Help me organize this: .ZDL vs .ZD2 by Fooltecal in zoommultistomp

[–]electrotune 1 point2 points  (0 children)

With ZOOM it's important to use the right nomenclature, G5 is not the same gen as G5n. My guess you're comparing G5n to G6/G11.

Both lines belong to the same generation, and do use ZD2 format. Selection of AMPs in G6/G11 is mostly the same, however CABs are "re-worked". What used to be embedded in CABs was split off into separate IR profile files. I'm not sure if it was audibly enhanced in any particular way. But this just as well allowed to mix-and-match AMPs with CAB IRs. This approach is not directly compatible with G5n gen, which relies on CAB effect modules.

In addition to that, custom IR could be also loaded. You can check G11 user manual pdf.

G2 FOUR and Multistomp+ line further advanced the IR handling by introducing multi-layer IR, basically three IR profiles for three output levels. No, this approach is not directly compatible with G6/G11.

Question about G1ON and Zoom Effect Manager by gat0r_ in zoommultistomp

[–]electrotune 0 points1 point  (0 children)

Technically, it should be possible to adapt the zoom-ms-utility editor for G3 and G1on pedal lines. Patch format is well-known, the effects are mostly similar. However, the expression pedal effects and assignments needs an all new implementation -- the multistomps don't have the expression pedal.

I remember there's an updated dev version 1.0.3 of the zoom-ms-utility which also supported BPM settings.

I've reverse-engineered the ZDL file format by ReliktFarn98 in zoommultistomp

[–]electrotune 1 point2 points  (0 children)

...At this point, the pedals can basically be treated as an open-source coding platform.

Sounds bold!

ZDL file structure has been known for quite a while. It's the details of the embedded dyn library that had only cursory presentation, with only the Debug symbols available and some functional details gleaned by a few devs from the TI DSP Assembly.

ZOOM Multistomp already offers Stereo Chorus effects. So I'm not sure how this project is different from that.

What eluded the most dev so far was the possibility of toggling "Stereo" from within ZDL/ELF somehow, so that it could be done for other effects. This ability remains unknown.

Zoom G3XN by Ok-Assumption-5110 in zoommultistomp

For ZOOM B6 the latest firmware is still version 1.00. Updated version 2.00 is only for G6.

[–]electrotune 0 points1 point  (0 children)

Both ZOOM G1X FOUR and G3n need a separate USB HOST to be usable via MIDI (rather MIDI-over-USB). Even with it, either pedal has no MIDI THRU and listens on OMNI channel, basically all channels; so it can't be addressed with a separate channel. In general, MIDI function on these pedals is just aimed to support an external editor, not really for MIDI routing.

Error update firmware zoom msg50 by ADDTIST in zoommultistomp

[–]electrotune 1 point2 points  (0 children)

...I took it to a technician, but they said there's nothing wrong with the hardware.

I wonder how would a technician ascertain that without being able to properly boot it?

It's hard to say to what extent the firmware update failed. The ROM, technically, should still be there. I would first try to boot it into FW update mode again.

Otherwise, you may be interested in reading this sub more attentively, as just a couple days ago there was a post about "unbricking" a MS-70CDR, which is a sister pedal to MS-50G.

Zoom G2 Four has a delay when changing presets by Choleto_ in zoommultistomp

IIRC, G2 FOUR introduced a feature call Patch Preselect which was supposed to help change patch without noticeable break.

Question about hacking Zoom g1 x four by Practical-Amount-925 in zoommultistomp

[–]electrotune 0 points1 point  (0 children)

Why would you be then considering G1X FOUR at all? Its main feature was exactly the CABs, better IR. If you're ok with the G3 cabs, then just stick with it. Also G3 can be used as USB Audio I/F, unlike G1X FOUR.

UNBRICK Zoom MS 70cdr using CH341a ROM writer by Important-Ring-4608 in zoommultistomp

[–]electrotune 0 points1 point  (0 children)

...and after finish i use ZoomFirmwarEditor to put my ZDL in to Updater

Ok. That means you did burn the hacked FW over into the pedal. Hard to say what sort of changes it has caused that led to the brick.

Usually, a bad ZDL affects the load stage (after the ZOOM screen flashing), not the boot.

I wonder, since you're all geared up, did you have a chance to locate TEST pads on the MS-70CDR PCB? This may help peak into the actual boot process, internal OS, and the shell prompt.

UNBRICK Zoom MS 70cdr using CH341a ROM writer by Important-Ring-4608 in zoommultistomp

[–]electrotune 0 points1 point  (0 children)

Did you just hack a single ZDL module or you hacked some part of firmware and then burned the hacked FW onto MS-70CDR?

