How to establish a stable MIDI routing configuration for MainStage, iPad Pro with forScore and two external keyboards?

Many thanks for your replay.

I do also suspect my problem is the communications between the "actors": MacBookPro, iPadPro and PA5X Keyboard ( the other keyboard I temporary off ).

I wish to share my MacOS Config ( MIDI Setup ). Do you notice something unusual or wrong ?

Although all elements are connected to the two MIDI USBs of Mac via cable, apparently MIDI Setup doesn't show any interconnection among them.

What is your opinion/experience ? Regards.

Yes I have it (MIDIMONITOR). iPad is in the list and is seen as a MIDI Device. If I change a music sheet from the iPad forScore the MIDI messages are send to MainStage ( I see the exactly same massages in the MIDI Monitor of MainStage ), but I do not see exactly these messages to be sent to PA5X ( in both MIDIMONITOR and MIDI Monito in MainStage).

I created an External Channel Strip: output is SOUND PA5X ( not PA5X KEYBOARD ) and Channel 1-16, but no messages are in the MIDI Monitor reports.

I do not understant why there is no flow inside MainStage.

Keyboard preset in the PA5X has Control Change at Channel 16.

At Concert level here is my setup ( see the picture ).

Thanks for your exchange of information. I do appreciate.

Yes, I use the Layout mode to map the two keyboards in the Layout canvas. What I cannot grab is the iPad.

You say that iPad should be put in the canvas using the Activity Monitor device. But I cannot figure out how to accomplish this. Any suggestion ? Moreover in MainStage I cannot see iPad as input device in the External Channel Strip (as I would expect to see it there ) but only the two Keyboards. Any idea why ? Is it designed to do not appear there ?

regards

Hi, I think I got a solution. Not 100% satisfied, but I did at least a large step forward.

Now, when I select a Music Sheet in forScore app, I get the equivalent Patch in MainStage on and of course all the two keyboards are set to the requested configuration. This is two way directions: that is if I select a Patch from MainStage it automatically selects the corresponding Song ( music sheet ) in forScore.

In addition I was looking for sending from iPad forScore app to PA5X, a stream of MIDI Control Channel messages to load a specific SongBook Entry from the PA5X ( a king of Patch in MainStage).

The stream, as an example is BF 63 02 BF 62 40 BF 06 00 BF 26 04.

This string would mean ( as per Korg PA5X manual ): send to PA5X at channel 16 ( those are the first 6 couple of digits ) the request to load the SongBook Entry nr. 00 04 .

Now, this is also working, too.

What are the changes:

The main was to flag on at the Concert level the "Send unassigned MIDI to all Channel Strips".

Then for each Patch Setting -> Attributes -> Program Change in MainStage I set the corresponding Patch number.

I also have created an External Instrument Strip with MIDI Out " iPad " and selected Channel 16 ( as I set the Keyboard to receive Control Changes from Channel 16 ). In the Inspector I set MIDI OutPut -> none MIDI OutOut -> Program Change to the corresponding Patch Number.

In the end, I also created an External Instrument Strip to send the MIDI Messages to the "SOUND PA5X". That has MIDI Output -> SOUND PA5X on Channel 1-16 and in the Inspector Midi Input -> none as well as in the MIDI Output -> no Program Changes.

If I didn't set the flag "Send unassigned MIDI to all Channel Strips" to on and I didn't open the External Channel Strip "SOUND PA5X" to all MIDI Channels 1-16 it could not have worked.

Well at the moment I'm satisfied, but it sounds to me not perfect ( as I get extra MIDI Program Changes that I do not understand where they come from and why... but nothing is perfect hehehe ). However I saved this configuration !

I'm going to explore the IAC Drivers and see if I can establish direct connection between each device and have a better debugging and a clean and fast control.

Thanks for your great suggestions as they brought me to this result.

I do appreciate.
