Version 1.1 now available!

I'm happy to report that DSX Hack version 1.1 is now available! There are two important improvements in this release:

* Changed Send to CV Outputs to be a per-Track setting, and not a Global one
* Fixed a bug in which long Tracks (greater than 280 notes) were not being successfully sent to the DSX

Enjoy!

  • Woho!!! Yes!!!

    I'll try it out ASAP! :)

    Thank you very much Daniel!!!!
  • Silly question. I was wondering if DSX hack can be used for regular OB synth use along side CV use. Meaning, can I use the program to input sequences/noted to be played back on my OB-8? the reason I ask is inputing everything via OB-8 can sometimes be inconsistent or unreliable.

  • Yes - you can specify whether or not the note information is sent out to the CV outputs, or to the connected Oberheim synth (and as noted above, the most recent version allows this to be done on a per-Track basis, as opposed to globally in the original 1.0 version).
  • Best thing to do is try the demo version to be sure it does what you hope to do... It's a crippled version in that it doesn't allow Merges and only 4 notes on one Track, but it will let you see if the workflow you're looking for is supported.
  • I will probably buy it no matter what. The fact that it's not limited to CV use is spectacular... but I was pretty sure even if it was that after dumping the data one could always switch the track out of CV mode.

  • One last question. My DSX is one of the last production models with all the "updates". It has the last version of the board and midi holes (unused) punched in the back. comparing this to another I had the boards were different. any chances of mine being unsupported. These things are quirky indeed. And secondly. I've notcied that the CV out on my DSX is WAY out of calibration for scale and tune. Do you know a good person to have this calibrated repaired? I assume without an OB to test it with It might be hard to get it working right.
  • Yes - you can always convert a track from CV to Obi or vice-versa on the DSX itself.
  • No idea re: whether your model would be unsupported (never heard of one with punch outs for MIDI?), but my guess would be that if it's using v3.x software, it should work fine. Again, try the demo first to be sure.

    Re: calibration - you probably don't need a tech. There's two trimmers on the inside to adjust the octave range and the offset (not sure if those are the technical terms, but that's how I think of them). This reminds me that I was going to write a post with pictures about it, but I never got to it... Will try to when I have time.
  • Yeah, I fiddled with the trims a bit and couldn't even get it close. I need to sit down with the service manual and go over it in earnest.
  • You know what - I never really noticed before - mine has the same punch outs now that I look!
  • Re: the trimmers - I used a digital voltmeter (nothing fancy), and measured voltages when programming specific notes (a series of "C"s). Each octave should bring you up 1 volt, with the bottom C at 0 volts.
  • First adjust the trimmer that adjusts the octave range - for each octave jump, you should see a 1 volt increase. Then adjust the offset trimmer so that C's fall on 0, 1, 2, 3, etc.. volts. You may need to repeat the above process iteratively to get it perfect.
  • Hi Daniel,
    I just hade the chance to test things out with the new 1.1 version and I've discovered that multiple voices (polyphonic) assigned to one track OBXa doesn't work.
    Instead the play one note at a time with last note priority.
    Also the tempo doesn't seem to be written to track 0 on the DSX (it just play the tempo set by the DSX itself).

    Have you had a chance to test 1.1 it against an OBxx synth?

    Kind regards
    Peter
  • Hi Peter,

    I don't have the ability to test against an OBxx synth, as I don't own one.

    With regards to the tempo being written to Track 0, in my experience there are times where for some reason when loading from cassette, the tempo information is not read. As a test, try completely clearing your DSX of all sequence info - Press Edit, then 4, then Erase. Then try and send the info from DSX Hack again. Also be sure that the DSX is set to "listen to" Track 0 once transferred from DSX Hack. I'm not in front of the DSX now, so don't remember the exact keypresses, but hopefully you know what I mean.

    Finally, for the polyphonic question - can you help me by sending me a cassette dump from the DSX *that was programmed from your OB-Xa*, of just two notes that are played together (polyphonically), so I can see what that cassette dump looks like? Maybe there's something I'm messing up when dealing with non-CV outputs....

  • Hi Dan,

    I tried the "clear all sequences" trick yesterday but that didn't work either for some reason. The tempo per sequence (track 0) would be great to have if you merge several sequences with tempo changes together.

    I'll dump a OB-Xa polyphonic sequence for you tonight, to which email address?
  • Are you sure that you have Track 0 set to ON on the SELECT PLAY TRKS page?

    Please send the dump to dan@defectiverecords.com . The sequence should be as simple as possible, ideally like just two notes held down at the same time.
  • Hi Dan,

    I've just emailed you two different dumps of OB-Xa recorded Poly Sequences.

    BTW I got the tempo on Track 0 to work.
    Obviously you have to select another sequence first (even if that specific sequence is empty) and then select the sequence you want to play for the tempo to show up fine and play at the correct speed. The DSX acts that way on its own...it has nothing to do with the DSX Hack...so don't bother to investigate that further :-)

    /Peter
  • Perfect, thanks Peter - I received the dumps. Won't have time to look till probably the weekend, but will report back to you.

    And cool on the Track 0 stuff, glad you got it sorted!
  • Apologies for the long delay - I finally had a chance to look at and decode the files you sent Peter. Thank you, they were helpful.

    The bottom line is that I realized that I didn't build DSX Hack in a way that supports polyphonic MIDI files! This is probably because I was so focused on thinking about CV output situations, rather than thinking about an OB keyboard that was directly connected.... And that CV-based connections by definition will always require monophonic...

    Ugh - I will have to think about how to deal with this, not going to be pretty. For example, DSX Hack would need to understand how to deal with situations like this: source MIDI file has note information on one MIDI channel, and on that channel, has up to 3 voice polyphony in some sections. But what if the user has selected only one or two Voices for that MIDI channel in DSX Hack? The app will therefore need to gracefully deal with dropping one note of polyphony...

    Like I said, will have to ponder this all for a while. At any rate, I apologize that you are correct in your assessment - the current version of the software won't accommodate polyphony correctly. :-(
  • Ok, I understand.
    No worries, I can still use my OBXa to record polyphonic tracks :smile:
