  2. Sync Unit AU (plugin generates dinsync over audio)

    in Miscellaneous

    Posted

    thanks for the kind words (me , a clever idea  ??? :-[ ;) )

    actually I was inspired by a lot of people who have done similar things the past few years, but with samples of pulses.

    I was amazed too that nobody did this earlier.

    Do you think that a mode would be possible which sends a different clock pulse level for the Start signal?

    (I consider to write a MIDIbox application which generates a MIDI clock/start from the audio signal)

    i dont know exactly what you mean

    someone is designing a circuit for me using schmitt triggers, I'll make a special mode for it in my software. should work with a mono cable, it will have a high rate clock over the run signal for ac coupled start/stop detection. Is that what you mean?

    Would higher resolutions like 192ppqn and 384ppqn be possible as well?

    Yeah, am planning to implement that as soon as I figure out how the gui stuff works for Audio Units.. I'm really a n00b in Audio Unit development. All I can program so far is sliders and I dont need any :) You can already see the dropdown menu in the mockup of the gui posted above.

    Things like that are pretty easy to impelemnt, but right now I'm using synthesis and I wonder if it will work correctly when using a lot of cpu.

    Maybe I should consider wavetables, I'm not sure.

    It will work but I don't have anything to test the consistency with.

    It should be pretty easy to generate midi clock too from those pulses

    And would it be possible to add an optional negative delay?

    This would allow to compensate the latency if the audio of the synched device is sampled by the DAW and forwarded to the Aux bus.

    possible, yes, but most DAW's support this feature somehow, eg. ableton live has seperate track delay ( + and - in ms).

    I delayed it a bit last time because everything sounded too tight with ableton when I check the demo yesterday.

    I also still have to check if the polarity of my signal is right, that could vary half a clock pulse. And I'm not sure if dinsync needs a rising edge or a falling edge, etc.. I'm just glad it appears to work fine and that you can actually hear the difference

    Anyhow, this is how you hook up the cable: http://users.telenet.be/darffader/rv0/syncable.gif

    (hope i got it right now, I made a mistake in the release notes, just corrected it..I made my cable 3 months ago (edit: I just checked, it appears I have already tested it using samples in March) and wrote it down wrong I guess, hope nobody started soldering already lol)

  3. Sync Unit AU (plugin generates dinsync over audio)

    in Miscellaneous

    Posted

    Everyone who has tried to synchronise old Roland dinsync gear with computers must have noticed you get a really sloppy synchronisation.

    It has driven me (and many others) crazy over the years. Even with the best software, midi hardware and dinsync converters, the results are 'sloppy' compared to hardware clock. Tests have shown it cannot work reliably, ever, with 10ms deviations measured.

    I've been researching pc to hardware syncronisation methods over the past few months and now I have released the first version of an Audio Unit plugin.

    For now you need a MOTU soundcard and a dinsync slave device, but other methods of syncronisation are being implemented.

    A diy electronics project is being developped and will hopefully be ready before the end of September. It will allow you to use any computer audio output and get dinsync from it, fully latency compensated by the DAW.

    Other sync options will be available as soon as I've written a gui for it. Think FSK tape sync (korg kms-30), pulsed tape sync (mpc electronics uk - sync track), 48pqnn korg dinsync, etc... you name it, it can probably be synced.

    If anyone would like to test, I uploaded Sync Unit AU version 0.5 yesterday.

    It doesn't have a gui and only does Roland din sync for now.

    Seems to work fine in Logic 8 and Ableton Live 8. Haven't tested with anything else yet. It's already very usable, and sounds very tight.

    Download it here

    ----------------------------------

    Please read the release notes before causing damage.

    Future features will include shuffle modes. Windows VSTi and maybe RTAS should follow when the AU is finished.

    See attached image for a mockup of the GUI in development:

    I'm really curious about user experiences with this software.

    a small fragment of one of my first tracks, made on playstation's music when I was 14 or something. It got featured on Future Music (the Dutch version, not the UK version) with a really promising review (although the track really wasn't that special)

    dj chillswitch - dungeon

    afterwards i got myself some Korg Electribes, a TR505 and an alpha juno, recording stuff like that (beware, 4/4 techno/acid/stuff)

    poq - emocore

    during those days i made some ambient/idm stuff under another alter ego. don't have the earliest tracks online but some are here: darf fader (farewell is quite good)

    Finally I ended up with the "rvooh" name, with TB303's, hardware sequencer.. That was my first track (2003) rvooh - moon note

    And yet you're happy to replace with chips you know will fail in time?

    hehe sure, I got them free and now the chips are socketted so I can put in a clone some day when I can afford sustainability.

    I'd just not recommend this for people taking their Juno's along for live gigs.

    But given that they're removing components which have already failed, what's to lose?

    not much more but time. and maybe if you don't let it dry out well, your faders.

    Acetone is a solvent, and evaporates very very easily.

    i knew that.

    i need to be exposed to air though to evaporate.

