So Cloud, while I think of it, were you calling the CM-500 a 3rd gen MT-32 device, given it has the sound quality improvements of the 2nd gen, plus some quirks? Or am I getting confused here?
Cloudschatze wrote on 2023-01-10, 03:33:Separate from the LFO/vibrato issue, I am currently troubleshooting yet another errant CM-500 behavior, this time related to the MIDI switching/handling function of the Mitsubishi 7702 MCU. If anyone happens to have a CM-500 with a serial number greater than ZE13000 (with corresponding "CM-500 1.02" ROM @ IC22), can you please get in touch with me?
Not that it matters or will help, but my serial number, which is ZD83743, decodes as being unit # 3,743 from May of 1992 (1.00 IC22 ROM), so you really seem to want someone with a serial number after ZE13743. Of course, this is not a real concern as the release date must be from August of 1992 or later (and having the IC22 1.02 ROM), but I found it interesting that I have a unit number greater than your requested unit with an earlier release.
That silliness aside, I'm probably about to be disillusioned with another unit that won't help you, but we'll see when it arrives. It's got the serial number of ZE80482, which I decode as unit # 482 (lower probably due to the model number change from dm-500n to dm-500n-3) from March of 1993.
I probably should have consulted you before making this frivolous purchase, as it probably doesn't have that 1.02 IC22 ROM version, and you might already be aware of it. But, anyway, it will give me a chance to compare its, hopefully true, General MIDI support to mine's falsely labeled General MIDI support (which has the Sine Wave variation 8 at PC#81, yet not Breath Noise at variation 0 of PC#122 which should have displaced Fl. Key Click to variation 1 for GM support).

The last four digits of the serial number seem to loop based on some predetermined counter, and are probably only meaningful concerning production comparisons within the same month or year.
In other words:
ZD83743 < ZE13000 < ZE80482
Unless it was swapped for reasons unknown, the ZE80482 model you just purchased should have CM-500 ROM 1.02. I'd made a few offers on that same unit; alas, the seller wanted more for it than I thought its condition could justify... 😀

I tested all of my CM-500 and CM-300 units after reading your initial account of this, including both earlier and later variants of each (that is, inclusive of those bearing the RLP-3037 and RLP-3170 GS daughterboards, respectively), and was unable to duplicate the behavior. They all produced Breath Noise at CC0 #0, PC #122, and Fl. Key Click at CC0 #1, PC #122. Is the behavior you'd experienced consistently reproducible with your unit?

This is a link to the file that I use to decode serial numbers from 1989 and later: http://llamamusic.com/super-jx/Roland_Serial_ … r_1989-2010.pdf.
It's why I favor the model name change reasoning instead of wraparounds, but yes, it could be something like that.
And yes, the condition looks pretty bad, but I'm more interested in trying to solve mysteries than aesthetics. It's possible that it came down in price after being sold in Japan, because after I bought it I searched for "dm-500n-3" and all that came up on google was a more expensive listing of the same unit from a different seller (https://www.ebay.com/itm/404137981802). The other possibility is, I'm being scammed and what I'm being sent is a different unit than pictured, although they are obviously other pictures of the same unit. It's still pricey, but here's the one I bought: https://www.ebay.com/itm/354609719230

Well I feel sheepish. Your suspicion made me check it just now, and sure enough, I do have Breath Noise at variation 0, and Fl. Key Click at variation 1! I was testing using my qmidiroute patch before, too, so I don't know what changed (or more likely, what mistake I was making). Mine contains the RLP-3037, by the way, and is blowing sweet breath sounds at me presently. 😀
Thanks for making me test it again, but that will mean my new unit will only be worse than what I already have! 😉 And that really is fine if we can figure out whatever you think is wrong with version 1.02.

This is the best outcome. 😀

It's just the opposite, rather. There's an occasional behavior that I'm experiencing in Mode A with my v1.00 units that is presumably resolved with ROM version 1.02 (based on some vague information I'd received from Roland Japan a couple of decades ago). When you receive your ZE80482 unit, can you please send me a PM for some further discussion? 😀

I agree! 😀

Definitely, and that's good news, although I haven't had a use for mode A yet (just B & C). I'm glad you haven't forgotten vague details from decades ago!
I noticed an INTEGRA-7 freezing issue and was only able to communicate through an english translator with Roland Japan, so the final verdict wasn't too satisfying:

They are saying that this issue is mostly being caused by using the SuperNatural drum kit in the Integra-7. If the maximum polyphony of the SuperNatural drum kit is exceeded, this can cause processing errors, and also the SuperNatural engine apparently uses a lot more processing power than the PCM engine (which is why an older Sound Canvas could play a file like this with no issues since it only uses PCM).
They also said that some DAWs appear to organize the event order differently, so they did not see this issue when using Cubase, Studio One, or Logic.
It appears this is not a bug, but just an overload of processing power in the module, so they had the following suggestions:
- Use a PCM drum kit instead of a SuperNatural drum kit.
- Use a different DAW if possible.
- Filter out the CC#10 pan messages. There are a lot of these and if they are filtered it helps with the processing also.
I would have thought a firmware update could be developed that lightens the load by filtering messages (or buffering and rearranging them). However, I can also imagine musicians would want the INTEGRA-7 to always follow their own exact programming, but this freezing was a bit unreliable to begin with (it took repeated playbacks sometimes). Perhaps they're still working on it, but it has been a couple years since I received that response. Still, I suppose this is all interesting. 😀

That was the fastest shipping I've had from Japan (three days to Wisconsin, as they waited until Wednesday to send it)! Anyway, PM sent, but I'm not sure its ICC22 is version 1.02. I'm hoping your reply will say it is.
