0.2.0

Pitch can now be drawn as notes, the sheet can leave the app as sound, and the session survives quitting.

Pitch as notes and octaves. A twelve-row note band over an eight-row octave band, the shape of Oram's own later design. Mark it with dots, where each mark sets a note that holds, or with lines that are followed as they move. Pick a key and a scale and marks snap to it; chromatic by default. What the machine reads is drawn over your marks, so what you see is what plays. The Hertz strip is still there and still the default.

Audio and MIDI out. Export Audio renders one pass of the sheet offline, faster than real time, so there is nothing to record. Export MIDI comes from that same render and is written from what the machine actually played, with vibrato and glides as pitch bend and the amplitude contour as expression. The two files line up.

It remembers. The drawing, the slides and every setting are kept as you work and restored at launch.

Timbres. A preset menu on each slide: sine, saw, square, supersaw, detune and blank. Supersaw and detune add detuned voices, drawn on the glass as orange echoes. Each timbre has a pan setting, heard with Mono switched off, and the engine renders in stereo.

Effects strips. The vibrato strip can be switched to a delay, where the line's height is the echo time. The reverb send can go to a plate or to a room.

Also: the projector window works in the packaged app, where it had been showing nothing. Clear (⌘N) starts a fresh sheet. Space plays and stops. The brush on the slides has a solid edge. Rewind shows itself when the transport is stopped.

macOS builds are signed and notarised. On Windows, SmartScreen will warn: the build is unsigned there.
