What about Zoom G2-Four pedals and their effects? #64

Open maximka1812 opened 10 months ago

maximka1812 commented 10 months ago

Are they also ZD2? They have some new multi layered IR cabinets and stuff.

nomadbyte commented 6 months ago

You mean the G2 FOUR, not the older G2. Do you have one and willing to explore?

mungewell commented 6 months ago

Assume that OP means the G2-Four, so updated the title.

As I understand Zoom has only released app for iPhone/Android, and does not support these pedals via PC. I saw note that iPhone needs a special cable. I can't image that that Zoom would use older format with the fact that these pedals implement IR modeling.

Personally I considered getting one (B2-Four though), but haven't found the right excuse to spend the $250... anyone want to sponsor? LOL

maximka1812 commented 6 months ago

I have B1 Four only.

My understanding is that G1 Four acoustic modelling is using some short IRs already. At least this is that Zooms tells.

Can be cool to find arrays containing IR data and write simple utility to replace them with user IRs, it don't require any code changes.

mungewell commented 6 months ago

@maximka1812 The decode_bdl.py script I pushed at the weekend can also be (ab)used to replace any symbol in the ZD2/BDL code segment.... so if you wanted to (say) replace an IR, in theory that would be possible. Although I recommend it's used with care....

At present it is set up to decode/encode TBLs as float32, but trivial to change to some other format.

The '--list' option will dump a list of all the symbols that exist, if one is called 'COOL_IR_TBL' that would be a suspicious target :-)

$ python3 decode_bdl.py --help
usage: decode_bdl [-h] [-o OUTPUT] [-l] FILE

positional arguments:
  FILE                  File to process

options:
  -h, --help            show this help message and exit
  -o OUTPUT, --output OUTPUT
                        output adjusted BDL to FILE
  -l, --list            list available symbols

I have B2 four.

I'm interested in this project because I only have Android smartphones that doesn't support zoom pedals except G1/G1X.

nomadbyte commented 6 months ago

@Licarde: Do you have a PC (preferably with Linux on it) or such to try out MIDI connectivity? At least to see if the pedal presents itself as a MIDI port.

mungewell commented 6 months ago

@Licarde Hi, I don't know how familiar you are with Midi so please excuse if I'm too simple...

Basically the Pedals are controlled via midi packets, normally a PC would send a series of SysEx packets to query/control the device settings. Midi is normally 7-bit data, SysEx is one of the exceptions where the packets starts with 0xF0 and ends 0xF7. The first 3 bytes of the packet are an 'address', the reset are vendor specific. We see that the 4th byte seems to be a 'command' with following bytes being data

We have figured out that all the pedals (we've tested so far) respond on the same 'address' and thus can be queried/controlled.

For example @nomadbyte had me run the following commands on my GCE-3, whilst it was pretended to be a number of pedals.... https://github.com/shooking/ZoomPedalFun/issues/7#issuecomment-1853222327

ie. 'cmd_44'

$ amidi -p hw:2,0,0 -S 'F0 52 00 6e 44 00 00 00 00 F7' -r temp.bin -t 2; hexdump -C -v temp.bin

I don't know off the top of my head how to send SysEx midi from an Android phone, but it must be possible.... I guess the first thing is to work that out, and then have you try the same on your B2-Four pedal to see if it responds the same.

Licarde commented 6 months ago

I'm a very beginner at both MIDI and Python. Please excuse.

I have Windows only. But if I'm in college, I can use Ubuntu in my lab.

Thanks, lots of new details.

Here's a bash script to list the files on the pedal's internal flash:

#!/bin/bash

sig_int() {
  exit 2
}

port=hw:2,0,0  # your B2 FOUR port 

sysex_find_first="f0 52 00 6e 60 25 00 00 2a 2e 2a 00 f7"  # *.*
sysex_find_next="f0 52 00 6e 60 26 00 00 2a 2e 2a 00 f7"
sysex_find_end="f0 52 00 6e 60 27 f7"

sysex=$sysex_find_first

while
  amidi -p $port -S "$sysex" -t 1 -r temp.bin > /dev/null || exit 1
  trap sig_int INT TERM EXIT

  [ -s temp.bin ] && ( tail -c +16 temp.bin | head -c 12 | cut -d '' -f1 > temp1.bin )
  [ -s temp1.bin ] && cat temp1.bin
  sysex=$sysex_find_next

  [ -s temp1.bin ]
do true ; done

amidi -p $port -S "$sysex_find_end" -t 1 -r temp.bin > /dev/null

Copy the script's text into a file, then make it executable chmod +x thefile, then run ./thefile

It lists the file names, one per line.

nomadbyte commented 6 months ago

B2 FOUR has 300 user patches, 10 patches per bank (30 banks).

Here's how to dump a selected patch and the current edit buffer. For the test, you need to select some of preset patch, say, "001: DamnTime2022" and then dump the data, so we could compare the patch/buffer size.

## Enable Editor Mode
amidi -p hw:2,0,0 -S 'F0 52 00 6e 50 F7' -r temp.bin -t 2; hexdump -C -v temp.bin

## Show current Bank and Program (Bank-MSB, Bank-LSB, Prog)
amidi -p hw:2,0,0 -S 'F0 52 00 6e 33 F7' -r temp.bin -t 2; hexdump -C -v temp.bin

## Dump current edit buffer
amidi -p hw:2,0,0 -S 'F0 52 00 6e 64 13 F7' -r temp.bin -t 2; hexdump -C -v temp.bin

## Dump selected patch (Bank-MSB:[00 00], Bank-LSB:[00 00], Prog:[00 00])
amidi -p hw:2,0,0 -S 'F0 52 00 6e 46 00 00 00 00 00 00 F7' -r temp.bin -t 2; hexdump -C -v temp.bin

## Disable Editor Mode
amidi -p hw:2,0,0 -S 'F0 52 00 6e 51 F7' -r temp.bin -t 2; hexdump -C -v temp.bin

If you want to select a patch directly, just pass it's Bank (MSB, LSB) and Prog MIDI codes. It's just common MIDI (not SysEx), so should work even without Editor Mode, well, it used to.

