How to use Chppr

Quick start

1. Add audio. Drop a file, record audio, capture browser audio, or load the demo sample.
2. Choose a source region. Find the drum break, vocal phrase, melody loop, or texture you want to test.
3. Press Slice. The selected region becomes chops on the active track.
4. Play the pads. Check whether the chops feel like an instrument before spending more time on the idea.
5. Sequence or export. Build a loop in the sequencer, export WAV, save a project file, or publish a share link.

Screen map

The easiest way to understand Chppr is to separate the app into three ideas: sources, tracks, and workflow panels.

Tracks and sources

This is the mental model that prevents most first-use confusion.

Source

The original audio you add to Chppr. It can be an uploaded file, a recording, captured browser audio, or the demo sample.

Track

A working layer. Each track stores its own source selection, sliced region, pads, pattern, pitch, and playback settings.

Track A-D

Four layers for sketching a beat. You can keep one track simple, then use another track for a different source or a different chop idea.

Sources view

The source icon opens a list of loaded sources. It is useful when you want to add, preview, remove, or check which tracks use a source.

Slice, pads, and sequencer

These three areas are one workflow, not separate features. Slice first, play the result, then arrange a pattern if the chops are working.

How to slice

1. Pick the active track at the top of the app.
2. Choose a source from the source selector.
3. Select the useful region on the waveform.
4. Press Slice to assign the region to the active track.
5. Adjust slice points, add or remove cuts, normalize if needed, and reslice when the feel changes.

How to play pads

After slicing, open the pads panel. Each pad triggers a slice from the active track. This is where you check whether the sample feels good under your fingers before sequencing it.

How to sequence

Open the sequencer panel after a track has slices. Add steps to trigger pads over time. Use this to sketch a loop, then export patterns if the sequence itself is worth keeping.

Using multiple tracks

Tracks do not have to mean finished song stems. They are lightweight scratch layers. You can use them for different roles while you test an idea.

• Track A: drum break or main groove.
• Track B: vocal chop or short hook.
• Track C: melody loop, texture, or field recording.
• Track D: alternate chop, extra percussion, or a quick comparison idea.

If a track has no slices, the pads and sequencer for that track will be empty. Switch back to the slice panel and create slices for that active track.

Save, export, and share

Chppr has several outputs because different moments need different files.

Save project

Downloads a Chppr project file so you can reopen the session later. This is local and does not require an account.

Export slices

Downloads the chopped pad sounds as WAV files. Use this when you want to bring one-shots into Ableton, FL Studio, Logic, or another DAW.

Export patterns

Downloads sequenced loops as WAV files. Use this when the pattern is the part you want to keep.

Share project

Creates a browser-playable link by packaging the project and saving it to cloud storage. Only publish audio you have the right to distribute.

Local audio is processed in your browser while you work. Audio is packaged and uploaded only when you publish a share link. Some remote sources cannot be bundled yet; if sharing fails, try an uploaded file or the demo sample.

Open Chppr and export an idea

BeatArc, Key Sync, and Sources

After the basic slice-to-pad flow makes sense, these views help you shape or manage the idea.

Mobile guide

Chppr works best when you treat mobile as a quick sketch surface. Add audio, slice a small region, swipe through the lower panels, and use pads or the sequencer to test the idea.

• Use shorter regions first. Long files are harder to manage on a small screen.
• If you cannot see pads or the sequencer, make sure the active track has slices.
• Use Save project before leaving if you want to keep editing later.
• If you need detailed arrangement, export WAV and finish the idea in a DAW.
