Noise over USB


Recommended Posts

Hi, I’ve just got a new piece of kit and it’s causing me a bit of grief……..

 

Is noise (high pitch hum) normal when using USB for midi?

 

I have just bought a blofeld and it’s connected to my iMac via USB, an M-Audio Oxygen8 is also connected to the iMAc via USB.

 

The audio outs of the blofeld connect to an Edirol FA66.

 

All works OK but I have to crank the inputs up on the Edirol to get a good enough signal but when I press a key on the keyboard I can hear noise.

 

If I connect the blofeld via MIDI to the Edirol but keep the keyboard connected via USB the noise isn’t present.

 

I don’t have any other hardware to see if it only happens with the blofeld so I’m just wondering is this type of thing normal?

 

Wayne.

hi, yeh, ive got this as well mate, i use a roland sh-201, and when i have the outputs connected at the same time as the usb i get a high pitched noise. i generally use the two seperatly, when i want to record the synth i un plug the usb, and when i want to control software i unplug the out puts of the synth!

 

im sure this is a bit backwards though, :P
