I miss it when MySpace was cool.
You mean when they launched and just copied friendster without the taxing code of the 5 degrees of separation feature?
Myspace was never cool, it was just the only site able to handle the load because of lack of features and gross fundage.

Not a bad idea, a stickied "new member? introduce yourself" thread in general discussion.
after the horrible new layout was done and the goddamn black eyed peas invaded the site with their new rad "8-bit" personas i knew i had to leave.
Just a fyi the "8bit" black eyed peas look is actually not trying to be pixel art, its *suppose* to be a lego mosaic. Not that I'm a fan or anything.
muddygb, mgb, pounder...
Just to be clear mGB aka midiGB, will overwrite your save memory. or at least some of it. mGB supports presets.
It's mono but you cant really tell, the drum samples are tiny. 4bit sample player & sample osc & pwm synthesizer with filter... I'll be releasing the code at some point, once its working nice.
I made a simple kaosspad app (still in development) I stopped because I wanted stereo input via ipad usb external soundcard, and there have been some problems.
Filtatron is pretty good, there is also reactable which has audio input capabilities, its quite nice.
Personally I dont like the quality of pwm as dac. but that is due to aliasing on high notes. which wouldnt be a problem if you did some interpolation magic. but, that is kind of hard on the arduino due to processer intensity. I would imagine this same problem exists with using a external dac as well. Unless you're running at a very high sample rate (well above 44.1khz)
I use a r2r dac and run the interrupt at the proper rate to create pitch, which restricts it to monophonic and uses 4 pins for 4bit.
Lame restriction but the quality is quite nice for notes- pure 4bit oscillator- no aliasing, no lowpass filter to kill the high pitch tone generated by the pwm at the frequency of the sample rate.
Just looked at the two Play it Loud DMGs I have with me and they are both DMG-PCU-08
Maybe the Grey boys with 01-02 are the first years of production models?
The play it loud gameboys came along quite a bit later. Also they have those cheapo blob chips- though I am pretty sure there is absolutely no audible difference because of that, its just cheaper to manufacture.
About Japan DMGs, I have 2 of the "rare" white ones, and both have later reversions. Just FYI
35 an hour? Really?
1: LAX is like a 1.2 hur drive. 2: im currently sick.
I think the best suggestion so far would be to just have a key combo that would put PR8 into slave mode and the screen (and screen updates) would get turned off then the code can just sit in a background loop waiting for sync/triggers until you press another (same) key combo to kick it out of slave mode and back into the editor.
It would probably be safe to assume this would work but on the other hand it would be a shame as it would be so good to be able to still edit parameters in PR8 as it's playing.
So thre is no other port that is accessible in any way? Whats on that little pin out on the bottom of the nes?
As a minor point, midi output from a PC does in fact exhibit jitter, and usb ones are often the worst kind-
See e.g.
this forum thread
Just so you know I hate gearslutz. its like 90% of the people there just like to pretend they know what they are talking about.
*edit *
Yeah, line noise != jitter. God I hate that place hehe.
And yes we are pretty much talking the same, I was just being uber clear cause I hate when people bitch about MIDI being lame because it has a "delay" ... When really 98% of the time, if you hear a delay, its not MIDI, its the setup. 
i wasn't recommending sync24 because it's retro... it's reliable and very much still used by a lot of electronic musicians.
It's a starting point to do a proof of concept w/ analog clock since one can easily make a 555 clock to proof it if responds as it should.
From there the timing can easily be switched over to midi clock if so desired. but i think having both analog clock and midi clock will be a must
in the end.
Input is up to the hardware that connects to the port. So to me it's a nonissue. it's really about getting a accurate timing input. If we are using the joypad at 60hz, the only reliable timing would be having a timing from the sequencer at a rate devisable of 60hz- at least on paper- unless I'm missing something.
(PC MIDI Interface Jitter can easily be 10ms) + (midi-pulse-converter Jitter if any) + (+/- half of 1/60 s jitter, is what about 8ms) = ??
[technical rant]
PC Midi shouldnt have jitter, Some audio / midi programs add delay to the midi out to match the latency of the audio signal. Most of the nice apps have options for changing this- Like ableton live.
Midi should have a delay anywhere from 0 to 3-5 ms maybe. Being that its 31250bps and 10 bits per byte. (start bit + 8 bits + stop bit) a sync message is just 1 byte. If all you are sending is clock tick, the latency would be 3 ticks per ms. This of course doesn't account for computer driver & software latency, but I usually get around 2ms. - Yes I actually check this when I'm programming with sync/midi data.
[/technical rant]
Anyway, 120bpm breakdown:
- 24ppq: 48hz .... (120*24) / 60
- 32nd notes: 16hz .... (120 * 8) / 60
- 16th notes: 8hz .... (120 * 4) / 60
- 8th notes: 4hz .... (120 * 2) / 60
Anyway I guarantee you that without a proper interrupt or something triggering in time, the timing will be wonky / loose. At least with my experience- Maybe I suck.
As far as sync24/midi sync etc, its all the same really- just need a function to trigger the joypad or whatever input, in the NES software, and from there we can add quadaflank usb super sync 4000.
Neil: The easiest solution for testing would be to get a Arduino, port manipulation & microcontroller flashing is fast and simple using their framework / ide, which makes for a faster prototyping / testing environment. *ITS SUPER EASY*
Search will eventually search all content. I don't feel like coping other site's bad UI.
The user page needs to be redone. It's still "stock" ... It's on the list to do. Thanks.
Dead kennedys, both new and old, suck.
actually now I think about it, osx has a graphic eq and a parametric eq audio unit installed by default.
