Just another chiptune based on Linus' Akesson's tracker/player, but one I made myself. I also fixed the port settings for the lights, allowing the LEDs to shine brighter. Check out my blog for the source code for this specific tune:

  • @therobomaker957 Ah, you just open a terminal, change into the tracker dir, then run "make". Now you should have an executable called "tracker" in that dir. If you don't, you're missing the build environment or libsdl - just install that using the package manager.

  • @thelaaz I just need help opening it. I am running OpenSuse 11.3 but have Ubuntu and will try it. I hope it works.

  • @therobomaker957 It's here: bearborne.blogspot.com/2012/02­/lft-tracker-howto.html I really didn't know where to start, but seeing your videos, I think I may have given you the right hints to start with. Send me an email or pm if you need some more details.

  • @thelaaz Have you made the tracker blog yet? I really want to start composing. Thanks.

  • @therobomaker957 Hi there! Well, that's a pity... for me, the code ran out of the box! The original code only played the tune once. I added a crude looping by just running the initializer again. Obviously, that isn't enough ;) Whether it works or not may depend on the contents of your program ROM... The looping occurs in line 284 in my code, where it says "if (songpos >= SONGLEN)". You gotta change that somehow. And I'll write a blog post on how to use the tracker this week, OK?

  • @thelaaz I ended up being able to do it by modifying the code on the chiptunes to do the same thing by painstakingly checking each line. I noticed at the end of the glitchy part, it just emits a high-pitched squeeling noise...why? Also, can you remove the glitchy part at the end? I plan to add some other beatmakers using other devices (Picaxe) and what some non-glitchy music. Also can you make it clearer on how to make your own tune? Thanks a million.

  • @therobomaker957 Perhaps because the output was too quiet? I used a transistor to amplify it. Did you connect the speaker to pin 3 and GND? Did you make your own tune with the tracker or did you use my sketch directly?

  • There was no audio when I did it. The LEDs flickered as said in the blogspot article but there was no out put on pin 3. Why?

  • @keoni29 The channels are mixed digitally @16 kHz, 8 Bit. One PWM output is used as DAC. A cheap way to do it, but it works ;) Grab the source from my blog if you like (check out the link in the video description - posting a link here doesn't work somehow...)

  • Do you mix the channels digitally or with those resistors?
