SenPi Posted March 30, 2009 Share Posted March 30, 2009 So I posted in another thread a while ago that I was making some form of synth with an FPGA for school. Well it was due on sunday, and I have posted a video of what I ended up getting accomplished. All in all.. it was a pretty fun project. I just wish I had more time cause I know I could have made it way better. Either way, enjoy Quote Link to comment Share on other sites More sharing options...
Yoozer Posted March 30, 2009 Share Posted March 30, 2009 This is really cool . Are you using wavetables for this or...? Quote Link to comment Share on other sites More sharing options...
Hy Bound Posted March 30, 2009 Share Posted March 30, 2009 Thats pretty sweet, man. I've been looking into doing something like that recently. I may actually do it now . Hopefully we can hear some remixes utilizing that Quote Link to comment Share on other sites More sharing options...
analoq Posted March 30, 2009 Share Posted March 30, 2009 C 0 0 L indeed, haha. polyphony was a bitch for me, too. Quote Link to comment Share on other sites More sharing options...
SenPi Posted March 30, 2009 Author Share Posted March 30, 2009 This is really cool . Are you using wavetables for this or...? Yeah I made some wavetables from sratch cause I couldnt find any online lol. Thats pretty sweet, man. I've been looking into doing something like that recently. I may actually do it now . Hopefully we can hear some remixes utilizing that Haha maybe... the FPGA is lent to us from the school... so I'll probably have to give it back really soon... maybe I'll buy my own some day. C 0 0 L indeed, haha.polyphony was a bitch for me, too. Well.. I figured out a decent way to get more than 1 key working at once, but the big problem was my wave combining algorithm. Since I wasnt allowed to use signed values (i.e -xxx to + xxx) my 16 bit waveform tables were weird and I guess I couldnt properly figure out the math to combine them. (Also it didnt help that reading in midi data was a bitch.. I must have screwed something up cause I was missing some data every once and again. Like when the keys "stick" its because I didnt receive a NoteOff signal for that key. It was weird) Lets say were looking at a wave table graph | | | | -------------------------------------------------------------------- | | | | Well, middle was 0 (as usual), middle +1 = 1, Top = 32767, Middle - 1 = 65535, Bottom = 32768 so yeah.. it was kinda funky. But doing this makes me want to make some sort of VST or standalone vst type thing. Quote Link to comment Share on other sites More sharing options...

Dhsu Posted March 30, 2009 Share Posted March 30, 2009 Wish our digital design class let us do cool stuff like this. :[ Quote Link to comment Share on other sites More sharing options...
JH Sounds Posted March 30, 2009 Share Posted March 30, 2009 Lets say were looking at a wave table graph| | | | -------------------------------------------------------------------- | | | | I saw something else. Quote Link to comment Share on other sites More sharing options...
SenPi Posted April 16, 2009 Author Share Posted April 16, 2009 Update: So I ended up buying my own FPGA so I could continue this project yay! Also, I got an A in the course Quote Link to comment Share on other sites More sharing options...
