  3. trying to understand core32 options for SEQV4

    in MIDIbox SEQ

    Posted

    Hi,

     

     

    I assume since this is for the SEQ with the SD card I would just leave the arrays off.

     

    yes, not required for J16

     

     

    Also I cannot seem to determine what the Jumper selection would be as I find this in the guide. What is expected here?
    J24/J25/J26    3    5V/3.3V supply options for serial ports TODO

     

    J16 (SD Card) has to be supplied with 3.3V, therefore J24 should select 3.3V

    J25 and J26 should select 5V

     

     

    Again, I understand that these arrays are not installed and I could just skip this section

     

    No, please install 220 Ohm arrays for J8/9 and J19

     

     

    I plan to have an external power but not just yet. If a populate these parts but just leave J17 in place for now will it still work? I guess I could just remove the jumper when I am ready for external power.

     

    yes

     

    Best Regards, Thorsten.

  5. Controlling OP-1 with SEQV4 ?

    in MIDIbox SEQ

    Posted

    MBSEQ isn't a USB host device as well.

     

    This could become a feature of the STM32F4 based "MIDIbox SEQ V4 Plus", but it has low priority at my side (because I know that this will result into some remote troubleshooting for devices which I don't own by myself)

     

    Best Regards, Thorsten.

  8. seqv4l clear only the controller tracks

    in MIDIbox SEQ

    Posted

    Ok, LEDs now lit according to the gatelength. :smile:

     

    I spent some more thoughts on this: actually it's better if the entire sequence is cleared with CLEAR+SEQ1 resp. CLEAR+SEQ2.

    And the GP buttons just clear the related track without hidden conventions (e.g. it wasn't obvious that GP#4 only clears PitchBend).

    In combination with a changed CC line assignment algorithm the CC Clear function finally becomes more useful:

     

       o CLEAR button now allows to clear individual tracks with the GP buttons:
     - CLEAR+SEQ1: clear entire Seq1 + configuration (*)
     - CLEAR+SEQ2: clear entire Seq2 + configuration (*)
     - CLEAR+GP1: clear note triggers (values are kept but not played)
     - CLEAR+GP2: reset velocity values to 64
     - CLEAR+GP3: reset note length values to half step
     - CLEAR+GP4: clear Track 4 (Pitchbend + last CC lines)
     - CLEAR+GP5: clear CCs of Track 5
     - CLEAR+GP6: clear CCs of Track 6
     - CLEAR+GP7: clear CCs of Track 7
     - CLEAR+GP8: clear CCs of Track 8
     Same for GP9..16 for Seq2

     (*) track configuration won't be changed if 'PasteClrAll' set to 0 in MBSEQ_GC.V4 file

   o changed the track and layer assignment algorithm for CCs in recording mode:
     Previously new CC lines were recorded into Track 4, Layer B upwards.

     Now they are assigned the following way:
     - 1st CC line is recorded into Track 5, Layer A
     - 2nd CC line is recorded into Track 6, Layer A
     - 3rd CC line is recorded into Track 7, Layer A
     - 4th CC line is recorded into Track 8, Layer A
     - 5th CC line is recorded into Track 8, Layer B
     - 6th CC line is recorded into Track 8, Layer C
     - 7th CC line is recorded into Track 8, Layer D
     - 8th CC line is recorded into Track 7, Layer B
     - 9th CC line is recorded into Track 7, Layer C
     - 10th CC line is recorded into Track 7, Layer D
     - 11th CC line is recorded into Track 6, Layer B
     - 12th CC line is recorded into Track 6, Layer C
     - 13th CC line is recorded into Track 6, Layer D
     - 14th CC line is recorded into Track 5, Layer B
     - 15th CC line is recorded into Track 5, Layer C
     - 16th CC line is recorded into Track 5, Layer D
     - 17th CC line is recorded into Track 4, Layer B
     - 18th CC line is recorded into Track 4, Layer C
     - 19th CC line is recorded into Track 4, Layer D
     Same for Track 12..16 for Seq2

     Advantage: if only a few CC lines are recorded, we've dedicated tracks
     for PitchBend and CCs (Track 4-8, Layer A) which can be individually muted
     and cleared.
     Additional CCs populate the remaining layers from Track 8 backwards, so that
     PitchBend remains an individual track if not more than 17 CC lines are recorded.

