After a year of searching and designing, the next generation SwinSID is finally alive!!!. It is much more powerful and now it is not only SID-replacement but has also new features that allows creating music with better quality than AMIGA.
The new SwinSID is equipped with 32bit ARM Cortex M3 CPU running at about 100MHz (overclocked) and 512KB SRAM for storing sample data.
In a few words Mega SwinSID takes best from SID chip and Amiga PAULA chip allowing to mix standard SID synth with other voices playing sampled instruments from internal RAM like Amiga do. There will be also DSP engine to add chorus or delay/reverb to final mix.
I'm starting work on the firmware and currently it is in very early stage (it doesn't produce sound at all for now).