## Select the third patch in the second bank (2*10 + 3 = 23, "023"); indexes are 0-based

amidi -p hw:2,0,0 -S 'B0 00 00 00 B0 20 01 00 C0 02' -r temp.bin -t 2; hexdump -C -v temp.bin

WOW! Here I am on MST, and when I wake up it's like Santa's Elves have been super busy :-)

@Licarde Thank you so much for this testing and the information you have provided is super helpful.

It would seem that the B2-Four pedal is a very close relative of the B1-Four, and the fact that it is responding to these commands suggests that it would work OK with the Python scripts as they are. The scripts also run with Python on Windows, I used the py2exe method to include a 'pre-built' binary in the zip under the Releases sections

https://github.com/mungewell/zoom-zt2/releases

The scripts need the Construct module, and use WX-Windows for their GUI display. You mention that your college's lab run Ubuntu, do you have scope for installing additional Python modules?

BTW what are your interests/hopes with/for this project? Are you studying programming??

  • ZD2 files for B2 FOUR are likely different from what was made for older models

Although we can't (for copyright reasons) share these files, I did upload a 'master list' of all the effects that are referenced in Guitar-Lab and this includes the MD5 sums of the ZD2 file.

https://github.com/mungewell/zoom-zt2/blob/master/zoom_fx_AllZDL7/master.txt

The GUI script contains has a 'download' button on the 'files' tab, if one or two ZD2 could be manually downloaded and checksum'ed that would answer that question.

... it is responding to these commands suggests that it would work OK with the Python scripts as they are.

Well, it's still a new device. So, it'd be more prudent to keep the initial analysis in read-only mode until we figure out what's the same, what's different.

It's tempting to use the zoom-zt2 tool, yet maybe it would be better to use the amidi to dump out data, then safely figure out the differences and chart the next stage.

@mungewell Thanks to you too!! I'm in guitar band club and my motivation is to use the B2 four for both guitar and bass.

@nomadbyte I agree that we should be careful. If the dumped data is completely different from other models, I should not use the tool.

nomadbyte commented 6 months ago

@Licarde: So far B2 FOUR protocol appears very much similar to that of G1/B1 FOUR model family, but we still need to figure out some details, such as:

  1. patch size and format, including the size and format of the edit buffer (dump the data mentioned in the comment above)

  2. size and contents of the effect sequence file: FLST_SEQ.ZT2:

    • for the size, dump the data:

      $ amidi -p hw:2,0,0 -S 'f0 52 00 6e 60 25 00 00 46 4c 53 54 5f 53 45 51 2e 5a 54 32 00 f7' -r temp.bin -t 2; hexdump -C -v temp.bin
    • for the contents, we'll script the dumps also using amidi

  3. internal flash size, dump the data:

      $ amidi -p hw:2,0,0 -S 'f0 52 00 6e 60 29 f7' -r temp.bin -t 2; hexdump -C -v temp.bin

  4. patch edit commands;

  5. details on the effect files; we have some head start on that already, but some questions remain.

Eventually, we may gather enough details to come up with some alternative editor for this model.

Here it is, more differences:

Again, looks like similar PTCF format to one used with G1/B1 FOUR (G5n platform), yet different.

Ok, done with the patch info for now. Thanks to @Licarde we're learning bit-by-bit about the multi-effect platform evolution!

Once you've the access to amidi, let's continue to the FLST_SEQ.ZT2 info and the internal flash size.

@Licarde Again, many thanks for helping us out.

Don't forget that the midi data is 7bit, and needs to be converted to 8bit to interpret.

[edit] Moved the discussion about decoding B2-Four preset to #67

mungewell commented 6 months ago

@nomadbyte I started adding ability to automatically de-pack from SysEx dumps, and noticed that my code uses different 'cmds' to read patch data.

Should these be updated??

[edit] Yes... see #68

nomadbyte commented 5 months ago

Happy New Year! Hope it started well for all of you here.

@Licarde: Any progress with continuing the B2 FOUR exploration dumps?

Licarde commented 5 months ago

@nomadbyte Happy New Year!

I am very busy this month. So I'm not able to contribute to the project. Sorry.

nomadbyte commented 5 months ago

@Licarde : Understood, no problem. Life priorities require attention. Join back in, when you'll have a chance!

I'm currently trying to get B2 FOUR output from the following SysEx commands. All deal with patch details.

Say, select the first preset '001 - DamnTime2022' and then do:

amidi -p hw:2,0,0 -S "f0 52 00 6e 64 02 00 07 00 f7" -r temp.bin -t 2; hexdump -C -v temp.bin

amidi -p hw:2,0,0 -S "f0 52 00 6e 64 47 f7" -r temp.bin -t 2; hexdump -C -v temp.bin

amidi -p hw:2,0,0 -S "f0 52 00 6e 64 42 f7" -r temp.bin -t 2; hexdump -C -v temp.bin

@Licarde Any chance you could try this out?
