  1. The only construction issue might be noise from the crystall or digital noise from the digital lines leaking into the analog lines.

    ... so you actually want an signal router not an amp switcher... like a digital controled patch bay? If you're looking for a switcher (shortening the remote contact of an "external switch"- connector of your amp), I think there won't be any noise issues.

  2. Hello in 2005

    I have a question regarding the LC faderbanks:

    What do the faderbanks (for example: I currently see and have access to channel 1-8 and I switch to the next set of 8 faders with the "bank right"-button to 9-16) have to do with banksticks? -Nothing?

    I mean, is this a different setup which has to be stored on a bankstick in the MidiBox or does this information simply come from the host software and the Box shows this information?

    Thanks and greets

  3. Yes I understand  :)

    I don't have a layout for you but a warning. I think you'll run into a much biger problem... do the encoders and switches you'll use have exactly the same distance from your frontpanel to the PCB? This is not the case with my herdware components  :-/

  4. Thanks guys!

    I updated the pages with the transformer labels (on the PSU1 transformer is no rating readable anymore). I haven't done this earlier because I thought it's not only the transformer reliable for the power consumption but also the regulators... is that like this?

    These regulators raphael metioned are mounted on a metal plate not on PCB.

    I will dismount the supplies to check (trace the PCB tracks) about the fuses are really on the primary side.

    Thanks and greets

  5. Hello everybody

    I found 3 PSUs in 19" frames in the garbage at our studio. They came from our old interstudio communication system.

    http://home.tiscali.ch/screamingrabbit/Pages/PSU/PSU.htm

    When you electronic freeks have a look at the pics... is it possible that those are regulated PSUs I could use for my MidiBox LC?

    If so, how can I find out how much power I can suck out of them? I think the fuses on the frontpanels are on the primary side of the trafo.

  6. As I said, I'm not shure about it's possible to mount a drive inside the S3000. There is no problem to connect it external.

    If there is space and an internal connector, it won't be hard to put it there.

    You just have to set the correct SCSI IDs. - Check the manual. Specially when you connect the sampler to a SCSI board of your computer, you propably have to set the S3000 controller to slave (default is "master")

  7. It's not really fast  ;)

    Let me see in the studio, when I'm back from Holidays. I bet, I still have some old 2GB SCSI 10'000rpm drive waiting to be (ab)used.

    Perhaps you just have to remind me. Where do you live? (shipping costs)

  8. do you have any ideia about putting a zip drive inside the akai? or even a hard drive? does it already have inside a scsi connection? i'm getting tempted to open the damn thing...hehehehe..

    ... as far as I remember, you can mount a SCSI HD drive inside. I'm using the external connection and have it connected to a 1U 19" framed CDR and ZIP (both SCSI).

    I think the SCSi interface was a standart feature on the S3000XL.

  9. i just want to know if it's possible to send a sysex string or midi each time a button is pressed ,even with the gp or play and pause etc buttons?

    ... should be possible. I'm mostly only concerned with the MidiBox LC... so somebody else, more experienced possibly will answer you this question.

    And can i use the 1GB drive in the notebook to store data ,to avoid the use of bankstick?

    ... you could upload the data from your drive with sysex... I think the bankstick is much quicker and the way to go.

    And just a reminder: You better use a LCD anyway... for debuging.

  10. but don't most touch pads have two variable resistance lines that could be properly scaled and read by an AIN?

    1. The question is, how high is the max resistance?

    http://www.midibox.org/cgi-bin/yabb/YaBB.cgi?board=parts_q;action=display;num=1103305075

    recommented impedance for the ADC suggested in the PIC18F datasheet. 1k..10k

    ... or could that be done with an appropriate resistor connected in parallel and then just scale MIOS to this range?

    2. When implemented in MIOS like a potentiometer, the physical touch position would be absolute (means: the controller value would jump to this position). To replace a motorized joystick, the touch position should be relative to the current parameter value.

    3. Since I think that a regular laptop pad would be to small for surround control device, would a touch screen (resistive type) work? They're available pretta cheap.

    Perhaps this could be programmed when working with the AIN...?
