A portable copy keeps its settings, projects and banks in a userdata folder beside the
executable, so it can live on a memory stick and leaves nothing behind. An installed copy
keeps them under your documents. Both are the same application, and the updater offers
whichever kind you already have.

On Debian 13, Ubuntu 25.04 and the systems built on them there are also
md-synth-daw_1.0.2_amd64.deb and md-synth-daw_1.0.2_arm64.deb, and the website's apt
repository, which keeps an installed copy up to date along with the rest of the system. The
commands are under Install with
apt in the README.

Checking a download

SHA256SUMS lists every file, and each file has a .sigstore bundle beside it,
SHA256SUMS included. The signature is what proves a download came from this repository: a
checksum on its own only proves the file matches whichever list you read it from.

What changed

The song model (1)

• Patch A preset file cannot name a part or a lane the model has no room for

Playback and export (1)

• Render A device above 163840 Hz no longer hangs the priming

File formats (6)

• Audio A wave chunk size near 2 GB cannot wrap past the end check
• Midi A division of nought and a runaway tick count read safely
• Project A fresh build writes the shipped banks again
• Project A damaged project cannot read outside itself or past what the model holds
• Vgm A sample block or a tag offset near 2 GB cannot hang or wrap the read
• Xgm A music length or a tag offset near 2 GB no longer wraps negative

The interface (1)

• Paint A font baked too tall for the atlas comes back instead of spinning

The application (3)

• Files A copy in a folder named outside ASCII is updated on Windows
• Files The Linux updater waits for the application to close and asks first
• Files An update that needs an administrator asks before the application closes

Window, audio and system (8)

• Crash A report is written under a settings folder named outside ASCII
• Draw A read back past the target copies only what SDL hands back
• System A save swaps the whole file in rather than deleting the old one first
• System The one instance socket in /tmp carries the account's id
• System Commands the application runs get no window of their own
• Text A font name with a broken surrogate pair reads without a bad character
• Text A face in a folder named outside ASCII loads on Windows
• Window Typed text, a dropped path and a paste never end mid character

Building and packaging (8)

• The release notes name the Debian packages and point to the apt commands
• The installer's identity is named in mdd.xml rather than hashed from the publisher
• Hxcpp is held at v4.3.157, and a build refuses a collector known to fault
• A Linux build is also a Debian package, which apt keeps up to date
• A packaged program keeps its executable bit
• The Go faces come from GitHub, and setup and package stop without them
• The macOS bundle and its document types are com.victorLR.mdd
• The installer's terms list every official download page

The repository (2)

• Bump version 1.0.2
• The licence and its notices name Victor L. Roxbåge (MeguminBOT)

Documentation and checks (6)

Documentation (3)

• The install guide gives the apt commands and the Debian package on its own
• The install section names every official download page
• The transport slides and the time signature text show one shared field

Checks (3)

• The mangle check runs any set of its sections on their own with --only
• The mangle check builds the files random corruption never makes
• The font download check works where there is no drive R

The application (9)

• Menus The pitch bend range is a MIDI preference, and a keyboard can send its own
• Menus R turns record on and off, as the transport bar's tooltip already said
• Menus A MIDI keyboard's pedal, pitch wheel and held keys shape what the channel plays
• Session Writing automation as clips on the playlist is not offered for now
• Session A MIDI keyboard that is unplugged reconnects when it comes back
• Session A recorded take and a run of knob turns are each one step to undo
• Session A MIDI keyboard records notes while record is on, at the nearest grid line

• Session A song ending, a session change and the running clock each ask for a frame

Window, audio and system (2)

• Draw Textures kept for a widget, drawn back unscaled, and the vertices counted

• Wrap lanes array in build target conditions
• Clearing a language in the installer deletes the font it fetched too
• A package takes what it names, and the portable one leaves out fetched fonts

A portable copy keeps its settings, projects and banks in a userdata folder beside the
executable, so it can live on a memory stick and leaves nothing behind. An installed copy
keeps them under your documents. Both are the same application, and the updater offers
whichever kind you already have.

SHA256SUMS included. The signature is what proves a download came from this repository: a
checksum on its own only proves the file matches whichever list you read it from.

What changed

The song model (2)

• A clip can be given a pattern nothing else is looking at

• Stream An export reserves a guess and grows into it

File formats (6)

• Audio A format chunk is read only where it is long enough to hold one
• Midi Events are read inside the track, and a length cannot run backwards
• Project A document is not trusted for an index, a length or a depth
• Vgm A log is read inside its own length, and a gzip cannot unpack without end
• Xgm A piece past thirteen minutes is written rather than exhausting memory
• Xgm A tag block that starts before the file is refused

Editors and panels (4)

• Overlay The system monitor row shows the choice it holds
• Overlay A question can be asked and one of three answers taken
• Overlay The update notice is seen rather than leaving a dark window nobody can use

The interface (6)

• Locale A language whose font is missing can still be picked
• Paint A filled polygon gets the same soft edge a rounded corner already had
• Widget The pointer says a seam can be dragged
• Widget The splitter nothing built is gone

The application (7)

• Files Work in no file yet is asked about before anything replaces it
• Files Every look and every download writes down what it did
• Files The releases page is asked once a run rather than whenever a setting is applied
• Files An update with nothing to download is not offered
• Files A download is checked against the published hashes before it is unpacked
• Session Discord presence is described as starting at full, which it does
• Session The status bar says as much as it is asked to, and the file menu remembers

Window, audio and system (5)

• Crash A stack overflow is reported everywhere, and a fault reaches the window
• System A value two threads share survives the collector
• System The graphics memory this process holds is measured
• System A portable marker only counts where the settings can actually be written

Building and packaging (7)

• The installer asks for its terms to be accepted first
• The installer lets the three CJK fonts be left out

Documentation and checks (10)

Documentation (7)

• The video libraries are credited, and the badges go into rows
• The readme names a minimum release for the three distributions most people run
• A feature not on the page is absent rather than presumed absent
• The detail behind the requirements moves to a page of its own
• The graphics and storage figures carry room rather than the measured floor
• The system requirements say what was measured rather than what was assumed
• The warnings a build prints, and which of them were measured before being left alone

Checks (3)

• The two states a real repository puts the updater in are driven end to end
• The video encoder is measured against the processors rather than taken on trust
• A program that measures what the heavy paths cost on a piece built to be worse
