An audio player with transport, scrubber and volume; an equalizer and a visualizer; a playlist; a cassette, cartridge and record that turn while they play and hold where they stop; piano keys, a step sequencer and a tracker you can type into; a waveform, a 16:9 video frame, an image compare, a gallery, a filmstrip, a record button and an FM tuner. input exports SlideBase, the undrawn rail its sliders share; the gallery treats exported Bases as building blocks, not components. pixel's micro font gains '#' for notes like C#4. pixel.Pad and the slide rail read input only while their base is enabled, so Inert or a fresh Disabled stops a drag or a key already sent. AGENTS records why a drawn container keeps the DISABLED description: MyGo paints a disabled subtree at half opacity.
