Your welcome,
Thanks.
Well, it is still "essential" isn't it?
What's not essential?
One can argue that Velocity and Sustain/ Hold pedal is'nt essential. Some actually does'n t need more, as they disconnect it anyway in the way they work.
I can imagine Arturias thinking is, that many would like to play piano, and then they have added velocity and the most simple on/ off pedal option.
But i'm sure many piano players in example would like Sustain, Soft pedal and Sostenutu pedal and find that and half pedaling essential.
Many Organ players would find at least a pedal to control Volume to be essential, and perhaps also pedal inputs to control different types of Leslie controls.
One that like to play a CS-80 and alike will in example say that polyphonic Aftertouch, Mod Strip and different kind of pedal inputs are essential.
Some would say some X/Y pads, Joysticks or both is essential.
Some will say a breath control input is essential.
Some would say a third wheel is essential.
Others would say CV control is essential.
Some will say it's essential to use footcontrols too change presets in a playlist and so on...
So a controller with at least 8 controller inputs with variable functionality, at least 2 X/Y pads Joysticks or both, 3 wheels, Channel and Poly Aftertouch, a Mod Strip, CV control options and a very good and well responding velocity and aftertouch should be essential to cover it all. I actually would like a controller with it all - perhaps except CV as i don't use that now, but perhaps i suddenlu need it and find it essential.
Some might even think MPE is essential, and actually for some things can't argue against it. I might even need it my self sometimes.
And off coarse a multipage midi CC system is essential, with at least 9 faders, 9 knobs, and 2x9 buttons per page, and a knob that can function on any parameter the mouse hoover over is essential.
As you can see - the point is that anything is essential, but it depend.
