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, reverb send, and delay 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
• Tapko Space reverb — Room, Plate, Hall, and Cosmos, with Space, Decay, Pre-delay, Color, Clarity, and Modulation, plus per-pad send and dry level
• Tapko Space delay — Clean, Warm, Diffuse, and Reverse, synced to your host's tempo (straight, dotted, or triplet) or free-running, with the option to send its echoes into the reverb
• Reverb and delay presets — drum-focused factory presets plus your own, in every kit. Export and import them; shared kits sound the same anywhere
• Varispeed pitch — retune a pad up or down turntable-style, or set pitch per velocity layer and round-robin sample
• 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 a zoomable waveform and full-file overview, trim handles, start delay, attack, and gain. Play sounds exactly like hitting the pad
• Render Pad — bounce a pad, with its trims, EQ, pitch, envelope, and layers (and optionally its reverb and delay), into a new sample. Save it to the Media Browser or put it straight back on the pad
• Global media browser — import clips once and use them in any kit; nested folders, folder import, multi-select, and library export/import

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, media, and effect presets to a single .tapkobackup file
• iCloud backup — upload kits, media, and presets and restore them on another device. Later backups only upload what changed
• 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
• Pad parameters and the Mixer (main volume, reverb, delay) exposed to the host for automation
• Delay syncs to the host's tempo
• Reports its reverb and delay tails to the host, so they ring out after the last hit
• 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; heavier kits (more layers, longer tails, more FX) use more

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.
