Roland E-A7 MIDI Questions #5353
Hi people,

I'm revisiting the idea of switching from Korg PA4X to Roland E-A7 as my main arranger, which I'd explored when the E-A7 was first released. I would like to be able to MIDI a controller with larger keys to the E-A7 if possible, though, since the Roland's keys are short and unweighted.

When it was released, the E-A7 did not support MIDI Remote Keyboard, meaning that I couldn't have the E-A7 view the external keyboard as if it was the internal one. This had implications for playing multiple stacked melody sounds (user programs). I haven't been able to find any documentation on what if any changes were made regarding MIDI in the E-A7 upgrades and I'm wondering if anyone here has any knowledge about this.

Also, although I was able to MIDI up a contorller keyboard (Casio PX5S) today and have it trigger the accompaniement, so I know the MIDI connection is working, I am unable to get any upper tones (melody sounds) to play via MIDI. I imagine there's a pretty simple setting that I'm missing, because I was able to do that when I tried it two years ago or so, but I can't figure out why it's not working today.

Is anyone here able to advise about this?

Thank you!

Unfortunately, I think the BK-7m is the only recent Roland arranger with a 'mirror' mode, where one incoming MIDI channel could be mapped to all the internal splits and layers.

Basically, you are going to have to roll up your sleeves and map the E-A7's Part channels to whatever the Korg is already sending (that's probably easier than trying to make the Korg send what the Roland wants to see, but I may be wrong and the other way round is easier!).

Your problem at the moment probably comes from having either a User Set selected at startup that is set to 'Song' (so the keyboard Parts don't Rx MIDI) or the 'Song' factory Set. Or possibly your master keyboard is transmitting on the wrong channels.

But sadly, a 'mirror' mode (MIDI Remote Keyboard) isn't available. Feel free to contact Roland and ask for it to be included in future models. I also consider it essential to easily connect to MIDI pianos, etc..

Dang, I was hoping that had changed since the first OS! I'll email Roland about it again. It seems like a no-brainer to include that as part of the MIDI spec.

If the User Set is set to "Song" (or it's the factory one), what parameter(s) do I need to change to get it to work as expected?

Thanks much for the help!

It's actually not part of any defined MIDI spec. It's a proprietary thing, part of the OS, and done a bit differently on a variety of other arrangers. But it is is by no means universal on all other types of arrangers. Some have it, some don't.

But yes, it is a VERY handy thing to have, particularly for those wanting to use a stage piano to control an arranger. You might try pointing out to Roland (who sell MIDI stage pianos!) this fact! :evil:

Roland E-A7 MIDI Questions #5362
My experience with my EA7 is that Upper1,2,3, & LWR correspond to midi channels CH 4,6.13. & 11. The Korg midi CHs are respectively 1,2,3 &4

In my case I wanted to midi to Nord bass pedals midi CH 3 and ended up buying a midi channel converter:

This unit allow me to switch transmission channels by means of Dip Switches on the unit to match Upper1,2,3, & LWR

Roland E-A7 MIDI Questions #5363
Arranger manufacturers still have a long way to go to make it easy to MIDI two arrangers together...

For me, one of the primary problems is that all the codes for arranger operation (Fills, Intro/Endings, Breaks etc.) are completely proprietary, so the codes for a Korg won't drive a Roland, and the codes for a Roland won't drive a Yamaha, etc., etc..

This basically leaves us restricted to using the Keyboard Parts, which is so wasteful. Imagine slaving two different arrangers, and using the drums and bass of one arranger and the guitars and strings of another, the multipads of one and the audio loops of another...

Find two similar styles on two different arrangers, and the combinations and permutations give you an almost endless variety for style play. Even two low price arrangers like an E-A7 and a low end Yamaha would offer more variety and choice than any high end single arranger. But until the two can be slaved and follow the controls of one, we are out of luck, or forced to do arcane MIDI mapping tricks through a computer.

You'd think, with arranger sales slipping worldwide, the arranger makers would put their heads together and standardize, but nooooo! :S

TBH, Yamaha would have the most work to do, because, although they use different PC# codes, Roland and Korg are fairly similar, but Yamaha still do it with sys-ex (which makes editing it a PITA as well!). But if all the manufacturers got together, I'd expect to see a boom in sales, as there is honestly little point in slaving two Roland's, two Korg's etc. together... They sound so alike and share so many styles, it's kinda pointless.

But a Roland rhythm section with Yamaha guitars and multipads... That would be a potent combination!

That might be neat, although I imagine there'd be much style editing needed to really maximize that and blend the styles/pads.

Well, obviously, it wouldn't work with any two styles, LOL!

But a couple of rock ones with the same basic groove, a couple of bossa's, some hiphop, some of the jazz things, yes, TBH, I'd think little to no editing (other than getting Part volumes balanced) would be necessary.

Sure, you can tweak it out to your heart's content, but I see no reason why a considerable number of styles wouldn't match up quite well OOTB.

Probably the only new thing this would need is a way to silence Intros and Endings on one of the arrangers. It probably needs a Start command at the end of the sounding Intro, as Intro length varies on all styles. But pretty much all arrangers have a one bar count-in Intro which could play simultaneously, if they can't standardize the others...

I've played with Korg's, Yamaha's and Roland's, and I can definitely remember hearing styles that I thought fit together quite well.
