hi-hat, styles)
dit_perk_fp16_ext.onnx + dit_perk_fp16_ext.bin	fine-tuned diffusion transformer: percussion, tom set, open/half/pedal hi-hat, rimshot/brush snare (float16)
istemler_perk.bin / istemler_perk.json	precomputed prompt conditioning + metadata for the percussion package

Inputs

DiT: x (1,64,43), t (1), cross (1,65,768), glob (1,768) → v (1,64,43). Decoder: z (1,64,43) → (1,2,88064). Sampler: 8-step ping-pong, t = sigmoid(-linspace(-6, 2, 9)), t[0]=1, t[8]=0; d = x - t_i·v, x = (1 - t_{i+1})·d + t_{i+1}·noise.
