MultiTrackStudio: Tips, Tricks, & Updates (Last update: v. 2.9 on Nov. 14, 2017)
I'm going to start this thread just so I can update everytime MTS updates and adds new features, since the developer is literally improving this app in significant ways every 30-45 days or so. For example, v. 1.5 added a Matrix Sequencer that was part drum machine, part automated Audio and MIDI trigger sequencer - really damn cool.
(EDIT: Visit this thread for some screenshots and discussion of the v. 1.5 update and what the Matrix Sampler can do. This was a free addition to MTS, not an IAP.)
While not as sexy as the prior update, v. 1.6 has a chance to be an even more useful update if he gets some of the IAA compatibility stuff worked out. This update interests me for two reasons: (1) When it works, MTS is ELITE for workflow convenience because you can hook up your synth apps, sequence them, control with a variety of MIDI controls, and record all from the same app over IAA. But IAA is inherently wonky and some of the apps just weren't working well with MTS, if at all. (2) It is possible to use MTS as a MIDI controller/sequencer and then record the results using AudioBus (this would be a nice alternative if IAA isn't working right) - this update purports to improve how that works.
I'll post later with some impressions if/when I get a chance to try any of this out. It's not a "cheap" product ($30 U.S.), but the developer is just excellent and it's even supplanted Auria as my DAW of choice. Don't regret a single cent spent on it, as should be the feeling with any quality product.
