Tapko

Tapko is a fast, no-nonsense drum sampler built by a musician for musicians. Load your sounds, build your kit, and play — standalone or as an AUv3 plugin in your favorite host.

Use Tapko on its own as a playable drum machine, or load it as an AUv3 instrument in AUM, Loopy Pro, GarageBand, Cubasis, and more.

16 PADS, TOTAL CONTROL
• 16-pad grid with per-pad sample import (WAV, AIFF, MP3, M4A, FLAC, CAF)
• Per-pad 3-band EQ with adjustable gain and frequency, volume, pan, gain, choke groups, and configurable Fade Out
• Swipe pads to tweak volume, EQ, pan, and reverb send on the fly
• MIDI Learn — tap a pad, play a note, instantly assign note and channel
• Swipe left/right on single-sample pads to cycle saved versions
• Built-in stereo reverb with per-pad send, per-pad dry level, and global room/decay/wet-level controls
• Built-in delay/echo with per-pad send and global time, feedback, damping, and wet-level controls
• Per-pad varispeed pitch — retune a pad up or down, turntable-style
• Let a pad's hits overlap and ring out instead of cutting each other off — perfect for cymbals and pads

ADVANCED SAMPLING
• Velocity layers — up to 5 layers per pad with adjustable velocity ranges
• Round robin — cycle through up to 5 samples per pad (sequential or random)
• Layer mode — stack up to 5 samples per pad and trigger them simultaneously
• Random velocity — override incoming velocity with base +/- variation for natural dynamics
• Sample Editor with zoomable waveform: high-detail zoom view above, full-file overview below with a draggable zoom-window and in/out markers, pinch-to-zoom, trim handles, start delay, attack, and per-pad gain
• Global media browser — import clips once, assign to any pad in any kit; organize into folders, multi-select to move or delete, and export/import your whole library as a single file

KITS & SHARING
• Create, rename, duplicate, and delete kits
• Import and export kits as .tapkokit files
• Kit Store — browse and download free community kits
• Full backup and restore of all kits and media to a single .tapkobackup file
• iCloud backup — upload your kits and Media Library and restore them on another device, with live progress and a clear confirmation once everything is in iCloud
• Build kits on your computer at tapko.davidguva.se

MULTI-OUTPUT ROUTING
• 9 stereo output buses (1 Main + 8 Aux) for hosts that support multi-output
• Assign each pad to an individual output bus for separate mixing and effects
• Pads assigned to an Aux bus are isolated to that bus, so you can send drums to individual channel strips without duplicating them on Main
• Single-output hosts hear every pad that's still assigned to Main
• Pads routed to an Aux bus show which output they use right on the pad

MIDI & HOST INTEGRATION
• MIDI input with customizable note mapping (GM drum layout by default)
• Per-pad MIDI channel assignment (omni or channel 1–16)
• MIDI output and Program Change for kit switching
• All parameters exposed to the host for automation
• Delay syncs to the host's tempo
• Factory presets support

BUILT FOR PERFORMANCE
• Real-time C++ DSP engine with vDSP acceleration
• 48-voice polyphonic playback with intelligent voice stealing
• Efficient CPU usage for most kits; usage increases with kit complexity (more layers, longer samples/tails, and heavier FX/routing)

STANDALONE & PLUGIN
Tapko works as a standalone drum machine right out of the box. It also registers as an AUv3 instrument plugin so any compatible host can load it.
