I've been playing (gigs, with a jazz group) with my old Roland RD-700 which dates to 2001. It has 64 megabytes of sample storage (yes that's MEGAbytes). Nothing by today's standards. It's keyboard is awesome and has held up well for 20 years. Nicer I have to say than my new Arturia Keylab 88 MKII. The Roland was a top-flight board in its day. It does not have USB (midi or audio).

I'm playing it now through a 7th gen iPad running Pianoteq, using 5 pin midi, and it sounds awesome. The iPad interface is far easier to deal with than the board's hardware interface. I'd say its main limitation for me is that it (the board) only supports on/off sustain pedal, it doesn't support half-pedaling. But in a gig that's hardly ever going to matter. I sold the two sound expansion boards I had long ago purchased for a good price on ebay--about as much as I paid for them originally. I don't need them anymore.

My son stored his CP88 at college when he came home for the summer. While here, he's using my old 90's era Alesis QS8, which has a fairly well regarded Fatar TP-20 action. It also has 5-pin DIN MIDI but no USB. Are you using a normal audio interface to get MIDI to your iPad, or a MIDI to USB converter of some kind?

I've read good things about the $60 CME WIDI Master, namely that the latency is actually low enough to be usable. CME also makes a $20 5-pin DIN MIDI to USB MIDI cable, the U2MIDI Pro, which builds the conversion chips into the USB-A plug at the end of the cable. Might have him get that if he doesn't want to risk using Bluetooth MIDI. I'd like to hear the experience of anyone who's used any of CME's MIDI products (we have an Key Air 37 which has been flawless with Bluetooth MIDI).

My faithful Kurzweil K2500 dates back from 1996, I continue using it almost every single day of my life with Pianoteq. Please enter my post for the "dinosaur" contest !

oh waw indeed and you don't think more digital pianos would have a better action etc? new ones have double escapement but i read that it has no effect in playing.so ..

HI i am asking  because some like me may not want to upgarde their digital piano... the sound is not as good as pianoteq (it is based on 2001 samples so...) I connected it to my computer with pianoteq in it.
I do love it and tested the required weight to make the key go down : between 60 and 80g exactly like a real one... I played too a real one when i was young.
I also have a marantz amplifier and cabasse mt 32 tower speaker very good and expressive...
other people do like me an old digial with pianoteq?
thx

Yes using digital pianos midi/MIDI USB out is common.

Pianoteq is night and day better than the short (and thin sounding) samples built into my Casio CDP.
That said Pianoteq is better than any built in sounds I've heard so far from hardware, though i am sure there are many of pleasant sounding virtual pianos built in to the top digital pianos.

Most hardware pianos only have a handful of velocity layers, short samples and obviously no real potential for adjusting those sounds.
Combine that with small cheap drive units built into the plastic frames of digital pianos.

Pianoteq is a no brainer for old and new digitals alike.
If you wanted to find a piano collection to compete with Pianoteq (on sound quality grounds) you would have to start looking at hundreds of gigabytes, or even start looking at eating whole terabyte drives!!!
