Totally agree, although my bias tends to slot that more into the category of sound design rather than composition, even though modular has a way of blurring or obliterating such distinctions.
I feel that what I’m talking about can potentially complement a modular approach. I’m just finding, as I (too slowly) make my way through The Geometry of Music, and Modalogy, that in spite of my love for Partch, and raga, and maqam, and microtonality, etc, the fact remains, I was born in USA, raised on rock and roll, blues, and (on the very good days) jazz. Quantized chromatic pitches and their harmonic relationships have worn deep deep grooves in my brain. I love to challenge those sensibilities, but at other times I dearly wish to indulge them as deeply as I am capable of.
And I’m always looking for more efficient ways to accomplish that. Not the least of which, so that I can get through the books I mentioned above more quickly!
Wanted to mention a really beautiful piano roll I encountered recently. Helio workstation has lovely interaction design for zooming, scrolling, and note manipulation. Unfortunately the Mac version is crashing when it scans my plugins, so I need to try the other versions. Fortunately it is quite cross-platform (including Windows, iOS, and Android).
I also need to remind myself why Touchable didn’t gel with me as an Ableton MIDI clip editor. And another option altogether is bitwig on a Windows box with this Dell 2714T touch monitor I own (that sadly lacks Mac drivers).
But given all of the above, I think I’ve backed off the “build a 512” cliff for now.
