## What is Quantachrome?

A simple 2 oscillator stereo synthesizer, with a unique visualizer meticulously designed to convey real concepts of musical harmony visually.


## Version history (last 2 releases)

### 1.0.1 — 2026-05-23

Quantachrome 1.0.1
  
  Synth
  - Default amp envelope now has 10 ms attack and 10 ms release instead of 0 ms / 5 ms, eliminating the
  click on note start.
  - Fixed a low‑frequency thump at the end of the filter envelope's release. The cutoff is now smoothed
  (≈5 ms time constant) so the biquad coefficients can't snap when the envelope collapses to its floor.
  
  Settings UI
  - Every numerical setting is now directly editable — tap the value to type in an exact number. This
  includes filter cutoff, resonance, all four ADSR stages of both envelopes, pan, glide, and max voices.
  - Sliders now support drag‑down fine control: while dragging the thumb, slide your finger downward to
  scale up precision (the further down, the finer the horizontal motion). Lets you dial in exact values
  without zooming or arrow buttons.
  - Tapping anywhere on a slider track now snaps the thumb to that position (previously you had to drag
  from the thumb).

  Keyboard
  - New Keyboard → Opacity setting (0 – 1) controls how visible the on‑screen keyboard is over the
  visualization. At 0 it's hidden entirely and won't catch touches. 
  - The on‑screen keyboard (and its octave bar) automatically hides whenever a hardware MIDI device is
  connected, and reappears when it's unplugged.

### 1.0 — 2026-05-21
