]]>PS, I'm not dead. Hopefully I should be up to speed by the end of the week. Half the battle is writing informative posts, and I kind of got stuck on that with the "filter" ROM that I dropped early. (See the last post on the previous thread page.) And please check out that ROM and give some comments.
]]>fatconv("filenamehere")In this case it's assumed that you have prepared a raw sound file called filenamehere.raw but notice that you shouldn't include .raw in the code. If you're getting If you're getting dawg'd, it's probably because the raw file isn't the exact right length.
]]>Ok, brief explanation on how to do it, but then you're on your own. Create a file that is a 1 bar loop. Convert it to 8 bit unsigned mono and 32768 samples long. Hint on the last part, making it exactly 1 second long and then converting it to 32678 Hz sample rate should at least get you close. You might need to manually trim or add a couple of samples with a hex editor. If you're adding samples, repeat the last sample value in the file or so. (Who ever said this was supposed to easy?)
Run the following Python script. It will convert the file you've created to the 4-bit format the Gameboy so much craves and create a new ROM with your sample.def fourbit(x): return ord(x) & 0xf0 def fatconv(fn): f = open(fn + ".raw", "rb") x = f.read() f.close() if len(x) != 32768: print "File should be 32768 samples long, yo. 8-bit unsigned mono is where it's at, dawg. Raw with no header. (That's what bshe said.)" return g = open("amenizer.gb", "rb") gb = g.read(16384) g.close() y=map(fourbit,x) y=zip(y[0::2],y[1::2]) #f = open(fn + "-conv.bin", "wb") g = open(fn + "-rom.gb", "wb") g.write(gb) for i in y: #f.write(chr(i[0] | i[1]>>4)) g.write(chr(i[0] | i[1]>>4)) f.close() fatconv("filenamehere")However, the final version of this application, when it comes out, will surely blow your minds. Just a prediction.
First off, thanks for taking the time to post this. Now, let's assume I have a basic knowledge of snakes, and even less for coding. Did a bit of reading last night, and pretty sure I can figure out how to cast this spell. Only questions I have, quite probably dumb ones, in the incantation above, the part that mentions 'dawg's' and stuff; should I leave that as is, or am I supposed to add my own 'something' to this line, eye of newt, tongue of frog, etc? Also, at the bottom 'filenamehere'; is this where I would put the name I want the file to have when it is created, or the name of my audio sample?
Are there any other fields above that I need to change or anything? Last but not least, do I put this in a folder with my sample and just start chanting the above passage and a rom appears?
Looking forward to further investigating the black arts of rom creation and the arcane knowledge held within.
]]>What it is: A rough and ready MIDI synth with a filter. Use it with an Arduinoboy or NL MIDI adapter in raw MIDI mode. It has no UI except dirt lines to show that the CPU busy. Please excuse the bug (or rather, lacking implentation so far) where all sound is cut whenever any key is released. Could be annoying if played with a keyboard, but sending it notes from a sequencer should work ok. It accepts a cutoff on CC 71 (hex 47 if that's your thing.) The actual filtering currently pre-rendered and same as an LP fade on a sawtooth from 10-FF in, with a Q of 2, in LSDj. The novelty however is how the sound is loaded into the wave buffer, which sounds really smooth. Hint try connecting a modulation source (LFO, envelope) to send to the CC, if your client allows it. At a high frequency if you want. It's not finished yet, but just imagine the possibilities in the meantime.
good work anyhow

Hahaha that actually sounds awesome. I wish I could make sounds that cool on purpose!

I know you are busy, but any word on this? I will love you long time!
