Filters: subjective opinion required
2001-07-03 by Mark Deal
I'm looking to spoil myself rotten for my birthday and buy some new modules. Amongst other things, I'm considering an A122 low pass VCF (Curtis chip based) and a A123 high pass filter. Is the A122 worth having? Clearly the sound is going to be substantially different from a transistor ladder based design, but does it sound GOOD? I tend not to use large amounts of resonance in my music, so if this filter excels at resonant sounds but is pretty characterless otherwise I'm not particularly interested. I already have a Multimode filter, but am also interested in a dedicated high pass filter, but only if it offers me something sonically different. How does the A123 perform? I find the multimode to be quite 'lumpy'... It doesn't take much to tip it into self-oscillation. Is this filter smoother? Comments appreciated! Mark
