Did a simple test with Midi-Ox to change MASTER_ARP_NOTE:

F0 18 0F 00 55 01 02 04 05 dv 00 F7 [hex values]

where dv = data value.

The range is really 1 to 19, but both 0 and 1 set the arp note value to to 1/32 and anything over 19 will also switch the value to 2/1.

I believe the novation template editor uses dv to stand for data value; double check that. 04 05 is the <xx, xx> for master_arp_note; 04 08 is for preset_arp_note.

IMPORTANT: You need to use PRESET_SELECT (id = 897 (01h, 07h) to tell your e-mu which preset you want the subsequent sysex data to affect. (Or LAYER_SELECT - id = 898 if changing later level parameters). If you are using the edit buffer, set the preset_select to -1 <7F 7F>.

Note: you can include multiple address value pairs <xx, xx, yy, yy> in a single sysex message.

Its been a while since I have done parameter manipulation via sysex (other than little tests like this), but I believe when you edit a preset other than in the edit buffer, you are editing it in memory.

If that's the case, I am not sure if changing the value while an arp is playing with change it on the fly.

So, I'd suggest setting up the knob/slide with the master_arp_note. Once that is working, try it with an arp in the edit buffer. 

Right now I don't have any hardware to simulate what you want to do (on-the-fly changes), so I will probably just try it with a sequencer.

Hope this helps.

PS: I gave it a try using MIDI-OX to send changes while an arp is playing and it doesn't do what I assumed you were trying to do. 

Ahhhhh. I see. I was testing in audition mode with patterns, but note_value is for non-pattern modes!!! Guess I will have to hook up a keyboard.
