So I went down the rabbit hole on this because I have been interested in doing something like this myself.

I know that this is not?rtpmidi, but on the other hand, every single MIDI device I have ever owned that had USB or network MIDI, also still has the 5-pin old-school DIN-plug MIDI jack.? These jacks work about as reliably as RS232 because they effectively are RS232.

Turns out, the old-school MIDI is nothing more than plain n-8-1 serial,?except at a non-standard baud rate (31250) that can't be selected in SIMPL, and also?except at TTL voltages reminiscent of the 0-5v on Crestron's IR-drivers-as-serial.

However, realizing this, it would be trivial to use a cheap Arduino Uno board to translate input at a Crestron-compatible baud into output at 31250 baud.? Basically to act as a translating bridge.? Then sending MIDI messages from Crestron is as simple as using a normal SIMPL serial send block, and transmitting the bytes out a Crestron serial port, just like any other serial device.

I confirm that in ChatGPT, the prompt "Write me an Arduino Uno sketch that uses SoftSerial to accept serial input at 1200 baud (pin 2 RX, pin 3 TX), and retransmit it as MIDI through the UART at 31250 baud" will provide a correct Arduino program that accomplishes this task (it's like 11 lines long) along with the instructions to flash it over USB to an Arduino board.

The Arduino "MIDI shield" that gives you a proper 5-pin MIDI jack from the Arduino Uno's built-in serial port (UART) is less than $20 on Amazon.? The RS232 board that gives you a regular DB-9 serial port compatible with "SoftSerial" is also under $20 on Amazon (search "Arduino RS232 shield").? Arduino "shield" boards stack on top of one another, so you simply make a small tower stacking these two expansion boards on top of the base Arduino Uno.? The "SoftSerial mode" must be selected on the RS232 board, required to software-emulate a second serial port on the Uno because the only hardware serial port (UART) is tied up generating the MIDI signal.

Two minor caveats.
The slower baud rate is required for the software serial emulation... it's 100% reliable at low baud rates like this... midi messages are very short... you'll be fine sending 3 bytes at 1200 baud.? Don't increase it.? Second, the MIDI shield must be removed or switched off (if it has a switch) until you complete the USB flashing step, because the USB flashing function requires exclusive use of the internal UART (temporarily at least).

Fashioning this adapter, you can then send MIDI messages from a Crestron to your heart's content just by looking up the bytes and putting them in a normal Serial Send SIMPL block.? ChatGPT will even give you the bytes (e.g. "What are the bytes I need to send over Serial to send a "Program Change 5" message on MIDI channel 1?")... Sending raw bytes, you can send program changes, control changes, note messages, SysEx messages...basically anything the MIDI protocol allows.? That's hard to beat!

Yeah it's not rtpMIDI, and requires old school cables, but if you get this working, there's a good chance it will run for a decade without a single reboot or failure!

yes, out of what I used the only thing I noticed was the volume fb. I have edited the module but only for things like volume ramp speed and analog volume input.

we checked & Samsung displays worked with direct connect to CP4
sent thru Atlona boxes. nothing at display - these flashers had visible flashing so easy to check
wiring is pretty simple
what are we doing wrong?

If it were me, for a purpose like this, I would buy an Arduino-type board, put a MIDI adapter on it (such as MIDI FeatherWing), and ask ChatGPT for the code to (as an example) "send program change 5 on channel 1 whenever Arduino pin 12 gets connected to ground".? Then you're not dealing with relying on Windows to stay running, or computers that need updating or rebooting.? Arduinos boot in milliseconds, basically the instant they get power.? Their biggest downside is needing to fashion an appropriate enclosure (though, mounting them with magnets and standoffs inside a metal cabinet often works in a pinch!).

I have gotten some amazing results mixing Arduinos with Crestron.? Crestron can easily signal them via contact closure, or via RS232.

I understand if messing with Arduino it's not your cup of tea.? But being built from automotive microcontrollers, Arduinos tend to be bulletproof when used for the right application (especially so when compared to leaving a Windows program running to do an automation job).

Hi All,

Has anybody implemented rtpMIDI in Crestron? I want to send MIDI messages from a Windows program called ProPresenter to trigger automation cues.

Thanks Greg_B, and ckangis,
Odd, that was the first Module I try'd, and the RS232 had been work'n previously, so I was stump'd it wasn't going smooth.
So then I invested in Changing to the IP Module.? It did compile and upload correctly after I changed out the SonyAVRWebAPILibrary.clz
Thanks both fer yer help.

