New in v0.2.9

• Added Keep source track volumes. When enabled, generated replacement tracks keep closer to the original MIDI role/track loudness balance, even if instruments are changed.
• The source MIDI analysis now reports average velocity and estimated source volume per track.
• Render analysis TXT writes whether source-volume preservation was enabled.
• CLI supports --preserve-source-volumes.
• Includes the feedback learning, PyInstaller compile script, Source MIDI button placement, modular changelog folder, neutral bundled example MIDI, and standalone source comments from v0.2.8.

New in v0.2.8

• Added local listener feedback / preference learning.
• After rendering a result, use 👍 Like Last or 👎 Dislike Last to rate it.
• Future renders can gently bias settings toward liked results and away from disliked patterns.
• Feedback is stored locally in app_data/feedback/ratings.json.
• Added Reset Feedback to clear the learning profile.
• Moved Play Source MIDI into the Source / Output section, so the bottom action row stays focused on main workflow actions.
• Added compile_windows_pyinstaller.bat to build a Windows EXE folder with PyInstaller.
• Improved PyInstaller runtime paths so bundled styles, themes and language files load correctly, while feedback remains writable next to the EXE.
• Kept changelogs in docs/changelog/ instead of the project root.

New in v0.2.7

• Reworked the former Repeated note amount control into Accompaniment relaxation.
• Moving the slider right now reduces fast repeated accompaniment attacks and creates more breathing room.
• High relaxation values add long harmony-safe pad/string relief layers instead of endless pluck/tick repetitions.
• Dense source-derived arp, glass support and tonal tick tracks are now thinned by the relaxation value.
• The analysis TXT now writes Accompaniment relaxation so generated files are easier to diagnose.

New in v0.2.6

• Expanded style preset library with additional house, grime, hardcore, DnB, rave, rock and experimental styles.
• Presets are alphabetically sorted and remain editable through app/styles/style_presets.json.

New in v0.2.5

• Added more style presets: Amapiano, Cumbia, Ragga, Electro Swing, UK Bass, UKG, Two Step, Acid Jazz, Rare Groove, Balearic and more.
• Added Play Source MIDI for direct comparison with the selected input file.
• Split output playback into Play MIDI Output and Play WAV/MP3 Output.
• Expanded WAV sample rates: 22050, 32000, 44100, 48000, 96000, 128000 Hz.
• GUI uses a vertical scroll area, so controls should not be cut off on smaller screens.
• Themes are external .qss files in app/themes/.
• Language files are external JSON files in app/lang/.

Core controls

• Style selects the target arrangement/style preset.
• Random Style from seed chooses a style deterministically from the seed.
• Transformation Intensity controls how strongly the song is rearranged.
• BPM controls tempo independently from transformation intensity.
• Accompaniment relaxation controls whether fast accompaniment keeps pulsing or is thinned into breathing room with pads/strings.
• Harmony lock snaps copied lead/arp/pad material to compatible scale/chord tones.
• Use style lead/melody instruments optionally replaces lead/hook/pluck/echo instruments with style-appropriate instruments.
• Keep source track volumes keeps the generated mix closer to the original MIDI balance.
• New random seed each render is enabled by default; disable it to reproduce a specific seed.
• Listener Feedback / Learning stores local thumbs-up/down ratings and gently biases future renders.

Build EXE on Windows

Run:

compile_windows_pyinstaller.bat

The script builds an onedir EXE package at:

dist\SynthwaveMidiReimaginerGUI\SynthwaveMidiReimaginerGUI.exe

The onedir layout is intentional: it keeps modular styles, themes and languages bundled safely and keeps the feedback profile writable under app_data/feedback/ratings.json next to the EXE.

Modular files

• Styles: app/styles/style_presets.json
• CSV overview: app/styles/electronic_styles.csv
• UI themes: app/themes/*.qss
• UI language files: app/lang/*.json
• Feedback profile: app_data/feedback/ratings.json
• Changelogs: docs/changelog/

Running from source

Run install_windows.bat, then run_windows.bat.

For offline reuse after a first online setup, keep the .venv folder or prepare a wheelhouse with prepare_wheelhouse_online.bat.

Notes

The Tool make use of the default mediaplayer (suggestion: VideoLAN / VLC). In some cases and using some specific styles the output might be a bit better using Midi-Playback instead of Wav/Mp3 playback (for me for ex. using "choral" preset with a good wavetable setup in VLC or a midi compatible backend).
