Re: Ways to limit the LFO range...

2006-06-26 by ilanode

Sorry, for the insufficient explanation. I'll try again. You go from 
the LFO's sine out into a VCF. Let's assume you take CV1 of the 
A120. This input is calibrated to comply with the 1/V standard. The 
sine output goes (just a guess) from -2,5 to +2,5 thus will swing 
the freq. as if you would manually turn the freq pot over a wide 
range. This is the current annoying situation. However, if you use 
the CV2 or CV3 input you can attentuate the incoming sine wave with 
it's corresponding CV-pot to any range inbtn. 0V and -/2,5V. The 2 
attuators (CV2 and CV3) make of the missing output level control on 
the LFO. Hope that helps, Ingo
