This past week, Reason 7 and the Traktor DJ app for iPhone saw a release, a video investigated the history of Bob Moog’s original ladder filter design, Attack Magazine shared some tips on programming shaker rhythms, and Ableton teamed up with a Polish sound-design firm to give away a comprehensive sample pack. It’s all inside the latest edition of This Week in Music Tech.

Propellerhead released version 7 of its flagship software this week. The considerably updated Reason program brings many new and revamped features to its platform, including a more streamlined recording process, the ability to send MIDI information out from the program, and a variety of new synths and FX—most of which are covered in the video above. Producers interested in trying the program before coughing up $400 to buy it (or the $129 it takes to upgrade from Reason 6), can download a free demo of version 7 program here.

Following just a few months after its release on the iPad, Native Instruments’ Traktor DJ app was made available to use on the iPhone and iPod Touch. The new, condensed edition of NI’s powerful digital-DJ app can be purchased now for the agreeable price of $5 over at the iTunes store.

Perhaps as a way to further celebrate Robert Moog’s recent induction into the Inventors Hall of Fame, Moog Music shared a new video which highlights its synthesizer’s pioneering ladder filter. The brief clip—which takes an in-depth look at the essential synthesis component—covers the history of Moog’s unique ladder filter design before launching into a pretty nerdy discussion about its importance throughout the years.

Another edition in Attack Magazine‘s helpful Beat Dissected series surfaced this week, supplying readers with valuable insight into the elusive art of programming realistic shaker sounds. The online publication does its best to break down the process into three easy-to-comprehend steps on Beat Dissected: Organic Shaker, which can be read here.

Though we just missed this piece of news last week, we hope you’ll agree that it’s really never too late to share free stuff. The audio experts at Polish sound-design firm Waveforms recently teamed up with Ableton to give away a free sound pack consisting of 24 unique loops and over 100 individual kick, snare, hi-hat, and percussion samples—all of which come organized in a convenient Live session file. The sample pack can be downloaded for free, here.
