Find a way to make sliders control all rows alternatively, but to have only one audioParameter for it, that could be assigned to a midi controller in the DAW

[dmultiply]

The row slider allows to choose which sequence is controlled by the sliders Attack, Sustain, Interval, Pulse, Offset, Gain, Frequency and Resonance.
Each row has an audio parameter for all of this controls. And a slider attached to it.
When row slider is moved, the slider for the row chosen is displayed, and the former slider is becoming invisible.
With this method, all the audio parameters are available to the user, but we want to be able to manipulate only one set of controls, that are able to act on all the rows, depending of which row is chosen.
But audioParameters can be attached to only one slider at a time, so need to find a way.
