Re: MIDI Sync with MTV Music Generator/Music 2000

Did Nex ever end up getting in touch with you about working together? I don't mean to be pushy or anything, this project just really excites me. I guess since this mod would require a custom disk image, I would think that porting the functionality over to MTV Music Generator wouldn't be that importa...

Re: MIDI Sync with MTV Music Generator/Music 2000

Those are all great theories, but I was actually able to get in touch with Nex (the video's creator) and apparently the workaround is a little more complicated than we thought. He said: that project was in my early years before i knew anything about electronics. it was a super lame hack in which i u...

MIDI Sync with MTV Music Generator/Music 2000

MTV Music Generator (known as Music 2000 internationally) is what got me started making music back when I was young. It's a pretty basic tracker composition software that's very easy to learn, and it comes with an extensive library of pre-packaged sounds to work with. I find a lot of the default me...

Re: How does the CD player visualizer receive audio input?

OK SO My electrical engineering friend suggested another, much simpler method of accomplishing the analog to digital conversion. I already own and perform with a mixer that supports USB audio out for use in home recording. It has several analog inputs and multiple ways to control the input volume, s...

Re: How does the CD player visualizer receive audio input?

Alright, so I've received the ADC chip finally. It's very small (see attachment). I think I'll need a custom PCB if I actually want to solder anything to it with the tools I have. I guess my next step will be designing that PCB. I have pored through the data sheet of the ADC and wanted to confirm a ...

Re: How does the CD player visualizer receive audio input?

The data that appears in the buffer at the start of the SPU RAM has already been downsampled to 44.1kHz before it's stored. It's possible that just feeding in 44.1kHz data directly into the SPU CD input would work, but I haven't attempted that. Looking at that evaluation board, the extra parts appe...

Re: How does the CD player visualizer receive audio input?

The bad news is that the signal format on this link is a little unusual - most notably, LRCLK is 132.3kHz which, since the source is a CD drive with a sampling rate of 44.1kHz suggests that that it's being 3:1 oversampled somewhere in the CD processing chip. BCLK is 8.4672MHz, which looks pretty st...

Re: How does the CD player visualizer receive audio input?

Thanks for the quick response! My only experience with console modding has been older stuff like the C64 and the Atari 7800 so this is all quite new to me. What a goof on my part to think it would be an analog signal! As a result, you would need to use an ADC with a serial PCM / I2S output and conne...

How does the CD player visualizer receive audio input?

Hi all, first time poster here. I've got an old SCHP-700 PS1 in my garage that I haven't used since 2005. One of the things I remember most fondly about the PS1 as a teen was using it to play CDs and watching the cool audio visualizations in that classic PS1 style. [youtube]http://www.youtube.com/wa...
