@Lindon say that your "volume is set at 0.5, you set an lfo , depth on lfo set to go from -0.2 to +0.2 then the volume should go from 0.3 to 0.7.
As it stands it would go from 0.1 to 0.5
So current lfo can not go above center value!
If it were correct.
You would set the lfo to have an amplitude/depth of 1 or -0.5 to +0.5 and it would fully close and fully open...with a center value of 0.5.
Or 0.8 and it would go from 0.1 to 0.9 etc.
So the lfo should get added to the center value , increasing and decreasing the center value.
In the case of a filter it would open and close the filter up and down from the set freq.
Now , as an option it could work as it is now .......up to the value set and even reversed where it would go up from the value set ...but default should be up and down from the value set.
As for the adsr it should go from the set value and increase the value , not from 0 to the set value .
With an option to inverse...go down from the set value.
None of the modulators work like they should , its wrong and makes it impossible to emulate a synth the proper way.
