Scratch sounds without a turntable? It's easier than you might think, using the envelopes, filters, and sample start controls in Simpler. DJ Tech Tools' Mad Zach lays it down in this video: Grab the template as a free download from DJ Tech Tools.
You're probably familiar with changing control values in real time in Live, as well as sequencing them with envelopes and automation editing. Mapulator, a new free Max for Live device from DJ Tech Tools contributor BentoSan, is a hybrid of these two methods. Set a custom control mapping (similar to an envelope), then scrub back-and-forth through it with Mapulator's "Smart" control knob.
