Reflection DAW
I've been having a dalliance with Reflection, a DAW currently under development that takes the philosophy and feel of my beloved AudioMulch and updates it for the 21st century. It honestly feels like I'm cheating on a lover.
The UI is excellent - it retains that wonderfully intuitive feel, and without even trying, my muscle memory is already being retrained. There are a few things I miss, but it's evolving at such a pace that I'm sure they'll be on board before long. Some of Mulch's more esoteric features, like the Metasurface, are already recreated pitch-perfect.
Best of all, 64-bit plugins are fully supported, which would mean a clean sweep of my old resources and starting again from scratch (maybe bridging a couple of old favourites). There's something appealing about that, a clean start with no safety net and discovering a new lease of creativity in the process.
Although I'm not a heavy MIDI user, some of the generative devices are brilliantly flexible for sequencing, and it also contains a DIY Lab for rolling your own plugins. It feels like a thoughtful intermeshing of some of the best aspects of Mulch, Ableton and even Max/MSP. Version 2 can be downloaded as a free demo. Highly recommended.
