Mapping of Effect ID: FLST_SEQ <-> SysEx #15

Open mungewell opened 5 years ago

mungewell commented 5 years ago

Getting familar with SysEx control of the pedals, it seems that the command to place effects into the various 'slots' uses a ID as follows. https://www.thegearpage.net/board/index.php?threads/midi-control-of-zoom-g3-video.1033719/page-3

Selecting effect from the editor:
selecting Comp in slot 6 sends F0 52 00 5A 31 05 01 17 00 F7,
selecting MComp in slot 6 sends F0 52 00 5A 31 05 01 19 00 F7,
selecting ZNR: F0 52 00 5A 31 05 01 1B 00 F7
selecting Pedal pitch: F0 52 00 5A 31 00 01 45 00 F7

So the 8th byte is the effect type.
This is consistent with the effect type list below: 17hex = 23 dec
Table: effect types - numbers are decimal:
000, M-FILTER
001, THE VIBE
002, Z-ORGAN
003, PEDAL VX
004, PHASE DELAY
005, FILTER DELAY
...

Do 'we' know if/how these relate to the placement of the effects in FLST_SEQ?

Another reference for the Effect IDs over SysEx https://github.com/sixeight7/VController_v2/blob/master/VController_v2/MIDI_ZG3.ino#L324

Edit: Eek... his quoted numbers are off by 1, array should start at '0'.

So, that page is mostly correct but I found that some of the commands are different for the G1Four.

Turn on/off effect slots
--
amidi -p hw:1,0,0 -S 'F0 52 00 6E 64 03 00 00 00 01 00 00 00 00 F7' - slot 1, on
amidi -p hw:1,0,0 -S 'F0 52 00 6E 64 03 00 01 00 01 00 00 00 00 F7' - slot 2, on
amidi -p hw:1,0,0 -S 'F0 52 00 6E 64 03 00 01 00 00 00 00 00 00 F7' - slot 2, off
etc..

Finding out how to set which effect is used in a slot was a real pain, they've done some weird bit shifting.

hi - wonderful stuff you are all doing. I got a Zoom B1XFour and G1XFour recently. Started down the Wireshark / parse sysex sentences then cut and paste into MidiOx. Anyhow thanks for all you done and if I may what is the best way to contribute some extra(?) info?

For example, I too was stuck on the CMD 31 for g3 v G1X. I could see 64 was the magic string based on USB decoding - glad I stumbled across your work.

So "bypass" of 64 is a special case of setting the FX to 0 right. But do you know it is possible to get the Zoom to tell you current status of FX?

pi@raspberrypi:~/Software/ZoomPedal $ theCMD=64; amidi -p ${MIDI_DEV} -S "F0 52 00 6E $theCMD 02 bp ep 00 F7" -r t1.bin -t 1; hexdump -C t1.bin; rm t1.bin

Here bp is beginning parameter (param - 1 as ever) ep is ending parameter (" ") ONE caveat - if an FX takes up 2 slots (like a Fender Twin) then you need to look a m. m+1 for slot m and all other slots are moved up by one.

EXAMPLE Let's move to patch Randy Train (why not)

pi@raspberrypi:~/Software/ZoomPedal $ theCMD=64; amidi -p ${MIDI_DEV} -S "F0 52 00 6E $theCMD 02 00 08 00 F7" -r t1.bin -t 1; hexdump -C t1.bin; rm t1.bin Show me ASCII for params 0 ... 8 (I guess the most I ever seen is 8 or 9)

pi@raspberrypi:~/Software/ZoomPedal $ theCMD=64; amidi -p ${MIDI_DEV} -S "F0 52 00 6E $theCMD 02 00 08 00 F7" -r t1.bin -t 1; hexdump -C t1.bin; rm t1.bin

And that seems to cover from 100 == 7.0 pg1 to VOL 74 page 3

You get the idea.

Anyhow I am able to read and set parameters, read FX. Working on your issue above to set FX. Thanks for all the hints collectively give thus far.

I think I will start looking at the Firmware - I used to have the Miniak firmware - Alesis/AKAI never published that - managed to crack 3 of the 4 format - multi's was the PITA. Patches (was given), Sequences and Rhythms was fun ;-).

shooking commented 3 years ago

Regarding the "slots" - I can see this has something to do with some index based I guess on the firmware (and related to the order in which the G1X reads stuff)

so as I added more 0's on I can see I am getting the file names? In terms of this current patch FX1 = SlowATTCK FX2 = ZNR FX3 = FD TWNR ... I think this takes 2 slots? FX4/5 = Room FX5/6 = AutoWah

so 64 05 seems to be something related to files?

And now FX1 is on COMP

but clearly more params are required because more often than not this crashes the G1XFour ... will sleep on it.

