Changelog

All notable changes to EP-PatchStudio.

1.4.3

Latest

Fixed

Fixed
  • macOS: if the app gets stuck flashing black and white at launch, it now recovers on its own. The first failure reloads quietly. If that does not take, it asks before setting the broken browser data aside and restarting. Reinstalling never cured this because the bad data lived outside the app
  • Startup no longer loads every stored project, sample pack and cached sample into memory at once. Big libraries open faster, and the launch crash some of you saw after a device factory reset should be gone
  • Android: backing up a full device no longer crashes at the final step when the archive is large
  • Triggering the same note twice in quick succession no longer leaves a looping voice playing in the background
  • Device Info refreshes its storage and sample counts each time you open it, so the figures settle after a format. The device reclaims space slowly, so give it a moment

New

New
  • Settings > Storage has a Rescan Library Storage action. If the app's database is ever lost, it rebuilds your projects, sample packs and backups from the audio files still on disk

1.4.2

Fixed

Fixed
  • Time-stretch now works in playback and stem export. A pad stretched to the project tempo, in BPM or BAR mode, plays and exports at that speed with its pitch unchanged. Before, you got the sample at its original speed
  • Loops play continuously across bars and scene changes instead of restarting at every bar
  • Loops-only factory projects now show up and play in the Project Viewer
  • Loop waveforms in the timeline now line up with what you hear
  • Exporting the full mix no longer clips when several groups peak at once
  • Ableton export now includes loops that were latched in live mode
  • Samples trimmed from the front no longer play past their trim end when triggered from a pattern
  • If the app's backend crashes, the next launch now reports it, so rare crashes get seen and fixed instead of vanishing

Improved

Improved
  • The conversion dialog puts its actions above the warnings, so you can reach them without scrolling

1.4.1

Fixed

Fixed
  • macOS: the app could crash the moment it opened if other software on the system interfered with WebKit, the component that renders the interface. It now rides that out instead of crashing
  • Crashes in the app's backend are now recorded in the session log, so support reports are easier to diagnose

1.4.0

New

New
  • Chop a sample into equal slices. Cut it into 4, 8, 16 or any number of even slices in the Sample Editor, snapped to zero crossings. Made for breaks and loops
  • Convert projects between devices. Move a project between EP-133, EP-40 and EP-1320 and the app remaps it for the target device
  • Batch process samples straight from your device. Multi-select in File Manager, send to the Batch Processor and write the results back to the device
  • 3-band EQ in the Sample Editor processing toolbar
  • Guided tours. Every tool now has a short walkthrough you can take or skip, plus a getting-started checklist so new users know where to begin
  • Select mode. Tap Select in list views to pick several items at once for tagging, exporting or deleting
  • Double-tap the waveform to zoom in on a section (double-click on desktop)
  • Sample settings now use hardware-style knobs and faders
  • Reorder samples by dragging rows in the Sample Editor list, or drop a row on a pad to assign it

Improved

Improved
  • The Pro trial now shows how many days are left in the header and warns you before it ends
  • Full-screen splash on phones and tablets, with the device artwork front and centre

Fixed

Fixed
  • Some sample names made device uploads fail with an invalid length error. Names are now kept within what the device accepts, and you can rename samples directly in the Batch Processor table
  • Batch Processor sessions restore properly after a restart
  • Writing a processed sample back to the device no longer overwrites looped or multisample sounds, which the device cannot rebuild from a plain sample
  • Fixed a licensing issue that could affect the Pro trial
  • The phone header no longer wraps. The trial pill stays beside the wordmark and the connection state is a compact icon
  • iOS: the launch screen icon showed white corners in dark mode. It no longer does

1.3.1

New

New
  • Android: EP-PatchStudio now checks for updates from inside the app. You get a notification when a new version is ready, and you can turn automatic checks on or off, or check manually, from Preferences

Fixed

Fixed
  • iOS: the header could sit under the status bar for a moment when the app first opened. It now stays clear of it from the start
  • iOS: the upgrade nudges could hide behind the bottom tab bar. They now sit above it

