Found in a flea market a Sk-5 with instruction manual and box. For 30 euro I bought it. At first looed as a lemon because with batteries it didn't turn on. But after some wiggling in the external power connector it started working. I suppose that I have to open it and check the solder joints, or use some contact cleaner to the power connector. Also it smells burnt, and maube it's because the former owner was a smoker or there's something inside that had problems, like tantalium capacitors. Now I have three Casio keyboards in the house (and a calculator,and two watches)

Old school analog FM headphone like this https://www.p4c.philips.com/files/s/sbchc8440_00/sbchc8440_00_pss_.pdf have a low latency because they dont process the signal. On the other hand it's plain old FM stereo radio, with all the distortions we radio listeners love.

Not having a schematic diagram it's a problem to find where the problem is. Now whe the firmware it's botched, from what I've read the backlight still lit ups. So if you see a completly dark mainboard, and there's a switching regulator for the 5V rail, and the backlight it's 5V, it could be a capacitor in the power supply.

Maybe you coan try to use a passive DI box and get a transfomer-insulated output. @Jokeyman123 I remember that in hi-fi circle swapping op-amp was a thing. Now it's true that there were Philips-branded and Marantz-branded CD players that were very similar, had the same circuit board but some of the circuitry was different, and the Martants ones were sold at a premium. You could desolder components from the Philips, put the components used in the Marantz and get the better performance, but I duppose was more cost-effective buy directly a Marantz.

I think it depends on the price. I paid mine 670 euro in 2018 and now the price I see online is 970 euro. For the 2018 price it's a good buy I think, for 2023 price, I'm not so sure.

I suppose that the MZ-X 500 uses custom ASIC and mask-programmed microcontrollers, so a chip shortage it's possible on one of these custom parts, and no chip foundry could make them in reasonable time due the technology of manufacturing. Maybe the older keyboard are using different IC that could still manufactured from some foundry. Worse they have used a no longer manufactured standard part. And if this happens and a redesign of the circuit has to be made it's a problem.

I see that in most of online shops in Italy the PX-5S isn't available. Maybe the successor of it is arriving? Wild wild guesses.....

Have an iPad 2 that is used basically only for that. On newer IPads there's the paid MIDI designer PRO2. Maybe it's backward compatible with the XW control?

Maybe it's an old school headphone with a switch to exclude the analog audio. There are jack switches with extra contacts that can work with two jacks in parallel.

I have an XW-G1 that has 9,6 V input, and the wall adapter doesn't have a ground pin. The small leakage current maybe it's due to the parasitic capacicance between primary and secondary windings of the switching transformer.

This is because I have the bookmark on the unread content. So I missed the thing on home page.

I've found an annoying "upgrade". Now isn't possible to log in using simply the username, but the form forces you to use the email address for logging in. Interestingly, if the browser was already logged in before, the old username is still working, and from what I've seen in the behaviour, there's someting client side that checks the username format and forbids the logon process if the username doesn't look like an email adderss

Proel makes PA system and loudspeaker, solid state amplifiers, microphones for stage. Dexibell it's the keyboard brand, and they make some stage piano and clonewheels in the price range of Clavia Nord products. Ad a music group they have also a guitar brand and a drum brand. Roland was in Italy because in the 80s bought the SIEL factory and their IP and patents.

Roland used Fatar keyboards because they made production in Italy. https://goo.gl/maps/iYSxezY219yiWEpH7 Now it's Proel and Dexibell, but if you go back in street view history you find that was indeed Roland. Nearby there's still the Roland plotter factory. https://goo.gl/maps/bzHFZPTxhmbK6dK38 Fatar facory is 70 km north, so makes sense that Roland used Fatar keybeds, as Dexibell does now. Viscount uses Fatar keybeds for hammer action keyboard, but designs it own for organs, both digital and pipe organs.

I agree it's a nice product. The speech synthesis is an interesting feature. For the sampler I have the XW-G1 🙂 and anyway I don't have the space for another keyboard so I think I will pass... A funny note: I was seeking videos about the little brother CT-S500. I was baffled because I found a lot ob road bike videos. CT-S500 it's also a Shimano product.
