Samplebrain - v1.2.1

v1.2.1 — Freeze fix

Fixed

• No more freezing Live on long sources. When a brain source spanned a
  long arrangement, SampleBrain rendered and analysed the whole thing, then
  the synthesis ran long enough to lock the dialog — and with it all of Live
  (Escape stopped responding). Analysis is now capped to the first 30s of each
  source/target, so the plugin stays responsive no matter how long your tracks
  are. (Need more material? MAX_SOURCE_SECONDS in the source is the one knob.)
• Sample Design no longer re-synthesises in a loop when toggling sources or
  switching tabs — repeated triggers are debounced and stale renders dropped.
• Version label is now accurate. It used to be hard-coded; it now reflects
  the actual installed build.

Install: download SampleBrain-1.2.1.ablx, double-click, restart Live.
Requires Ableton Live 12 Suite.

Samplebrain - v1.2.0

What's new

Sample Design (new)

A new tab that turns the concatenative-synthesis output into usable samples:

• Pitch — transposed variations (varispeed; chromatic / major / minor / pentatonic strategies)
• Layered — stacked, randomly transposed copies (1/N auto-attenuation)
• Slice — cut into one-shots, auto-classified kick / hat / snare / tom / perc
• Automate — random pitch glides
• Interactive source waveform: clickable onset markers, zone selection, spacebar playback
• Export: clips on an "SB Siblings" track + 44.1k WAVs

Engine

• Smooth match engine (Viterbi unit-selection) alongside the original Greedy — polyphonic
• Target selectable from the dialog (switch it without reopening)
• Tabs: Synth / Prep / Sample Design (shared Target + Brain sources)

Fixes

• Synthesis clicks fixed (Tukey overlap-add window)
• Block size auto-clamped — no more "block size too large"
• GitHub update detection (a badge may now appears when a newer release is out)
• Permission-model compliance: reads/writes limited to the allowed directories, symlink-tolerant

SampleBrain v1.1.1

What's new

New controls & UX

• Spacebar toggles preview playback
• Cmd/Ctrl-click resets any slider to its default value
• Dark theme by default; version shown in the header

Clearer feedback (no more cryptic "Error 400")

• Explicit messages: no target selected / empty brain source / block size too large
• Unsupported dropped files (MP3, FLAC, M4A…) now warn instead of being silently ignored — WAV/AIFF only
• Generate failures are surfaced instead of failing silently

Fixes

• Fix 403 on /preview, /upload-file and /open (links, drag&drop and preview now work)

Security hardening

• Track names escaped in the dialog (XSS)
• WAV/AIFF parser guarded against malformed files
• Session token on the local HTTP server
• Upload path/extension whitelist

SampleBrain v1.1.0

What's new

New features

• Randomize button
• Drag & drop WAV/AIFF from Finder into Brain Sources
• Output level slider (amp weight)
• Voices (1–4) — polyphonic grain matching
• Pitch (±24 st) + Pitch spread — per-grain pitch shift with variance
• Reverse (0–1 probability) — grains played backwards
• Density (0–1) — rhythmic gaps by skipping grains randomly
• Waveform preview with ▶/■ Web Audio playback

Bug fixes

• Fix Generate producing no output / progress dialog never opening
• Render noise eliminated on slider moves (PCM cached per source)
• Fix Generate with dropped-files-only sources
• Dialog height 880→720 px — fits 900-px displays without overflow

SampleBrain v1.0.0 — First Release

SampleBrain v1.0.0

Port of the SampleBrain algorithm (Dave Griffiths × Aphex Twin)
as a native Ableton Live 12 extension.

---

Right-click any arrangement selection → the brain reconstructs
the target track's timbre using material from another track.

What's inside

DSP fully in TypeScript, zero external dependencies — Cooley-Tukey FFT,
MFCC, OLA, custom WAV/AIFF decoder. Three spectral analysis modes
(MFCC, FFT, mix), four windowing functions, and the three block network
parameters from the original: Novelty, Boredom, Stickiness.

Output lands on a new track, source stays untouched.

UI inspired by Ryoji Ikeda — dot-matrix, light/dark theme,
tooltips on every parameter.

Requirements

Live 12 Beta, Suite edition. Developer Mode OFF for installed .ablx.

Install

Drag & drop SampleBrain-1.0.0.ablx into Live → Preferences → Extensions.
