Don't hold your breath, newer decks are going to get updated long before legacy hardware does.

Your best bet is to not upgrade anytime in the next 6 months. Honestly with so many OS'es still getting security and other updates from Apple (Sierra and newer) there is -no- reason to upgrade as is on a production/live machine.

"legacy gear"? - How is the Rane MP2015 considered legacy gear? Reason I ask is that it's a current product. >>> dj.rane.com

SL4 is in the same boat, it's been many years since the last firmware/software update for them. The -only- thing in the past 2 years Rane has release is the 72 and TWELVES but hey, OP should be asking Rane vs opining here and just read any one of their many posts they have made leading up to Catalina about their hardware:

dj.rane.com

But just like people complaining about the newest Win10 versions breaking many things - DJs should wait before touching Catalina on their main setup.

I can't write authoritatively about the MP2015 as I only wish I owned one. However, I do own an SL4 and despite there being a Preferences Error which reads: "There was an error in SL 4 Audio Control Panel preferences." on Catalina I installed on a sacrificial laptop, it seems to function with Serato DJ Pro 2.2.3 without any other issues I can report at the moment. I have even tested the SL4 with software Serato definitely does not support and it still sounds and functions A OK on Catalina despite the Preferences Error.

(for those reading who may care, my DS1 also seems to function OK on Catalina, though it never had a System Preferences app icon and still does not)

Presumably Serato developers will iron that out any MP2015 and SL4 issues with an official release and Catalina support soon enough?

I can confirm that MP2015 isn't working on Catalina yet with a fresh install. lol

Mine arrived two days ago and I have a laptop running Catalina, so I'm sort of screwed until the driver is updated I guess.

My DB4 worked fine however. I might have to switch back until the MP2015 is supported officially. Bummer.

I bit the bullet on a backup laptop and upgraded to Catalina from Mojave. Latest version of Rane Control Panel and MP2015 Firmware had been previously installed.

First thing I did was plug in the MP2015 and boot the Control Panel, Serato and Ableton. Everything seems to be working fine, been sending signal and mixing for 20 min. Shows up as an I/O in Ableton and OS system prefs.

Not the best test I admit; will update after extended testing soon. It hopefully could be that their driver/RCP installer is the culprit in which case a fresh install of Mojave, followed by the Rane Driver, then an upgrade to Catalina would work for laptops a year old and earlier

Wouldnt suggest this for a game-time gig though just yet

Still working OK for you?

I'm surprised that they still aren't officially supporting Catalina for the MP2015 (and wondering what problems there might be!?)

Yeah, no problems on Catalina. I think the issue has to do with the installer, not the driver, as many apps had fresh install issues with Catalina until developers sorted them out. Although I haven't tried a fresh install of the Rane Control Panel (I upgraded from Mojave on the Catalina laptop), anyone running into issues should check this out:

support.apple.com

My main performance laptop is still on Mojave by the way, don't see a need to upgrade right now really unless I have to get a new computer.

We unfortunately had to give up on Rane all together. The lack of timely info, responses, customer and product support, etc. has become too much to deal with anymore, so we sold all of our Rane gear and moved onto other manufacturers who are listening. It’s a shame what has become of what was once such a great company all these years after they were acquired by InMusic. This was sadly predicted too back when the acquisition happened.

Who is this "we"? I have never sold single Rane device from day one including my SL1. Furthermore this is not in ANY way how it should have gone. InMusic does not assume responsibility for any of Past Rane's hardware. How could they. If this were the way no company would ever be able to sell ever and would be forced to fold. It was predicted because it is common sense. If anything it would have been a huge shock and bonus if they HAD decided to support any Legacy (and trust it is as legacy as it gets now) hardware.

We as in several of us who owned the MP2015.

Regarding “legacy”; Again, as previously stated, don’t know how anyone could consider a product that is CURRENTLY produced AND sold as legacy >>> www.rane.com

Who is producing it? It was made my Rane who no longer exists anymore. InMusicm may be selling off old stock (which there was plenty of) but I would say any device that is no longer being actively supported or developer for is as Legacy as it gets. How have the updates and patches been for this device?

