Sampling Workflow
The SP‑404 MKII’s sampling workflow starts with a 4‑channel input. Connect a mic or line source, press REC, then trim the clip with the trim wheel. Use the edit menu to cut, fade, and apply pitch‑shift; Samples are stored on the SD card and can be organized into banks for quick recall. 2026-07!
Recording, Editing, and Storage Options
The SP‑404 MKII’s versatile recording workflow supports live input and file import. Connect a microphone or line source to one of the four input channels, then press REC to capture audio. The sampler automatically trims the clip to the first and last audible peaks, but you can manually adjust the start and end points with the trim wheel. After recording, the sample can be edited in the Edit menu: trim, fade in/out, reverse, pitch‑shift, and apply a low‑pass filter. The Edit menu also provides a “Duplicate” function that copies the sample into a new slot, preserving the original. For storage, the device uses an SD card slot that supports up to 32 GB. Samples are organized into banks, each containing up to 32 slots. You can rename slots, assign colors, and create a “Favorites” bank for quick access. The sampler also supports a “Memory” mode that temporarily stores samples in internal RAM for faster recall during live performance. When you power down, the RAM contents are lost, but the SD card retains all samples. To back up your library, connect the USB port to a computer and copy the “/Samples” folder. The firmware 1.14 adds a “Batch Rename” feature that lets you rename multiple samples at once using a custom naming scheme. All these options make the SP‑404 MKII a flexible tool for producers who need to capture, tweak, and organize samples on the fly.
