What's New in GranSample

1.6.0

October 24, 2026

v1.6 — every track in one grid, a beat that keeps playing in other apps, and factory sounds at their true pitch. • TRACKS — tap the grid button next to the gear and the pads make way for all 16 tracks' steps. Tap a cell to turn a step on or off, drag across to paint, drag up or down to set velocity. Tap a track number to select it; hold it to play the pad. iPhone pages tracks 1–8 and 9–16; iPad shows all 16 when they fit, and pages them when they don't. Tracks 9–16 need Pro. In SONG mode the grid is read-only. • BACKGROUND AUDIO — turn it on in Settings (gear) → Audio and a playing pattern keeps going after you switch apps or lock the screen, mixed with the other app's sound. MIDI from a keyboard or another app keeps playing your pads too. Off by default, and free. After 10 minutes in the background with no sound and no MIDI notes or controller moves it stops by itself. The mic never runs in the background. It doesn't follow MIDI clock or Link: to play in time with a host such as AUM, use the GranSample plugin. • INTERNAL SEQUENCER — each project now has an INT SEQ switch in the step sequencer, on by default. Off, SEQ and SONG don't start the patterns, and MIDI from a keyboard or another app still plays the pads. The plugin's Sequence tab has the same switch: off, your host's play and stop leave the pattern alone. The switch is saved with the project, and with the host session in the plugin. • FACTORY SOUNDS AT THEIR TRUE PITCH — on 48 kHz devices (most current iPhones and iPads) the factory sounds played about a semitone and a half sharp and 8% short. They now play at their true pitch and length, in the app and the plugin, so projects built on them sound lower and may need a retune. Samples loaded in the plugin now play at their own pitch too: on a 48 kHz device a 44.1 kHz file plays about a semitone and a half lower than before and a 96 kHz file an octave higher, so host sessions may need a retune. • LOAD MENU — Load offers the factory samples (Drums, Instruments, Textures) besides your files, in the app and the plugin. The plugin refuses files over 60 seconds, as the app does. • PLUGIN PRESETS — the plugin's ten Scenes now appear in your host's preset menu. • SAVE AND REVERT — Save Project saves over the project you loaded. The revert button always asks first: Revert to Last Saved, Revert to Original Kit or Discard Draft. New Empty Project starts truly empty. • CHROMATIC MODE — a sample loaded, recorded or chopped onto a pad while chromatic is on is kept for when you turn it off. A new sample on the root plays across all 16 pads; clearing the root turns chromatic off. • Fixed: a tuned pad keeps its Tune when played from MIDI; LFO settings are saved; SEQ plays the pattern on screen, not the last one you edited; painting steps is smoother. • Fixed: after a chop, each slice plays with the chopped pad's volume, tune, envelope and other settings at once. Before, it kept those of the pad it replaced until you reopened the project. • Fixed: Share Kit keeps your own sample on a pad named like a factory sound (such as Kick), and no longer fails with "sample file could not be found" for older projects. • Fixed: importing a kit warns about locked pads only when it has sounds on pads 9–16. It used to warn about any kit on more than 4 pads. • Fixed: the plugin holds up better when a host reopens a session or loads a preset while its window is open. • Fixed: the home screen fits every iPad in portrait, and the Pro screen's buttons stay on screen on the iPhone SE and iPad. On iPad, prompts show all their buttons, including Cancel. • Fixed: the What's New screen stays away once you swipe it down.

It's been solved on 1.4.3. Cheers!

Thank you have a blessed day in God and self on purpose.

Response from developer

Sorry for the trouble — you were right about both, and both are fixed in 1.4.1 (has already been sent to App store). Loading your own samples was broken and failed silently, worst of all from the GranSample folder in Files. The plugin window was separate: some hosts ask which window sizes a plugin supports and GranSample answered "none" — AUM never asks, which is why it was your one working setup. Email me at zhiii0x@gmail.com and I'll put you on TestFlight before it ships if you want. Thanks for the note at the end. It landed.

Not fit for purpose

As the title says. No response from developer.

Response from developer

Thanks for your feedback. Already back to you with email, and issue been solved on 1.4.1 :)

I want to love this

I get only 2 screens.. 16 pads with 6 cut in half, and a mixer. No record, nothing.. I have tried maximizing, nothing seems to give me access. I paid for a pro version.. still nothing. I’m using an iPad m5 13 2tb
Update: The developer contacted me, and was very understanding.. That is rare on here! I will definitely give it another shot!

Response from developer

Hi Rick, You're right — I didn't specifically design the app for iPad at first, so the UI ends up limited like that. The next version has major updates and should be live in the next 2-3 days once Apple approves it. Hope you give it another try then!