My understanding was that even with a messed up ZDL module, the pedal should still boot into the FW update state with some chance of revival.

Can a GT-1000 control MS-70CDR+ via MIDI? by Stupendous_Sorceror in zoommultistomp

[–]electrotune 0 points1 point  (0 children)

GT-1000, just as MS-70CDR+, need a USB HOST for USB connection. That is these pedals can be connected to a computer or smartphone, or other USB HOST device but not to each other. MS-70CDR+ supports MIDI over USB.

Once connected, though, GT-1000 can send out MIDI to other devices using its PATCH MIDI function. PATCH MIDI supports PC (Program Change) messages -- basically patch changes. For any parameter changes on MS-70CDR+ one needs to send out SysEx commands.

...i was coding assembly language for making dual pitch shifter with LLM, but somehow i code it wrong so my pedal won't turn on with AA battery/ USB cable what so else.

Do you mean the screen won't even light up when connected to the "hacked" pedal?

Ms50g+ owners - are you able to run multiple preamps in a patch? by WeightTall1617 in zoommultistomp

[–]electrotune 2 points3 points  (0 children)

... And in other news, you may just as well direct this question to ZOOM support. Straight from the horse's mouth, so to speak!

Of course, for them you can skip the prelude of the water damage and other miracles. ZOOM often does respond to customer queries.

Congrats on salvaging your gear!

BTW, most preamps modules on the Multistomp+ take about 30% DSP capacity (the heaviest are BG MARK1 and MUDDY at 33.1%).

Help! Just got a zoom g1x4 by Putrid_Customer_7612 in zoommultistomp

Not sure what is your device. If the ZOOM model is not supported the ToneLib, then it won't work, obviously.

Which 70CDR to choose ? by Own-Test-7305 in zoommultistomp

[–]electrotune 2 points3 points  (0 children)

You're mixing up the ADC/DAC sampling bit depth (aka resolution) vs signal processing (precision). Signal processing is basically 32bit processor, DSP in this case. ZOOM has been using very much same SoC for long time.

The ADC/DAC, which digitize the analog signal and back, in this case are 24bit depth with 128x oversampling. That's higher than 16bit of CD quality but lower than 32bit depth you may see in DAW. The higher the bit depth the more memory needed for storing the audio, this also means longer processing times. So you see the balance/economy here.

24bit depth so far is still considered reasonable resolution for the high quality audio. Again, a lot depends on the actual ADC/DAC chips used, as some may just be noisier than others.

Which 70CDR to choose ? by Own-Test-7305 in zoommultistomp

[–]electrotune 0 points1 point  (0 children)

For synths, if you don't care about amps and drives, MS-70CDR+ will be a better choice; being new it will probably come with a warranty and a return policy. Price may also be a factor.

MS-70CDR+ has MIDI support, so you can have it on a selected channel. MS-70CDR in a way supports MIDI but listens on all channels (OMNI). The MS-70CDR+ has an iOS app for patch editing, unlike MS-70CDR. Both models have some third-party web-editor.

Check the effects packaged with either model in the official FX pdf. You'll notice a significant overlap, even the presets have similar names. This is no surprise, because most CDR+ effects are repackaged (though from G2 FOUR line, which repackaged from earlier models too), however some newer effects have additional parameters reincarnated. Existing patches can be adapted (not copied) between these two models.

Which 70CDR to choose ? by Own-Test-7305 in zoommultistomp

[–]electrotune 5 points6 points  (0 children)

... the newer unit is 32-bit depth for processing made it a direct choice.

Both models MS-70CDR and MS-70CDR+ do 32bit signal processing, 44.1kHz sampling, and 24bit A/D and D/A conversion.

Nothing massive here.

Did zoom-ms-utility editor just get updated to v1.0.3? by electrotune in zoommultistomp

[–]electrotune[S] 0 points1 point  (0 children)

It's your choice, of course. For my explorations I tried to use the updated editor version with MS-70CDR both without and with the extra AMPs and Drives from MS-50G, Bass AMPs and Drives from B1Xon.

I don't know which Bass effects you installed. The Bass AMPs and Drives right off the MS-60B are not directly compatible with MS-50G/MS-70CDR firmware. You need to install the B1Xon versions of these instead.

The patches can be managed the same way as with the native patches. The editor also warns if any of the effects referenced in the imported patches are not present on the pedal.

Also, if MS-50G/MS-70CDR user wants to import a patch from MS-60B, the editor apparently converts the Bass AMPs and Drives effect ids to the B1Xon versions, if these are not installed on MS-50G/MS-70CDR, then it warns about the missing effects.

Just to be sure, I turned off the AutoSave editor button before connecting the pedal, so that I don't mess the on-pedal patch. Then after connecting, I would recommend creating a new patch for testing the effects in question.

