SwinSID - a pin compatible alternative to the SID chip

SwinSID is still in development and the new version SwinSID X2 is almost ready now. It is designed to emulate  two SID chip working with one MB core.  In fact SwinSID X2 has two AVR connected with single DAC

Latest firmware provides better sound quality (low aliasing), new waveforms and nice features: simple FM synth, two oscillators per voice and white noise generator.

Firmware is quite stable now with all features working, but I need to design layout for new MB module. If you want to help with testing or designing layout then let me know.

I will consider releasing the source code.

So, a SwinSIDx2 module? Sweet  ;D

So, do you have a circuit diagram and need a layout, or do you need both?

Hi everyone if you like you can download and listen some one on one demos left the 6581 R4AR right the SwinSID with actual Firmware  ;D

Have fun while listening... and always Remeber the SwinSID can do much more than only SID Sounds!

Here is the SwinSID playing alone with Digis ...

@TK

ofcource can you... no problem

and as I saw Swinkels updated some part of his site with some new Demos  ;D

If anyone has a favorite Sidtune which he wants to listen played by the SwinSID please tell...

Finally, my download page was updated with latest SwinSID firmware for MIDIBox and dual AVR schematics. There is source code too. 

I'm working now on the new SwinSID 1024 card with 512KB RAM and 512KB ROM for storing drum samples and new cool sampled sounds.

Maybe some day it will work with midibox as a external sampler (when TK modify control firmware) but first, it is intended as a hardware MOD player for C64.

Hi Swinkels,

Congratulations and thanks for your work :)

Will you upload the new source code, too? On your page I only found the source for the old SwinSid SE. And do you consider using English for the source comments of the new version? My Polish is a bit rusty ;)

BTW, maybe I posted to the wrong thread last week, so may I draw your attention to this post: http://www.midibox.org/forum/index.php/topic,11258.msg89914.html#msg89914

Thanks for the PCB. I haven't mentioned on my site that this schematic is for C64 version. It uses 74HCT138 for address decoding of each AVR from C64 bus. With MB we can remove this chip and connect CS signal directly to the MB core module as with MBSid - master CS goes to MBHP_SID:J2:SO and the second one to MBHP_CORE:J14.
