ACID 64 player is a Commodore 64 music player for Windows that can play SID tunes on sound cards with a real SID chip, like the HardSID card and the Catweasel MK3 PCI/Flipper card. It emulates the MOS 6510 micro processor to run the code of a SID tune and controls the SID chip (6581/8580) for playing Commodore 64 music.
I bought the Catweasel MK3 card 6 months ago, plugged in a spare 6581 I had lying around and then nothing.
Thanks to Wilfred Bos I now listen to a real 6581 SIDchip on my AMD 2GHz+ Windows XP system.
Quantum 64 is a harsh and aliased digital synth with single DCO and multimode filter. It is inspired by Commodore 64's SID soundchip but it definitely is no emulation. The two special ingredients that make the soul of Quantum 64 are the arpeggiator and the degrader/quantiser unit.
Goattracker (both mono and stereo versions) was updated for better hardrestart handling (wavetable also executed on hardrestart frame) and possibility for manual fadein/out of music. Of course, these features pay the price in increased rastertime but if you want it really low, you?re using some other programs anyway :) [Posted by Cadavar on c64.sk]