We're working on a project that we've been seeing noticeable command lag when commands are send via IP to a device (AVpro end-points and Sony TVs(IP control) )
We initially thought it was something with AVpro (IR and serial TV control) most noticeable when ramping volume. Then we set up IP control for a Sony TV, Direct IP from the CP4 and same issue.
Debugger shows the commands sending and stopping with the button press/release, but the TVs keep going for 2-3s most times. with serial and IP control, they are getting to the right level that we send them to, but it seems like the commands are getting buffered some where and lazily doled out to the TVs.
I tried the code on my bench setup and initially I saw the same issues!! but then of course everything started working as expected and I couldn't get it to mis-behave again - This of course is even worse!!!
I still have much to review with the network and other testing, but Has anyone else seen something like this recently???

FYI, I have never had these issues and our code is solid.

The Consumer Electronics Show (CES) is not just a show where new smart home devices are announced by manufacturers.? It is a show where new home health devices are shown for the first time.? Both Withings and NuraLogix have announced new, and innovative, health devices at this year's CES.? My latest article digs into the details of these new products.

You can find the article here:




For those interested in earlier articles that I've written, you can find those here:



I've found a new site to host my blog so for those that want to see even more content I've written about smart home technology you can find that using the link below. The process of exporting all my old content from Blogger and importing it into WordPress was far from perfect. So there are formatting issues with old posts and images that didn't import. I will see what I can do about correcting some of these issues over time.



Thanks

Greg B,
You've used this module successfully in the past for ZA (and AZ other than Vol_FB)?
If so, I might try it and customize it (it does way too much!) as it is just S+ and it actually includes the source code!!? What a concept...

I've about had it with S# and .PKG stuff...

I know this may be late but I have been using the STR-ZA3000ES module for the application market, It does appear to have the volume fb issue others have mentioned, I guess I just didn't notice it the first time I deployed an az with.

Sorry, check the files section, I just added the CLZ with the NewtonSoft fix

Yeah, well..
I'm at a service call that I should have left 3 hours ago.? The old AVR was RS232, So I would have liked to use that instead of trying to get a LAN Cable to the Device. WiFi is not connecting (and it scares me to use wifi, when we like RS232 so there are no "Network" issues).

However, I had already downloaded the STR_ZAXXv1.1_Archive.Zip that you (ckangis) uploaded th the files section.
but when I compile I get a pile of "Newton Jason" Version errors.

I have always used the IP version. Its in the files section -?Sony STR-ZAxx v1.1_archive.zip??
Again, everything works great with the AZ series, except for the volume FB (and a couple secondary commands)

I discussed the issue with my inside-crestron buddy, who originally fixed a reconnection issue that I found back at the end of 2015, but he said that even he didn't have access to the source code...Which REALLY bugs me about the way things have gone since then...

Greg_B,?

Which R232 Module is that?
I'm not seeing one.

Wouldn't v1.007 be a downgrade from the device's current firmware?

Hi All,
For those who might have tried this, iPORT had an interface module (72101) that provides not only POE, but also ethernet for iPads when they are docked.
If you have used them have you had any issues with them?
We have had some issues with the ethernet connectivity even with the SurfaceMount units (fixed wall mount).
Clearly it could be the iPads, which are connected to Ruckus Switches, brand-new and on iOS17 but the behavior seems as if it could be related to the interface as well...

FYI:
?- SurfaceMount units ship with the 72101 POE/Ethernet interfaces, so if you have installed them, that is what is connecting them.
?- ConnectPro WallStations come with the 72109 POE-Only Interface. We swapped these for the 72101 for ethernet connection while docked.

I'm hoping that we don't have to swap out all of the ethernet interfaces...:(

The Crestron Simpl# library works fine for PTZ and for getting media URLS, I’ve used it successfully on several different camera models.?

Ive been looking into this as well over the years. Seems Crestron only cares about Home + Onvif (if and when it works) and doesn't care to work on getting the Simp/# side a way to do it consistently either.?

I recently acquired one of these units for my home lab (I'm an AV programmer) and I'm having an issue with updating the firmware on it.
It currently has the old v1.011.0028 (Sept.2015) firmware on it, but it fails whenever I try updating it.
For the record, I've had to do this in the field before and know how to incrementally step the fw versions.
However, I can FTP the zip, run PUSHUPDATE FULL, and it goes through 99% of the unpacking process up until it says "Performing updates... This will take up to 20 minutes"
This is followed shortly after by "Warning: GetReportDmOutput failed with exception: Timed-out waiting for prompt." and sometimes "PersistentLog is suspended, please contact dealer." before it kicks me back to command on text console.
Running version command after still shows "Cntrl Eng [v1.011.0028 (Sep 10 2015)"
For reference, I'm attempting to use the v1.007.0218 version zip as the first step.

Anyone seen or know how to bypass that error, or what the root cause might be? I've already done init, restore, cleared nvram, and everything else I could think of.
Any help before I can get on with TB Monday would be much appreciated!
