It used to need a six-figure workstation.
Classical take editing. Now in your browser.
Ensembles cannot punch in. You record full takes and stitch the best passages together — that is how classical records have always been made. This is the first browser-based editing room built for that craft.

There is no punch-in for an ensemble.
In pop production you can re-record the same bars until they are right. A string quartet, a choir, an orchestra cannot: everyone plays the piece top to bottom, take after take. The second theme was perfect in take 1, but the coda sang in take 6 — it happens every single session.
Professionals write take numbers into the score and stitch the performance together bar by bar on specialised software. The technique is called source-destination editing — and for decades it lived only inside a handful of studios, on tools costing thousands.

What is source-destination editing?
Your takes sit in the source pane; the finished timeline grows in the destination pane below. You choose the best passage from any take and set it into the whole. European recording culture calls this work “montage”. KUON MONTAGE inherits that name, built for every recording made in full takes — strings, piano, voice, chamber music, choir.
Select. Compare. Replace.
The real screen: four takes, anchors A–D, an edited timeline and the edit plan.
Only what the editing room needs — but deep.
With respect to the great workstations.
This craft was built by great workstations — Pyramix, Sequoia. KUON MONTAGE does not replace everything they do. It brings the core workflow within everyone’s reach.
| Aspect | Workstations (Pyramix / Sequoia) | KUON MONTAGE |

| Source-destination editing | Yes | Yes (first in a browser) |
| Matching points across takes | Manual | Auto-estimated + manual fine-tune |
| Price | From several thousand dollars | $149 one-time / included in Concerto |

| Multitrack bundles, plug-ins, DSD | Yes — this remains their domain | No (WAV up to 8 channels per file) |
The road continues after the edit.

Answered before you ask.
What is source-destination editing?
You choose the best passages from your takes (the source) and set them into a finished timeline (the destination). It is the standard method for editing classical sessions, also known as “montage”.
Why can’t classical sessions punch in?
Several musicians play at once and the hall’s reverberation is continuous. A partial retake never joins cleanly — so you record full takes and stitch them afterwards.
Does the audio quality suffer?
No. You monitor on a lightweight preview, but the export stitches your original WAV files with sample accuracy — same bit depth, same sample rate.
Which formats are supported?
WAV and RF64 (over 4GB), from 44.1kHz to 384kHz, 16/24/32-bit, up to 8 channels per file. All takes must share one sample rate and channel count.
Is my audio uploaded?
No. From import to export, everything happens on your device. An unreleased performance never touches the network.
How does it differ from Pyramix or Sequoia?
The core source-destination idea is the same, but KUON MONTAGE is an editor only. Multitrack bundles, third-party plug-ins and DSD remain workstation territory. In return you get automatic take matching, zero installation, and a $149 price.
Standalone or subscription — which one?
Standalone ($149 one-time) means owning MONTAGE outright. Concerto (¥1,980/month) adds KUON MAXIMIZER, KUON DAR and 30+ other apps. If you only edit, buy it once; if you finish records too, Concerto.
Can I edit multi-file spot-mic bundles per take?
Today one take is one file — including poly WAV up to 8 channels from field recorders. Separate-file bundles are under consideration as requests come in.
A tool born inside the editing room.
KUON MONTAGE was designed by the artist Kotaro Asahina, who has lived with recording for 35 years — writing take numbers into scores, chasing joins late into the night. He built this so the craft could belong to everyone.
