Hi,

Thanks everyone who posted thoughts on the filters! 

Regarding the 121 filter, It's probably just me I don't like the way 
the resonance behaves, I don't get the same amount of resonance on 
different filter frequencies. I don't like the way it works for bass 
sounds. But I do use it alot for hihats and stuff like that.
 One filter I love is the filter in my mono/poly. So i've been 
looking at the A-105 too. But I need a filter with band/highpass more 
right now.

I think I'm going for the 101-1 (as I said I have an MS-20 so that 
can do for the time.)
