Thanks a ton for all of the help. I've actually been messing around with SDL for a bezier curve drawing app, so that works out perfectly. I was just worried about efficiency, but seeing as how Milkytracker runs quite reliably on my 3G iMac, I guess there isn't much to worry about.

Maybe I'll even figure out Cairo and make my own vector-graphics based tracker GUI API or something. I've always wanted to work on a modular MIDI tracker for use with PureData, and I suppose this would be the perfect opportunity.

I've been learning how to use GTK+, but it's very discouraging. It doesn't seem like any of the widgets are all that useful for building a tracker UI.

However, building my own UI sounds like an imposing-yet-fun project. It would be interesting, and to be honest, it's what I'd rather be doing. However, there are a few things that I'm not so clear on. For instance, if you're doing everything by rendering a bitmap, that would mean that all of the video processing is being done by the CPU, yes?

Also, what would be the most effective way to render that to the screen afterwards? How do you keep track of mouse clicks and what would be the best way to keep this project platform-independent?

I presume I would end up writing my own font renderer as well...

Sorry for pummeling you with questions, but I'm at a bit of a loss. I spend most of my time programming micro controllers and the DS, so I'm very lost when it comes time to deal with an operating system, much less a bunch of them.

With regards to the audio input on the ds, wouldn't be possible to get a ds headset and just chop the cable off and solder on some rca connectors? I personally have an attic full of broken electronics to raid for parts when I need them.

You could do that, but aren't those headsets a bit pricey to go around hacking them up?

Also, I'm quite certain that feedback delay would be fairly easy, and I'm sure you could get some filters going if you were so inclined. Everything would be fairly simple if I could only get streaming audio working in the first place.

It took me quite a while to figure out that the tilde key was add and shift-tilde was (un?)add.

I love it, though. I only wish that Milkytracker had a multiply current add-value by 2 (and/or 3) hotkey. Saves lots of time when you need quarter/half/whole/triplets fast.

Thanks for all the info. What was PPUI built on, though? I imagine it must be based on some sort of primitive window/drawing API.

I'll check out some of those, though. I'll probably choose whatever one offers the most in the way of simple hotkey-mappng and a nice looking (and customizable) UI, since everything else ought to be fairly negotiable.

I'm going to be building my own tracker for generating CSound scores, and so I need a simple-yet-effective way to build a GUI. Milkytracker is probably one of the most aesthetically pleasing trackers I've had the pleasure of using, and so I thought it would be a good idea to ask here first.

I've considered doing this, but the problem is that it's too much of a pain to rig up an input jack, and the normal microphone is too noisy for any sort of meaningful audio processing. (Other than, I suppose, noise removal. Unfortunately, it would be rather processor intensive to perform noise removal + other effects all in realtime.)

If you find any retailers that sell this sort of thing, or even somewhere to order the DS male mic connector, feel free to let me know. I wouldn't mind spending a little time trying to throw together a tutorial/some software so people can use their DS's as pocket amplifiers.

I do plan on eventually writing some software for non-realtime effects processing on the DS, but it's going to be awhile till I get anything significant done. It's a shame that I can't put life on hold, because there are far too many things I want to do, and not nearly enough time to do them.

Bear in mind, though, that they're likely to be a tad processor-hungry for low-powerered devices like the DS.

Yeah, I know. Luckily, this isn't going to need realtime processing, being an audio editor and all, although I've actually seen real-time spectral analysis done on the DS, so I guess that sort of thing is possible.

I'm using standard C and the Nintendo DS. The idea is to get a decent audio editor/sample-based synthesis toolkit going so that the people using Nitrotracker and other sample-based DS music apps will have something nice to prepare their sample material, without having to run to a computer to do it.

I need a bunch of filters. I'm working on a sample-based synthesis toolkit, so I'll need every bit of DSP code I can get my hands on. Right now though, I'm just trying to get some functional HP/LP/BP filters set up. Maybe a nice graphical EQ.

Also, what is all of this about Reason? There are a number of DAWs and VSTs that offer great sounding filters, but I'm confused as to how this is relevant to my question. I'm not trying to do anything terribly fancy ATM, I just need some basic filters for sound sculpting.

Thanks for the recommendation though. I'm a bit strapped for cash right now, but maybe I'll look into it later.
