changable logartimic (curve of LFO or ENVELOPE)

were we have to add this to the lokal makefile:
ORGINAL PROBLEM POST
Hei.
I have made now, a LFO (UP/DOWN Ramp & Triangle), now i need to add a logaritmic ammount to get CURVES/SINEs on the LFO Straight Lines, i want to do this with a Encoder.
My LFO Values going from 0-65535 (16bit, AOUT-Ready)
My Curve CC also goes from 0-65535 (Curve means Logaritmic)
I have to execute this code every milli seconds, to change the AO
... Always More! ;) Width modulation added, with it you can achieve ramp down/up, pseudo sine(this is not true sine) and many more from a single triangle waveform:
// calc an unipolar triangle(0 to 65535) depending on x(time) between 0 and 65355 and phase between 0 and 65355
// set the phase
u16 time = (u16)(x + phase + (u16)(wide_mod/2)) ;
// apply pos/neg width modulation, wide_mod is an unsigned 16bit ;)
float wide_pos = 65535.0/wide_mod;
float wide_neg = 65535.0/(6553
