@jbdevelopment: i've got an extra seq v4light control surface and front plate/ case FS. You're nl / be?

Cool gear the ax100mkii.. http://www.rolandus.com/products/details/61

Nääää, integrating the DB50XG driver into the SEQ V4 is not gonna work: the LPC1769 has too little SRAM to support both. I could try to squeeze out every single last byte, save mem by disabling SEQ v4 modules I don't need myself (like CV). But even then there's only enough mem for a very reduced DB50XG feature set. Dead end street.. TK had warned me, but these DIY spirits made me find out for myself anyway. (Well, coding does not blister my fingers as soldering does...) So the new strategy is to fully develop DB50XG/DB60XG/XR385 functionality into the MIDIO128 platform. Unless you guys & gals think its better to port to the NG? Now I come to think of it: a Midibox DB50XG sound module in a commodore datasette case might look quite cool..

Yes a c64 PSU works on my SEQV4 as well. USB power depends on the current consumption of the LCD displays. Computer ports mostly supply only 500mA.

Thank you TK& Luke for double checking. I found the error: it was in my thinking and not reading the manual thoroughly enough. Use this button to speed up the encoder and datawheel increments/decrements. Note that on a parameter layer change, the FAST function will be activated or deactivated automatically depending on the value range which is edited by the rotary encoders.. This useful feature can be deactivated in the MBSEQ_HW.V4 file. Apologies for polluting the forum with silly stuff...

You're right: it is strange indeed and why would you change a winning concept? But would it be the switches if it works properly in tracks configured for notes? Is the 4.075 prebuilt still available? This would allow me further testing.

To clarify: if i have a track formated for notes and press&hold mute, the seq displays Note Vel Len Roll and allows me to mute these items. When I release mute button, it shows 1 ... 16 and allows to mute tracks. This is normal. However, when i have a track formatted for drums, I used to get the option to mute BD, SD, OH, PH, CH etc individually when pressing&holding mute. Now it goes directly to track mute 1..16 even when mute is pressed and held. I tried different tracks I deleted the prebuilt v4.075, so i cannot test the version differences anymore. Is this issue replicable or only in my setup here?

Yes, I lost the drum mute as well. I had been fiddling with my setup and thought I s€%ed sth up. Is it something in the 4.076? Awesome tutorials, yes indeed!

Yes a midibox seq v4 will work with a db50xg. In any case the seq v4.075 with an lpc17 core. I built a db50xg into a midio128 controller. Software in the programming forum.

Thank you, I will certainly try the voices. I know the db50xg has qs voices, but found some info that the db60xg and xr385 don't. Would be great if they do have them!

Update: setting BLM8X8_DOUT_GP_MAPPING 0 in the MBSEQ_HW file resolves the problematic behavior of the buttons. Mysteriously.... But it switches the GP leds down completely. Also mysteriously... I might throw in a DOUT for the GP leds to get this baby to work. But why does not it ....??

Hello all, My SEQV4 is nearly finished but not running completely smoothly yet. Any clues would be appreciated. The build: an LCP17 core with SD card and, DIO MATRIX and one DIN module, no IIC midi out. The CS is a matrix ' wilbastyle' , based on the schematic in the forum. Buttons and leds are matrixed and on the DIO matrix, so is the datawheel and the encoder button lines. GP encoders are on the DIN. The hwcfg file is adapted accordingly. The software is 4.075, i tried the prebuilt and a self-compiled with #define MIOS32_IIC_MIDI_NUM 0. The CS was tested thoroughly: With all buttons 'disabled' in the hwcfg file, the report properly: [84782.181] [SEQ_UI_Button_Handler] Button SR:21, Pin:3 not mapped, it has been pressed. [84782.309] [SEQ_UI_Button_Handler] Button SR:21, Pin:3 not mapped, it has been depressed. I tested leds with the multimeter: neg on the dout cathode lines, pos on the out anode lines makes all of them light up properly. So i concluded the hardware is fine. Now the problem with my SEQV4 is that it hangs in certain menu pages. It lights all GP leds, looses buttons control and only moves the cursor when I turn an encoder. Only resetting will help. Some GP buttons also behave strangely in edit mode: They only switch notes on, but not off any more. Others properly toggle notes on and off, others don't react at all in edit mode. This also hangs up the SEQ. But when I go to the mixer (or some other) page, all buttons and leds behave normally. I can also more safely with the GxTy buttons from G1T1 via G1T2 to G1T3 and back again, the same for G3T1 - G3T2 - G3T3. But when I go to T4, G2 or G4, it hangs. But when i move through the tracks e.g. in fx mode (with the data wheel), the GxTy led are well behaved again, same in the utility page when moving enc 1 to select group/track. The behavior puzzles me. is it a software issue and if so, why only here? Or is it an unseen hardware issue which eludes the "Button SR/ Pin not mapped" test and the multimeter LED test? I'd love to hear you debugging suggestions and get this baby running properly!

Oh that's great norbim. I couldn't get it to work on the clones. If you have voices to share, I d be glad to try again. Maybe my code is wrong.

Hello sompost, If you're experienced with pics and asm, that's great. I' m always building code and then spend even more time simplifying it. I started this in C but might have should have in C++. Less lines & trickery, more power. I like the esoteric ring of virtual template polymorphy and operator overloading. The clones won't give you QS voices. They are OEM version of the db60xg, which gives you audio-in in return. There's also a sw60xg but that's not a daughter board but a full pc sound card. Check out http://www.studio4all.de/htmle/frameset090.html I think the clones feature sections 3 and 4. I'm now building the code, sparx will test it. Have fun!

Hello sompost, I think you are correct: no QS voices on the clones. If you have an unbroken link, please post it here. Good luck with the core8 coding. asm right? Or get a lpc17 core and come join the fun! There are more xr385 heads out here...

+1 New version Beta 0.4.2! Bugs fixed in synchonization of voice menu and incoming midi. Now working properly both in GM and XG. Beta 0.4.3 has global function master volume, master tune, transpose implemented. I've got a real DB50XG for a very fair price. Let the feast begin!!

DK38's arrived today in mint condition! My seq v4 wil look soooo cool with them. Thank you Martin for organizing the BO!

Thank you!

Hallo, Hier gibt es auch schon MIDIO128 basierte DB50XG Kod. Noch sehr Beta aber schon teilweis funktionell. Viel Spass!
