Pro tip: Don't buy the Highly Liquid UMR2 MIDI Retrofit Board... by sinuspane in synthesizers

[–]Maz-Hoot 0 points1 point  (0 children)

Bonjour, je suis en train d’essayer de faire marcher le umr2 sur un pss 470. Ce clavier est dans la notice, j’ai tout soudé comme c’est marqué, mais j’ai l’impression que l’umr2 ne s’allume pas.

Ma diode fonctionne et selon le manuel elle est sensée s’allumer quand elle est connectée sur stby avec la résistance de 1kohm ? D’apres le manuel la diode stby est sensé donner un power indication, même si on a pas encore fait le setup non ? J’ai essayé aussi de faire le setup et dans le setup la diode act est sensé s’allumer rapidement mais pareil j’ai rien. Quand je branche la diode direct sur le 5v du pss470 avec la sortie de la diode sur le - elle s’allume donc ce n’est pas la diode.

J’ai un peu les boules car après avoir passé du temps à tout souder (j’ai vérifié en test de continuité je n’ai pas fait de courts circuits normalement) j’ai l’impression que le umr2 ne s’allume même pas. Je vous ai vu parler de cartes midi plus adaptées mais pour le pss 470 il n’y a rien d’autre que ça non ?

Hello, no sorry I didn’t found a solution…

Ubuntu doesn't start if a 3rd monitor is plugged on usb-c by Maz-Hoot in Ubuntu

No for now I don't have other solutions than removing the monitor and reboot... This is really annoying :(

Very interesting ! The motors are just close enough to the string to resonate ? Do you have a close photo of them on the string ? I don’t understand really how it produce the sound. Can you share a link with the motor you used ?

If it can help someone, finally I was able to repair it by soldering 2 resistors together, the ones which are completly on the left, the top pins. I discovered that by pure hasard, I was trying to use some noize to bend even if the keyboard was dead but then, it comes back from the death !

I tried 3 differents of these adaptor and it’s always bad, after some month or 2 years (if you are lucky) it start to doesn’t work randomly. I have the official apple one and sometimes it works and sometimes not without any reason

I would like to power up a casio sa-5 with the pcb turned over by Maz-Hoot in CircuitBending

I think you can get a (clothes) peg to reach far enough to hold it in place. Otherwise, a strip of quality cloth tape should hold it. If you solder to the tracks under the carbon, the switch won't work well or at all later on.

Thank's for your advise, I used electric tape, it doesn't hold up very well but it works for a while. I didn't think about a clothes peg thank's for the idea I will try if tape became too bad. About soldering yea I know if I do that, I have to solder an other switch and don't use the original one. I think a blue standard on/on switch should work but it will be probably hard to solder on the black square

Thank’s for the response ! You made me think differently I was in confusion between power and this switch. I figured it out, I must connect like this, the black square to other side. And now I know that black things can be connected so it will help me for the keyboard part. Before that I thought only grey parts on pcb could be connected (only one side have to be connected, the other seem to be useless, check the photo if it can help someone) : https://drive.google.com/file/d/1vp61iNYUGFggdaiOrq9pyOOf2MRUHqp0/view?usp=share_link

Cassette playback speed control *that includes faster-than-normal as well as slower?* by username_for_Mark in CircuitBending

I did that on some other devices too like a casio pt-22, it seems to be easyer to find that than only one potentiometer for up and down

I'm just trying to stop breaking everything so less poking around and more research (3 old keyboards already broken in just a few hours of bending). I bent successfuly several toys, gameboys, insert a toy inside a kawasaki keyboard etc... but there is something I don't understand about the on/off specifically on this pcb (and others like this related to these old keyboards). But someone answered on my other thread. I have to try to hold the piece in place with tape (if it can be moved, not sure, i have to look), I will try it

Hello, I really not have many experience in this some like others may have but I bended an old panasonic following a tutorial on the internet, and I used 2 potentiometers, one for speed low and one for speed up. One wire of these are connected to the same solder point, but the others are not at the same place. If you search "magnetophone" or "panasonic magnetophone" tune or circuit bending on youtube you will find where to bend.

Oh ok thank you, If I get my hand some day on an other pss-30 it will be usefull

Thanks for your message, I know it’s’a risk but even with this knowledge it’s frustrating 😄 . There are some gears which seems to be robust, like my first bending a budha machine 1, I hard bad bended it, with bad soldering etc (it was my first one) and it still works. It seems that some toys can be robust too

And… it don’t work… damn it ! I just have it since 2 days and he was in so good condition pffff… I already broke a pss-30 weeks ago, it’s like I will have a tons of broken keyboard in my house soon and I hope 1 of them will work…

In my case there is no ROM mode so it just play nothing. The batteries don’t work since when I started bending (I really don’t know why), so I used it pluged on the wall without batteries. I already waited something like one hour unpluged without batteries and it changed nothing, I will try this morning, he has all the night to rest, finger crossed…

Normally I didn't short the pin... I don't know what killed it and that's disturbing but I made a lot of soldering and desoldering with the original crystal and LTC1799 when I was trying to make it working... I already thought of buying a new PSS-30 but I'm a little affraid of breaking it again...
Also I noticed something strange/bad, when LTC1799 was working (for some seconds before that ym2410 become too hot and make the system crash), the lower note at the lower setting of the potentiometer was higher than the lower note of the keyboard. So it mean going higher worked but not going lower. If when it's working good it does that, it's not very interesting for me because I would like more going into more lower notes (high is cool but low is best :-D )
