// controller.

// This is done by providing a set of remote control pages organized by section.
// A page contains up to 8 controls, which references parameters using param_id.
//
// |`- [section:main]
// | `- [name:main] performance controls
// |`- [section:osc]
// | |`- [name:osc1] osc1 page
// | |`- [name:osc2] osc2 page
// | |`- [name:osc-sync] osc sync page
// | `- [name:osc-noise] osc noise page
// |`- [section:filter]
// | |`- [name:flt1] filter 1 page
// | `- [name:flt2] filter 2 page
// |`- [section:env]
// | |`- [name:env1] env1 page
// | `- [name:env2] env2 page
// |`- [section:lfo]
// | |`- [name:lfo1] env1 page
// | `- [name:lfo2] env2 page
// `- etc...
//
// One possible workflow is to have a set of buttons, which correspond to a section.
// Pressing that button once gets you to the first page of the section.
// Press it again to cycle through the section's pages.