    If it soaks inside a material, it needs time to "come out of it"

    If you "washed" your synth in it, sure, it will wash away the lubrication in the faders and they will feel a bit ratty with no grease in them.. Not sure what you mean about eating the traces, but acetone doesn't do much to copper traces on a PCB.

    I mean the traces in the fader. Not the lubrication. Not the PCB traces.

    sing some form of scare tactic to avoid people trying a possible fix (Hell, the chip is coming out, so you might as well try the $2 solution) bugs me.

    he's not using this scare tactic anywhere. I confronted him with the acetone method and after research and unsuccesful tests he added that it might be dangerous for the faders in your synth. He hasn't commented on any of those acetone topics officially.

    If there's anyone using this "scare tactic" it would be me. But the only thing I'm doing is warning people and advising them to dry the chips for days in direct sunlight before replacing them.

    Hell, I don't use his clones myself, I sourced some original voices for free for mine and they still work fine. However I'll never do the acetone trick as I just dont trust it will continue to work over time.

    yeah whatever.

    laugh all you want. everyone does when they hear this.. I hope your scientific knowledge greatly exceeds his, yet I doubt it. Makes you wonder why smart people like you haven't made a clone up to the quality of what he has built. And why every other voice clone chip behaves totally different (and sounds different) and is pure fraud?

    At least try an effort at understanding.

    I would explain it better if my english were a bit better, right now I can't really do better than "it will come loose inside your synth". Sorry about that. But I wouldn't be suprised.

    I guess Acetone soaks really deep into materials like the chip coating and than gradually evaporates over time (because it's not directly in contact anymore with air). The damp coming out of it, how small it is, could easy eat the traces of your faders.

    Just like spraying contact spray on one side of a synth could in time ruin all the faders and/or other components?

    Done laughing? I'm done explaining.

    What I think is way more funny, is that you could magically fix a chip by soaking it in a solvent. Alright there could be something thermodynamic going on in the reaction that would cause the pcb to increase/decrease in size (and thus maybe fixing any broken traces, but that's not really the problem with most of these broken voices).

    Some say that the original voices run too hot, but that's also BS.

    There seems to be more than one failure reasons for the original voices, and the clone builder has been studying and fixing them for years. Starting off with a VCA only clone in 2003, because with some voices it's only the VCA that fails. You can read that on his old site

    So far, NOBODY that I know who has tried the acetone method has done so in succes. (and i've been also following some forumthreads about it)

    Although I have read quite a few positive experiences from people I don't know (youtube comments).

    So yeah. If someone would like to try it, please do and post back your experience, but keep in mind the residu story alright?

    i know the creator of the voiceclones quite well http://www.analoguerenaissance.com/D80017/

    These are the only clones you can trust AFAIK

    all the other clones are rediculous and sound different.

    he told me the acetone method doesn't really make sense, tried it on a few chips, didn't work, could have lots of dangers: acetone soaks in plastic and remains there (the surface will evaporate), after a while it will come loose inside the synth, killing all your fader traces.

  13. Has anyone thought of an "MBHP-303" clone?

    in Design Concepts

    Posted

    Sorry for the bump! But I just read thru the whole thread.

    Instead of making another 303, why not focus on making "the next" 303? (Just a thought)

    Exactly, I couldn't agree more.

    What frustrates me most on every clone that exists is the fact that they try to re-invent the sequencer. Ok, I agree that the original sequencer has a few drawbacks, but the way it's done on clones has a lot of drawbacks that weren't originally there.

    I was checking the x0xb0x system, because I actually would want to rewrite/redesign it so the sequencer and layout is 100% the same as the original (with additional features of course).

    I think it is sad that the x0x doesn't provide all functionality (although Sokkos is really great).

    I came to the conclusion I don't really need the x0xb0x project, and might as well start from scratch (because the sequencer code is "wrong" anyway). Soundwise, it doesn't matter to me all that much.

    The main thing is the sequencer, so I was thinking about the MBHP. As I have never - ever - checked any midibox sequencer sourcecode, I don't know how easy it would be to implement.

    I'd like to have some of your opinions!

    To sum it up for those who don't know, a 303 pattern has the following things:

    Pitch Mode & Time Mode.

    pitch mode is just an array of notes (actually it's a cyclic list, but I haven't figured out why yet) and some note effects (up, down, slide, accent)

    time mode contains only time information, thus the amount of steps, and the value per step (note-on, note-extend, rest)

    But there's more to it than that. I'd would be cool to replicate this behavior (and all the other coolness) to drive sids, x0xb0xes or just about anything you want.

    ... but the price for this pretty common knob is not very common! - That's fu...g cheep for a collet knob.

    exactly

    and the store says it will go cheaper on large amounts.

    CME chose nice knobs for sure....

    indeed.

    made in china.. i've been checking alibaba.com but no luck so far.

    there's way cheaper on the same site of course..

    but not very special colors/not that bright/not that readable..

    if i'd be ordering from crystalfontz and add up tax, postage, customs, it would amount to the same sum i guess.

    ofcourse, i'm just checking around, as I'm ordering things from farnell anyway.
