Ps - also asked yamaha about the more limited midi range so ill report back if they say anything ( though I personally think its a limitation of using the acoustic action and/or of the sensors ability to register the speed).
Absolutely! That is the only logical explanation about velocity curve, but somewhere in this forum was report about the same issues with CLP?
And also, one important fact – at "vel. 0" the MIDI sends "Aftertouch at 127" control which spoils pianos like East WestQL.
It took me a lot of effort to find it monitoring all my MIDI devices.
I had to disable "Aft.touch" on software MIDI filter to use AG as a MIDI controller when playing EWQL Pianos.
The piano (AG) is good, but not the best because it has a number of details that have not been decided to make the piano working also as an external MIDI keyboard controller.
For retail EU price ca. €6450 this instrument had to offer more versatile control over the signal input/output, adequate but not sounding cheep reverb, MIDI key. vel.-curves and so on, to support USB audio AIFF or WAV or MP3 (play/import/export) format and many other options, that are found on such instruments as Kawai and Rolland, even that they sound compressed and emitting unrealistically tang sound (pop or rock alike) at high velocity.
As many of us that picked up AG, I chose it mainly for the keyboard action and sound (for composing and teaching my 6 y.o. son).
In addition about its own (AG N1) sound system: when I compare the sound to the same signal going to studio monitors (in my case Genelec) – N1 sounds nice, piano like and of course "woody", in positive sense.
However, playing much louder than normal piano does, there are specific resonant zones between 350-800 Hz due to the body on AG N1, which over exaggerates "piano acoustic".
Talking from my short (only 2 months) experience, this AG N1 sounds better when internal speakers and external Genelec monitors are switched together in parallel (at "12 o'clock" or on 50% volume control knob AG N1 to more than 50%-60% Genelec).
It fils the studio very nice with added reverb form Altiverb ("Shubert hall").
For sake of that treat, as many other colleagues, I also would suggest you to take one external sound card and to control the output of your laptop.
Mac or PC – it does not really matter, because the sound is being reproduced by the external device.
Just as an budget example:
In EU is about € 250 and one of the most important option on it is the build in MIDI interface.
Thus you will not need to struggle with pulse noise, high "Pegel", full of issues "MIDI to USB" interfaces such as "M-audio MIDI spot" or ~3 times more expensive (ca. €63) but working very well "Yamaha UX16 MIDI Interface".
Just a pare of (DIN) MIDI cables – they are much cheeper than both mentioned above.
IMHO, on the ground of more than 6000 (EUR/USD) man pay for AG N1 it is as a kind of "must have" accessory.
I wish you success finding the best solution for you.
