* Progress docs to the craftrules standard; full re-measure against Pro Tools 2026.4.1 Stage: alpha. Menu breadth 482/512 (94.1%, measured), feature breadth ~70%, ready for real work ~40%; ~350-570 agent-hours to beta, ~950-1,450 to full parity, calibrated on this repo's PR history. - ROADMAP.md rewritten: stage banner, two numbers, dimension/feature/language tables - docs/target-app-parity.md: authoritative assessment (area table moved from ROADMAP) - docs/gaps.md: 22 ranked gaps with evidence and estimates - docs/roadmap.md: milestones, current focus, beta plan - docs/ui-, file-format-, hardware-, plugin-, localization-parity.md: new checklists - docs/parity.md -> docs/parity-checklist.md (generated by cargo xtask parity) - architecture.md: video, vst3-host, au-host crates; device I/O limits Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Stage: pre-alpha under the core-workflow gate Add the alpha gate to docs/roadmap.md: interface recording at a chosen buffer size, MIDI recording, and session interchange with Pro Tools fail, so the stage moves from alpha to pre-alpha (~5 points and ~110-180 agent-hours to alpha). Mark the alpha blockers in docs/gaps.md; update ROADMAP.md, target-app-parity.md and README. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Add mainstream-practitioner and essentials-user readiness numbers Mainstream practitioner ~36% (weekly-area depth 50.6% x 0.90 interaction x 0.92 stability x 0.85 file exchange) and essentials user ~57% (core-feature depth 72.4% x 0.90 launch/stability x 0.90 discoverability x 0.97 files), with written weights, discounts and GitHub user evidence. Full ready-for-real-work checked against its written dimension weights (40.6%); unchanged at ~40%, stage unchanged. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Readiness by audience: hours to ~95% for full, mainstream and essentials Full ~40% / 950-1,450 h, mainstream ~36% / 380-600 h, essentials ~57% / 110-200 h, calibrated on this repo's PR history. The full number is already an additive weighted sum over the written dimension table; method unchanged.

SoundCraft roadmap: milestones and what's next
Last reviewed: 2026-10-10 · Last updated: 2026-10-10 · Change: minor (alpha gate added; stage re-normalized to pre-alpha) · Target: Avid Pro Tools Ultimate 2026.4.1
Forward-looking plan. Status and numbers: ../ROADMAP.md and
target-app-parity.md; the ranked work list: gaps.md.
Hours are Opus 5.5 agent-hours.
Current focus
- Merge or close the open bug-fix PRs (#123–#134, #146, #148, #75) and fix the rest of the correctness backlog (G-04). ≈ 15–25 h.
- Audio interface basics (G-01): device selection, buffer size, duplex stream, ASIO. ≈ 25–40 h.
- MIDI devices (G-02): input to armed tracks and instruments, output, thru, clock. ≈ 20–35 h.
- macOS plugin hosting (G-05): library-validation entitlement now (#153), then AU editors. ≈ 15–25 h.
- A PR CI that runs
cargo xtask cion Linux, macOS and Windows (G-14). ≈ 5–10 h.
Alpha gate
The core workflows a Pro Tools professional does every day, checked end to end on macOS (the
main platform). Any no keeps SoundCraft pre-alpha, and those rows are the alpha checklist
(craftrules standards/progress-docs.md, Stages).
| Workflow | Works end to end? | Evidence | Hours to pass |
|---|---|---|---|
| Record audio from a chosen interface at a chosen buffer size, monitor, punch, keep the takes | no | Default output and input devices only. Fixed 512-sample block. Separate input and output streams. setup.playback_engine params ignored by playback. Takes held in RAM until stop (PR #84). No input device choice (#42). |
35–55 |
| Record MIDI from a controller and play it back through an instrument | no | Playback of drawn and imported MIDI works. No MIDI device layer at all, so nothing can be recorded and instruments can't be played live (G-02). | 20–35 |
| Edit: select, trim, fade, comp playlists, Slip/Shuffle/Grid | yes (rough) | Every Edit menu command; property-tested with undo; open bugs #3, #5, #140 don't block the workflow | — |
| Mix with built-in and third-party plugins, sends, busses, automation | partial (passes on CLAP/AU) | 26 built-in processors; CLAP and AU host on the signed macOS build, but its missing entitlement blocks third-party VST3 (#153). No AU plugin windows yet; VST3 windows on macOS only | 1–2 (entitlement) |
| Bounce mix and stems; save and reopen the session | yes (rough) | WAV/BWF/AIFF/FLAC bounce, stems, .scraft save/reopen with plugin state; bugs #59, #103 in bus bounce and aux latency (PRs open) |
— |
| Exchange a session with Pro Tools or a picture editor | no | No .ptx, AAF or OMF import or export (#40, G-03) |
50–90 |
Result: pre-alpha. Three workflows fail. Passing them is ~110–180 h, about 70 % of it parallelizable (interfaces, MIDI and AAF are independent crates).
