Hi Guys
At the moment, how much can it cost more or less? it is difficult to find one in good conditions
Is it still worth it, or Nowdays Emulator Munt is on par?
thanks

If you can get an MT-32 for a good price, then go for it. Nothing beats the original hardware.

However, considering the current prices, MUNT is your best option. Phil (Philscomputerlab) made a video about it some time ago. The most expensive component you will need to buy will probably be the Roland UM-ONE MK2 USB MIDI Interface. The rest are free and/or you probably already have lying around.

Old hardware is always fun, although I'm not aware of a significant technical reason to prefer it. In general, Munt is now extremely accurate, although the legality of the ROM files is a grey area. You can check with sergm if you have questions about specific hardware versions, their bugs or quirks, and what stage Munt is at in replicating them.

I was going to suggest the Roland RA-50 as a mostly MT-32 (newer version) compatible, but their prices have shot up in the last 2 weeks . They are still cheaper than an MT-32, though . They need a relatively simply hardware mod for full MT-32 compatibility (or you can use Softmpu or a Hardmpu).

Which Would be in your opinion a good price? consider Shopping cost for Europe..I live in EU..
It makes sense to connect ti a modern pc?

A good way to have an idea of the going rate is to look at completed auctions where the item actually sold (though there are probably some fake results in there where the seller and buyer are the same person and trying to inflate apparent market value).

Connecting to an MT-32 to a modern PC for use in DOSBOX makes sense to me . For years I used mine like that (before I got a retro machine).

I have an old MT-32, and recently plugged in everything. IMMEDIATE LOUD STATIC NOISE unaffected by the volume knob. I tried other sources and normal audio from the speakers. I tried other adapters to rule out the 1/4-1/8 converter, but the noise persists. I started to recap the board, but it is very time-consuming, and my skillset is not the greatest. Any ideas what components to look at?

Hi, I have got an old MT-32, too, but not the same issue.
Can you please, if possible, attach a sample recording of a few seconds?
Maybe this helps us a bit, not sure. 🙁

Generally speaking, the power supply can also be the cause.
The original power brick was a transformer-based, for example.
So far, I've never tried a switching PSU with my MT-32.
Please double check polarity. A ferrite clip can also be used to get rid of coating waves.

Sorry for my poor English, haven't slept enough.😴

Edit: It wouldn't hurt to check the the voltage regulator also (7805 series?).
On the other hand, if it was broken safely, the MT-32 should be silent.
Anyway, no need to panic. These are just some random thoughts of mine.
On vogons, there are many MT-32 fans around. I'm confident they can help.

I started out with emulation first, but afterwards I just bought an MT-32 because I really like the way it looks. Especially seeing that green LED makes me a happy PC user. And the occasional funny message that gets projected on the LCD by certain games is also worth it to me. That's something you don't have with an emulator.

Here are the specs on the ps I have:

Roland MT-32 multi timbre sound module
These aftermarket power supplies are new in box and have never been used. Center negative pin as required by these products. Do not use positive center pin power supplies with these units! It will damage them.

Specifications:
I/P AC:100V~240VAC
50-60Hz
O/P DC:9V DC 1A
Cord: 36in
Tip: (-)center, (+)outer

I can say that when I occasionally in the last 20 years have used the wrong polarity with the MT-32, it loads, but has loud static. So the PS is probably the issue if it is the wrong polarity. Do you have another from a synth or other equipment to test?
