dns370 Posted April 14, 2009 Report Share Posted April 14, 2009 Recently i decided to put all my affords in a sequencer project which will be my very first DIY. But things get a little bit confusing since the new SEQ4 is introduced and according to some posts allready in state of "nearly finished". I am not quite sure if it is better for me starting with the SEQ3 or waiting till the moment when the SEQ4 is officialy released. As far as i understood the only difference on the hardware is the new core-board with the chip - right?On the other side - thinking about my skills in soldering (i did some exercise) - it will take me a long, maybe a very long time soldering parts together. Starting with the DIN-, DOUT- and IIC-Midi-Modules seems to be the correct way for me.This leads me to another question. The new coreboard has allready two Midi-IN/OUT´s. Further Midi-Outs (i need in sum four) requires at last two more IIC-Midi-Modules which means completing a MB_SEQ4 needs following modules:3x DIN1x DOUT2x IIC-MIDI (with two Pic16F88)1x STM32Oh, beside all this i´d like to say "hello" to the community. I am watching this page since two years always thinking about a DIY-project but the time is now critical (i don´t like setting steps in my DAW everytime and in some case i´d like to be complete independent from my computer)GreetingsRobert Quote Link to comment Share on other sites More sharing options...
Futureman Posted April 14, 2009 Report Share Posted April 14, 2009 Welcome!I've personally built 2 sequencers, and helped two friends build theirs, and certainly rate it as a sequencer (The real time recording needs a bit of work, but this apparently is fixed up in V4)I'd just build a V3 sequencer, and wait until the new core is available and then replace it with the newer core when that comes out.. could be tomorrow, could be in 6 months..Shopping list3 x DIN - yep1 x DOUT - Yep2 x IIC-MIDI (If you want.. this gives you extra outs, useful if you have heaps of stuff that responds only in Midi OMNI mode [old midi stuff].. like a JX3p or a SCI Prophet 600 etc..)1 x CoreThen, don't forget the other hardware like LCD's , Buttons, LED's & the case etc..RegardsMike Quote Link to comment Share on other sites More sharing options...
latigid on Posted April 15, 2009 Report Share Posted April 15, 2009 Don't forget, if you want LEDs for V3 Track Group, Parameter Layer, Play, Stop, Pause, Stepview etc., you'll want up to an additional 11 DOUT pins, which equates to 2 shift registers (or DOUTX2).I'm also wondering on the state of the STM Core, as I'm not going to machine my case/start screwing the boards down until I've fit everything in.But, I can be patient... :) Quote Link to comment Share on other sites More sharing options...
dns370 Posted April 15, 2009 Author Report Share Posted April 15, 2009 Thx for the reply.. :)Yes i know ... there are many things to consider when i start with the project. I think it is usefull creating a detailed requirements specification and a step-by-step-plan because i don´t want to get lost and loosing my head. By the way, Mike´s Electronic-Store seems to have most of the parts i will need for the MB_SEQ3 (the modules and chips). For the other parts i will go trough the list which Thorsten provided on the ucapps-site. The case and the frontpanel is not high-priority-rated. I thought about a wooden case.GreetingsRobert Quote Link to comment Share on other sites More sharing options...
Futureman Posted April 16, 2009 Report Share Posted April 16, 2009 For my first sequencer, the case was not a priority either.. just a bit of thin MDF so I could play with it and check out it's layout.RegardsMike0- Prototype 2.JPG1- Early sizing 1.JPG3- Proto face 3.JPG0- Prototype 2.JPG1- Early sizing 1.JPG3- Proto face 3.JPG Quote Link to comment Share on other sites More sharing options...
Futureman Posted April 16, 2009 Report Share Posted April 16, 2009 Then I made my face out of a piece of found aluminium and painted it black.Final face 2.JPGFinal - Night shot.JPGFinal face 2.JPGFinal - Night shot.JPG Quote Link to comment Share on other sites More sharing options...

Futureman Posted April 16, 2009 Report Share Posted April 16, 2009 Bla bla bla bla blaSorry, were you saying something? I wasn't paying attention..I was too busy playing with my SID synth.. ;]Nah, it's all good.. it's documented... honest... would i lie to you?http://www.midibox.org/forum/index.php/topic,12092.0.htmlhttp://www.midibox.org/forum/index.php/topic,12413.90.htmlhttp://www.midibox.org/forum/index.php/topic,11688.0.htmlRegardsMike Quote Link to comment Share on other sites More sharing options...
