Hey,
I'm very new here but try to be as accurate as possible.
I built a simple 8-Step sequenzer to start with.
My problem is that as soon as I tick the DSP there is a harsh high pitched buzzing sound.
Apparently it's intependent of what I built 'cause it works fine on my friends computer and the noise is still on when the sequenzer is off. I played arround with the latency which didn't help. My input is the mic and my output the standard speakers.

It would be great if someone had an Idea.

Cheers in advance,

if the input is connected directly to the output, you're going to hear the sound of your mic/amp/dac/adc signals, as well as any feedback of these signals. it depends on your audio set up. Perhaps if you upload the patch and describe your audio set up in more detail? for instance, what mic and audio interface are you using? how is the gain on the preamp set?

ok I'll just attach the file. I use an Akai Lpd 8 midi controller to move the sliders. My input says: microphone (Realtek high definition)
My output: speakers (Realtek high definition)
thx

have you played around with the sample rate and block size? what are they set to? You're on windows right?
really I have no idea, I assume other applications are working fine?

also make sure you have the latest drivers

i had the same problem - i discovered it was because i had a dc offset in my final signal - putting a [hip~ 10] immediately in front of the [dac~] solved the problem
