Syxloom: MIDI SysEx

Keep your MIDI SysEx work organized, see what is inside it, and review exactly what you are about to send.

NEW IN 5.1 — MORE FM PATCH NAMES, FAVOURITES AND SETLISTS
The inspector now lists patch names in Yamaha TX81Z, DX21, DX27 and DX100 voices and banks, TX81Z performances, Yamaha reface DX voices and Korg volca fm2 programs alongside the DX7, Korg logue, Sequential, Circuit and DeepMind 12 formats from 5.0. Recognition is based on published MIDI specifications; community-documented layouts are labelled. DX7 voices and banks are marked as compatible with the Korg volca fm and volca fm2, which receive DX7 data.

Mark favourites, filter by tag, and search with several words across names, tags, notes, recognised models and patch names. Give entries in a send set their own destinations to build a setlist that sends to several instruments in one reviewed transfer. Shortcuts can open a library entry, import a SysEx file or prepare a send set; nothing is sent until you confirm in the app.

PATCH TOOLS
Build a 32-voice DX7 bank from voices anywhere in your library, save a single voice or rename one into a new copy. Edit bytes as hex with live validation, repair a Roland, Yamaha or XG checksum into a new copy, import SysEx from Standard MIDI Files (.mid), and find identical files or the same sound saved under another name. Audition a destination with a test note, chord, program change or All Notes Off, and use patch-request presets with documented or clearly marked suggested pacing gaps.

CAPTURE AND INSPECT
Monitor chosen CoreMIDI sources, inspect complete and partial messages, and keep the reported source and termination details. Import .syx and .mid files, review framing and supported checksum layouts, and compare changed byte regions. Unknown device formats remain unverified.

A REVIEWED TRANSFER
Prepare a frozen plan with the destination, exact message order and effective pacing before confirming a send. Use remembered device pacing profiles, follow progress and cancel later messages. One transfer runs at a time. The app never silently replays an interrupted operation.

SNAPSHOT COMPARE
Save copies of selected messages before a session or repair, compare two snapshots and share a JSON change report. Comparison never sends MIDI.

KEEP A RECEIPT
Review the latest 200 local transfer receipts with message hashes, destination, pacing and completion, cancellation or failure. CoreMIDI completion records the operating system's result; it does not prove the instrument received or stored a patch.

A RECOVERABLE WORKSPACE
Name, tag and favourite messages, add notes and build ordered send sets and setlists. Export the complete workspace, inspect a backup before replacing current work, and preserve original bytes when recovering unreadable storage. Backups include exact SysEx bytes and metadata. They are unencrypted; the integrity checksum detects accidental corruption and does not authenticate the author.

EXPLORE WITHOUT AN INSTRUMENT
Nine labeled sample messages and a capture walkthrough introduce the workbench. An explicitly offline pipeline check exercises validation, review, pacing and capture through an internal transport. It sends no MIDI and does not test hardware compatibility.

CONNECTIONS YOU CHOOSE
Use compatible CoreMIDI interfaces or endpoints supplied by the system and other apps. Optional Bluetooth MIDI pairing is available. Real capture and transmission require a compatible connection and the instrument's documented settings. Syxloom performs foreground MIDI work.

No account, subscription, in-app purchase, advertising, tracking or developer-operated upload service. Your library, profiles and receipts stay local unless you choose a connection or sharing destination.

SysEx can change device settings and stored patches. Follow the exact model's MIDI implementation and backup procedure. Syxloom does not certify firmware updates or automatically restore hardware.

Syxloom 5.1 adds patch names for more FM instruments, favourites, tag filters, setlists that mix instruments, and Shortcuts.

More patch names: Yamaha TX81Z, DX21, DX27 and DX100 single voices and 32-voice banks, TX81Z performances, Yamaha reface DX voices, and Korg volca fm2 programs. The volca fm2 layout is community-documented and labelled as such in the app. DX7 voices and banks are shown as compatible with the Korg volca fm and volca fm2, which receive DX7 data. A 4-op bank and a DX7 bank are told apart by their format byte, never by length alone.

Fixed: reface DX dumps no longer show a false checksum or length warning.

A reface DX voice (header, blocks and footer) and a TX81Z voice with its additional data now stay together as one library entry, on import and when saved from Monitor. The inspector checks them message by message.

Library: mark favourites, filter by tag or favourites, and search with several words across names, tags, notes, recognised models and patch names.

Setlists: give entries in a send set their own destinations to send to several instruments in one reviewed transfer. A destination that is not connected blocks the review; nothing is sent to another port.

Requests: new presets for the 4-op family, reface DX, Prophet '08 and DeepMind 12. Notes for the original DX7 and Circuit are clearer, and suggested gaps are marked separately from documented ones.

Shortcuts: open a library entry, import a SysEx file, or prepare a send set. Nothing is sent until you confirm in the app.

Recognition is based on published MIDI specifications, and on community documentation where labelled. These additions were tested against generated data, not instruments. Syxloom does not confirm that an instrument received or stored a patch.
