Hi all,
Hope you had a nice xmas!
I just found a ddrum4 on eBay...
What's the difference between the ddrum4 and ddrum4SE?
cheers

There are 2 different versions of the SE 1.5 upgrade though , so there's a little more to it , but yes the standard ddrum4 modules can be converted to SE with the upgrade firmware chip install .
There are however 2 different versions as mentioned which are the 1.50 & the last version clavia released which is the 1.54
The 1.50 will work in most standard ddrum4 modules ( 1.32 , 1.40 , etc. ) Pretty much most of the Red/Grey & Red/Navy faceplate colored modules .
but the 1.54 firmware chip will only work in the SE stamped modules and mostly on just Red/Black faceplate versions . This OS chip upgrades it from the existing 1.50 OS to the 1.54 OS and was basically released when ddrum released there mesh head series pads ( the silver and also the black series mesh pads with no backing panel on the shell and a different trigger design than the previous versions which used the reflector trigger plate design . The 1.50 - 1.54 upgrade took the SE upgrade one step further and gave drummers some extra new features like : Increased stability and pad type options , Higher output volume , Mesh head trigger pad support features .
These were options not avaliable in most older firmware versions on ddrum4 modules .
Upgrading the module is pretty easy to do , as long as you have the proper version chip .
In general though the difference in the dd4 & the dd4SE was more noticable with usage of the Signature edition and Mega drumkits samples , and handled these larger sample files with more stability and better control when using them in the ddrum4 modules .

Sam, I think you've mixed up the firmware versions and upgrade path.
Firmware 1.5 and 1.54 are absolutely identical (feature-wise). There is absolutely no difference to the user. In the production process of the ddrum4 there was a little change in the hardware at a certain serial number. No improvement, nothing influencing the ddrum4 behaviour. Some chip or electronic component was different. I understand this was just due to the availability of some chip (or whatever) necessary to build the ddrum4.
Up to a certain hardware serial number you've got to upgrade the ddrum4 with 1.5 . Only the latest built ddrum4 modules (with the altered hardware) run on 1.54. That means there is no ddrum4 which can be run with both versions (1.5 and 1.54). Only one of them works as it is no upgrade from 1.5 to 1.54. Just a different version due to a hardware change.
I don't know at what serial number Clavia has changed the ddrum4. It was for sure during 1.4 or 1.5. If I recall correctly, it was during 1.4!
that means:
If you have a ddrum4 running OS smaller 1.4 (for example 1.32) → get 1.5
If you have a ddrum4 running OS 1.4 → 1.5 or 1.54 could be the right one (only one of them works)
However most of the ddrum4 with 1.4 had the old hardware revision. If you have 1.4 I would try 1.5 first!
If you have bad luck and 1.5 won't work in your ddrum4 (with 1.4 installed before) it just displays ERR. If that's the case get 1.54. No problem at all for ddrum4 modules with OS smaller 1.4!
Most of the ddrum4 firmware sellers burn the chips on their own. They have one original firmware EPROM and produce copies. I would contact the seller and ask if he can offer both. If 1.5 doesn't work he should offer to send 1.54 in exchange. Or you spend the money on a 1.5 copy with a very good chance that it works.
However, this problem should only be possible if you have one of the rare ddrum 1.4 with newer hardware revision.
The features and upgraded capabilities Sam has mentioned have been implemented before. Mesh head trigger algorithm have been installed with 1.4 already. However if you use mesh heads on your cast precision pads (the ones with foam below the heads) don't use the mesh head settings. Only dial in the mesh head setting if you use the “stealth pads” (free floating head, nothing below, trigger pick-up at the rim).
Clavia started to sell the ddrum4 with the addition “SE” with firmware 1.5. The main difference to 1.4 was the new firmware (1.5) and the availability of the Signature sounds (and the sticker on the module ;D ). If you upgrade the firmware to 1.5 or 1.54 you have a ddrum4 SE. The signature sounds are available via download anyway.
Here is the upgrade history for ddrum4 firmware versions:
The V1.40 software features the following compared to V1.32:
1. TRIG DETECTION ALGORITHMS FOR MESH HEAD
Because of the new types of silent drumheads that are coming into the market, Clavia have upgraded the software for their ddrum4 sound module to include trig detection algorithms for mesh heads. Thanks to the new features in the ddrum4 V1.40 the use of mesh heads together with ddrum4 and Clavia's patented triggers, ddrum Acoustic Triggers or the low-cost ddrum Red Shot Triggers, allows drummers to obtain maximum playing comfort without any acoustic sound, yet with perfect drum sounds in his/her monitor/headphones.
Software update to V1.50.
The V1.50 software features the following compared to V1.40:
1. New Factory kits (F.27-F.99) based on the ddrum4 SE Signature sounds.
2. The output signal level has been raised by 6 dB.
3. The ddrum4 SE module responds to (and sends) MIDI Volume (CC#7). This is global for all kits/sounds.
4. You can Mark entire sound groups for deletion, dumping etc with the Shift-Mark function.
5. You can "disable" the DYN curve to get a non-dynamic sound (75% of maximum level).
6. 9 selectable sound variations for MIDI SDS samples. Variation no 5 is "monophonic" mode (the same voice will be retrigged for every new trig signal).

