Well...This in my mind creates a LONG list of things that would make me not like any particular arranger keyboard (in other words if I designed one myself):

(Not necessarly in order of importance)

This list is about a TOTL arranger.

1) #1 is lack of TOP QUALITY PRO Workstation level sounds, especially acoustic sounds. If they can put them in a worksation they can put them in a arranger.
After all this is a musical instrument and without the great sounds...nothing else matters. (Also, many have technical problems with some of the sounds, and it can ruin a performamce). Of course currently we have a few sounds that are better than the WS's, Keep those :-).

Actually I want all the instruments to be superb, realistic, beautiful as if I am listening to the real thing. No vibrato, tibre, digital noise, volume, or other tech. problems.

2) Lack of quality styles for the music I play

3) Poor MIDI implementaton (it needs to be at the same level as a PRO workstation)also, EVERY button, slider etc needs to send AND respond to external MIDI data.

4) Lack of an OS with lots of great, musically useable functions

5) Lack of a touch screen (10 inch) (Also, ALL main operating functions need to have a button in addition to the touch screen) It is very important to me to be able to do config/programming ect using a keyboard (touch screen or PC) not just buttions...especially when keying text.

6) Lack of FULL style, sound and sequencer detailed editing.

7) Lack of Sampling. Should have PLENTY of sample RAM. At least 2 GB. user ram (Memory is cheap now)

8) Not having ALL sound samples in RAM or EEPROM...or whatever technology to be able to replace poor samples from the factory or just your own in some cases...with user samples. I don't want to be stuck with a poor sample with problems.

9) Lack of great MFG support AND forum support.

10) Lack of a top quality keybed. Models need to be available in 61 and 76 synth action AND 76 and 88 weighted hammer action and need to be PRO quality

11) Lack of full PC software to edit all aspects of the sounds, styles , midi data AND organzation of all data in the keyboard. Especially any user data.

12) Lack of build quality in general, want metal chassis, not all plastic

13) Lack of all arranger functions (VARS, FILLS, INTRO, ENDINGS) to be perfectly smooth with the fills working with each VAR without any glitching. (Is this too much to ask after all these years of development?)

14) Lack of a optional footpedal with at least 10 buttons to control any functions on the arranger, include also 2 continuous controlers pedals built in of top quality and smoothness.

15) Lack of the function to have a any/all sound on Upper (1,2,3)or lower (1,2) to be able to be programmed EXTERNAL with midi bank/program change to be able to directly select any user sounds on an external sound module ot soft styth just by selecting a style, performance, OTS etc. (My PA2 has this, Yamaha said I don't need it!)

16) Lack of a full function PRO quality voice processor including pitch correction, voice modeling and 4 part harmony. Or better yet...take out the cost of any VP and I'll just get a TC Helicon voice live 2.

17) Lack of the feature that has my coffee ready at any pre-programmed time...and the slot in the cabinet that holds at least 2 cold beers! :-)
