    Hi Pascal

    I'm not an electronic crack but what you write, sounds logical to be and could me a problem.

    Optical (I already took two mices out of the technical garbage at our studios  ;)) I like because there is no friction (aging). You're right, that the feel could be achieved with bearings on the wheel shaft and a heavy enough material for the wheel. Fairlight uses a piece of piano damping fabric (propably the wrong expression) which is pressed on to the shaft by a spring loaded screw.

  2. Steuern mit Midi

    ... nun wenn Du ein bestehendes Setup möchtest, welches Du in Dein Wah implementieren kannst, könntest Du ein Motor-Fader nehmen. Ich bezweifle jedoch, dass Dein Wah-Poti gerade 10k-Ohm hat. Von einem bestehenden System (automatisiertes Wah), welches "ready to build" ist, weiss ich nichts. Deine Ahnung von Elektonik kannst Du hier vergrössern. Ich bin schon einige Monate im Forum (wusste auch nicht viel von Elektronik... nur Grundkenntnisse) und lerne durchs Lesen anderer Probleme ständig dazu. Jetzt starte ich bald mein eigenes Projekt und was ich bis jetzt erfuhr, sind alle Leute hier sehr hilfsbereit und daran interessiert, einem zu helfen. - Just go for it und lese Dich durch die Forum-History.

    Have you thought about a pager-type device that vibrates with overload?

    Good Idea... I think for the overloads a piezo beeper would be o.k. too, since this shouldn't happen to many times. I have to ask her, about a "beep" is enough or about she should get information, on which track it happend. If she should get the track information, a speech processor or a Max/MSP patch would be a good idea again.

    For the level information I think a resolution with a fader would be to precise.

    Like Moebius wrote in his first post:

    Your radio stations "master limiter" will anyway fuck up any dynamics on the material

    ... we have a processing unit on every program, thought we don't drive it as hard as he thought. I think something like 7 steps would be enough and solenoids (thx Moebius) would come in handy again:

    - OL (for example: beeper)

    - +9dB

    - +6dB

    - +3dB

    -   0dB

    -  -3dB

    -  -6dB (and lower)

    We use DIN metering which means: 0dB (+6dBU) eq. -9dBFS with 10dB/Sek. weighting on level deminishing (sorry... pretty hard for me to explain in english  :-[)

    When the indicator shows her for example +6dB, this could be anything between -3 and -1dBFS. If the FS level goes down to between -4 and -6dBFS, the +3dB indicater would get active... and so on (her target level for the speech program she's producing is 0dB DIN). I think this would be precise enough and the mastering processor would do the rest. The steps even would come close to the weighting algorithm of the DIN scale. When I drive a spoken file at 0dB DIN it's fluttering at -7dB on the FS scale.

    Thanks again for all this brain smoking  ;D

    Thanks Smash and Moebius

    I didn't want to use "speak" since on the platform  a JAWS application is running which tells her the content of popups or windows status, so it could get pretty messy since she has to cut and mix audio as well.

    Currently she uses one soundcard for all but I will change it, so the JAWS comments come from the internal soundcard with just one speaker in the middle and the produced audio comes from the Digigram VX card in Stereo LR. This way her mono parts come from LR which builds a phantom center position and the JAWS stuff really comes from the center. With that her brain will be able to better distinguisch the two different signals.

    But I didn't think about a request button... good idea Smash!

    I also like the servo thing... something like an index on a watch.

    Would it be possible to smooth (kind like weight) the level signal in MIOS so the index wouldn't flutter that much?

    For driving the servo I'd have to use an Analog Out, right? Is this possible on the same core with 8 MFs or would it need a additional core? (An additional core wouldn't be a financial problem since I have about $8000 budget for hardware)

    Regards, Roger

    She has more than "sensible enough" ears, I think?

    ... not sensible enough to tell absolute level, but shurely sensible to hear relative level (differences).

    Your radio stations "master limiter" will anyway fuck up any dynamics on the material, let it be 32bit or analogue tape, let it be -3dB peak or -30dB peak...

    ... we're not an american style Hit-Radio station who's attitude is: "We have to be the loudest". We have 6 programs and only 2 of them are heavy compressed. On the other ones, we have from classical music to radio dramas with pretty much dynamics. And the master limiter processer has 150 bands and there for it is pretty important, that the audio material has the right level, otherwise it doesn't work the way we programmed it for.

    About clipping: Even for a visual disabled person it's not possible to hear, when 10 samples are over 0dBFS. But she should be warned just as we audio engineers like to be warned, when we can't hear a clipping but the OL-LED shows us one.

    ... but thanks for your reply anyway!

    Thanks Jack. I was thinking about something like that too. Almost like a braille module working with piezos. When I'd take the regular signal like for the LEDs, I think it would get pretty noisy. And how could I build that by myself? A spare braille module with 6 pins costs about $200  :-/

    Actually I'm thinking all my spare time about the MidiBox LC of my dreams I'd like to build for my personal studio.

    Yesterday I had the first meeting for a project my employee threw me in.

    I have to make a concept for a Digital Audio Workstation for a visually disabled woman who works at the same radio station I do, as a journalist for bachground storries and she has to cut her audio by herself.

    I will take "Sequoia" www.samplitude.defor editing since it is possible to integrate it in DIGAS which is our Audio database manager software. Sequoia is supporting the Mackie protocol and all the editing is controllable by keyboard shortcuts which I will set on a programmable key matrix www.x-keys.com. The controllable keys are labled by braille letters (for touch reading with her fingers).

    With the motorized faders of the MidiBox LC I'd like to build for her, she will be able to touch feel the current position of the level fader.

    And now the big question:

    I would apprechiate every idea about how I could make it possible, that the software  can tell her the current level metering position. It could be a average metering and also peaks / overloads should be displayed.

    Greets and thanks for ideas and help

    I'm getting more and more interrested in this stepper motor thing. "Fx3_hdrive" opened a thread on that a while ago.

    Does anybody experienced the feel of a Fairlight MFX Jog-wheel yet? It's smooth, is easy to turn but still got some resistance or mass. I could imagine that a stepper motor gives a nice feel with it's perfect fit with bearings. If the output voltage at low speed is a problem, you could change transmission when you drive it over a tooth belt (is that the right expression? In gerrman: Zahnriemen)

  15. Panasonic faders and touch idea

    in Parts Questions

    I think you can't work like this. It would activate touch write not controllable enough. Every time you get to close to the fader, it would overwrite your present automation track. - But just go on, letting your ideas out. A lot of inventions came out this way in the world!  :)