1.3.0

New

New
  • Device Info is now a full dashboard. See your connected device with its own artwork, check storage at a glance and manage everything from one screen
  • In-app backups. Back up your device without leaving the app. Backups save automatically, you can tag and pin the ones worth keeping and import projects straight from a backup into your Project Library
  • Project Sets. Save all nine of your device's project slots together as a named set, then load the whole set back in one go. Before it overwrites anything the app snapshots what is on your device first, so nothing is lost
  • Sample Packs is now its own tool. Export a pack as a zip to share, import a pack from a zip and tag your packs. Imports now accept AIFF and MP3 as well

Improved

Improved
  • Project Sets and Sample Packs are now top-level tools, with the navigation grouped so related tools sit together

Fixed

Fixed
  • Key detection always reported C no matter the sample. It now detects the actual key
  • Optimise loop points did nothing on some samples. It now works as intended
  • Removed FLAC from the audio file pickers. EP devices cannot play FLAC, so offering it only led to failed imports
  • Tidied the British spelling of Licence in the interface
  • iOS: fixed a crash when opening file pickers, plus several layout fixes for phone and tablet

1.2.0

New

New
  • Open Source Licenses: a new listing in About > Legal that credits the open-source projects EP-PatchStudio is built with

Improved

Improved
  • You can now use your licence on up to 5 devices, raised from 3

Fixed

Fixed
  • The app no longer keeps telling you to update your firmware when your device is already on the latest version
  • The Mono, Oxide, Parchment and Tape Hiss themes now show in their proper fonts. They were quietly falling back to a system font before

1.1.0

New

New
  • EP-PatchStudio is now on Android. Import audio, edit and trim samples, build kits and multisamples and send them straight to your EP over USB. Download the APK from the website

1.0.2

Fixed

Fixed
  • iOS: you can now pick .pak and .ppak files when importing to the Project Library. The file picker was greying them out, so there was no way to select your backup

Improved

Improved
  • Project Viewer: the timeline lists pad lanes in the same order as the pads on your device, so the labels read in sequence instead of jumping around

1.0.1

Fixed

Fixed
  • Linux: the app now finds your connected EP device again. It was mistaking the desktop window for Android and choosing the wrong MIDI connection, so no device showed up
  • Linux: fixed a blank window on newer systems such as Bazzite and SteamOS, caused by bundled Wayland libraries clashing with the ones already on your machine
  • Linux: the AppImage build now plays audio
  • Restored the device-backup confirmation on the first-run welcome screen, so you are reminded to back up with the official EP Sample Tool before you start

0.36.3

Improved

Improved
  • The file manager, sample editor and batch processor tables now adapt to phone and tablet screens, hiding less-important columns and moving row actions into a menu so nothing runs off the edge
  • The file manager toolbar is tidier on phone, with secondary actions grouped into Options and Actions menus instead of stacking up
  • Buttons and tap targets now meet the minimum comfortable size on phones and tablets

Fixed

Fixed
  • App content no longer sits under the status bar, notch or home indicator on iPad
  • Fixed a double scrollbar on iPhone that made a page need a second swipe to scroll to the end
  • Button labels and type badges no longer get cut off on narrow screens
  • The iPhone app now stays in portrait, so the layout no longer breaks in landscape

0.36.2

Improved

Improved
  • Downloading a sample that isn't already cached now shows a progress indicator
  • The mobile app shows a BETA badge with the version on its splash screen

Fixed

Fixed
  • Samples now play through the speaker on iPhone and iPad, including when the silent switch is on
  • Library Insights works again on the mobile app
  • App content no longer sits under the status bar and notch on iPhone and iPad
  • The file manager's Type column is now wide enough to read on mobile
  • The physical-keyboard play hint no longer appears on iPhone and iPad, where it doesn't apply
  • The mobile interface no longer zooms or pans by accident

0.36.1

New

New
  • You can now choose C3 or C4 note naming in Settings under Preferences > Appearance. C3 names middle C (MIDI 60) the way Ableton Live and FL Studio do, C4 is scientific pitch. The choice applies everywhere note names appear, and was previously only reachable from the multisample keyboard

Fixed

Fixed
  • The Auto-Sampler note range now uses the same note naming as the rest of the app. With the default C4 naming the range and the resulting root notes read an octave higher than the range you picked, so choosing D#2 to D#3 showed root notes of D#3 to D#4. The samples were always recorded and mapped to the right notes, only the labels were off

