Well, Yamaha couldn't make this any more confusing: 1. The OS downloads page wouldn't list the size, but the update file is hefty 4 GBytes - so they're replacing the entire Preset Wave ROM, not just providing new User samples. 2. The updated Montage M Data List PDF/XLS does describe the new MIDI 2.0 UMP 1.1 Protocol messages for both MIDI 1.0 (Rx only) and MIDI 2.0 (Rx/Tx) high-resolution events, as well as endpoint discovery (with UMP protocol negotiaion) and device information - but there's neither a full suite of MIDI 2.0 messages and controllers with per-note events, nor MIDI-CI features like property exchange and configuration of instrument profiles. (MIDI 2.0 is for USB-MIDI only, as DIN connections cannot support UMP protocol.) Will probably have to wait for OS 4.0 to enable more MIDI-CI and MIDI 2.0 features complete with MIDI 2.0 Clip File format...

Sound demos are obviously intended for people who don't own the actual Montage M yet. Existing owners can just download the update and play with the new Performances.

Some takeaways from the Tech Talk S05E02 above. Enhanced controller resolution is just a step to full MIDI 2.0 implementation, but the UMP protocol is not there yet. Wavefolding is a new modifier block that sits before Filter in the signal path of the AN-X engine. SmartMorph can (obviously) morph between 4 different AN-X sounds in realtime. CFX2 and CP80LA do come as new User samples. Audio quality wasn't great during the live stream, so hopefully there will be OS 2.0 demos on YamahaSynth SoundCloud.

Yes, it will.

Yamaha US product specialist Blake Angelos posted an announcement for the upcoming June 11 Tech Talk S05E02 and shared some new details of the OS v2.0. https://yamahasynth.com/learn/events/tech-talk-s05e02-montage-os-v2-0-and-e-s-p-2-0/ New features include: CFX2 Concert Grand Piano , Synth Space LA CP80 (user samples?) 60 new Performances Shimmer Reverb (master FX) AN-X Wave Folder AN-X Smart Morph AWM2 Element Edit improvements Expanded Softsynth Plugin (E.S.P.) V2.0 MIDI 2.0 high resolution data for note velocity, polyphonic / channel aftertouch, Super Knob, pitch bend, modulation, assignable knobs/sliders, foot controllers, and sustain It wonder if it's a full-blown 128-bit UMP (Universal MIDI Packet) a.k.a. MIDI 2.0 Protocol message format, or just a few high-resolution extensions for the existing MIDI 1.0 protocol, with additional controllers and RPNs lsimilar to High-resolution Velocity Prefix and LSB controllers for mod wheel, volume, pan, exptession, foot pedal etc.

The new video from Scott's Synth Stuff provides a pretty accurate summary of information from this very thread and the blog post by @pjd including my photos posted on Wikimedia Commons, as well as some additional tidbits on the CPU specs and upcoming OS 2.0 - so I highly recommend it for those who prefer visuals over text. Montage M: All the Inner Secrets of Yamaha's Flagship Synth - YouTube https://www.youtube.com/watch?v=OfqUt4kLVaM One issue I would like to address though is the supposedly 'ancient' Cortex A15 architecture of the TI Sitara AM5728 microprocessor. Even though AM5728 was released in 2015, it's still the top-end offering in the Sitara product line, and currently the only one with a TMS320C67xx DSP included. The most recent Sitara AM62x/AM65x processors are a few tiers below and do not include a TMS320 DSP, although they use the 64-bit Cortex A53 architecture (which was released at the same timeframe as 32-bit Cortex A15). As of now, the Montage OS doesn't need 4 GBytes of RAM and 64-bit adressing, as it only uses 512 MBytes of RAM. And processor performance is already like 100x better in demanding editing tasks like Smart Morph patch interpolation - which is claimed to takes 0.2 s (200 milliseconds) on the Montage M, compared to 20 s (twenty seconds) on the original Montage that used the TI Sitara AM3552. If a new Sitara AM67x series woulld be released with most recent TMS320C7xxx DSP onboard, and Yamaha misses a chances to use it in a future revision of the Montage M to improve on the polyphony and add new synthesis features etc., I will be the first to complain about it. Here today, 6he AM5728 CPU seems perfectly adequate for what it does.

If you think you have a defective cooling fan, take your Montage M back to your dealer and have them inspect it and replace if needed. But if they say it's allright, you need to start assessing the noise at the exact same moment you're playing the actual keyboard, preferably with your headphones or speakers on, and stop monitoring it from another room. Hell no, each to their own: engineers design digital musical instruments, 'pro users' whine and rant.

Desktop PCs have several different cooling fans for PSU, CPU, and GPU (if you have a discrete graphics card), the latter two with variable rotation speed controlled by temperature response curves in the UEFI BIOS / firmware. None of these fans are heavy enough to cause any vibration - what you're hearing is likely an increase in airflow when a higher rotation speed kicks in at some point.

It's just your thought process is too rigid and not flexible enough to synthesize these two concepts into a brand new and exciting one 😂 I'm pretty much enjoying my 320 years old piano technology, 60 years old analog subtractive synthesis technology, and 45 years old digital frequency (phase) modulation and sample-based subtractive synthesis technologies, thank you very much. What is the purpose of overquoting a post from some other forum when it essentially copies everything posted in this exact thread? Too much information for you to handle in absence of a Computer Science degree?

You do realize it's a stock photo by a Brazilian photographer who deliberately set this prop on fire then Photoshopped smoke and flames on top?

Here's a picture of a novel digital musical instrument that had two cooling fans: NED_Synclavier_II_rear.jpg Modular synthesizers, music samplers and most other studio equipment had cooling fans for ages, and I don't recall any of the users obsessing about fan noise, they were busy recording great albums. End of story for me. It's air movement, nothing else. The main board does have a dedicated voltage converter IC for the fan (TI LM73606, ICE02), so I guess Yamaha could implement fan curve settings in a future update. It's a 50 g part, with a 15 g plastic blade assembly - that's not going to cause any vibration in a 300 g metal cover attached to a 18 kg chassis, unless the fan is not properly secured, or the DC motor becomes defective. In my experience, even when the bearings wear out, the blades simply stop rotating. Montage M power consumption is 36 W, same as your wallmart phone charger - have you ever heard about overheating issues with phone chargers? Yamaha PA-500 is rated for 60 W, so it's working at half ot its rated load in the Montage M.

Probably a cost/supply issue. I didn't hear anything about PSU reliability problems on the original Montage, but finding a replacement Yamaha PA-500 unit would be much easier. Even if you're going to spill liquid on the keyboard, a sealed external-type PSU is not going to make much difference. PSU voltage of 24 V and the 5.5 mm DC connector are likely fixed, changes would require a new revision of the AJK daugherboard with different voltage regulator cuircuits, and Yamaha rarely makes such revisions (if ever). FYI the PSU in the original Montage supplies three voltages (+5 V, +15 V, -15 V), so it has to use an internal JST connector. PSU type is not fixed, 24 V is an industrial standard and there are a lot of suppliers for both external brick type PSUs and industrial PSUs; but procurement costs are probably a pretty big issue for such a low volume production as a top-end music synthesizer keyboard. Please share your procedure for "detecting the difference" - does it involve SuperMan Vision? 😆

Not the rear, you need to get close to the keyboard to hear the noise on the Montage M (and the original Montage does not have any fans). But yes, it's not audible from a normal playing position, and hitting your actual keys would make considerably more noise.
