Syxloom

A private CoreMIDI librarian for capturing, validating, cataloging, and restoring SysEx files from iPhone or iPad.

Focused field tools

Frame Anatomy

A complete System Exclusive message begins with F0 and ends with F7; preserve both boundary bytes.

Manufacturer IDs

Display one-byte and extended three-byte manufacturer identifiers without guessing the device model.

Seven-Bit Payload

System Exclusive data bytes normally remain below 80 hex unless a device protocol explicitly frames status bytes.

Capture Gate

Accumulate packets until F7 so a long message split by CoreMIDI is stored as one record.

Chunk Timing

Older devices may require smaller sends and quiet time; expose timing instead of hiding it.

Checksums

Treat checksum formulas as protocol-specific and label every helper with its exact convention.

Syxloom transmits only MIDI data the user selects. Confirm backups, device compatibility, routing, timing, and manufacturer procedures before sending data to hardware.
