>It's the 303. The noise you hear is noise from the digital
circuitry getting
>into the audio path within the TB303. The sequencer's
microprocessor and
>associated circuitry causes a significant amount of electrical
noise, which
>is what you're hearing.
>
>Specifically, most of the noise is being caused by the scanning
signals

and off at a
>rate of several hundred Hz. It is the large voltage spikes from
this
>switching that causes the interference. (LEDs take lots of
current;
>switching this current causes voltage spikes, which means
trouble).

>The rate of this 'siren' noise is related to tempo simply
because the rate
>at which one of the LEDs is flashing is proportional to the
tempo setting.

>My TB303 makes this noise. I must confess I haven't listened to
your mp3 but
>I can imagine it's pretty much the same. But strangely enough,
another

appears to be
>much 'quieter', and everyone else I asked about this before
didn't seem to

>I did try to eliminate the noise in my 303 by replacing various
electrolytic

but I didn't

was down to the
>board layout / general design, or because of a bad PCB ground
plane in my
>303 (the board got cracked in half by it's previous owner).

>Shaz, since you've encountered this noise yourself, I'm tempted
to open my

eliminate it.

with.
