Yup. Midi Touch ($9.99) + Camera Kit will get you going with ease.

Although with an Ipad - you will want the Ipad version of MIDI Touch -which is $19.95

My mistake. I thought it was universal app. Totally don't remember paying $19.99 for it. Wonder if I got it during one of those occasional price discount times... Oh well.

I have looked at all the midi data in OSCTouch editor,  they all start with xF0,   That means they are all SysEx messages,  why is that,   Should some of them , e.g. Patch change can be CC or PC message instead?

Because MIDI Sysex is the ONLY path/ method to control EVERY element of the GR-55.

We have to thank Gumtown for snooping and debugging this - without any documentation!

Luckily Gumtown has "been there done" that before, creating third party editors for other Roland gear, like his excellent BossGT-10 Floorboard editor.
 

But simple remote MIDI control of Patch up  / down and making knob / faders for the limited Eight assignable MIDI CC# Continuous Controllers should not be too difficult.


Here's another Alesis I/O dock Core MIDI  IOS app "MIDI Tool box":

If nothing else, you can get some mileage out of copying the CC Message faders and XY pads to your own template, and moving those simple messages over to the MIDI tab on each control.  These can be used with the Assigns in the GR55 to control quite a few things.  Unfortunately, I don't think patch navigation is among them. 

But things like pickup selection, amp selection, etc. are, and if you experiment you can begin replacing these sliders with distinct buttons that call out the components/ positions (i.e. the specific values) you prefer, which could be very useful in performance.

I've said it about a dozen times already, but I think one of the most exciting things about these iOS interface apps (TouchOSC, MIDI Touch, etc) is that everyone can wind up with a UI that exactly suits their own personal preferences.

Thanks!  do you mean GR-55 will not accept standard CC and PG midi control?
I remember long time ago, I can use my GT-5 to send program change message to my GR-55 to select a patch.

Quotedo you mean GR-55 will not accept standard CC and PG midi control?

Quite the contrary - its rather standard in that regard and will accept program change commands  -AFTER you enable MIDI Patch change reception.

And set the correct MIDI Channel too (PATCH CH = 1 thru 16)

To enable MIDI Patch change reception set (PC RX Switch = ON)

See GR-55 Owners Manual page 79



But  it restricts you to a total of eight total MIDI CC# commands which you must manually assign each.
Of the hundreds of available GR-55 effect parameters, only 8 can be controlled at a time using MIDI CC#.

prsrick

So how do you enable MIDI Patch change reception?
What are the allowed CC commands from the short list?

Thanks again!

Elantric

#236
Read post directly above on how to enable MIDI Patch Change reception

This is a list of ALL available Control sources for the  GR-55:
(Observe  that not all MIDI CC# (1 thru 128) are available)
You may create Eight Total Control Assigns from the possible controller sources in this list.

This is a list of ALL available GR-55 FX Parameter Targets you may control remotely using the EIGHT Control Assignments:

#238
Most will discover its easiest to assign the hundreds of available GR-55 FX parameter Targets (as listed in the post above) to the Eight Control ASSIGNS using Gumtown's GR-55 Floorboard Editor :

Thanks again!

Where did you find out all these details?  or am I miss reading in the owner manual?

Right, my mistake.  I'm actually using SysEx for my patch navigation (adapted from a template MCK developed), but yes it should have occurred to me that simple Program Change messages would work!

I've finally started shooting the YouTube vids I mentioned earlier.  Very informal stuff - no editing, just one camera pointed at the iPad while I blather on, podcast-style.  The first two videos are strictly a verbal introduction to concepts, stuff you guys already know, but I hope to have more up soon.  Hope these links work:
