Built for the room. Ready for the moment.
The chorus goes again. The band comes in early. The room settles into prayer. Keep your tracks with you.

A wider grouped transport, prominent repeat controls, and the full stem mixer.
Filter recordings, inspect stems, and choose the key and tempo before adding.
The bridge is queued while the intro keeps playing. See the destination and time remaining.
Drag any of four EQ points. Fine-tune frequency, gain and width below the curve.
A centered Mac editor keeps all four bands and both filters in reach.
Lit loop controls and a repeat counter show the active state. Fades follow the music faders.
Choose patch, key and tonality, then control pad level, fade-in, crossfade and fade-out.
Select a microphone and optional wake phrase. English recognition stays on the device.

Beta screens captured October 26, 2026. Commercial recordings and Atmosphere audio are not included with the app.
Give the worship leader room
Keep the arrangement in sight without making it a fixed destination. Repeat a section, move to the next one, or stay on a pad. Every stem follows the same transport, so one musical decision moves the whole track.
The iPad runs the full playback engine. Browse your private cloud library, choose a key and tempo, and build the set right there. Local processing replaces long cloud-render waits.
Your NAS syncs to private AWS storage. Sign in on Mac or iPad, get library access approved, then browse from anywhere. Your approved connection restores automatically. Choose key and BPM before adding each song.
Keep the original download. Process the requested performance locally, preserving drum and guide pitch and caching finished versions for reuse.
Download and check the complete set before going offline. The music plays from local files; the cloud is your library, not the live audio clock.
Use the colored song map to see where you are, choose where you’re going, and repeat it once or hold it until it’s time to move. Double-tap a section or a song card to move when the current section ends. A queued song does not wait for the whole song to finish.
Choose 1× for one extra pass, or ∞ to hold. Double-tap a destination to queue it after the current section. Move back or forward one beat to recover with the band; every stem follows the same scheduler.
View the actual screens: Section editor · Song browser · Song editor · Pad setup
Bring the keys underneath a quiet moment. Drop the drums. Lift the guide in rehearsal. Keep a separate mix for each appearance of a song in the set.
Drag four colored EQ points to shape frequency and gain with a finger or mouse. Adjust bandwidth and high-pass / low-pass filters on every stem. EQ is bypassed by default. Green EQ, yellow Solo and red Mute show exactly what is active.
Choose the key and tempo as you add a song. Processing runs locally on Mac or iPad, with prepared versions cached. Pitched instruments follow the key; drums, percussion, click and guide keep their pitch. All stems share the tempo change.
Fade music down and watch its faders follow. Fade back in to restore the saved mix, while click and guide continue. The independent ambient pad can keep sustaining.
“Prayer in C” belongs right after the last song.
Add a named Atmosphere pad entry, with or without click. The pad fades in during its guide count-in, while click and guide stay clear. New pad entries then loop indefinitely. Release the moment with a two-measure fade at its tempo, or transition into the next song.
Uses your existing Atmosphere soundpack. Commercial audio is not bundled.
Keep originals on your NAS and sync the library to private AWS storage. Browse and download on Mac or iPad away from home, without a VPN or a Mac export. Complete downloaded performances play offline.
Search by title, artist or album. Filter by key, tempo, source and locally prepared availability, then sort by the detail you need.
Choose key and tempo as you add a song, then edit them from its card. Stopped selections prepare automatically. Add a pad from the same playlist tile.
Choose Stop, Auto-link, Overlap or Crossfade. Prepare the next entry in advance and see when it is ready.
Use section repeat, beat correction and music fade as the set unfolds. Selection and preparation stay silent until you press Play.
Inside the current Mac + iPad beta
One place for the library, the arrangement and the mix.
Built in the open. Tested in stages.
KT Multitracks is in active development. Mac and iPad TestFlight builds are available for invited testing through Kulinich Tech. Version 0.15.3 (40) is approved for external testing on both platforms. There is no public installer or announced pricing.
macOS 13+ · iPadOS 17+
Tested on Apple silicon Mac and iPad Pro
Your own licensed audio library
These are development directions, with no release dates promised.
Mac uses outputs exposed by Core Audio drivers, including installed network-audio drivers; iPad uses speakers or compatible USB interfaces. Channel-name suggestions use names exposed by the selected driver; automatic console-network discovery is not available. SoundGrid/LV1 and Dante live-rig acceptance remain pending. ProPresenter indicators report API/MIDI availability, not verified cue delivery. Rehearse voice recognition, routing and transposed material with your own rig.
A few practical things
On Mac, open Settings → Library → Load practice library, then add KT Practice Session. On iPad, download the original practice package, unzip it in Files, then import the extracted KT-Practice-Demo folder from the app’s library and add the song. Both use three original synthesized stems and five reviewed sections at 120 BPM; no account or commercial recordings are needed.
No. Bring multitracks and pad samples you are licensed to use. The preview indexes your library and prepares local playback audio. It does not grant rights to third-party recordings or soundpacks.
Supported ZIP song packages can stay zipped. The player indexes their contents, then prepares verified local audio for playback. Originals remain on the NAS.
Yes. Key preparation follows each stem’s pitch policy. Pitched instruments follow the selected key; drums, click and guide stay fixed. Ambiguous loops and tonal percussion need review before transposition.
Yes. Set the performance BPM for that playlist entry. The player processes every stem together with pitch-preserving tempo adjustment, keeping their shared timeline aligned. Source tempo changes and section beat positions scale proportionally. Rehearse the result with your actual tracks before using a new tempo live.
Choose Original, Classic, Blip, Cowbell, Gentle, Percussive, Saw or Woodblock in global Click settings. It applies to song click stems and pad clicks while stopped. For songs, replacement clicks retain the source’s actual pulse positions and gaps rather than rebuilding a guessed constant-tempo grid.
Yes. An authorized Mac or iPad can browse the private AWS library without a VPN, choose key and tempo, and download songs directly. Key and tempo processing happens on that device. A complete downloaded performance can play offline; uncached songs still require a connection.
Yes. The iPad beta has its own synchronized playback engine and the same layout, mixer, loops, section controls, pads and voice settings as Mac. Use iPad speakers or a compatible USB audio interface. Stereo music with independent click and guide needs at least four output channels. Native SoundGrid drivers on iPad are not available in this beta.
Enable on-device English recognition, select a microphone and optionally require Lets, MT, AI, Vasiya, Jesus, Max or Hey first. Commands such as “repeat bridge” and “go back to verse one” resolve to the reviewed song map. Section count-ins play over the final beats of the current section, without inserting a bar. Voice is optional and needs microphone/speech permissions and an available on-device English model.
Register in the app, verify your email, then sign in. A library administrator must approve access before you can browse or download private recordings. Registration and TestFlight access do not grant rights to someone else’s audio. The new beta account flow includes password reset, sign-out, account deletion, and personal activity history. The first live owner-registration and admin-approval walkthrough is still being validated.
Successful account logins and songs played are associated with the signed-in user. Administrators can review that history and manage library access. Cloud history is retained for one year; microphone audio and voice transcripts are not included. See app privacy for details.