0.36.0

New

New
  • Stem export can now render each pad to its own track and split the export by scene, so you can drop individual hits or whole sections straight into a DAW. A new Source sample-rate option keeps each sample at its own rate instead of upsampling the low-rate EP samples
  • Pads set to loop on the EP-40 now show and play as continuous loop regions in the Timeline, instead of showing nothing useful
  • The Auto-Sampler Setup Guide now opens with a signal-routing diagram that shows how MIDI and audio flow through your setup, so the loopback step is easier to get right

Improved

Improved
  • Views fade in gently as you move between them. The animation respects your system reduced-motion setting

Fixed

Fixed
  • EP-40 projects from the current firmware (1.0.5) now load correctly in Timeline view and stem export. Their pattern data was being misread, which left the timeline empty or stretched the samples into a low-pitched rumble with wildly wrong bar counts. Pad View was never affected
  • Projects that are just loose pattern variants, jammed without building a song, now show up in the Timeline, stem export and DAW exports instead of appearing empty
  • Notes played below their root pitch (or with Time set below its centre) no longer cut off early during timeline playback and stem export

0.35.2

Fixed

Fixed
  • EP devices connect again on desktop. A change from the mobile work had routed the desktop app onto the wrong MIDI backend, so your EP-133, EP-40 or EP-1320 could show as disconnected even while other apps still saw it. Desktop is back on its own MIDI connection
  • Windows drivers that expose a device as separate "MIDI IN" and "MIDI OUT" ports now pair correctly, so the device connects instead of being dropped
  • The header no longer reads "Disconnected" for a MIDI device that is actually connected, and the connected-device count is now accurate
  • EP-133 is recognised even when its driver reports it only as "K.O. II", and EP-1320 when reported only as "Medieval"
  • Auto-Sampler now records audio from VoiceMeeter virtual outputs on Windows. They previously opened without error but captured only silence
  • Shift-click and Ctrl/Cmd-click multi-select works again in the file manager
  • The sample rate shown right after a batch upload is now correct, instead of briefly showing the previous sample's value

Improved

Improved
  • Project libraries and sample packs now keep their audio on disk rather than inside the app database, so large collections stay responsive. Existing data moves across automatically the first time you open this version

0.35.1

Fixed

Fixed
  • The macOS app no longer crashes on launch. A MIDI setup conflict introduced in 0.35.0 aborted the app on startup on macOS only. Windows and Linux were not affected

0.35.0

New

New
  • Multisample note zones — a zone lane in the multisample editor shows the note range each sample covers. Ranges split automatically across your samples and you can drag the boundaries or set per-sample high and low limits by hand. Two samples sharing a root note raise a warning, and one click reverts to automatic splits

Improved

Improved
  • The sample table's "Note" column is now labelled "Root Note", so it's clear it sets each sample's root rather than a fixed pitch
  • The keyboard no longer scrolls itself when you hover a sample row, so it stays put while you work in the zone lane

Fixed

Fixed
  • EP-40 multisamples now play click-free. This fixes the region-boundary clicks and the noise-gate tail crackle when pads release
  • Auto-Sampler can now reach the microphone on Windows. A stored WebView2 permission block was rejecting recording even after a reinstall
  • Importing a multisample from a device slot no longer reads past the region boundary
  • Looped samples trimmed at the start now export their loop points in the right place, instead of shifted later by the trim length

0.34.1

Improved

Improved
  • Windows installer is now digitally signed, so Microsoft Defender and SmartScreen no longer warn during installation

0.34.0

New

New
  • Library Insights — new Insights tab with stats from your whole project library: activity heatmap, tempo histogram, sound usage, project structure and a producer personality card. Includes an annual Wrapped recap with shareable PNG cards. All data stays on your device. Pro feature
  • Ableton Live export — export any project as a Live 12 set (.als). Tracks come across with names, colours, MIDI clips, samples, trim points and group mixer levels and pan. Live 12 only
  • Sample Packs tab in the File Manager — bundle samples into named packs, import whole folders (handles 8/24/32-bit, float and surround WAVs) and save selected slots or a project's sounds as a new pack
  • Optimise samples in the File Manager — convert stereo samples to mono and downsample to a target sample rate to free up device storage