Milestones
Status: ✅ done · 🟡 in progress · ⬜ not started.
| # | Milestone | Status | Remaining (h) |
|---|---|---|---|
| M0–M4 | Workspace, gates, model, I/O, DSP, mix engine, command engine, Edit/Mix UI, playback, metering, plugins, bounce | ✅ | — |
| M5 | Editing depth (tools, modes, playlists, fades, comping, clip groups) | ✅ (bugs open, G-04) | in G-04 |
| M6 | Recording, punch, loop record, monitoring | 🟡 first cut; device choice and record-to-disk missing | 40–60 |
| M7 | MIDI and notation editing | 🟡 | 50–80 |
| M8 | CLI, control channel, MCP, agent acceptance test | ✅ | 3 |
| M9 | AudioSuite breadth ✅, Elastic Audio 🟡, Beat Detective 🟡 | 🟡 | 40–60 |
| M10 | Public releases on all platforms | ✅ v0.3.0 (2026-10-08) and v0.4.0 (2026-10-10) released for every platform | — |
| M11 | Third-party plugin hosting (CLAP, VST3, AU), video, surround | 🟡 mostly done | 40–60 |
| M12 | Hardware: audio interfaces, MIDI devices, sync, control surfaces | ⬜ | 110–180 |
| M13 | Interchange: AAF/OMF import/export, disk streaming, record to disk | ⬜ | 65–115 |
| M14 | Fidelity harness against Pro Tools (null tests, plugin responses) | ⬜ | 20–30 |
| M15 | Localization: catalog, fonts/RTL, the 8 Pro Tools languages first | ⬜ (PRs #141, #143 open) | 70–110 |
| M16 | Built-in plugin depth, sidechain, ARA | ⬜ | 110–170 |
| M17 | Immersive delivery (ADM BWF, object renderer, binaural) and video depth | ⬜ | 80–130 |
To beta (~350–570 h, about 60–70 % parallelizable)
Beta needs ~75 % ready for real work and no blocking gap in session interchange.
| Step | Gaps | Est. (h) |
|---|---|---|
| Correctness backlog and a PR CI | G-04, G-14 | 40–65 |
| Audio interfaces, MIDI devices, sync | G-01, G-02, G-11 | 60–100 |
| AAF/OMF interchange, disk streaming, record to disk | G-03, G-06 | 65–115 |
| Plugin hosting completeness on every OS, sidechain | G-05, G-13 | 35–60 |
| Fidelity harness and the fixes it finds | G-07 | 40–60 |
| Built-in plugin essentials (EQ/dynamics/reverb/delay depth, sampler) | G-08 (half) | 40–60 |
| UI feel pass: shortcuts, plugin windows, meters | G-19 (half) | 30–50 |
| Localization of the 8 Pro Tools languages (catalog, CJK fonts) | G-09 (part) | 40–60 |
Needs a human: hardware for G-01/G-02/G-10/G-11, native-speaker review, and owner decisions on
AAX, .ptx and Avid cloud features.
After beta (to full parity, a further ~600–900 h)
Control surfaces (G-10), immersive delivery (G-12), the rest of the built-in plugin catalogue (G-08), Elastic Audio depth (G-15), session templates and browser (G-16), video depth (G-17), speech-to-text (G-18), notation and instrument depth (G-20), compressed export (G-21), and the remaining languages.
There is no cargo xtask scorecard in this repo; the measured number is cargo xtask parity
(parity-checklist.md).
