Yes but I've started experimenting with integrating other bits of gear, although everything gets written "in medium" on those as well with the exception of some sound modules.

vgx is probably on the money in regards to the aliasing going on. The characteristics of the spectrum graphs I have produced look strikingly similar to some of the ones I have seen when looking at discussions over downsampling (which causes aliasing).

I still very much doubt it, and I brought out my Game Boy to try it just now. I can tell you right off the bat that my listening conditions aren't the best, but I can't hear _any_ folding or post-nyquist frequency mumbo-jumbo. The harmonics of the square wave, although harsh, are very clear and seem undistorted. The oscillator also sweeps up well into the ultrasound range without any of the folding noise I'd typically identify as an effect of aliasing.

What I can hear, though, is some constant high pitched bus whine, and also some lower frequency zipping noise when using an envelope. The latter noise has some high frequency content, too, which is very obvious and quite annoying. Maybe this is what you are hearing?

Yeah the square waves are closer to analogue oscillators so there shouldn't be any noise related to aliasing there, on closer reading I noticed m00dawg was discussing that, I was talking about the wave (psg wavetable) channel. Sorry to anyone if I was a bit misleading. I am to a certain degree making assumptions, I can hear aliasing or something similar to it on the wave channel on certain settings, I don't notice the same effect on the other channels.

Well basically it's a digital synthesizer, and one of digital's unfortunate characteristics is when it reaches a certain frequency, that is, the Nyquist frequency, the system can generate weird tones related to the original, otherwise known as aliasing. This particular frequency varies depending on the device, as an example you might have a sound card that says it has a sample rate of 44khz or something, half that (22khz) is the Nyquist. The only ways to overcome this are using extremely steep filters which is extremely expensive in the analogue domain, or raising the sample rate which is somewhat cheaper. For a mass produced 80s gaming device, neither option is particularly feasible, but it was also never intended to be used as a hi-fi playback device or a professional synthesiser. Additionally there's cheap components throughout the entire unit which aren't isolated from the audio components, so you get weird noises from the cpu, screen, even just electrical currents running through the unit, which all affect the sound in different ways.

Curious, is the power save option turned on in LSDJ? That can cause extra weird noises sometimes.

Anyway some of these things can be overcome via the pro sound mod but without redesigning the synthesiser and audio circuitry you can't get rid of all of it.

Your front page crashes my browser if I try to play anything, I'm not sure if it's having way too many applets on one page or something to do with preloading so much data at once but it means I can't listen to any of the music on there. I don't have the same problem if I click on the links to the music pages. Is it absolutely necessary to have so many applets pulling data simultaneously on the front page? I like the idea of having recent tracks listed on the front page as well as having a way to play them without doing too much clicking around but I don't have the patience or bandwidth to wait for 40 tracks to load. Surely there's a much more elegant and less resource intensive solution you could consider instead?

Dmgs have a bit of aliasing which may be what you're hearing, they also generate a certain amount of strange noises and artifacts simply because they use a cheap synthesizer/op amp. It's particularly noticeable on later models (pocket is one of the worst offenders imo) but there's not a lot that can be done in most cases, it's just a characteristic of the sound generator. Curious to see if pro sounding improves it at all.

I worked with a guy who did a lot of radio work, whenever he needed music for similar sorts of things he'd use something from a music library. These are usually dvds full of original music specifically for use in advertisements, stingers, etc, although there's probably websites dedicated to that sort of thing as well. You can get them for free but bear in mind they are definitely not royalty free, it is expected if you use their music you'll pay royalties to them ... that said, not many people actually seem to pay any royalties, according to him. If your company is trying to be legit though the people who put them together are easy enough to contact so working out royalties etc won't be too hard.

I don't think mine has been misspelled anywhere but occasionally people call me VGA

The kpq is a pure fx processor with the advantage of being able to run 4 effects at once. The kp3 only runs one at a time but is also a sampler, MIDI controller, MIDI clock source that can detect tempo from an analogue source (debatable as to whether its tempo detection is much good), extremely basic synthesizer ... Which one is "better" depends on what you want to use it for, maybe try looking at YouTube videos of them in action or try them out in a shop or something?

The headphone output is usually ok but the pro sound outputs are way too loud, distorts like crazy, which is a shame.

... turn down your volume of your gameboy...

I realise this is a solution, my gripe with the unit in general is that any low impedance signal at a high enough (read: reasonable) volume causes distortion. It's designed specifically for high impedance outputs from things like headphone amplifiers like you'd find on an ipod or something. This is a problem with my setup specifically because I pro sounded my game boys to lower the noise floor and make them loud enough that I wouldn't need to ramp up the gain too much on my mixer. Lowering the volume or using the headphone output negates both these benefits.

That all said it's not too bad through a PA system, just a nuisance if I'm recording it. They're still fun to play with anyway.

Once upon a time it was pretty much essential to have one but everyone with half a brain has migrated to Facebook, almost everybody uses Facebook these days so it makes more sense to set up a base of operations there imo. There aren't as many options for interactivity but at least it means random hard dance djs can't spam everyone's wall and inbox with adverts for their new merch and music etc, just everybody's news feed smile

Yeaahh boyyyy!!!

theyve made ones for guitar cables, and i have a converter for guitar cables. a few weeks ago a friend of mine was jamming in our schools hallways with his guitar and his ipod, and there was zero latency. i imagine with I/O capabilities they could make a similar app for synths/FX.

That's the IK Multimedia one right? The problem with it isn't so much the latency but the frequency response, it uses the microphone input which is meant to be used with the iPhone headset, the spectrum ends up being far from flat and rolls off a lot of bass and a bit of treble. This is ok for its intended purpose (hands free kit) and is acceptable for guitar, but you run into problems when you use it as a general purpose fx processor, it's not exactly ideal. That and the input is mono - if you wanted stereo processing you're SOL.

Interestingly enough it looks like if you have any of the new generation iPhones/iPod Touches or an iPad there's no line input on the dock connector anyway sad there's hope if you have an iPad, once some audio interfaces become supported on the camera connection kit, but until then ...

I heard a rumor someone's working on a kaoss pad style fx thing for iOS but I don't know much about it besides that.

TouchOsc is really cool as well, it's an awesome controller. It does require a computer however.

The problem with all the fx things available is there's no interfaces available for the i-devices with both line input and line output, at least not commercially. It basically means there's no hi fidelity way of getting sound in and out of the things. You can buy one of these  http://www.chargeconverter.com/shop/connector.htm and build your own of course but that's the only realistic option available.
