For some reason Iāve only just become aware of your excellent and, again, helpful response to my remarks.
Apologies for lack of formatting⦠Iāve yet to delve into how to partially quote you and reply in context as you did mine (Iām aware of what markup is, but different forums seem to implement it differently or not at all).
Your points 1 and 2 aboveā¦
I replaced my Akai with a (now legacy) Novation Impulse 61. I did so because as soon as I did finally kick my own backside and look into understanding the programming side of my Akai, I suddenly had an urge to learn to play a keyboard.
The course I thereby ended up purchasing (on Udemy. I find it outstanding value) brought me directly to realising that to even want to play a two octave scale would involve multiple button presses on the Akai. Not only this, but even the first stirrings of triads with their inversions made 25 keys way too prohibitive.
The Novation was very cheap on a local secondhand site (less than Ā£150), and the author of the github script for it was kind enough to update it to remove a last bug. So, I now have many more keys to play on, and itās fully supported as a controller. Itās also an instrument plus controller, so I have way nicer feeling keys. Nice!
Since then Iāve been focusing on finding my way around a keyboard. Since tihis is all a learning process, I havenāt even really opened my DAW in over a month! However, what I am noticing is that by now learning the keyboard and accompanying music theory, Scaler not only makes even more sense, but is going to become MORE rather than LESS useful! I thought I was purchasing a plugin that would help me avoid āall that darn theory and practiceā. In truth the opposite has happened.
As Iām learning the keyboard Iām having so many āaha!ā moments as it finally becomes clear (learning guitar is nothing llike the same experience!) how and why all the notes, their placement, and the very structure of Western music exists as it does. Wow, I never imagined Iād find it all so fascinating.
Not only fascinating but in starting to gain an ability to move beyond the single finger āplinkingā and actually start playing a keyboard (coughs), Scaler will come back to be a companion and assistant rather than some single hinge on which my entire use of chords would rely.
Okay so not really about āwhat do you want in Scaler 3ā, but always happy to chat with the nice people on this forum 
p.s, your point 8: canāt wait! Iām sort of dying to get back to playing inside my DAW, but in fact want to stick with some regular keyboard practice before I return to any production related activity. Unfortunately there are only so many hours in a day. One can dream of making music full time eh? 
[EDIT] also wanted to just add, in case anyone finds it useful: as yet Iāve had no issues at all running Bitwig with a 9th gen i3 even downloading one of the more complex project files included with Bitwig. Okay so it does now have 24gB of RAM (due to my inability to calculate 2 x 8!) but since memory was always going to be an issue, it wasnāt an expensive error
Further, I gave up completely with ASIO4ALL. I found it incredibly poorly implemented, it drove me nuts in terms of trying to configure the sound inside Bitwig, and in truth Iāve just gone back to the WASAPI driver native to Windows 10 and again, have zero issues at all, everything works perfectly out of the box, including automatic switching headphones, midi controller etc.
