An object of the invention is to provide a method and a device for manipulating signal flows for the purpose of obtaining an increased entertainment value when playing audio.

The invention provides for this purpose a method for live manipulation of signal flows via a controller, wherein the method comprises of: feeding in a first signal flow and a further signal flow, each having X signal flow layers, wherein X is greater than 2; separating the signal flow layers from each signal flow into a respective series of sub-signal flows, related to the signal flow, as according to a predetermined ratio, wherein each sub-signal flow has Y sub-signal flow layers, wherein Y is smaller than X; reading a desired ratio between the first signal flow and the further signal flow via a controller; merging corresponding sub-signal flows as according to the desired ratio in order to obtain a modified series of sub-signal flows; feeding out the modified series.

Within the context of the invention, manipulation is defined as mixing flows. Manipulation optionally further comprises at least one of adjusting tempo and/or pitch of the flows, inserting additional sound fragments and adding effects to the flows. It will be apparent to the skilled person that effects are adaptations of the flow, such as: flanger, gain, delay, reverb, phaser and so on.
