Program Change midi bridge freEWI iphone4 Roland UM one

Hi gurbz ,

Your setup sounds fine from how you describe it.

When the program change is not forwarded you say you see the MIDI ins (left) blinking but not the MIDI outs (right). Can you check this again? If the FreEWI input (left) is being flashed in MidiBridge then I would expect its output (right) to flash also if it's active. 

I think this could be due to FreEWI's idle timeout (15 minutes) kicking in. When it doesn't see any MIDI for 15 minutes and it's in the background, it will suspend to preserve your battery. When this happens, I would expect the program change not to be forwarded and in MidiBridge I would expect UM1 in and FreEWI out to flash and then nothing else.

If this is what is happening, maybe we could remove FreEWI from your setup and do your program change remaps via the Stream Byter? (I can help with setting this up)

First, I would like to verify that it is indeed FreEWI's idle timeout that is the issue, so if you can reproduce the program changes not being forwarded with MidiBridge is in the foreground and observe exactly which of the 4 ports flash and which do not, then we can decide what to do next.

Hi gurbz,

OK, so it isn't the idle timeout.

Yes, your routing is correct.

When you get a 'no response' situation which of the 4 ports in MidiBridge flash?

Are you using an Apple Camera Connection Kit (CCK) to connect the Roland or is it a third party cable?

Do you have any other MIDI interface you could try with temporarily?

Hi gurbz ,

OK, that seems that FreEWI is not passing on the event if it's port on right flashes but its port on left does not. I think your CCK/UM1 are A-OK.

Not sure why FreEWI would do that; it only knows how to forward events and has no concept of blocking. However, I would like to try and take it out of the equation as a test.

The Program Changer is more useful if you want to issue program changes when you load a scene.

For remapping program change numbers, we will use the Stream Byter.

Can you give me, say 2 or 3 of the mappings you setup in FreEWI and I will send further instructions.

Regards, Nic.

I think I also understand setting up the scenes and program changes in MidiBridge without freEWI
I let you guys know what comes out of these alterations

Hi gurbz ,

Yes, setting idle timeout to zero will definitely break things. Try switching it to something like 15 minutes and that may just solve all your problems. FreEWI has no such setting. It is defaulted to15 minutes.

If you still want to try program change mapping in MidiBridge, here is what you can try:

Connect UM1 in to UM1 out directly. Disconnect FreEWI routings.

Touch 'beaker' button on UM1 in (left) and the touch '(i)' on Stream Byter. Press 'On' to enable.

Paste the following into text box:

CX 01 = XX  08
CX 02 = XX 01

Press 'Install Rules' and then 'Done' and 'Done'

Those 2 program changes should now be mapped.
