Flexinoodle and I recently finished our collab: the fnpSID. It’s a stereo mbSID v2 with added gm5 support for easy PC<->SID connection.
The pcb is basically comprised of a core module , a gm5 module and two sid modules and 5 banksticks.
It runs off a single 9V-12V AC/DC wallwart.
Since the gm5 gives us 5 IO ports, you can hook upto 4 other MIDI devices up to it.
It has the option of linking together multiple of the fnpSID PCBs to allow for either multiple stereo synths each as their own MIDI port, or linking the PCBs via CANbus.
Up to 2 of the PCBs can be fit into a single case , turning it into either a 2x stereo SID or a Quad SID setup
To keep it as simple as possible the pcb does not have headers for anything else than needed - producing SID sweetness.
In the beginning we were a bit worried about the SNR with the usb and single supply PSU, and I went a bit overboard with bypass caps. But the result speaks for itself: Wilba : f*ck man that snr is sick nILS:“puking baby”-sick or “phat maaaan!”-sick? Wilba: like pretty f*cking good Wilba: is like my mb6582 without the cs
Working on this little beast was a lot of fun and Flexi and I really like the results We would like to thank TK for this incredibly nice project, Wilba for being a third pair of eyes with major pcb OCD and building one of the 3 prototypes and everyone else who made this little toy possible!
I don’t have any fancy gear to measure it… nor any sound engineer learnin’… I just hooked it up raw to my Sony MDR-7506 and can hear the SID’s internal “noise” and not any noise from the PCB itself, if that makes any sense.
