Well, nobody has ever rapped to it. I thought maybe someone would give it some use. But, just like so many tracks in need, this one doesn't get the love and support it needs.I guess it'll go back to the foster home for unwanted tracks.
I LOLed.
Maybe your 1P and 2P controller inputs were switched? That would explain not being able to use NTRQ but still being able to start a game of CC.
jean michel jarre prodigy?
I dunno, it's pretty, but it's not a very good instrument. Limited range, difficult to play fast, and inexpressive. Maybe if the height at which you interrupted the lazer could be detected and assigned to a parameter, we'd be getting somewhere.
Yeah, considering the fact that it's being played at a Theremin Hero event, you'd expect it to be a more expressive instrument.
Did this collab recently. Audio is crap because I didn't take the time to make a direct recording off the board but I'll do that soon.
Any thoughts aside from "Dude, close your mouth"?
Edit: This probably belongs in the collab section, where I thought I was posting.
Check the power supply. I had an issue with no sound and the AC fuse blew in the PSU. Replaced the fuse and all was well.
Edit: how was the other chip "partially" working?
One voice worked, the other two did not. Filters did not work.
It's a common issue.
Have you checked the PN2222 NPN amp transistor?
And are you testing the audio through the RF connection or a line-out?
Line-out. And no, I haven't check the amp transistor yet. I'll do so now, but I doubt it'll be either of those things. If it was a problem with those things, it would be affecting both chips. Which it's not.
EDIT: Can't seem to get it going yet. I'm going to give up for the night cause I've got a bunch of work to finish. Thanks for the help.
yeah sorry about those scratches, fumbling :x
A dead chip should always get power!
That's what's confusing me. My other half-dead chip still emits that video noise when the video is turned on, but this chip makes no noise at all. I tried cleaning off the pins & and socket but that's made no difference.
Yeah, I've seen that guide before but it doesn't really mention audio problems of this sort. Aside from saying "If you have no audio, check the 6581 chip."
I had previously changed several caps, but I checked those just now and they're all working.
It seems to me like the chip isn't getting power at all. It emits no sound and doesn't get warm. However, there doesn't appear to be any damage to any pins. Aside from some cosmetic scratches on the bottom of the chip it looks perfectly fine. So I'm still muddling through what it could be.
That chip I sent you should be fully working, I put it in a 6581 machine to test before I decided to fry it's ram chip.
Take a look at the internal fuse, it might be blown.
Checked that, yeah. It still works with the other chip, even after several tests with the new chip. So I'm not sure what it could be.
So, I recently bought a 6581 from CMDR. Upon arrival I switched out the partially working chip with the new one but I've yet to get it working in any way. Before assuming that it's a totally bum chip, I thought I'd ask here what else it could be.
The thing that strikes me as a little odd is that the new chip makes absolutely no sound at all. Even the background noise is completely gone. Even my previous chip, with it's barely functioning one voice, would make a bit of noise when the computer was on (especially if video was turned on in Cynthcart).
Any ideas?
Got it today, but it's non-functioning. I tried it on two C64s, both of which worked with other chips but got absolutely no sound with the chip you sent.
Not sure what it could be but if it helps anyone diagnose it I'm not even getting the normal background noise that the functioning or partially functioning chips make. It's the same lack of noise you get when you try to boot with no SID chip at all.
Seeing if anyone here might know what's wrong:
Do you have any audio samples of the unit in use?
Just saw that this can use .XI format instruments! That one fact has convinced me to try it out.
Yeah, I could see the being a real possibility in the future. I really don't think it would be too expensive, because all it would need is the voltage divider, the FPGA and whatever chip he's using for he buffer. There really isn't all that much else needed. It's also nice that you can do it without removing or adversely affecting the game boy's screen. So, in theory, you could add a video out socket to your game boy that would go to the VGA converter device.
