I highly encourage folks to check out a new DAW called Blockhead. It upends a lot of typical ideas of how a DAW should work. There’s no MIDI events and no global tempo.
Everything is represented as blocks of samples on rows of timelines which are then effected by transforms placed on the rows above the rows containing samples. Edits and transform adjustments all happen in real time, and everything is continuously rendered to a scratch buffer that can also be dragged in to the project as a new block of samples.
It is truly a very creative approach and when you see it you will be wondering why nobody tried this approach before. The developer, Colugo, has a new video on YouTube showing how it’s main features work.
