Syncopation Pro

Music, Audio, Books. No Cloud.

Only for Mac

$19.99

Mac

Your whole library in one window: album art, playlists, an equalizer, your music library put right, and a switch that turns the internet off. What else do you need¿! Somewhere along the way, "your" music started renting itself back to you. Your books phone home. Your files live on a server farm with better job security than you. Syncopation Pro is for the people who opted out of cloud. It takes the files on your Mac — music, audiobooks, podcasts, ePUB and PDF books, anything at all — and puts them on devices you actually own: SD cards, MP3 players, folders, e-readers, and yes, genuine click-wheel iPods. The ones with no ads, no accounts, no notifications, and a battery that lasts a week because it isn't doing anything behind your back. FOUR MODES. ZERO CLOUD. • Music — every audio format you've hoarded (MP3, FLAC, ALAC, AAC, WAV, the works) to an SD card, an MP3 player (Rockbox included), a folder, or an iPod. Folder structure intact. • Audio — audiobooks and podcasts, filed into the iPod's own Audiobooks and Podcasts menus. They resume where you stopped and stay out of shuffle. DRM-free files only; Audible knows what it did too. • ePUB/PDF — your books, on your reader, without a storefront in between • All Files — everything. No filtering. You're an adult. THE iPOD PART (THIS IS THE GOOD PART) • Knows what's on the cable — classic, video, nano, mini, photo or shuffle, and how much room it has — including your Franken-iPod with the terabyte flash mod. We see you. We respect you. • Writes the iPod's own database natively — including the checksummed format newer classics demand — so tracks play the moment you eject • The shuffle talks. Track names and its own status messages, recorded on your Mac in a voice you pick. The whole library goes on, or one playlist becomes its list. • FLAC and WAV convert to Apple Lossless automatically, at 16-bit, which is what the hardware actually plays. Hi-res files get downsampled properly instead of stuttering. • Album artwork rendered into the device's native formats. Cover Flow like it's 2007. • Reclaims wasted space — finds the audio files other software abandoned on your iPod and clears them out. 33 GB came back on one 160 GB classic — That isn't tidying, that's a fifth of the iPod. THE LIBRARY, IN ONE WINDOW • Biblio — your collection as a shelf and as a wall of covers. An album slides out to its tracks. Play it. Build and reorder playlists, and send one playlist or the whole library to the iPod or the card. Drop music in and it files itself. • Cair Engine — the mess, sorted. Cair identifies each track and files it into its real Artist / Album folder with the right name, tags and cover — the sure ones on their own, the rest with a single confirm. Point it at a shoebox of "Unknown Album" folders and get a library back. Your file formats are fully preserved. Video files are never touched. • Auditoré (ow-dee-tor-AY) — a five-band equalizer and gain on playback, live while a track plays, remembered between launches. • A toggle in Settings that actually stops Syncopation from connecting to the internet — What else do you need¿! BUILT BY SOMEONE WHO ACTUALLY SYNCS • Interrupted syncs resume. Cable yanked at track 3,000 of 4,000? Everything already copied is playable. Plug back in and carry on. • Conversion runs ahead of the copy, and the Mac holds off sleep until the last track lands. Then it lets go. • Synco never duplicates a track it's already seen — even ones some other app put there. • Syncing only adds unless you explicitly say otherwise, and every database write keeps a backup on the device. Paranoia, professionally applied. • Rockbox players sync as MP3 players. Music files are managed as expected. Light, dark, or whatever the system's doing. A chime when it's done — your alert sound, your volume. Works with iPod classic, video, nano (1st–4th gen), mini, photo, and shuffle (4th gen) in disk mode (audiobook and podcast filing needs 2007-or-later iPod firmware). Not supported: iPod nano (5th gen and later), iPod shuffle (1st–3rd gen), iPod touch, iPhone. The shuffle has been forgiven.

The shuffle has been forgiven. • iPod shuffle, 4th generation. It has no screen, so it talks: track names and its own status messages, recorded on your Mac in a voice you pick in Settings. The whole library goes on, or one playlist becomes its list. • Rockbox players sync as MP3 players. Music files are managed as expected. • One converter for every iPod. FLAC, WAV and AIFF become Apple Lossless through the same pipeline the shuffle insisted on. • Cair Engine hears more of the hard ones: it listens further into a song, where the music is, and asks twice before giving up. • Settings, sorted by what you're doing: General, Biblio, Cair. • Getting Started, under Help. The cliff notes, not the manual. Repairs in this update: • The library index reads fast on any Mac, Intel included. • Covers finish what they start. A match you confirm after the run gets its cover too, and the covers bar closes when the last one lands. • Match no longer asks about removals on every sync; you said yes once. • Erase leaves a player's hidden files alone. • An empty destination says so, with a straight face.
