If I may just say, be careful what grease you use. I've tried several recommended greases up till now but none have worked. In fact most greases tried seized up the keys! The best lubricant used so far was pure liquid silicone, but that was absorbed into the rubber/silicone it was applied to after a very short time. I have on order, as of last night, pure silicone grease which will have the benefit of not being absorbed. I suggest you hold off regreasing the offending key until you are sure that you are applying the right thing.

Kind Regards,

Chris

p.s. the top picture a few posts back confirms that the wood is sandwiched between the keys, a solid block, not a thin laminated strip each side of a plastic key.

I've heard the numa had a polyphonic aftertouch feature and I am asking myself how this is achieved with that two wired ziczac strip. Is this some kind of capicative sensor? and how does it do polyphonic aftertouch? I mean how can it measure where the pressure comes from?
Has anybody here an idea?

I can confirm what John says Sebastian, it has MONOphonic aftertouch.

The Numa series has mono (or channel) aftertouch. I believe only the VAX77 has polyphonic aftertouch (in terms of new keyboards).

I couldn't find anything better than the Numa keybed with the combination of the "You Play" feature. I did look at several software solutions that allowed me to define a separate filter between black and white keys and assign a velocity curve accordingly...it is not worth it IMO.

I used to tune/service my real piano, and they are no better. It's the moving parts... they are always moving (and breaking)! You have the right idea though. I think we should be able to service our own keyboards more easily so we can fix/enhance them...I don't think you are wasting your time.

I have already been into my Numa to lubricate a sticking key, and I simply left the screws out because I knew I would be back in there eventually!

Yes John, I believe your right. I've made up my mind to install a midi strip. Probablt PNOscan unless anyone knows of something better?

here's the promised phot's

I believe most Fatar keybeds have this issue...hence the Numa play mode that establishes a separate velocity curve for black/white keys. It does seem to work (at least on mine). Personally, I think it was a cheap engineering trick to avoid fixing the real problem (and possibly a huge class-action law suit).

There is also an issue with aftertouch while you're in there Chris.

I have just this moment loaded up two .fxp's with the description 'mezzo hardness and volume note for note used as velocity note for note'

After adjusting hammer strike key depth, I found F4 to be kicking out a lower velocity than the any other note on the keyboard. It does nedd fine tuning globally, but F4 stuck out especially. That is why I've use it. I will post the Midi file so you can run it through the two .fxp's shortly.

I will post pics in morning Sebastian. Meanwhile, I've just done the demo midi file.

I will post them when I'm done,

Well! After playing for a while on the NUMA Nero tonight, I found... wait for it... irregular velocities!!! Thinking I would have to play it like this until I could afford to put the QRS PNOscan optical midi strip in (which incidently will fit in there fine), I was feeling a little annoyed. However, this evening I've been playing again and doing some adjustments in PianoTeq and have found a way of compensating for the irregular velocities by adjusting volume and hammer hardness note for note. This, as some of you already know, acts to some extent as a note for note velocity curve. (Here I go again!!! - Velocity Curve Chris!!!)

I will include a before and after mp3 and .fxp demos tomorrow all being well.

Lastly, I have some pics of the opened NUMA Nero if anyones interested? And when I do install the QRS PNOscan midi strip, I'll do a proper photo documentry.

Chris