Wow, thanks guys for the massive amount of info  I bet this will be of great help to all considering getting a ddrum4. I've been thinking about it because I have the cast hihat... I'm wondering how "home-made" SDS samples would work with the ddrum4's hihat function? |

Unfortunately the ddrum4 doesn't support loading own multisamples into it. Well, it does support it but Clavia has never published the format. It's only possible to load Clavia stock sounds.
You can only load own single shot samples into the ddrum4.
As you have a ddrum3 you could use the cast hi-hat triggering the ddrum4 and drive hi-hat multisamples in the ddrum3 via MIDI.
I would love to see Clavia's ddrum4 sound format reverse engineered. This would make the ddrum4 a killer :-)
My advice: Get the ddrum4 :-) Even if you use it only for cymbals I still prefer it over any Roland, Yamaha and 2box.

Do the ddrum4 output different midi notes for the different "opennesses"? I've been trying to crack those stock samples, but haven't managed yet  P.S. I'm starting a new thread in Technical with the purpose of cracking that format. |

Basically the ddrum4 exhibits 8 different MIDI notes for each pad. Each MIDI note corresponds to a certain zone. That's identical to the ddrum3. The hi-hat has 8 notes as well. I have to check the MIDI data how the hi-hat stuff is translated into MIDI (zones, open/close position, maybe aftertouch as well?).
The ddrum4 factory MIDI note settings:
BD: 24-31
SD: 32-39
Rim: 40-47
Tom1: 48-55
Tom2: 56-63
Tom3: 64-71
Perc: 72-79
Cym1: 80-87
Cym2: 88-95
HHat: 96-103

I found this information (grabbed from the old ddrums forum) about the hi-hat MIDI data.
Ddrum hihat sends this data:
Midi Note: Position of the hit
Controller data: Clutch distance from the pad
Aftertouch: Pressure of the clutch over the pad.

You've mentioned the upgrade to 1.5 gives new factory kits (F.27-F.99) based on the ddrum4 SE Signature sounds. I understand these are loadable with v1.4, so I wondered what the advantage was for this aspect of the upgrade? Also, are the cast precision pads (non-mesh) the only ones on the market that deal with 8 midi-note zone triggering? I'm having difficulty sourcing a set and wondered if there were alternatives.

Hi to all,
Glad I found this page! Great recourse
I recently purchased a 1.54 upgrade for my SE (Labeled) Signature Edition. Upon install all panel functions froze and it displayed a "E.42" code. Reinstalling the OEM 1.50 eprom from Claiva solves the issue. However, I'm reading in this thread about the advantages the updates have in mesh applications which is why I bought it in the first place.
Can anyone offer me some guidance on this error code?

Hi @confuzed
The 1.54 version is not actually an upgrade for 1.50, but rather was necessary to accommodate a change in the flash chip supplier (went from Intel to AMD). Any modules lower than serial number DA4945 must use the 1.50 version. The two versions are identical feature-wise. (BTW, mesh head support was introduced in v1.40). I think sellers should include this important information in their listings because once you install the eprom it is likely you cannot return it. I've seen some listings that claim 1.54 as an upgrade when indeed nothing can actually be "upgraded" to 1.54.
Cheers!
Ken
