  1. AOUT_NG not working

    Maybe the testaoutpin can help you to make sure the connections are ok to the board. For me it wasn't working neither but when i did the following it started to work.    
  2. Midibox Drum Sequencer

    This is awesome, I also have a TR9090 set of pcb's. Doesn't the TR9090 have a midi to trigger that is able to handle velocity? I mean are you triggering from the sequencer from midi or are you using gates?      
  3. Me too, still interested. Cheers T
  4. SDCard access without removing?

    OK good that you're issue is resolved. Cheers
  5. SDCard access without removing?

    Isn't there a file browser in MIOS studio?
  6. Aout_NG Not working on midibox seqv4

    I am not able to reproduce the bug at all. Aoutng just working fine.
  7. MBSEQ V4 works fine connected to PC but not on external power

    I would try - only the displays and the coreboard - try adjusting the LCD bias. If I remember it correctly there is a trimpot for that on the coreboard. Do I see it correctly and does the Track position display not work as wel? If that is the case forget the LCD bias thing.          
  8. MBSEQ V4 works fine connected to PC but not on external power

    Hi Yes, According the manual a midi box should consume between 400 - 1000 ma, depending on the lcds or the type of leds. What power do your lcd's need. I see on the schematic that both 5 and 3.3 v are supported. Have a firm look at the core board schametic i will say.   Cheers   Tim
  9. MBSeqv4 Power Requirements

    5v from USB is fine, but for the a_out you need + and - 12v. (at the least for the A_out-ng) Currently I am using a DIY eurorack powersupply for testing the a_outng. But I am considering this ones: found this small dc-dc conversters mentioned by Oliver Pichenette @MI ' Traco Power TMR1-1222 or TRN1-1222' Should be able to deliver enought current.  And its tiny so you can build it in to your midi box. Alternatively I am considering to take power directly from a eurorack synth. connecting using a dsub 25.
  10. Aout_NG Not working on midibox seqv4

    Hi T, Only 1 thing i did not mention is that I applied a bit off pressure on the tl074's so most likely i did something wrong. Maybe the contact wasn't ok before. Althought +-12v was there. I will try if i can reproduce it on my side. But if i do than highly likely I did something wrong here.   Cheers Tim
  11. CV question

    Please note that you need d-outs for the gate. so you need a dout board or you need to build some douts yourself. I think I will builld a 3x d- out myself. Cheers Tim

  13. Aout_NG Not working on midibox seqv4

    Hi Slo,  i hope you will solve it and make it working. I still did not have time to do the full testing.  Anyhow good luck and maybe post you progress here. Cheers   Tim
  14. Aout_NG Not working on midibox seqv4

    Btw found this small dc-dc conversters mentioned by Pichenette @MI ' Traco Power TMR1-1222 or TRN1-1222'  so will try to use this for a +-12V psu
  15. Aout_NG Not working on midibox seqv4

    Ah I seem to have sucses.  When I disabled th aout_ng in the config, saved it and turned the midibox off. Then turned it on again, selected - aout-ng and tweaking the calibration voltages gives me output!!!! ITS ALIVE!!! It's to bad that most likely the first dac was fine as well and this does look like a bug. (not sure) I will continue the tests another day. Cheers, F*cking happy Tim
