Four rates and four levels, 0 to 99. Levels are 0.75 dB a step and segments move at a steady dB a second, the rate doubling every 6.2 steps. A rising segment jumps to -44 dB and slows as it climbs, and ratescale speeds every segment up the keyboard.
Six osc::fmop and six env::dx per graph, wired as the algorithm, with the panel's knobs per op: ratio, detune, output level, velocity sensitivity, four rates and four levels, plus feedback on op 6 and rate scaling. Each ships as a sound: electric piano, bass, brass, organ.

A DX7-style six-operator FM synth, built as graphs: in keeping with
osc::fmop's "the graph is the algorithm", each algorithm is its own file.env::dx(new plugin): the DX7 envelope. Four rates and four levels, 0-99, levels at 0.75 dB a step, and segments moving at a steady dB/s with the rate doubling every ~6.2 steps. Rising segments jump to about -44 dB and then slow as they climb, as the hardware's do.ratescale(0-7) is keyboard rate scaling.playends once the release reaches an L4 of 0.dsp/dx5.dsp,dx16.dsp,dx22.dsp,dx32.dsp: sixosc::fmopand sixenv::dxeach, wired as DX7 algorithms 5, 16, 22 and 32. Per op the knobs are ratio, detune (cents), output level (0-99, in the envelope's dB) and velocity sensitivity (0-7, up to 25 dB), plus four rates and four levels. Each graph also has feedback on op 6, rate scaling and output. A modulator at level 99 swings its target's phase by 8 radians. They ship as an electric piano, a bass, brass and an organ.Testing