     

    The new pre-release is available at:

    http://www.ucapps.de/mios32/midibox_seq_v4l_082_pre3.zip

     

    /Update: v4l_082_pre3 provides a better Seq1/2 selection handling whenever a track is cleared

     

    Best Regards, Thorsten.

  12. AINSER problem

    in Testing/Troubleshooting

    Posted

    Well, if you see the AINSER menu item, you can already use the AINSER8 module.

    Disadvantage: one pot movement will generate 8 MIDI events instead of only 1 (because the analog input is not multiplexed).

    The 7 redundant MIDI events can be disabled by clearing all MIDI port flags (USB1..4, OUT1..4, OSC1..4)

     

    However, if you are saying, that no MIDI events are generated at all, there is either a connection or a software configuration problem.

     

    It's very difficult to support you on such an issue remotely if you are not able to use MIOS Studio; and I can't help you on Linux issues!

     

    If you would be able to use MIOS Studio, you could just follow the testing procedure under: http://www.ucapps.de/mbhp_ainser8.html

    Your observations with the ainser_jitter_mon application would make it much easier to give additional debugging hints...

     

    Best Regards, Thorsten.

  13. seqv4l clear only the controller tracks

    in MIDIbox SEQ

    Posted

    Hi Florian,

     

    somehow I already feared that this can lead to confusion: the GP button assignments are similar to the MUTE page: button #1..#8 control Seq1, and button #9..16 control Seq2 independent from the selected sequence.

     

    Advantage: direct control over both sequences without switching

    Disadvantage: unusual/inconsistent UI handling

     

    It's probably better if I decouple the UI from the actual track & layer assignments (which are inherited from the "big brother" V4):

    - button assignments in CLEAR and MUTE page shall reflect the sequence selection, starting from button #1

    - button assignments shall differ between Pitchbend and CC layers in track #4..7, which means that:

    o Button #1 clears/mutes note triggers

    o Button #2 resets velocity (mutes have same function like Button #1: no notes are played)

    o Button #3 resets note length  (mutes have same function like Button #1: no notes are played)

    o Button #4 clears/mutes the Pitchbend line
    o Button #5 clears/mutes the first recorded CC line
    o Button #6 clears/mutes the second recorded CC line
    o ...
    o Button #15 clears/mutes the 11th recorded CC line
    o Button #16 mutes the remaining CC lines in MUTE page, resp. it initializes the whole sequence & configuration in CLEAR page
     
    Do you agree, and/or do you have additional ideas?
     
    Best Regards, Thorsten.
     

  15. Song sync issue

    in MIDIbox SEQ

    Posted

    It seems that I've to re-adjust the prefetch time which ensures a proper synchronization.

     

    It's the most timing critical operation, because a lot of data has to be loaded from SD card while MIDI notes from previous patterns are played by the scheduler.

    Since the problem happens at the 7th song, it indicates that some additional FAT32 table read operations take place which cause a delay which I haven't considered yet.

     

    Could you please create a minimal session which allows me to reproduce this issue at my side for further analysis?

     

    Best Regards, Thorsten.

  16. output parameter value on dout (BCD, LED-Bar, etc)

    in MIDIbox SID

    Posted

    I looked at the code in the cs_menu.inc and i see there are quite a few steps going on to get a value and print it.

     

    and even more steps are required to implement alternative solutions, especially for somebody who has no access to the hardware extension you have in mind.

    The assembly based implementation makes it even more difficult to add extensions w/o extensive testing!

     

    So: please don't expect support from my side, there are more interesting projects in the queue :)

     

    Best Regards, Thorsten.

  17. Lemur BLM

    Posted

    TK's got me digging into the code and I must say that it is as beautiful on the inside as it is on the outside!

     

    Thanks for the compliment! :)

     

    Hopefully I will get some time to doublecheck the most recent Lemur version at my side this weekend.

  20. Fehler oder kein Fehler ?

    in Deutsch

    Posted

    In meinem Setup (_tk.asm) habe ich noch zusaetzlich ein AOUT_NG Interface aktiviert, deshalb wird mehr Speicher verbraucht und es kommt abermals zu einem Overrun.

     

    Doch eigentlich war das File nur fuer meine eigene MIDIbox FM relevant - "war", weil ich ja mittlerweile den PIC18F452 durch einen PIC18F4685 ersetzt habe, und das setup_pic18f4685_mbfm_tk.hex file verwende, so dass es keine Speicherprobleme mehr gibt, und noch weitere (sehr schoene) Features freigeschaltet werden konnten.

