Don't think 100ma will be enough :(

I think JB is meant for metal to metal ...

SIDv4 x8 All the boards sharing the same ground via case??
stryd_one replied to Nestle's topic in MIDIbox SID
They're supposed to share the same ground :) This could create ground loops though, but I don't think that's going to be a problem in a digital circuit... and you could always just disconnect the ground wires between the boards . Is the outside of the case insulated from the inside? You don't really want the case to be the ground plane, think about what could happen if you accidentally touch it with the tip of your phantom powered mic cable ;) You know you can get plastic risers? -
What is the best chip test tune?/Mp3s with SIDs audio in feature?
stryd_one replied to Nestle's topic in MIDIbox SID
Thanks for the tip about rampart! Well said! I'd probably use a 6581 variant for the organ though... -
Ouch... a kit would be nice ;)

Hey dude No need for you to apologise! It's good of you to let us know though, hopefully it'll allow us to be more helpful to you :) I experience very mild AS symptoms myself, so I know the deal... There are people here with kids with AS and various forms of autism, wheelchair-bound, arthritis, blindness, bipolar, ADD, ADHD, colourblindness, dyslexia, IBS ... you name it, we have it in our membership list. So, no need to worry :)

Is OPL3 the same synth as Creative Music Synth [220]

I think this is best described using pictures... give me a while and I'll get something going :) -
DIY audio patchbay with digital routing....How hard?
stryd_one replied to Nomical's topic in Design Concepts
I have 10 AD75019 and sockets right here... If you want to alpha/beta test/contribute/etc, PM me :) -
Ahh I see what you meant now... you mean electro :) It's a bit 'happy sounding' for stryd's tastes... but it's a really unusual structure, reminds me of film score or something heh... kinda mixed with late 80's house or something. It's weird, and that's a pleasant change :)

Well, you could probably mod it to delay CC's quite easily too ;)
-
I know it is early days at the moment but.... TK do you know what pins you may use for this? I'm doing some designing right now and would like to be sure I leave room for this baby ;) I've started arranging an order of 25+ SD sockets too, so we should have enough for people to do some testing when it comes to that.

I thought that might be it.... Thanks seppo! -
no need for dice rolling, just buy another, and if it's dead, refund :)
-
that is the most ghetto midibox in ages :) Amen! I'd probably epoxy some standoffs in there for mounting...

It's either hiphop or it's not. There's no inbetween ;) Your host won't let me grab the file :(

Heya koshi, Did you do all the voltage tests before you inserted the chips? 5V is not enough power to operate the voltage regulators... Please take a look at my signature, and also follow the troubleshooting guides below my 'golden rules'. The first golden rule I'd draw your attention to, is one thing at a time... First, work on your core, without anything connected to it, then move on from there.

That's all it is (I explained how before) Like I said, the filter response would have to be just right. That depends on the patch. Try this: Open the original stereo file Upsample it to 88200 (twice the rate). Use the best interpolation available in your editor. Add ONE sample to the beginning of the right channel flip one channel and mix them together Compare that with the same thing without the one sample added. Are you getting it yet? ;) -

Of course they are, the 5B is highpass filtered by the phase difference and inversion and mixing. But the left and right channels on the original file, are essentially identical - just one of them is late. You could actually get the same file as 5B, by highpass filtering the original - if the filter response was just right. Nup, this is an entirely different effect. Such an effect you speak of is brought about by phase inversion, and there's none of that in the OPL output. Here's a project for you - try lining the sound out of that OPL card, and recording it at 96khz. Just for your own homework, but I think you'll find the effect interesting :) -
I'll let the hardware-savvy guys field that :) (I'll take a guess: the resistor sounds good) heheheh
-
Yeh you're right, there's no repetition :)
-
Depends on how sparing you are with them ;) Yes, they'll work, but too many will draw too much juice, and then nothing will work.

stryd_one replied to Green Xenon's topic in MIDIbox FM
LOL there's a big difference between disliking a synths tone, and disliking a mass of noise. The 'voice-cancelled' version is about 40% noise. That's not a matter of taste, that's just %$@#! -

stryd_one replied to Green Xenon's topic in MIDIbox FM
I'm not a n00b, I'm just working with a new audio editor, and copied the wrong channel when i paste+mixed it. It's pretty clear that they *should* be the same, there's certainly no change of phase within either channel as you suggested, just a linear delay of the left channel. -

Edited: I did this with a new audio editor and screwed up - they aren't the same on left and right at all... End edit If you think that second example from the first zip sounds "pleasant", then I think we're done here. It sounds like %$@#, it's almost more noise than signal. Forget your voice canceller, it's a proprietary device and therefore a mystery. Are you sure it's analog? an analog device doing what you suggest would have no knobs, so I wonder what setting you've used and what it really does. No need to introduce unknown variables. Just work with the waveforms in wavelab or whatever, no VST plugins or anything like that, just flip one channel and then mix them together. There's a lot of background noise on that file, was it recorded digitaly or did you pass it out of the soundcard and back in again? What else was in the signal chain? The reason I ask this, is that the only reason that the sound does not cancel out completely, is a slight phase shift (delay) of the entire waveform on one channel.... The right channel is just a little bit earlier than the left. I'll let the screencaps say it. The second one is zoomed in so you can see the level difference and it's relation to the mixed file. What you're hearing after the flip and mix, is the difference between the two channels. In the lower frequency parts of the waveform, the levels change slower, and because the channels are only slightly out of phase, there is a good chance that they will sample at the same level, so they will cancel out completely. The higher frequency portions of the sample, change amplitude faster, so there is a greater chance of them sampling at a slightly different level, so they are left behind. Essentially, it's a highpass filter. Maybe you just like the sound of PC noise and high frequencies ;) peak1.JPG peak2.JPG
