Midi Keyboard Velocity Test

Well, AD means analogue to digital. I can't see anything basically analogue in a keybed scanner electronics - there isn't - it's pure digital from the beginning, just a pair of switches.
Analogue in general sense points to something continuous, not necessarily voltage. But even if you think of metered timing (that's what it usually ends up to be) there isn't anything analogue too, it's all happening in the digital domain. Just the pots, faders, wheels and things like that need AD. Even here there are alternatives with digital encoders - and before you ask, there aren't just incremental encoders, there are such encoding absolute values too, even if these are preferably used in industrial applications.
Finally for organs one does not need velocity at all... That's indeed not the #1 choice to make velocity accuracy a topic.

Thank you TiUser for these useful reminders
Incidentally: around 1975 , I designed the first marketed guitar synthesizer (Digitone ORS GM 201). It used a (patented) digital "period-meter" to encode and memorize the period of (analog) guitar signals...

This game seems quite useless, but rather funny, there you go, the results from brand new Alesis Q49, pretty cheap keyboard.
I'm pretty sure I can't hit any more whites, I have been trying long enough. Middle range filled up quickly, low range I had to try to shoot down, remaining blanks are invincible and seem to form a pattern.

I agree, the basic test pushing any keys for a while is pretty useless. It just shows some extreme allover problems. It doesn't show anything about response of each key - unless you hit all keys individually. It also does tell nothing about repetition accuracy of individual keys.

Here's my Akai MPK61 after a few minutes of messing around. It's pretty easy in the beginning but as the gaps get fewer and fewer, it requires more patience and precision to fill them in.
I was later able to fill in the gaps by experimenting with the various velocity curves like Log and Exp, but I don't think any one curve makes all values available. Linear gets close though as you can see in the picture.

Thank you, remure!
Hey folks, check your controllers and post you results!

My E-MU Xboard 25, Velocity curve 1 (linear), MIDI Minimum Velocity 1.
I'm impressed I was able to get all the notes. Took a while of playing on different keys to get them.

Interesting tool you got there. Just don't use it with the old DX7 as a controller. 0-127 wasn't standard back then but only 1-100
I have to try this on my Kurzweil PC3x too though - it shouldn't have a problem nailing this test

i changed the VCurve to Linear and it was easier to cover the lower range

It doesn't matter how it sounds..

Here is a Casio Privia 320, 3 years old, test. I could hit all them with some patience. Appear to be that treble notes are configured in a diffrent way than the bass ones, at least is more easy to hit certain velocityes with ones or others.
