Here we see Harmor’s default Volume Envelope: In this tutorial, we will use Image Line’s Harmor synth to create a sweep/riser.
However, creating sweeps in a VST instrument can provide much more flexibility and control over the sound and understanding how to make them will allow you to create some really nice transitions. This is just fine and still proves to be a good way of creating sweeps, especially with a lot of the pitch preservation tools allowed with stretch functionality in current DAWs. One of the old school methods of making sweeps was to take a stab or single note hit and reverse the playback of the waveform. These sounds are commonly referred to as sweeps, and when it involves pitch or frequency increasing it is called a riser. Creating tension in transitions and breakdowns usually involves a sound that increases in volume and intensity as it nears the next phrase (usually an 8 or 4 bar segment where the music changes).
