Dave Smith Instruments SYNTHESIZERS

many single instrument sounds don't cover a lot of frequencies at 
once at high levels.  you may already know, but the low-pass filter 
cuts out higher frequencies (essentially the more "treble" range 
frequencies) progressively as you close the filter.  What this means 
is that if the sound you are filtering doesn't cover many lower 
frequencies, and you close the lowpass filter... things will get 
quiet quickly long before you reach the bottom of the cuttoff point.  
the same goes for low frequency sounds without much high 
frequencies... you open up the filter and at a certain point much 
before it's completely open there will be little audible change.  So 
what you have to do is limit your modulation to sweep the most 
effective frequencies.  In the case of your Black Sabbath music 
running through it... you noticed a big difference while sweeping the 
music and that is because it was a full instrumental set you were 
filtering which covered a wide range of low, mid and high 
frequencies.  You know the evolver is full of modulation sources... 
if you tune these well to modulate the filter within more focused 
frequency ranges, you will be able to tune your sounds more 
effectively.

tip 2:  sound gating in combination with filtering can lead to making 
many external audio sources have synth like qualities.... what I mean 
is, learn how you can control making a sound louder.... slowly moving 
towards softer.... and cutting off and then kicking in volume at any 
time you want, on command.  

tip 3:  gating the noise level (you know what a noise generator is?) 
using the external in can add some neat things to your sound.   The 
evolver has a pretty nice distortion effect built in.... if you feed 
that a gated noise signal along with your guitar sound, you can make 
it "fuzz" a bit more :).  

tip 4:  turn up the level of a delay line and modulate time below the 
100 milllisecs line... great for flanging effects.  tune the feedback 
level.
