// -----------------------------------
// Automatic measurement methods
// Currently support auto-measurment of the following
// Amplitude Envelopes: A D and R
// Modulation Envelopes: A D and R
// LFO
// -----------------------------------
// How to measure Amplitude Envelopes:
// Sylenth (Amplitude Env Attack, Decay and Release)
// Init:
// AMP ENV A: A = 0, D = 0, S = 0, R = 0
// Then step through the A, D and R steps and measure
// Attack: for (float paramValue = 1.0f; paramValue >= 0.0f; paramValue -= 0.020f)
// Decay: for (float paramValue = 1.0f; paramValue >= 0.0f; paramValue -= 0.020f)
// For Release you have to make sure the Sustain is full.
// Then send a short midi message and measure the length of the tail
// Release: for (float paramValue = 1.0f; paramValue >= 0.0f; paramValue -= 0.020f)
// How to measure Modulation Envelopes:
// Sylenth (Mod Env Attack and Decay):
// Init:
// AMP ENV A: A = 0, D = 0, R = 0, S = max (10)
// Mix A and Mix B = 0
// Master (Main Volume) = half (5)
// Mod Env A destination: "Mix AB"
// Mod Env A destination amount (ModEnv1Dest1Am): max (10)
// Mod Env A: A = 0, D = 0; R = 0, S = 0
// Then step through the A and D steps and measure
// How to measure LFO:
// Sylenth:
// Init:
// AMP ENV A: A = 0, D = 0, S = 0, R = 0
// LFO Gain = Max (1)
// LFO Rate = Min (0)
// LFO Wave = LFO_Pulse
// OSC VOL = Half (0.5)
// OSC Wave = OSC_Pulse
// SYLENTH_PARAM_XMODLFO1DEST1AMOUNT = Max (1)
// SYLENTH_PARAM_YMODLFO1DEST1 = YMODDEST.VolumeAB
// Then through the LFO steps and measure
// for (float paramValue = 1.0f; paramValue >= 0.0f; paramValue -= 0.020f)