Improved

Improved
  • Stem export fidelity — correct loudness, release tails at scene boundaries and reduced aliasing. Renders at 88.2 kHz only when a project pitches samples up, so most exports are faster
  • Auto-Sampler microphone permission errors now explain how to fix them on your platform, and the setup guide notes the macOS 2-channel limit for multi-input interfaces
  • MIDI device detection — devices plugged in after the app starts are now picked up, and devices with mismatched input/output manufacturer fields connect reliably

Fixed

Fixed
  • Auto-Sampler no longer records silent samples on macOS and the device dropdown no longer collapses to one entry
  • Scene audio is scheduled immediately during timeline playback so scene changes no longer jitter
  • Batch Processor TNGE export now applies the 2x speed setting
  • Stem export now applies the sample's stored volume
  • Editor defaults no longer override the play mode of every pad in a multisample
  • Timeline preview applies the device's default delay effect when a project has no effect settings
  • Project backups round-trip byte-faithfully through the editor so unmodelled data survives a save
  • Enter License Key button now lands on the licence page with the entry form open

0.33.0

New

New
  • Batch Processor is now available to everyone. The Beta badge stays for one more release as a soft launch signal
  • Combined Sample Editor in the Batch Processor with full waveform editing, markers, zoom, loop region and per-file settings overrides in a single tabbed modal
  • Trim to Sample Start/End Markers — new Crop button in the Sample Editor toolbar that destructively trims audio outside the in/out markers. Helpful for fitting longer material under the 20-second TNGE limit and for cleaning up samples before normalise, fade or auto-chop
  • The Batch Processor is the headline change in this release. If you use it please share feedback through GitHub issues or the support email so I can polish it before dropping the Beta badge next release

Improved

Improved
  • Auto-chop now works in Drum Kit mode. Slices land on the active scale's kit pad notes instead of a chromatic sequence
  • Move and swap modal copy now reads "affected projects will play the moved/swapped samples" instead of the misleading "project references will be updated automatically"
  • Batch move modal now shows the project warning that was previously missing
  • Alert titles in move and swap modals use Title Case

Fixed

Fixed
  • Drum kit TNGE files reopen in the Drum Kit layout instead of the melodic keyboard
  • Drum kit pads no longer silent when loaded files lack a MIDI note in the filename
  • Multisample export no longer produces wrong zones when switching from Drum Kit to Melodic mode
  • Windows microphone permission error in the Auto-Sampler now shows clear guidance instead of a generic audio input error
  • Stem export pitch modulation now matches device playback when automation starts mid-pattern
  • Timeline and sample blocks no longer render at the wrong width on projects with mixed event types
  • File Manager swap now plays the correct content after swapping (was playing unrelated samples)

0.32.5

Improved

Improved
  • Kit mode now defaults to oneshot playmode with full release, matching stock percussive multisamples

Fixed

Fixed
  • TNGE multisample import no longer names regions one octave lower than the Note column

0.32.4

New

New
  • Save Current as Default and Reset to Factory Defaults options in the editor settings menu

Improved

Improved

  • Play mode selector restored for multisample and kit modes

Fixed

Fixed
  • Kit drum exports no longer assign samples to the wrong pads on the EP-40
  • Changing the kit root note pitch class no longer jumps to the wrong octave
  • Kit regions no longer include loop data (prevents unwanted looping on device)

0.32.3

Improved

Improved
  • Drum kit mode is now part of the Multisample Editor

Fixed

Fixed
  • Multisample play mode is now locked to key mode (was incorrectly reverting on import)
  • TNGE import no longer fails when the sample.mode field is missing
  • Loop data is only set when both loop start and loop end markers are present
  • Navigating to Settings > License tab now works when clicking Enter License Key
  • Export Diagnostic Logs no longer opens the email client — the ZIP is saved separately and the support email link opens the pre-filled mailto instead

0.32.2

Improved

Improved
  • Project Viewer timeline now has a floating horizontal scrollbar that stays visible at the bottom of the viewport

Fixed

Fixed
  • Fixed an error when importing single-mode TNGE files without regions into the Sample Editor
  • Further fix for the invisible window issue on macOS introduced in v0.32.1

0.32.1

Fixed

Fixed
  • Fixed a bug where the app window could become permanently invisible on macOS. If the app was quit while hidden (Cmd+H then Cmd+Q, or before the window was shown on first launch), it would never appear again on subsequent launches.
