I was just about to dig into a Seq V4 build when I started to see mention of a V4+ in the works. After some reading I was under the impression that to run the V4+ one would only have to update their firmware on a V4 machine, but further reading has led me to believe that the V4+ might actually be its own thing with interface changes, yada, yada. If the former is true I'll proceed with a build immediately, but if it's the latter I'll have to consider waiting a bit until the project is ready to roll . . . or maybe there isn't yet a definitive answer to this question?

openMaster Masterkeyboard Today, i start the development of the openMaster master keyboard. It should be a kind of clone of the "openLabs Neko". Let's bring up some features: 61-key master keyboard computer with an VST host 64 pots (MIDI controller) 16 faders (MIDI controller) built-in hardware sequencer and an audio interface for high quality output If you want to see more of it, stay tuned

Hi Im selling my Midibox Seq V4, it as been in my studio for quite some time now, and it was really fun to built and to use it live. Unfortunately in this last 3 years i didn't use it at all, one reason is that my whole idea of performance didnt involve the Seq, so its time to move on and im betting the one who keeps it will give a proper use to this wonderful machine. Some specs: i have built this monster and it took me quite some time, at the time i was giving my first steps towards electronic diy stuff and this was my first project, lots of doubts and also lots of ideas that come out of this enterprise, luckily this forum always help me a lot, awsering questions and keep me positive about all of it. I didnt built a faceplate, was my intention but as soon i was starting playing with this baby i totally forget to make one, also i like the aesthetic of not having a front panel, the Seq as 2 midi in / 2 midi out but is prepared for one more in and out, (i have put the plugs but didnt solder them to the board), the rotary encoders in the front have the top caps, but they are missing from the photos because i was cleaning it and forget to put em back. The machine is running and dont have any errors or crashes the O.S is the last one, and i can throw a Power supply in the sale, the box was my creation, and is solid pine wood, the connections in the back a a proper newbies work, but its all good, no shorts or bad connections. I dont know what to ask because i cant come up with a value,(for the parts i have spent about 300€, wood box 45€ and a lot of days working in it) so if you can make me an offer i will appreciate, also im looking for modular stuff (Makenoise Modules, Intelligel, and a System A-100 (case) from Doepfer)

