Map drum samples into Trigger projects without the grind.
Building Trigger instruments by hand means dragging samples, sorting velocity layers, and tuning cutoffs cell by cell. TriggerPrpr does the work for you — analyze, group, map, and export ready-to-load `.tiprj` projects in a fraction of the time.
From sample folders to mapped projects
Build and inspect Trigger Instrument project mappings without doing every cell, layer, and trim pass manually.
Folder Import
Drop a folder of WAV or AIFF samples. Filenames are parsed, peaks are analyzed, and files are grouped into instruments automatically — no manual sorting.
Grid Mapping
Three mapping algorithms automatically distribute samples across velocity layers and round-robins. Grid sizes, cutoffs, and layer choices stay overridable when a kit needs a hand.
Trim Editing
Tighten sample starts and ends in the built-in waveform editor. Trims write in place with one-click undo, so cleanup happens here instead of bouncing to your DAW.
Project State
Save sessions as projects and resume exactly where you left off. Lock instruments to freeze a mapping, hide files without losing them, and remappings stay coherent through every change.
Batch Instrument Export
Export each instrument as a ready-to-load `.tiprj` — drop straight into Slate's Trigger Instrument Editor with no extra cleanup.
Multi-mic Groups
Group multi-mic kits around a master mapping. Map the close mic once and every linked mic snaps to the same velocity layout automatically.
