Midivox III Help Needed

[TonyChicago]

Hi,

One of my accordions is an Excelsior Midivox 3. I'm trying to get my boxes all back up and in shape and there's no way I can find then power supply and cable. What are my options? I know there's a power supply on eBay, but it may be for a Midivox II as it's not showing the III on the front. Would that supply work do you think?

Thanks

it is basically a 5 volt power supply, with the breakouts for volume pedal etc.

i suppose it would work.. you also may be able to order one from Pigini/Excelsior

Thanks. The one on eBay shows 117v and 9 watt so it isn't showing the actual voltage stepped down. What about the cable? It looks like a female to female threaded 8 pin connector would work, but I'm concerned it may have proprietary wiring. So I can't seem to find one online for sale.

Sucks I misplaced it. I have the swell and foot pedals though.

Thanks again.

yes, the ground needs to be on the correct pin and the mic audio
wire is shielded .. it may take a few days to find it but i have the cable schematic

Thank you. I wrote Excelsior in Italy so I will see what they say. But like I said, there's a guy on eBay selling one that I might buy in the morning. He sent me a private offer.

check with Scotland accordions….they advertise them…also Accordeons excellence in Montreal…they modified my midi vox 11 power supply so it powers my midi vox 111 accordion…..if you get stuck, I have one ready to go.

Thanks for that post.

Excelsior was a bust. They could not offer me any support. I also did contact midirig in the UK. They were shockingly expensive. I will try the place in Montreal today and see what goes. There is one for sale on eBay (from the UK) and I'm watching that and hopefully can win it. It has another few days to go before the auction ends.

Try Scotland Accordions, they manufacture a power supply for this accordion.

Yes, I did contact them. Waiting for a response. I know they want about $240 USD just for the power supply. Then add in the cable and shipping.

778 Kilobytes JPG image was rejected as too big

(778Kb.. i kid you not)

so i guess i will have to email you the schematic for the power supply

I'll PM you

Edit: Can't seem to do it

ok i scanned it smaller

i own and gigged for decades with MIDIVOX II
first was the 960 i got at CEMEX and later a 911 i picked up as a spare

the 960 is unison jazz LMMMH
the 910 is very French tuned LMMM

i also built a power supply as a spare from this schematic, and made a spare cable
which it is easier to do if you breakout the Mic connections to a separate jack on the grill
and then you have a much simpler firing cable to make

i also upgraded the panasonic OEM Mics to sennheiser rails but still
powered them from the MIDIVOX brick

i do not know what differences there are to the MIDIVOX III

 

[Ventura]

also dissapointed to hear PIGINI offered no help..
noticed on the Excelsior site they do not offer a MIDI model anymore
at all

couldn't find a link to Marco either (the young fella they kept from CEMEX
that ran the electronics division)

Thanks for the schematic. The guys in the UK want $399 USD with cable. Midirig told me there is a difference between II and III but didn't specify.

Sounds like you had a nice setup. I like that you separated the mics. I did not know that Panny mics came with this. Although I actually have a different accordion than you. Mine is actually called AVD 3. Two low reeds and a middle and extended to high C 44 keys. I bought it from John Castiglione. It was made for someone quite famous but he passed on it once he tried it because it weighs a ton, so I was told by John.

I'll see how it plays out on eBay. The bidding ends on Monday. If that falls through I'll just let it go for now and keep an eye out for one eventually.

Here's what I received:

thank you for your email.



With reference to your request we regret to inform you that spare parts for Excelsior Midi accordions are no longer available, since we have stopped producing Midi accordions many years ago.

We can only suggest you to check if someone is selling these spare parts on Internet as for example EBay etc.



We are very sorry for not being able to help you.



Best regards,



Donatella Melella

A question here…. I apply 5 volts + to midi pin 4, - minus to pin 2, what is pin 5 from the midi socket. I don’t need volume/ swell, I don’t need acoustic pickup… I just want to send note on off to a midi socket. I will install the socket on the accordion, power with 5 volts, insert Widi in midi out, andI have wireless midi. My Ketron unit has swell for the right hand midi sounds. Will that work? All I want from my accordion is note on, note off to the arranger.

Hey Tony,

Just to confirm for most MIDI setups.

O….. Pin 1 (No Connection)
O……… Pin 4 (+5V DC Voltage)
O………… Pin 2 (Ground/Common)
O……… Pin 5 (MIDI Data – Hot)
O….. Pin 3 (No Connection)

Now... to answer your question.. in theory it SHOULD work. The MIDI is the "on-off" switch of the MIDI and the additional info of the swell volume control data of the KETRON SOUNDS ONLY should be controlled by the swell pedal of the Ketron. If you are doing it with the cable, it should do 100% the same with the wireless MIDI transceivers.

All that said, depending on what MIDI transceivers you are using and how heavy the MIDI bandwidth is in relation to what the wireless MIDI does... you may get little to no latency... or you could get latency that is in the "several seconds long" range.

In my setup, I never used wireless MIDI and external modules for the right hand, I use it to trigger the proper chords and to send data from SongBook to accordion... both are transactions that are very singular and short. Asking it to do complex and fast changing 5 finger chords might be outside it's capabilities. Only your testing will answer that one.

Thanks on that Jerry, I have been using WIDI successfully for left side on my lmmm Hohner. The one I installed midi on …..The accordion.you checked out for me..I tuned it , installed the home made midi on the bass, and it works great.
Also have used it on a conversion I did ( for experiment ). On a 72 bass accordion. Both left and right hands….Also for a friends FR-3X. To control a Ketron
arranger. I have had absolutely no issues with “ latency” If, I can figure how to power my 940 midi system, then it will be wireless also.

You were wise to pick it up that baby, I had my eyes on it... lol

The MIDI bandwidth is something that is actually quite limited. Even on accordions like a Roland FR-8X, by me sending higher levels of data sent into an arranger (for example, bellows volume at highest data resolution levels), will send most wired setups to their knees and cause arrangers like a BK-7M or X8 to freak out and fail or lose connectivity... wireless setups will feel the pain a bit sooner... lol

Since Tony wants to send his right AND left hands to the arranger, I have to add that caveat in there, so that in case he does experience it, he will know what it is.
