Syxloom: MIDI SysEx

Syxloom is an offline MIDI System Exclusive workbench for synthesists, repair benches, studios, and anyone keeping older hardware alive. Capture a dump, see exactly what arrived, split it into the patches that matter, and send back precisely what you choose — with the byte-level detail a service manual assumes you have. THE BENCH - Send sets: ordered selections from your library sent as one paced transfer - Per-set message gap, with a wire-time estimate before you commit - Byte-level diff of any two messages: changed regions by offset, aligned hex - Sets survive renames — they reference entries, not copies CAPTURE - Finds every CoreMIDI source: USB interfaces, Bluetooth MIDI, virtual ports, network sessions, and other apps on this device - Reassembles dumps that arrive across many MIDI packets - Keeps interleaved clock and active-sensing bytes out of the payload - Flushes stalled transfers so a failing cable is visible, not silent - Live receive meter: bytes per second, as it happens DEVICES - Census: broadcast the Universal Identity Request, and every reply becomes a card naming manufacturer, family, member code, and firmware version - Request builder: Roland RQ1 with the checksum computed over address and size; a raw hex composer that validates 7-bit data before sending - Pacing profiles: per-device transmit gaps, set once and remembered INSPECT - Manufacturer identification from the full published one- and three-byte ID registry, with regional grouping - Universal message decoding: identity, GM state, master volume, and more - Roland and Yamaha checksum verification, with the failing byte named - Structural checks: framing, 7-bit violations, truncation, declared lengths LIBRARY - Name, tag, and annotate every message; instant search across all of it - Import .syx files, paste hex straight from a service manual, export and share anything Everything is stored on this device. No account, no ads, no analytics, no network calls. Your patches are yours.
