Hoi Jorick, leuke site. Ik ben ook zelf met de restoratie van een jv90 bezig en het is heel fijn om te zien dat je de moeite hebt genomen om het process vast te leggen en online te delen. Ik heb al ervaring met mijn xp-60 en die tact switches en ik heb ze via farnell besteld a 10eurcent/st. Kort geleden een jv90 gekocht en jahoor die had ook meer dan de helft van de tact switches stuk. Uiteindelijk de 64 moeten vervangen maar nu nog de aftertouch die heel erg ongevoelig is, dus binnenkort zal ik een update posten over hoe en welke aanpassingen nodig zijn om hem te fiksen (ben zelf electronics hardware ontwerper). Heb je toevallig ook het probleem van de ongevoelige aftertouch in die jv90 van jou? Hoi Hugo, ik heb inmiddels alle tact switches vervangen van de JV-90.

Alleen de volume slider geeft problemen. Ik heb hem open gemaakt en hij is echt totaal versleten. Ik heb geprobeerd via Roland een nieuwe te bestellen maar ze zijn niet meer leverbaar. Ff kijken wat ik daarmee ga doen.

Aftertouch heb ik nog niet getest maar die doet het ongetwijfeld slecht 🙂 Ik ga dat binnenkort bij m’n JD-800 proberen te fixen met een weerstandje en een potmetertje om de gevoeligheid af te regelen. Zijn die Farnell tact switches ALPS? Die ik gekocht had bij Vanallesenmeer.nl zijn volgens mij ook gewoon goedkope Chinese. Je kan ze herkennen aan het harde klik geluid dat ze maken.

Veel harder dan bij de standaard switches. Ze doen het overigens prima. Hoi Jorick, verder in het Engels voor de bredere audience 🙂 Alps seems not to produce the tactile switches anymore but other respectable brands do. Tyco (TE) for instance is a reliable high quality one. Nontonmovie33.

The performances contain 8 patches (one for the battery) as well say that to a full arrangemet the JV is quite unrealistic. No sequencer edition possible thanks to WinJV PC -> it works super full of Hell UTILIZATION Philosophy Roland regulars will feel at home. Very easy to use even with the display 2x40 characters SOUNDS.

Do you have some clue on how to solve this issue? I am a software guy with some knowledge about electronics. The board was bought brand new from eBay, I don't feel is damaged and handled it with special care.

You just have to look for the “pressure/force” spec. The Alps/panasonic switches Roland used (13169752/EVQ 213 05R) had an actuator pressure of 1.3N, so choosing a switch around that pressure 1.2N-1.5N should be fine. I ordered the original ones here (in amsterdam) but they are available at Mouser too The volume slider is indeed a challenge, but if you look at the schematics, the “presence” slider works really funny: The opamps/gain they used make a lot of hiss noise, so they gradually enable this “presence” effect only when there is sound being played. This means that the “equalizer” is noisy only whenyou are playing and you perceive this “hiss” much less.

I don’t know you but I never use the presence slider and this one is wired in parallel with the volume slider, so you can swap them, or swap the wires at CN12 (signal control), of course, in case the presence slider is not damaged too 😀. I read you have a xp-50 with a serious issue, contact me and maybe we can sort out what the problem is. Groetjes, Hugo Like. Hi Hugo, I’ve sold the XP-50 a little while ago as a ‘for parts’ unit.

But thanks for the offer 🙂 Thinking of doing the same with this JV-90. I’ve allready spend way to much time on it and the reason I bought it is that I wanted a 76 key controller because playing piano parts on 61 keys is a little difficult sometimes. I’ve picked up a JV-1000 a few weeks ago that’s waiting to be fixed (red glue issue) and I like that a lot more than the JV-90.

The JV-1000 looks very nice on the outside and this JV-90 has had a very hard life. So i’ll either fix it and sell it or don’t fix it and sell it in it’s current state 🙂 But it’s definitely going. I’ve already put about 15 euro’s worth of new parts in it and I found a new volume slider that will cost around 17 euro’s incl shipping. Maybe I can use the presence slider as a volume slider. I’ll look into that. I promised myself not to start on the JV-1000 before I fixed the JV-90 so I’m getting more and more eager to wrap it up and move on. Hi Jorick, excellent site.
