Hi,
I have a Drumbrute, a Keystep and a Beatstep Pro. All three synced through the clock ports. All three are connected through USB with a powered USB hub, which in turn is connected to an iPad or iPhone for playing soft synths using the camera connection kit. All machines are also connected via Midi to a Midi patchbay to control the hardware synthezisers.
It all works like a charm, but I hear a high noise (kind of a fluctuating high note) when I connect the iPad or iPhone via the camera kit. Note that the I use the ground loop adapter of the Beatstep Pro, on one side connected to a USB charger, on the other side to the Hub to drive the synths.
It looks like a kind of ground noise.
Anyone has any ideas how to get rid of this sound?
Thanks for helping.