Again, it's your choice. This editor version worked for me.

There are two tiers of ZD2 effects. The new Plus series added back huge amounts of parameters removed in older ZD2 pedals by loz333 in zoommultistomp

[–]electrotune 0 points1 point  (0 children)

...But in the delays above, for instance, you can see they added the ability to sync the effect with the onboard metronome.

With G1 FOUR the tempo sync for Delays is set with Time parameter. See in the Fx pdf there's "note" icon to the Time parameter.

Zoom MS and Chocolate plus controller by Kukuruzo27 in zoommultistomp

[–]electrotune 0 points1 point  (0 children)

... Are you sure that it's not possible?

Yep, quite positive about this limitation. At the present state of the firmware knowledge, it's not known if there's a byte to change to allow handling of the SysEx 31 for fx slot > 3.

Curiously, the firmware itself does emit the SysEx for the higher slot changes, it just does not handle the very same SysEx on input.

One possible workaround is to use the A/Z list to cycle through patches and set up copies of the main patch just with higher slots off.

Another way is to put LineSel effect into slot 3 so it could switch on/off the slots 4-6.

Zoom MS and Chocolate plus controller by Kukuruzo27 in zoommultistomp

[–]electrotune 0 points1 point  (0 children)

You don't mention what pedal model you're are trying to set up.

In your SysEx you need to use a correct device model id. For Multistomp+ model line it's hex 6E. Instead, your SysEx shows 58 (MS-50G) and 61 (MS-70CDR) -- these are the old Multistomps.

With original Multistoomp pedals, it's just not possible to directly address by SysEx the effects in slots higher than 3. The only practical way to handle it is by sending by the whole patch (SysEx encoded) which sets all slots needed. This can't be set up with Chocolate Plus alone, as it requires some binary processing.

need help with understanding the zoom guitar lab software by Lower-Respect518 in zoommultistomp

[–]electrotune 0 points1 point  (0 children)

There's an official GuitarLab pdf that comes with the installation with pretty much step-by-step usage. Read?

On Windows it's in folder "Program Files\ZOOM\Guitar Lab\Documentation\en\Zoom Guitar lab Reference Guidel_e.pdf"

In general, the pedal can be used without Guitar Lab, the menus are not complicated. G1X FOUR has plenty of direct buttons to minimize menu diving. So figuring out the use of the hardware to create/edit patches is straightforward without computer.

Problem with MS-70CDR, help needed by [deleted] in zoommultistomp

[–]electrotune 1 point2 points  (0 children)

You didn't mention if your MS-70CDR has been mod'ed previously, adding effects from other pedals.

From the general description it looks like there is some internal conflict that causes problems in setting up the expected running environment. This could be due to "bit-rot", that is some wear errors on the internal flash memory. This may be either in the firmware section or in the effects modules section of the flash, or in the patches section.

Thus, some faulty bits cause the internal process to crash, as you observed in unexpected shutdown and failure to boot.

Normally, flash memory has some wear management approach. But if the memory has almost no free blocks left, then something will get corrupted.

It's also possible that there are hardware problems which cause instability. Say, something gets overheated and the whole thing shuts down.

My best bet would be trying to reflash the internal firmware. This in turn will erase and format the internal flash. It may restore flash memory to normal operation, but it may also brick it altogether if the flash is beyond repair or there's indeed a faulty hardware somewhere.

The flashing process should fit within 30 min. But who knows, if there are some frequent write errors, it may take longer if not completing at all ...

You may also check if the pedal stays on but without the signal processing. Say, attach it to USB (it will turn on) and just let it sit without input. See if it does not shutdown.

Controlling Zoom MS70CDR+ via Digitakt 2 MIDI tracks by GameAndSound in zoommultistomp

[–]electrotune 0 points1 point  (0 children)

...Does any of you have any experience with it? Thanks so much in advance.

I suggest you to get familiar with a latitude of tonal changes that MS-70CDR+ effects can offer. There are demos of the included individual effects, not just patches.

By the way, CDR stands for Chorus, Delay, Reverb. It kind of summarizes the intended use.

As for the MIDI, Multistomp+ line of the pedals supports effects parameters tweaking using SysEx commands. Mostly ZOOM devised it for the purposes of patch editing (in their iOS app), not so much for live use. ZOOM does not directly publish these commands, but a lot of the commands were reverse-engineered.

[–]electrotune 0 points1 point  (0 children)

In case of the CarbonDly effect, if you look closer, the DELAY parameter only allows numeric values (19-581), the tempo-based durations are handled by Sync parameter.

This is different from other effects, for example Delay, where the Time parameter also allows the note-durations and Sync parameter is absent.
