First and foremost:
A NEW BUILT-IN OPERATING SYSTEM: “NUMBER NINJA” designed by Renoise team utilizing Renoise-style graphics and performance. (So that we can boot from Renoise and dump MicroScoffed WhineDuhs forever)
A’ight, when that’s covered, I could throw in a coupla useful features more.
Built-in Mayan calendar with an automatic beep on 21.12.2012 (8 a.m. preferrably)
A new automated master-track parameter - “total weirdness”
Scriptable script editors for scripted scripts.
Normal VST automation recording (recording from VST GUI knobs) and proper multitimbral VST handling.
1)pattern arranger similar to playlist editor in fruityloops
2)vertical (diskop) browser on the left of screen similar to fruityloops browser
3)Slicer in sample editor
4)Expanding the patterncommands beyond hex for new implementations
5)Scripting
Scrap the confusing “Excel” interface and use a piano roll or a real note staff.
Include a few dozen VSTs that nobody will use but which you can use as an excuse to increase the price. Add everything including the kitchen sink. Increase the minimum requirements to run the program.
One mixer is not enough. Make at least 3 mixers, all with different options so that users can get lost.
A multiple window interface and a floatable transport bar. This way, one can have a zillion windows open to impress clients/pets.
Backing of very large corporation. Increase the price to 3 figures and make a gimped affordable version nobody will buy.
