Faderfox EC4

Supercollider class for interacting with Faderfox EC4

Allows for controlling parameters with 14bit NRPN and 7bit CC values.

f = FaderfoxEC4.new("nrpn"); // "cc" is also valid option.

    var sig, env, verb;
    sig = (SinOsc.ar(\freq.kr(300)) * \vol.kr(0))!2;

    verb = NHHall.ar(sig) * \verbAmount.kr(0);

// IT IS SUPERIMPORTANT TO USE '.asMap'.
// otherwise we use the underlying control `Bus` number as a value, 
// and it can get loud.
