  1. It seems to me that you could achieve this by using a switch that can record the first depression of the key, then the release of the key, sending a signal both times.

    This isn't how velocity sensitivity works. Keyboards have 2 switches per key, a known distance apart that are pressed one after the other. The time difference between the 2 switches being triggered is used to calculate the velocity, which is sent as the second byte of a MIDI Note-on message. When you release the key, the keyboard detects this and sends a MIDI Note-off.

  2. The way I'd do it re: the keyboard is to get a cheapy MIDI KB, something like an old Evolution one. I've got a Commodore branded one made by Evolution that would be perfect and no, you can't have it :-P. The keys are a little undersized admittedly but it's lightweight and easy to rip apart.

  3. I've looked briefly into stuff like this before now, and so far I've not found an easy way to turn a standard such as VGA or DVI into a vendor-specific LVDS interface - much less so a fairly old, low-res analogue standard such as S-Video. I'll be the first to admit that my research hasn't exactly been exhaustive but it looks like you're in for a hell of a lot of work.

    That said, if you figure it out I'd love to see it!

  4. I can't help you with your DC/AC woes, but if you're in the market for a new reverb I can recommend the Line6 Verbzilla, provided your setup allows you to use guitar effects. I picked one up a while back off a friend who was selling his music gear off and as far as I'm concerned it's the most versatile reverb I've ever used. Plus, it runs off 9VDC the same as pretty much every other guitar pedal - even a 9V battery.

  5. small enough to use in a dorm room

    I know that students tend to have some weird stuff in their dorm rooms, but I don't think I ever saw anyone with a CAD/CAM station next to the bongs and pyramids of beer cans...

  6. I got a reply in my email about this petition today:

    We are pleased to tell you that there is no truth in claims that the Government is planning to introduce a requirement for entertainment venues to fit noise control devices.

    Each Local Authority Licensing Authority considers every live music application on its merits, and decisions are made entirely by them.  However, the Licensing Act 2003 does not allow mandatory conditions for live music to be imposed across the board.  It would not be possible to impose such a condition without a change in the law and such a change is not, and never has been, on the Government’s agenda.

    There is also no legal requirement under health and safety legislation for entertainment venues to have noise control devices fitted, nor is there any proposal.

    The Government is acutely aware of the contribution that music makes to our culture and we remain committed to a vibrant and flourishing creative sector, of which live music plays an essential part.

  7. HCl is hydrochloric acid. I know schools use it quite a bit (or at least, the one I work at does) so it should be fairly widely available in various quantities and strengths. A Google search for "chemical suppliers", "lab suppliers" or similar should yield some results.


  8. I'm not too hot on this one myself, but I think the people you need to speak to are the Mechanical Copyright Protection Society / Performing Rights Society (

    ++++ EDIT: ++++

    Yeah, thought so:

    Any music which is played outside the domestic or home life is regarded as a public performance.  The Copyright Designs and Patents Act 1988 means that if you use copyright music in public to lawfully do so you require the permission of the copyright owner for every piece of music that is being performed.


  9. ...switching to DSP on a pc that there is some unwanted latency...

    It looks like you just do the programming on a PC, then load your program onto it via USB in much the same way as you can write MidiBox code and upload it over Midi. Since Line6 talk about lending the pedal to others, I think it's safe to assume you don't need it connected to a PC to work it.

    Either way, it sounds like a cool idea - I like their ToneCore stuff and the idea of programming one myself sounds awesome. Only problem is that I don't have $200 kicking around  :-[

  10. I picked up  a couple of 10Mbit 1U hubs/switches this week for £5. They have nice internal power supplies if needed, and can be 'repanelled' with some alloy. I was lucky, they we on their way to the skip

    That's exactly what I'm doing with mine (if the bulk-order goes to a second round). We recently disposed of some old IT gear at work, including a couple of Planet Ethernet (urgh) 24-port switches in nice shallow 1U cases. As soon as i saw it I thought "GM5".

    I'm thinking of bodging up a simple MIDI activity light system, (probably pulse stretchers based around 4069s). Is this of interest, and are separate in and out lights best?

    Activity lights sound pretty useful to me - especially one pair of I/O lights per port.

  11. Es uno cloudio!

    Uno cloudio?

    Si, uno cloudio!

    Ay ay ay! <serious> Reporto especial - uno cloudio.

    /Cuts to images of panic, old women praying in the streets etc.

    With thanks to the Fast Show, and apologies to any spaniards out there.

  12. OK, this is just embarrassing. After a couple hours messing with soundcard settings, wading through the XP-10's awful menu system while constantly repeating "It's gotta be something weird with this new keyboard" and looking for the magic menu setting "make things work" I look under my desk and what do I see?

    A 15-pin D-sub plug.

    Like the kind that should really be connected to my soundcard.  :-[

    I swear, some days it's just not even worth getting up in the morning.

    Thanks S1, Goblinz - I know the question was pretty damn stupid to begin with, looking back. Not as stupid as I bloody feel now tho  ;D

  13. Hi All,

    I recently acquired a Roland XP-10 that I'm trying to get talking to my computer. I've hooked it up to the MIDI cables from my soundblaster (I know, I know...) gameport, turned off Midi Local on the XP-10 just like it says to in the manual, and... nothing. I've got no midi going into the PC, and when I send stuff from Midi-Ox the XP-10 gives no response. Has anyone on here come across anything similar? I'm pretty certain that it's not a problem with my PC, since my old keyboard controller (an ancient Evolution branded as a Commodore) worked fine and the only thing I've changed is the keyboard.
