Re: Trident mkI filter problem

2007-09-20 by roisto

I mean that filter of the last two oscillators has somehow turned to 
work negative. When cutoff filter is opened, one oscillator plays it 
closed (like lowpass effect), and vice versa, when filter is closed, 
one oscillator plays filter totally opened. Two modes at the Eg-mode 
seems to change this effect between 7th and 8th osc. Thank you for 
you reply.
