Preparing Samples for Elektron Octatrack

The Elektron Octatrack MKII is a powerhouse performance sampler — but its 1 GB Flash storage and per-track RAM constraints mean you need a well-organized sample library. Here is how to prep your WAVs for maximum Octatrack mileage on macOS.

Octatrack Audio Format

The Octatrack supports both mono and stereo samples natively, in 16-bit or 24-bit WAV format. Unlike the Digitakt, you can choose — but each choice has trade-offs.

• Format: WAV (uncompressed) or AIFF
• Channels: Mono or stereo
• Sample rate: 44.1 kHz native
• Bit depth: 16-bit or 24-bit

When to Convert to Mono

Stereo files take twice as much storage and RAM. For most performance use cases — drum hits, one-shots, percussion, vocal chops — mono is the right choice on Octatrack:

1. Double your sample slots: 1 GB Flash holds twice as many mono samples as stereo.
2. Save Flex Machine RAM: Each track loads samples into limited RAM — mono frees up space for longer sample times.
3. Cleaner performance: Mono samples are easier to position in your live mix using the Octatrack's track-level pan.
4. Keep stereo for atmospheres: Pads, ambience, and stereo loops still benefit from full stereo width.

Batch Convert Your Sample Library

If you have folders of drum hits, percussion, and one-shots you want to mono-fy for the Octatrack, batch convert them all at once:

1. Download It's mono, yo! from the Mac App Store
2. Drag your drum/one-shot folder into the app
3. Set Output Settings to WAV / 16-bit / 44.1 kHz for native Octatrack compatibility
4. Pick an output folder (e.g. "Octatrack Mono")
5. Hit Convert, then copy the folder to your CompactFlash card or use Octatrack Project Manager

Octatrack Sample Prep Tips

• Use 16-bit for drums and one-shots — the Octatrack's effects sound fine at 16-bit and you save 33% storage vs 24-bit.
• Reserve 24-bit for important melodic loops where dynamic range matters.
• Use It's mono, yo!'s proper stereo summing — the Octatrack respects what you give it.
• Organize samples in folders matching your project structure before transferring — moving things around later is tedious.
• Pre-trim silence in macOS so Static and Flex machines have minimal latency.
