The engine
Fixed 32-sample block, Plugin Latency Tolerance with per-slot blocks, AU + CLAP + VST3 in one chain, ten built-in plugins, rack macros.
Roadmap
coming soon
What's in testing today, what's on the bench, and what comes after.
What's built already
In testing Now
Capture
Multitrack audio and multiple cameras on one clock, Performance Record for the whole set, camera cuts recorded as editable timeline data.
The stage
DMX lighting on tracks (Art-Net and USB-DMX), looper station with FCB1010 support, phone remote with per-player IEM mixes, RTMPS streaming.
Writing
Tabs and notation on the MIDI engine, Guitar Pro export, vocal synthesis, the .jam song format and setlists.
Capture your gear
In-app Neural Amp Modeler training, impulse-response capture from a swept sine, drag-and-drop profiles onto racks.
Interop
Export to REAPER, Final Cut Pro (FCPXML) and OpenTimelineIO; import of every common audio container.
On the bench
In development
Code exists and is being tested. Not in testers' hands yet.
Session sharing between players
Peer-to-peer sessions on one shared transport and clock. TOAST already links machines across a local network; sharing whole sessions between bandmates comes first, then the same thing across the internet.
Freeze the rig
Distill a whole plugin chain into a captured NAM-A2 profile plus IR that plays back without the latency. Unfreeze to get the full processing chain back.
Portable core
The engine, clip store and session format extracted from the macOS shell so the same code runs on Linux and on phones.
After Launch
Next
In roughly this order.
Record direct to cloud
Takes upload while you're still recording them, so a laptop that crashes mid-set has already saved everything up to that point. Optional, and off by default. Pricing.
Band pages and the practice room
A page per band, created from inside the app. Bandmates open the material in a browser, practice against the band minus their own part, and leave a take for review. Free to host from your own studio, always-up on the subscription.
Linux
Ubuntu Studio on affordable mini-PCs, with the same engine and the same fixed 32-sample block. A build guide and a first-boot installer come with it.
Phone app, standalone
Record with the phone's mic and camera into a session, then sync it back to the studio.
DAWs without borders
Run it inside the DAW you already use
JWS4Live and JAMWireStudioRPP put JAMWire Studio's engine inside the DAW you already open every day. Project Rosetta is what makes the trip between them lossless.
JWS4Live
JAMWire Studio as an extension inside Ableton Live: the same 32-sample engine, tracks and racks, running alongside Live's own on one clock.
JAMWireStudioRPP
Run JAMWire Studio from inside REAPER: the same engine reachable without leaving REAPER's own session.
project_rosetta
The session converter, extracted and open-sourced: OpenTimelineIO in the middle, a faithful translation into each DAW and editor format, and a list of exactly what carried over. What it means.
Further out
Later, and one thing we're waiting on
Playing together over the internet
Three rungs, each with a benchmark: wired-LAN sessions with under a millisecond of added latency; internet sessions on Network Latency Tolerance, where every player is aligned to the same negotiated delay; and a shared-looper mode for any distance, where players layer against each other's previous pass.
Network Latency Tolerance
Your brain already compensates for a fixed delay: with headphones on, fingers adjust to it within minutes, up to a threshold that's different for everyone. A wired connection can generally hold that under 30 ms end to end, comfortably inside it. Network Latency Tolerance shares one delay-compensated mix across every player, so you're both adjusting to the same offset instead of two different ones, which is what keeps a pocket together at a distance. Turn it off for the lowest latency to your own monitor, and a looser feel against your bandmate.
Hardware guide and starter kits
A build guide for a barebones mini-PC that runs the Linux version, then small batches of sealed-component kits with the installer, then a validated configuration with a vendor.
Windows
The engine goes where the OS can keep a fixed 32-sample buffer on any class-compliant interface. Microsoft has announced an in-box low-latency USB audio stack; when it ships and can hold that buffer, a Windows build is on the table, with no date set.