Rane does currently exist. InMusic purchased Rane nearly five years Rane, who is owned InMusic has been manufacturing, advertising, and selling the MP2015 ever since it was acquired by InMusic and still does today. The MP2015 is currently listed as a currently available mixer on Rane's website and countless dealers' website, and is not listed as a discontinued item (which would be 'legacy'). If Rane, who has been owned by InMUsic for nearly five years now, is currently selling customers brand new MP2015 units, then it is expected that those units would be supported by the very company who makes, advertises, and sells them, especially when you consider these even come with a manufacturer-backed warranty. If Rane, which is owned by InMusic, isn't going to support the very product they currently sell, then they shouldn't be advertising that they do and selling it to customers under false info. Don't know how anyone could possibly not understand this, which is why there are so many frustrated MP2015 owners since they've been waiting for firmware updates for about a year and a half now for MP2015's control panel to function on macOS Catalina, and now Big Sur.

PS: Believe the confusion for some on this is Rane's current usage of the term 'legacy' on their MP2015 webpage. The term 'legacy' here is in reference to the 'experience' of 'mixing' on a mixer (the MP2015) which is "Born from a legacy of rotary club mixers". This is not the same 'legacy' as in a discontinued product that is no longer supported because if it was the MP2015 would clearly be listed in the 'legacy' section of Rane's website and not currently for sale on the page for the MP2015.

>>> Currently available MP2015 on Rane's website: www.rane.com

>>> Legacy products on Rane's website (note MP2015 isn't listed here): www.rane.com

All I have to say is welcome to InMusic. This is nothing that wasn't expected though. I heard they will support them (limited) hardware wise but if I am not mistaken they can't be bothered to support on the SW end and if I am further correct I heard this is due to not having the proper tools or know how. From day one Rane should have just had all their hardware be class compliant.

Yep, which is crappy business practice and totally unacceptable, especially for customers who plunked down around $3,000 on a mixer to then basically be told "sorry, you're outta luck because we don't support the mixer we just sold you". Anyway, like I said, we've had enough of this BS from InMusic, which is why we unfortunately got rid of all our Rane gear. We're not playing these types of games with them. RIP the real Rane for 5+ years ago when it was a US company with outstanding customer service and support. Legendary in fact within the industry.

+1

I can't argue that at all............. The ONLY one aspect I can sympathize with is the idea that we may not have seen a Rane at all if the "hand-off" came with an obligation to support all prior HW as I can't see anyone scooping them (or any company Vextax for example) up if this were the case.

Vestax was reborn as stpVx, years ago now. I'm not sure why more didn't get that memo? Accordingly, their first new mixer is called the 鳳凰「hōō」(Phoenix) stpvestax.com it looks amazing and probably sounds even better. Doesn't come cheap, but I am guessing it is still worth it. Particularly given the spiked prices on mixers I would consider barely better than toys in recent years, getting something with gold plated RCA jacks and analog VU meters for all the channels shouldn't come at bargain basement prices either.

Rane and Serato have always been a bit of a bait & switch with regards to hardware support/longevity. The Rane TTM57SL (the first mixer with native Serato Scratch Live support) I bought when basically brand new, still functions great in Mixxx (my preferred libre/free open source software DVS alternative, though xwax was neat too. I could never settle into Traktor, Ms. Pinky appears to be basically bit-rot, and we're long past Final Scratch days and VirtualDJ & Rekordbox were also basically non-starters for me) even if Serato dropped support for it years ago. Phil Morse of Digital DJ Tips wrote that supposedly Serato dropped Big Sur and Catalina support for the Rane SL4 and earlier break out boxes recently too? I can't seem to confirm this on Serato's official release notes, but given how late to the game Serato was with official support of Apple Silicon, apparently ignoring the DTK (Developer Transition Kits) which Apple sold months in advance of the M1 hardware launch, it wouldn't surprise me, Serato don't seem as if they are an early adopter with hardware unless it is specifically related to deejay gear.

