TD3 STUDIO
Never before has programming the TD-3 been this easy. Drop a MIDI file on the instrument, slide the window over the bars you want, and the sixteen steps are cut for you — notes, octaves, accents, slides and ties. Hear it through the built-in 303 simulator, tweak it on the plate, and WRITE it straight into the TD-3 over USB.

FROM MIDI TO TD-3
Drop a MIDI file
Any Standard MIDI file. The timeline above the plate shows the whole clip.
Slide the window
Drag the amber window over the sixteen steps you want, step by bar, or Ctrl + scroll to zoom in and land it to the step.
Tweak, hear, record
Turn the knobs, listen through the 303 simulator, fix a step by hand or step-record from the keyboard.
WRITE to the TD-3
Pick group, pattern and bank and press WRITE. The pattern is on the device. BACKUP fetches all 64.
THE PLATE IS THE TD-3
MIDI → pattern
Chords resolved the way you choose, accents from velocity, the root note follows the notes in the window, triplet time when you need it.
Sixteen steps, hands on
Note, octave, accent (amber) and slide (red) on every cell. Click to select, scroll to move a semitone, modifier-click for accent, slide, tie and rest. Undo included.
Play it in
A three-octave keyboard with 303-style step recording: press REC and every key, TIE or REST fills the next step. Or plug in a MIDI keyboard — velocity gives accents, legato gives slides.
Hear it
Output to the TD-3 over USB, any MIDI output, or the built-in simulator through your speakers: saw or square, resonant filter, envelope, accent and slides.
A library
Your own .syx, SynthTribe .seq / .sqs and .mid files with thumbnails and audition, 107 bundled Acid-Tabs lines, and a search across free MIDI archives.
Help built in
A short tour on first start, a help panel per part of the instrument, and every control explains itself when you hover. Updates install themselves.

FAQ
Does it work with the TD-3-MO?
Yes. WRITE, BACKUP and playing through the device work on the TD-3 and the TD-3-MO over USB. Tone lives on the device; the knobs on the plate drive the simulator.
Windows says "Windows protected your PC" / macOS says "unidentified developer".
The installers are not code-signed yet, so both systems warn once. Windows: More info › Run anyway. Mac: right-click › Open. Step by step, with pictures: installation guide.
How do updates work?
TD3 Studio checks once a day and, when you agree, installs the new version itself (on a Mac the new disk image opens in Finder). No extra cost, ever.
Can I switch from Windows to Mac later?
The platform you pick at checkout is final — no swap, no refund. A licence for the other platform costs €15 with the same e-mail address, or take both at once for €35.
Lost the download link?
The link in your e-mail is valid for 30 days; after that the app updates itself. Lost the mail? Use Report an issue… in the app or write to td3studio@50hz-services.nl.
Something is wrong — where do I report it?
In the app: setup key › Report an issue… sends a short report with your version and setup attached, no account needed. Release notes and docs live on GitHub.
