…oard. The panel view is improved after re-measuring on a real keyboard. Colors have been changed a bit in order to improve contrast. Three new views have been added: 1. a Full view of the keyboard, including the controls to the left of the keyboard, specifically the Pitch-Bend and Modulation Wheels and the Patch Select buttons, as well as a representation of the floppy drive and the little "storage compartment" above it that is a bit of a characteristic shape. 2. a "Compact" view that includes all the controls and a 37-key (3-octave) keyboard that may be both legible and playable at the same time, on a reasonably-sized touch screen. 3. a "Tablet" view of the front-panel controls, with the display and buttons stacked vertically instead of stretched horizontally, as well as the "Patch Select" buttons. This view, together with a MIDI keyboard controller, this should give users a reasonably workable facsimile of the real thing: Keys, Pitch Bend and Modulation wheels on their MIDI keyboard controller; all the keyboard-specific controls and the Ensoniq-specific Patch Select buttons on the "Tablet" view. The Full and Compact views also include a keyboard: the full 61 keys and a reduced 37 keys respectively. These work, tracking pointer events, and generate not just key-down events with velocity, but also per-key "pressure" or "aftertouch". Velocity is simulated by position of the click/touch; Pressure by movement of the pointer on the key while down. Both are also animated: Velocity is shown as a colour between blue (1) and green (127), Pressure between yellow (1) and red (127).

@galibert This seems fine to me, if I hear no objections in the next 24-48 hours, I'll merge it. |

This is implemented using analog i/o ports, one for each key, setting the value to pass the key's velocity and pressure. I wasn't able to find a specific type of analog i/o port so I am currently using
IPT_PADDLE, which is probably not ideal, but it does work. I'd be delighted to use a more appropriate type, if there is one (or if I can relatively easily add one in a way that ).