     

    Gruss, Thorsten.

  21. SEQV4 - Up and Running...

    in MIDIbox SEQ

    Posted

    For all the grounds on the gate jacks should I tie them all together (bus) or run seperate? Should I do the same for the cv jacks?

     

    Yes, tie them together and connect a single ground wire to a central ground terminal, e.g. at J2:Vs

     

    Best Regards, Thorsten.

  22. AINSER problem

    in Testing/Troubleshooting

    Posted

    MIDIO128 only supports the AINSER64 and not the AINSER8 module.

    So, currently it won't be possible to use the AINSER8 module properly.

    I added this to the wishlist.

     

    Once a new firmware version is available, you have to update it with MIOS Studio.

    So, use the time to find a solution for this (e.g. by booting a different Linux version, or by using a different PC)

     

    Best Regards, Thorsten.

  23. oscilator fade ins - ADSR and ASR

    in MIDIbox SID

    Posted

    Or is this simply impossible because the osc-envelopes are inside the sid and not generated by the software?

     

    Yes, (unfortunately) the OSC ADSRs are hardware implemented in the SID chip and can't be emulated via SW - this would solve many things, especially the infamous ADSR bug...

     

    Best Regards, Thorsten.

  24. Fehler oder kein Fehler ?

    in Deutsch

    Posted

    daran liegt es leider nicht, ist genau die gleiche Version, welche ich schon drauf hatte. Hab´s trotzdem nochmal versucht, leider ohne Erfolg.

     

    Hast Du es auch mit dem .hex File aus dem neuen .zip Package versucht, das ich heute generiert habe?

    Die Versionsnummer ist gleich geblieben, da sich an der Firmware selbst nichts geaendert hat.

     

     

    Ich glaube langsam, es liegt daran, wie in den MIDI-Troubleshootings ganz am Ende geschrieben wird, das mein Brennprogramm den Bootloader nicht richtig brennt und deswegen nicht alles von MIOS beschrieben werden kann.

     

    Nein, daran liegt es nicht, denn der Upload funktioniert ja.

    Dass er bei 98% abbricht hat eine andere Ursache, die mit dem neuen .hex File eigentlich behoben sein sollte.

     

    Welches .hex File aus dem Package laedst Du auf?

    Bzw. generierst Du Dir ein eigenes .hex file? (bspw. nach einer Konfigurationsaenderung?)

     

    Gruss, Thorsten.

  25. seqv4l clear only the controller tracks

    in MIDIbox SEQ

    Posted

    This is a great idea! :smile:

     

    Please try this pre-release: http://www.ucapps.de/mios32/midibox_seq_v4l_082_pre1.zip

     

    Button assignments:

       o CLEAR button now allows to clear individual tracks with the GP buttons:
     - CLEAR+GP1: clear note triggers (values are kept but not played)
     - CLEAR+GP2: reset velocity values to 64
     - CLEAR+GP3: reset note length values to half step
     - CLEAR+GP4: clear Pitchbend
     - CLEAR+GP5: clear all CCs
     - CLEAR+GP6: clear Seq1 + track configuration (*) (like before)
     - CLEAR+GP7: like GP6, could be used for other purposes in future
     - CLEAR+GP8: like GP6, could be used for other purposes in future

     Same for GP9..16 for Seq2

     (*) track configuration won't be changed if 'PasteClrAll' set to 0 in MBSEQ_GC.V4 file

     

    As long as the CLEAR button is pressed, the LEDs act as some kind of "track activity indicators" to notify the special function, and to give an oversight about the track utilization.

     

    Unfortunately the clear functions of GP#4...8 resp. GP#12..16 conflict with the activity monitor.

     

    E.g. track 4/12 not only store the pitchbender, but also the first 3 CC lines.

    Track 5..8/13..16 store the additional CC lines (4 per track).

     

    But GP button 4/12 will only clear the pitchbender (by intention), and GP button 6..8/14..16 will clear the complete sequence instead the assigned CC lines.

     

    This could be confusing, on the other hand the additional button assignments are more important than a consistent display.

     

    With some dirty patches in the seq core I could improve the activity monitor depending on how important the display capabilities are.

     

    Alternatively, I could change the recording function, so that CCs are not stored in the same track like PitchBend anymore. This would also solve an inconsistency in the mute function (which mutes PB and the first 3 CCs) - a difficult decision. 

     

    Best Regards, Thorsten.
