dsPIC based VA Synthesizer

[mobith]

fantastic!! i'd also love more info on this!

[docfraktal]

It look and sound like a pro instrument, the sound is FANTASTIC..

But i have a question, what does it mean "dsPic" ??

Thanks for your answer !

[PsYSMmusic]

@docfraktal dsPIC are the ICs (microchips) that control the MIDI input and provide the oscillation (sound generation). I'm starting a synth project with the ds' as well.

@PsYSMmusic

Thank you so much !

I hope to see your project on youtube when it's ready to play !

Don't forget me and send me a message when it's done, i'm curious to see that !

Greetings from france !

Hi, your project is awesome! Well done! I plan to build my own synth using dsPICFJ128GP802 devices integrated with the Z80 computer project ive been working on heres my youtube page:- youtube.com/watch?v=aR2KK0M4AS­8

incredible!!!



[aren88888]

Amazing synth !

I am loving it :)

[Psychlist1972]

Did you ever end up releasing any details on how you built this? It's one of only a very few home-made synths here that does more than generate annoying pulses. The filter is super thick sounding as well.

Great project.... where can I find the schematics?

[Jimmy333x2]

dsPIC powa!!

[jimbobmcfred]

this is a really cool project! I've doing something like this myself as a learning exercise, I did DSP101 as an elective, but we only went as far as the maths: Z-transforms and the like, but never wrote any code! So I've just bought the microchip microstick. (found this with a google: "dspic synthesiser")

Wondering if you could point me in the right direction, you mentioned some papers, do you have any code you don't mind sharing? Also do you have a website/blog I could follow your progress?

great machine!

Amazing sound

[migou1]

Cool project ! I'm looking forward to play around with my dspic33f i have bought months ago!. I don't have much time for projects right now, but i'm very interrested in audio effects... since there is not much doc on dspics capabilities, it's very encouraging to see what they can do ! ... Do you use MIDI to control the notes? and do you have references i could look up about algorithms and filters you used in your project ? Tnx and good luck for more! ;)

[EATYone]

Sounding very good man, do you plan to transform this project in a DIY one for those like me wich are not good in electronic?

Please answer me yes!!!!

[Acidcoder]

Thanks!

With all this positive feedback I'll have to release a kit ;-) right? But I can't promise anything...

[Synthdude13]

@Acidcoder It would be a pleasure to build this, because the synth sounds very nice to me!

[MaxSynths]

@Acidcoder Really nice synth! Any additional informations?

[ak1m0t0]

pretty cool

[valdiorn]

what kind of DsPIC are you useing? How are you implementing the filters?? (can the DsPIC do decent FFT?) I'm very very interested in this project (I'm an electrical engineering student). Please put up a web page with more information, I want to know more :)

...and the sound quality is excellent!! :D

[Acidcoder]

For the moment I'm using a 33FJ64GP802 device (builtin 16bit audio-dac) @40Mhz. Filter is a digital moog model (four 1st order lp blocks in series) with a non-delay feedback loop + some cheap non-linearities. There are several papers discussing this problem on the web. Good exerice for an EE student (I'm one too ;-) (yes, the dsPIC can do FFT, but i don't use it here)

[valdiorn]

PICs never stop surprising me :)

[TexZK]

@Acidcoder Cool, I own such a dsPIC and I'd like to build a cheap FX module for DJing. I'd like to give a look to your source code and schemes.

Could you please contact me via private messages? I'm a n00b with 16-bit PICs... I just need to give a look to how you are manipulating data without an FPU.

PS: I won't be annoying ;-)

[tab8k]

Very cool sound! Where I can find more info about this?

[Acidcoder]

Maybe I'm gonna publish some more details soon... But what are you wondering about?

[network909]

cool machine man!