hey! i have to program a Sequencer Variante of the MB-SEQ, by using the SEQ_BPM... but before i have to be clear what i want... so i think loud a bit... DRUMSEQUENCERs & ODD TACT (UNGERADE SCHLÄGE) since i work with a guitarist, (which play with a Guitar2MidiConverter) he want that i can program 5er, 6er, 7er since i come from electronic sequencer music, I worked so far with drum-step-sequencers which program that 4/4Tact on a 16x1 LED-Button Hardware, OK lets take a look on something I/we know.: if we talk about LOOP LENGTH, and the Change of it, we have to decide which VALUES are INTERESTING.... so 16 are the maximum amount of visible STEPS on the UI(@once), i call that a PAGE >1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 < 3 PAGES: 4 1PageLoop Length Sel Steps Steps Page 0 0 0 1 1 2 2 3 3 4 4 5 5 6 6 7 7 8 8 9 9 10 10 11 11 12 12 13 13 14 14 15 15 0 16 1 1 17 2 18 3 19 4 20 5 21 6 22 7 23 8 24 9 25 10 26 11 27 12 28 13 29 14 30 15 31 0 32 2 1 33 2 34 3 35 4 36 5 37 6 38 7 39 8 40 9 41 10 42 11 43 12 44 13 45 14 46 15 47 on a DRUMSEQUENCER with 4/4 Tact we always double the Steps, to keep in TACT with MelodySequencers (why? wait, later!): 2 x 2 = 4 (@ME: what is the multiplicator when using 5 6 or 7 TACT???) 4 x 2 = 8 8 x 2 = 16 >>> the maximal visible amount of STEPs on a single PAGE >>> so this is our minimal LENGTH 16 x 2 = 32 32 x 2 = 64 >>> the maximal Length of a Korg Electribe Rythm 64 x 2 = 128 >>> a very handy Length when using whole PAGE-Copy-Paste?, and AUTO-Completion (copy Page 1 to All the Rest...) 128x2 = 256 >>> very long for Drums if using all the Steps in one whole Loop >>> what brings us to another Point: CHAINING PAGES or SETTING LOOP LENGTH lets say a PAGE has 16Steps (@ME 3x5=15, 2x6=12, 2x7=14) Chain PAGE 1+2+3+4 = 4 PAGES * 16 STEPS = 64 STEPS Chain PAGE 1+2+3 = 3 PAGES * 16 STEPS = 48 STEPS... maybe problem: when playing with other Sequencers, e.g.we play a Bass 64 STEPs long... DRUMS: 48*2=96 while BASS: 64*2=128, so the Baseline will differ on its way off fitting with the drums... >>>if i think right? there is no point that they ever will meets on the same point???<<< or in a musical period of time (for me) This is a problem when we separate DRUM and MELODY DEVICES... and change the Length while playing... such SETUP will maybe ONLY work with DOUBLEs OF PAGES ... I dont say its forbidden ... specially in my case ... CASE NORMAL: DRUM SEQUENCE has a rythmic, the Melody has a rythmic >>> if they drift by (not equal @ all)... the listener will not find the COMMON RYTHMIC (especially on long Melody’s) CASE TRIGGERMATRIX: DRUM SEQUENCE is the only rythmic, the Melodys rythmic is ignored >>> the drift that you hear is pitch based, that the played notes ON THE RYTHM are NEVER The same, @ least U find the rhythm... ... since I work on my case, i will not forbidd anything, but i will INFORM me the possible/right next PAGE to CHAIN > ...but before we get to that I have to to inform you how how to handle this CHAINING via a UI (UserInterface): SETTING LOOP LENGTH via 16 Buttons in a ROW: We have 16 BUTTONS that are Representing 16 PAGES (a' 16 Steps) >Loop a single Page > short double Click a button. >Loop from Page eg. 4 too 8 > Click&Hold Button"4" & Click Button"8" (which in First Place visualize Page4, and then Set a 4x16=64Loop to Page 8) So to avoid that 48/64 dilemma, we have to get sure that we only select DOUBLED PAGES, and here i come to the point to INFORM me about possible FITTING PAGES: INFORM: I press the First PAGE (4), now following Pages get enlighten 6 8 12 START DOUBLE END 4 0 4 4 2 6 4 4 8 4 8 12 4 16 20 I decide to press "8", and i now have a 64Step Loop, but I don’t want to set the Loop length immediately, I want it to make it in Sync, I want it to switch by the next DOUBLE... Lets make a shorter example: 64 Steps Maximum is set for this TRACK... this has to be set before pressing the Play button, in order to get a MAIN-Timeline, to that we can return if we want back to the whole loop. A maximum-length-counter will ever cycles from 0-63-0-63 …. it counts the midiclock-ticks, this is our MAIN-TIMELINE 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 0 BAR 1 BAR 2 BAR 3 BAR 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 The Loop LENGTH 0 BAR 1 BAR 2 BAR 3 BAR 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 for me, it is enough, to switch @then end of the current selected Loop New Loop Length: if (step is > 31) {step = 48;} ….. In this case it is STEP 31, where the Next Step should be 48 in a loop to 63. step+1; if(step>maxLoop){step=minLoop)…. NEW Loop LENGTH 0 BAR 1 BAR 2 BAR 3 BAR 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 if i want a more stable play in interaction with melodylines, we just watch out for the Main Time Line, the switching between loop points then will take longer until it is set: in example above, we have a loop from 0-31, while this loop is playing, i decidet to make a new Loop from 48-63... the machine now loops its rounds until the MAIN-TIMELINE comes to Step 48, form now the New Loop take effect... This is no problem with a 4 Bar Track, where the maximum what you have to wait is 3 Bars... but what when you set the Track to a maximum off 16 Bars? ...of course it will take time until it switches... so i would say we make a hardware button, that switch between 1BAR SYNC and MAIN-TIMELINE, where MAIN-TIMELINE would kick you back in sync with extern Melody Sequencers... MIDICLOCK and TACT while 4/4Tact is clear, like shown in the Tutorial 17 (sequencer), its a bit more Brain Acitivity to find out how to work with 5 6 7 9 Tacts Tutorial on 4/4 static s32 SEQ_Tick(u32 bpm_tick){ // performs a single bpm tick // whenever we reach a new 16th note (96 ticks @384 ppqn): if( (bpm_tick % (SEQ_BPM_PPQN_Get()/4)) == 0 ) { // ensure that step number will be reseted on first bpm_tick if( bpm_tick == 0 ) seq_step_pos = 0; else { // increment step number until it reaches 16 if( ++seq_step_pos >= 16 ) seq_step_pos = 0; } SEQ_Handler(); if(seqMATRIX[0][seq_step_pos] > 0){ APP_NOTEPROCESS(0, 36, seqMATRIX[0][seq_step_pos]);}//(u8 port, u8 note, u16 velocity) Notes Back to APP.c } The next thing is to translate that all to 5 6 7 & 9 TACTs on 16*16+X Matrices.... but that is something to sleep over it... good night