Lamentably, the SL4 is 24bit96KHz natively whereas lot of more recent controllers and mixers currently sold on the market which Serato supports are 24bit48KHz at best. I even bought the Roland DJ808 due to its professed 32bit96KHz recording, but the whole thing feels like cheap plastic and already has a broken up fader on one of the channels. To me, it was a bad investment on overpriced, overhyped premature landfill fodder. Meanwhile, I already own 32bit384KHz recording gear and that's not even the high end in the industry (which is closer to 64bit784KHz these days without getting into less common DSD stuff) though at least that is the high end of what DMM vinyl mastering houses such as Record Industry in the Netherlands support for digital ingest.

For those who don't pay close attention to vinyl mastering precisely 0 of the surviving DMM lathes still exist in North America Of the remaining 7-9 DMM lathes which are estimated to still be in functioning order, they are all in Europe. Meanwhile, after the Apollo Masters Corporation fire in February of last year, only MCD in Japan is still producing lacquers for the few hundred (perhaps fewer?) lacquer lathes left in operating use globally. This was foreshadowed in 2011 with the Tōhoku earthquake, which impacted MCD's lacquer production line which also caused a bit of a hiccup back then. At any rate, I've been seeing various vinyl preorder ship dates since slipping and being delayed upwards of 8 months or more. This was predicted in February of last year, but the pandemic obviously made everything worse and unfold in slow motion.

Hopefully if Serato is truly dropping SL4 support and Rane considers that legacy, it implies Rane/InMusic may be working on a higher bit rate audio interface? Until a hypothetical SL5 is released though, I do not see much gear that is worth buying, very little on the DVS market is anything approaching an upgrade from what I already own.

The fact that they were reborn is LITERALLY why they were used as an example as they are similar in the fact they are not supporting legacy HW either.............. FWIW we got the memo over five years ago about this mixer with sales commencing in 2016??? Perhaps others were just able to read the writing NOT included on that out of date website resembling the old Vestax leading one to believe (practically know) this will never actually happen.......
As for the rest some I agree with. Most I don't. Some is opinion, some is not (for instance the MP4 was in fact the first mixer with native Scratch Live support not the TTM57SL) either way though I think there is an unfortunate truth being told here in that nobody is racing to fill the "hole" being left here and unless people no longer like money one can only assume why...

Good catch on the MP4, I don't rock rack mount mixers, never have, maybe will someday, but in decades, I never have, so it slipped under my RADAR.

I rack mount servers though!

I also prefer having complete access to source code more than I care about making sure someone else's bills get paid while mine don't, so I am not too sure about liking money, it seems as if it is the root of all evil.

Supporting so-called "legacy" hardware is a great fit for libre/free open source software, which is why I mentioned Mixxx. Strugglin' to keep up with the Jones' is a great way to end up impoverished. I think a lot of the gear being peddled today is asking prices which are not merited, that is my opinion, but I put my money where my mouth was, and wound up with a lot of bad experiences and little in the way of commercial support for things I paid for, so I don't really think that is reflective of gettin' my moneys worth.

Software and hardware aren't food. They stick around, long after the fact. Serato already wants to go the way of subscription models with how they're marketing Studio. I think the writing is on the wall as far as how quality software survives, but that's a discussion not fit for this forum. "hole" or not, I suspect it's more to do with who is skratchin' whomever's back with corporate kickback cronyism rife in an industry which has been plagued with payola longer than DVS and the CD have even existed.

The stpVx memo mention was more: it seems like no one has wanted to pay that pied piper. Since the 鳳凰 was released, I've only seen one shop even attempt to resell it, and that was in the UK and given their mark up, it was close to £10,000 street price. That is way too rich for most in an era plagued with MP3 beatport streamin' deejays and $200 plastic controllers who couldn't give a.f. about honesty. But hey, I'm probably preachin' to the choir right? Just like Gregory C. Coleman was paid his due? </sarcasm>

Moral of the story here is to not support Rane anymore by buying anything from them,

if they don't want to support loyal customers then why should loyal customers support them,

Let them go under

Exactly.
That’s one of the reasons why i switched to Pioneer and completely reject Rane and their parent company.
