Anyhow @mungewell would be great if we can read the higher bits of FXID/GID from patch. I did this in C++ and now I can switch in Rhythm/Loopers. Below you have the FXID/GID necessary to load FX into a slot. IE 16/240, 16/248 etc.
16, 240 == Rhythm
PATTERN 67 states
-
bpm 40 - 250
vol 0 - 100
16, 248 == LP-MONO
Time 0 - 64 (manual, 1, 2 ... 64)
Undo off/on
Stop stop, finish, fade out
Volume 0 - 100
32, 248 == LP-STEREO
same params
48, 248 == LP-MN2 (2 slots)
p1 -> rec
so it need FS1 pressed?
pushing FS2 -> cancel
hold FS2 => clear
FS1 -> recording
push again -> play
again -> overdub'
push both FS1 2 and clear
2nd slot same as single
64, 248 == LP-ST2 (2 slots)I am not sure (yet) if the FS1-4 return any midi. But for sure one an turn these FX on/off in slot - you can only have on type of looper at a time. If you add another then it "works" and the older one show the ! triangle.
For mono variants P1 - N works. For stereo version

00000359And now we have LP-ST2 in slot 1 & 2.For these double slots P5 - 8 control FX params that are 1 - 4 in the single slot version.
For example
pi@raspberrypi:~/Software/ZoomPedalG5n $ ./FXM_PN.sh 1 5 10
10
0a
00
F0 52 00 6E 64 03 00 00 06 0a 00 00 00 00 F7P5's set to 10 = which is a time of 10. 0 => manual 1 => crotchet x 1 etc etc
FX 1 6 0 turns UNDO off 1 6 1 turns UNDO on P7 modifies the stop P8 modifies the volume.
If I look at midi packet in cmidiin
52 00 6e 64 03 00 00 07 00 00 00 00 00 f7
stamp = 0.255346
f0
52 00 6e 64 03 00 00 00 01 00 00 00 00 f7 so it seems to send this extra sysex sentence.

2 years ago I am not quite following your thoughts; it looks like the first/annotated picture shows a SysEx block containing multiple patches, and the later is a single patch retrieved with F0 52 00 6E 64 03 00 00 01 40 00 00 78 01 F7 command.
The ZoomZT download individual patches with the packet = bytearray(b"\x52\x00\x6e\x09\x00") command.
https://github.com/mungewell/zoom-zt2/blob/master/zoomzt2.py#L420
We also use the marker/magic "PTCF" as the start of patch file, at the 10th byte. This is same as used by ToneLib. https://github.com/mungewell/zoom-zt2/blob/master/zoomzt2.py#L432
It seems that the bytes you refer to are BEFORE the "PTCF" market/magic, and therefore not part of the patch per-se. The decode_patch.py tool doesn't have access to these bytes, as they are not stored within the patch file (on disk).
Is the control of the looper (and rhythm/drum machine) part of the patch on the G3n/G5n device, do different patches actually store and control it's behaviour?
I would agree that it would be 'interesting' if the Undo/Redo feature of the looper could be turned on within the G1Four (and family).

2 years ago Rhythm -> Pattern (choose using Knob1 - GUIDE, 8Beats1, etc etc - which I guess are the raw files)
The rhythm patterns are hard coded into the FW, there was some reverse engineer described here: https://github.com/Barsik-Barbosik/Zoom-Firmware-Editor/issues/17
Once the start location is found, they can be extracted with the decode_patterns.py tool, potentially changed and re-embedded (would have to limit/keep the overall size).

2 years ago HI @mungewell
So I have a "fork" of your code. I grab ZT2 From the ZT2 I loop across the ZD2 BUT I also know there are 4 ZD2s (above) related to the rhythm and looper that are no seemingly in the ZT2 I have an alternative handle for these - so I read them in. For all ZD2s I use your code to pull out the 32bit IDs
Now the modern pedals also have Sysex to describe Patch size, nu banks and num patches. I hence modified your code to pull all the patches in and this gets me a "free" decode
From that I build a map of FXID/GID so that I can derive JSON for my models.

What I see is in the "patch" the ID is 28 bits. In the ZD2 itself it is 32 bits. If I use sysex to set the slot I do need the full 32 bits (well it might be 29 ... certainly a top bit to add A1XFour MDLs and turn on Looper/Rhythm on a G3n/G5n). I have not worked out how to do this yet on a G1X/B1X - it seems a different mechanism. But it seems to work on a GCE-3 if it emulates a G5n say.

2 years ago Where did the ZD2 come from to give you these... ?
"group": 30,

"group": 31,
"groupname": "LOOPER",So I derived it from the ZD2s. I can't tell you where I got them from on this forum.

I found reference to them in a 129 file, but don't actually see where the meat is... Are the 30 and 31 group numbers official, or something that you made up?
shooking
commented
2 years ago 30 and 31 come directly from the zd2. But I cannot work out how to get them via your methods. I suspect the midi file method is for ZD2s inside the ZT2? There again you also managed to get guard.zt2 right?
Is there a CLI from zoom-zt2 to get a wildcard file.
Not sure if you have my direct mail or a way to PM me. I dont want to share in public what I found. But by the looks of it you haven't found it yet else you would know where I got the info from - no tease - just trying to protect us both! Once people know the mechanism will disappear. More grey hat than white hat going on here.
mungewell
commented
2 years ago OK, I'll add 30 and 31 to table in zoom-zt2. Isn't guard.zt2 within the 136 file?
You can email me a 'firstname@username.org'.
I'm not sure that another flag (getting busy already) to zoomzt2 is the way to go. You can import zoomzt2 into a small script to call the same functions as zoomzt2-gui does, should be about 10lines of code...
Another thought I had this morning, is whether the rhythm.zd2 contains the drum patterns it plays. If so they could be changed for/by each user to do custom songs, no real point but for giggles we could could do Billy Jean.
Request for comments.
So on the one hand the Rhythm and loopers show up as FX.
They display the following parameters
Rhythm -> Pattern (choose using Knob1 - GUIDE, 8Beats1, etc etc - which I guess are the raw files) BPM VOL
lp-mono: Time, Undo, Stop, VOL lp-stereo: " " lp-mn2: seems to take 2 slots. FS2 controls rec/play, FS3 held down clears lp2-st2: similarly 2 slots.
BUT they are not "normal" FX - they do not appear to be in the ZT2.
I got a G3n at weekend to try to dig deeper - especially regarding how to handle pedal input (since GCE-3 doesnt have pedal but can emulate a B1XFour say)
EXT PEDAL INPUT ON/OFF
on: F0 52 00 6E 64 03 00 0A 0A 01 00 00 00 00 F7 off: F0 52 00 6E 64 03 00 0A 0A 00 00 00 00 00 F7
The above is received, but the display doesnt seem to acknowledge change.
What is interesting is "PTCF" seem "different" for the Rythmn etc. That is one can receive a different output - I attach the files. The raw patches (from a 0x46 request) and a couple of manual sysex I received.
When I try to read factory patches I get things like:
so these exceptions are because I try to lookup the FXID/GID from ZD2 - and I am 100% certain they are not there.
Notice in the manual content I received from rhythm
