If any one has any demos they would like to send me it would be greatly apperciated im looking for some new acts you can send them to:

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 >going to the illuminated LEDs, which are actually switched on 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 >TB-303 I have besides me which had been sent to me for repair appears to be >much 'quieter', and everyone else I asked about this before didn't seem to >notice this noise on their 303. > >I did try to eliminate the noise in my 303 by replacing various electrolytic >capacitors that were cruical for power supply decoupling etc. but I didn't >get anywhere. I just presumed it was either a 'feature' that 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 >303 up again sometime soon and make a bit more effort to eliminate it. >Especially since I've got another one sitting here to compare with. > >So, anyone else notice this noise? > >Trev > > >----- Original Message ----- >From: <[EMAIL PROTECTED]> >To: <[EMAIL PROTECTED]> >Sent: Friday, May 17, 2002 9:07 PM >Subject: [TB-303.org] Does your 303 experience the same trait as mine? > > > > from TB-303 resources mailing list > > -------[ http://www.tb-303.org ] ---------------------- > > > > Hi all > > > > I've always noticed this problem on my on 303. > > Well, to be honest... i'm not sure if it is a problem but a typical > > trait of equipment of this nature and my lack of recording experience. > > > > Have a listen (file size 1.35mb) > > > > http://members.aol.com/stormstown/siren303.zip > > > > In this example I have my 303 connected to the line input of my pc with a > > phono jack > > from output of the 303.
