> You reviewed three DAWs.
There's definitely more than 3 reviewed there? Sure, a lot of them still say [TODO] on getting a review, but then I don't want to review something I don't have a significant amount of 1-on-1 time with. Maybe you didn't realize there are click-able tabs?
Also, the way you phrased this came off as quite rude. There is someone on the other side of the screen, and you'd do well to consider that in the future.
> Re: MIDI - you can already "play between the notes" using either MTS or even just simple pitch bend [...]
Pitchbend is global to the track, if you play a chord and bend, all of the notes bend equally. With MPE it is possible to bend a single note, but then MPE isn't supported in every DAW (FL Studio doesn't have it) and my gripes with MTS are explained already: You're still working with only 127 possible notes so you limit your octave range. Worse, with all of the microtonal solutions, the UI will still typically look like a 12-tone piano. This is sort of okay for 24TET, but It's immensely confusing for anything else.

They really haven't been true for audio for a while now. Moore's law isn't dead, but definitionally "Moore's law is the observation that the number of transistors in an integrated circuit (IC) doubles about every two years" doesn't equate to all work loads seeing an improvement. Audio is a pretty latency sensitive, mostly strictly sequential workload. Making audio code that uses multiple cores often isn't even possible. Audio needs clock speed and IPC gains, which we have gotten, but that's not always enough. I have a 5900x and still hit limits. What would you recommend I do, get a Threadripper or Xeon so that I can have even more cores sit idle when making music? If anything, the extra cores have been a hindrance lately - on my 3900x I had before at high loads I had to pin the processes to one chiplet or I'd me more likely to get buffer underruns. It's not as if anyone is arguing that CPUs getting faster so quickly means that we don't need graphic cards.
UAD exists but then you're limited to their plugins and their accelerators are quite expensive for not being really all that powerful. I'm also not convinced that kind of accelerator is even the right approach. Field Programmable Analog Arrays, FPAAs, for example, could be setup with a DAC and ADC on either end. Or we could make DAWs/OSs capable of handling digitally connected analog "plugins" better - think effects like the Big Muff Pi Hardware Plugin [1] or Digitakt with Overbridge [2] (These are the only two examples I know of!). Using the word "Acceleration" was wrong, what I really meant is offloading. We need a way to offload the grunt work to something we can easily add more of or better fits the task. I think this is particularly true of distortions, as slamming the CPU with 4 or 8x oversampling to get a distortion to not sound awful hurts.
