After the Gain, the Pitch and the Mix, the Pan is the next node that is just one number. It now gets the same device in the graph instead of a row for its pan. - PAN_DEVICE: the Gain's 160x160 plate in cyan with one bipolar knob for Pan. The middle stands straight up, and the turn goes evenly to L and R, which are engraved at its ends like A and B on the Mix. - PAN_TAPER in hardwareView is 1, so left and right are heard alike. Device and unit test read the same constant. - PAN_ROW is exported from the core, so the knob has the node's range. - A linked Pan greys the knob, as for the Gain. - The test hook __gm.pan.panel returns the same shape as the Gain's. - No instrument preset uses a Pan, so no preset columns change. Tests: - Unit hardware-view: 17 tests, 2 new (the turn, and L and R inside the plate and clear of the screws). Counter-check: PAN_TAPER 2 turns the turn test red. - e2e 34 (melektaus-atx): 135 checks, 1 new. - Gate (melektaus-atx): 287 files, 4399 tests. - Pictures looked at: Gain, Pitch, Mix and Pan in a row, Pan at -0.35.