@shooking

I think you'd be real interested in the sister project which is targeted at the G1Four (and friends): https://github.com/mungewell/zoom-zt2

I had been making notes about the detailed Midi control of the device(s), but I had my pedal die earlier in the year. You seem like you are making great progress, and I would like to collaborate if you want... I can share my notes with you too, but lets open bugs over here... https://github.com/mungewell/zoom-zt2/issues

shooking commented 3 years ago

Firstly wishing you a great new year - hopefully a lot better than the last one :-(

Hi so I was stuck on processing the Zoom output with my Raspberry PI Ctrlr and Lua. Short version ... I have an alternative way of interpreting the FXID, GID from a ZT2 dump

LMT1176.ZD2
1.50
01 20
80 01
AHH these are 8 bit because converts from 8 midi byte to 7
And it is an endianess?
so 80 01 is really 180(h)
for some reason we right shift 5 to get the GID/

So 180(h) >>5 = 0c
   100(h) >>5 = 08
SL = slot 0 .. 8
L1/H1 = low/high value of FX ID (8 bit value)
GS= GID (01 80, 01 00) >> 5

 amidi -p ${MIDI_DEV} -S "F0 52 00 6E 64 03 00 SL 01 L1 H1 00 GS 00 F7" -r pants.bin -t1; hexdump -C pants.bin; rm pants.bin

Long version.

Linux (well RPi at least) ALSA MIDI sysex seems limited to 256 bytes. I was expecting 603 but always came up 256 short ... this lead me to reinterpret data and I see the GroupID shift different to you now. Anyhow I realised some of the file capture commands have a block size. Changed from 0x04 to 0x02 and now I get "256" chunks rather than "512". I hacked at your zoomzt2.py, modified that to accept 256 rather than 512 and now I am am able to grab the ZT2's into LUA at least.

So what? Well I started to unpick what you did with Construct. That was too smart for me ... so I played and now I see the format differently to you - I suspect it amounts to the same thing .. but the swines just ASCII coded things right??

So your decoded comes out with strings like:

I notice you have different interpretations of the <<< >>> stuff. I treat them as follows:

function processFLSTContent() --[[ So we are looking for blocks of headers then content Zoom uses 3e 3e 3e (<<<) and 3c 3c 3c (>>>) to delimit But each record is 26 bytes ... ascii with string termination? Count 3e3e3e. Begin =>0 .. so nothing find 3e3e3e ++ means 1 ie catalog read catalog header find 3e3e3e ++ means 2 ie FX GROUP read group header find 3c3c3c -> next, so 3e3e3e -- read group ending header -- compare with group starting header ie 2 -> 1, so we back in catalog find 3e3e3e ++ means 2 ie FX GROUP read group header keep reading rows (check there is space for another row)

when back to end catalog
if 00 00 or end of bytes then we at end of catalog

within a record the values are \0 delimited.
12 bytes name \0            = 13 bytes
4 bytes ascii version \0    = 5 bytes
2 bytes FX ID?  \0          = 3 bytes
2 bytes 80|0 GID ... I think first is if installed
                            = 3 bytes
2 bytes empty               = 2 bytes

And hopefully you can see I treat each Record (I give away my Fortran roots here) identically. I use the name block to differentiate between the records

Well when I did this the data appealed to my Autist brain ...

header container
    group container
        FX container, repeat
    end group
end header

26 bytes in an FX catalog row??
It seems to be null terminated ASCII?

we cannot get the LMT1176 chosen.
But if I send

run a loop in the background and observe .. holy cow!!!
this gets me the lmt11176!! 0C = 12 ... wtf that come from?

So instead of the rather unwieldy hex strings you get for group ID, I get a simpler form. We definitely get to the same result but for different reasons.

01 10  16 1 dont work. Notice we ahve 80. What do do?
80 01

81 x 8 ??

AHH these are 8 bit because converts from 8 midi byte to 7
And it is an endianess?
so 80 01 is really 180(h)
for some reason we right shift 5 to get the GID/

So 180(h) >>5 = 0c
   100(h) >>5 = 08

Bloody big v little endian -- I missed out 16 bit and jumped to 32 -- always liked Motorola better than IBM.
So I was biased and looking at the data the wrong way.
But now I cannot unsee it -- ASCII and big endian?

So I recoded to swap bytes

So now I can do things like

pi@raspberrypi:~/Software/ZoomPedal $ ./FXM_ID.sh 1 32 640

pi@raspberrypi:~/Software/ZoomPedal $ ./FX_M1_M2_Values.sh 1

|Z Tron........ 7|

pi@raspberrypi:~/Software/ZoomPedal $ ./FXM_PN.sh 1 1 0

pi@raspberrypi:~/Software/ZoomPedal $ ./FX_M1_M2_Values.sh 1

....Z Tron........-10...........|
pi@raspberrypi:~/Software/ZoomPedal $ ./FXM_PN.sh 1 1 1024
pi@raspberrypi:~/Software/ZoomPedal $ ./FX_M1_M2_Values.sh 1
pi@raspberrypi:~/Software/ZoomPedal $ ./GetMoreData.sh  # flush the buffer
pi@raspberrypi:~/Software/ZoomPedal $ ./FX_M1_M2_Values.sh 1
|....Z Tron........10............|

So by introspection we can see the 1st param of patch Z Tron midi [0, 1024] -> [-10, 10] so likely [0, 21] -> [-10, 10]

and repeating similar shows this to be the case.

Nice. I feel some Ctrlr panel comlng along.
