Roland SH-3a with Built in Case

via this auction

"A very bubbly filter that can get very elastic and a lot more solid sounding than an SH-101. The additive waveforms is a unique feature and sounds awesome with a bit of added echo for depth. The Sample and Hold feature is also very unique, with a lot of modulation ablities you can get almost sequencer like patterns from it. It’s also got 2 LFO’s, not many synths from this era have these design features!
If you’re after something a bit different that can still pull off deep bass and big leads this might be what you want."

TinySID on a 16 bit PIC

"Ater successfully getting the TinySID library running on a PIC32 [1] some time ago, I recently wondered, if the 16 bit MCUs from Microchip would also be fast enough to run the code. It turned out, that they are, at least the 40 MIPS models (PIC24H and dsPIC33F).

A big hurdle is the (compared to the PIC32MX) small RAM on these chips. Since the SID tune must be loaded into RAM, only some small tunes will fit into the 8 kB of the MCU used on the Web Platform [2] I had at hand.

However, the source code [3] and binary [4] are available from Google Code. The PWM output is on IO7, and IO8 is used to switch the tune when pulled to GND.

Have fun,
Markus
