WaivOps Lo-Fi Drums

Quick Start

from datasets import load_dataset

# Or download locally
ds = load_dataset("schismaudio/waivops-lofi-drums")

Dataset Description

WaivOps Lo-Fi Drums contains 10,000 AI-generated lo-fi drum loops from the Patchbanks WaivOps collection. All loops are in WAV format with BPM metadata encoded in the filenames. The dataset is designed for training generative audio models and for use as production-ready drum loops.

The loops were generated by the WaivOps neural drum machine, which produces lo-fi textured drum patterns with vintage character. Each loop is a complete rhythmic phrase suitable for direct use in music production or as training data for drum generation and style transfer models.

Dataset Structure

Data Fields

Field	Type	Description
audio	Audio	WAV drum loop
filename	string	Original filename (contains BPM metadata)
bpm	float	Tempo in beats per minute (extracted from filename)

Data Splits

This dataset has no predefined splits. All loops are in the default train split.

Usage Examples

Load and inspect loops

from datasets import load_dataset

ds = load_dataset("schismaudio/waivops-lofi-drums")

sample = ds["train"][0]
print(f"File: {sample['filename']}, BPM: {sample['bpm']}")
audio_array = sample["audio"]["array"]
sr = sample["audio"]["sampling_rate"]

Filter by tempo

from datasets import load_dataset

ds = load_dataset("schismaudio/waivops-lofi-drums")

# Get loops in a specific BPM range
slow = ds["train"].filter(lambda x: 70 <= x["bpm"] <= 90)
print(f"Lo-fi loops at 70-90 BPM: {len(slow)}")

Dataset Creation

Source Data

All loops were generated by the WaivOps neural drum machine developed by Patchbanks. The model produces lo-fi drum patterns with characteristic vintage texture, tape saturation, and analog-style compression artifacts.

Annotations

BPM metadata was encoded in filenames at generation time. No beat-level or onset annotations are included.

Known Limitations

• AI-generated audio: All loops are synthetically generated. While they exhibit lo-fi character, they may not fully capture the nuances of real analog drum recordings.
• Single style: The dataset focuses exclusively on lo-fi drum patterns. It does not cover other genres or production styles.
• No beat annotations: Individual onset times and drum instrument labels are not provided — only loop-level BPM.
• No standardized splits: Without defined train/test splits, users should partition the data carefully to avoid data leakage.
