'F0 52 00 6e 64 03 00 0A 08' commands

[shooking]

So I discovered today two new (?) commands. I will document them in two separate issues.

SUMMARY

F0 52 00 6E 64 03 00 0A 08 nn 00 00 00 00 F7 deletes FX in SLOT nn and left shits remaining FX

EXAMPLE - shift left

Set your preset up to have 5 FX in hex slot 0 .. 4 (1 .. 5 on the pedal)

Initially your pedal should look like

slot	shorthand	FX
0	A	COMP
1	B	RACK COMP
2	C	SLOW ATTCK
3	D	ZNR
4	E	LMT-76

And the initial state is

rpt	0	1	2	3	4
0	A	B	C	D	E

So now send F0 52 00 6E 64 03 00 0A 08 00 00 00 00 00 F7 [[notes later]

rpt	0	1	2	3	4
0	A	B	C	D	E
1	B	C	D	E
2	C	D	E
3	D	E
4	E
5

NOTES: I think the parameter after 08 is where to delete from? Like a cursor.

EXAMPLE - shift left but from slot 3 (hex, 4 physical)

Reset your preset up to have 5 FX in hex slot 0 .. 4 (1 .. 5 on the pedal)

Initially your pedal should look like

slot	shorthand	FX
0	A	COMP
1	B	RACK COMP
2	C	SLOW ATTCK
3	D	ZNR
4	E	LMT-76

And the initial state is

rpt	0	1	2	3	4
0	A	B	C	D	E

So now send F0 52 00 6E 64 03 00 0A 08 03 00 00 00 00 F7 [[notes later]

rpt	0	1	2	3	4
0	A	B	C	D	E
1	A	B	C	E
2	A	B	C
3	A	B	C
N	A	B	C

Each time the Zoom replies PTFC data (??)

I found it when watching traffic for moving FX around in the slots. So my hunch is this is "remove from cursor" and later one would "insert at cursor" to add new FX a slot and shift right existing presets?

Good discover, and write up. I think you are correct, I'll give this a go later this week...

A couple of question:

1. what happens with large effects (ie two screens)?
2. what happens if index is too large, ie 8. on other commands it seemed that G1Four would apply to slot 0?

Merry Christmas.
