Thanks for the help, there are many games & demo tunes that use sampled music & sounds, along with "standard" SID sounds. Some tunes are fully sampled, created on other music devices then digitized and pumped through the SID, i suppose totally defeating the object of creating music with the SID. But it's fascinating how this almost 25 year old chip handles these samples and adds its own definition to them. Thanks for the compliments on my box, i shall post some better pictures when i am back at home on monday. Heres a classic sample tune from Jeroen Tel, Outrun Europa from Sega 1991. Emulated by SidPlayer, sadly not my real SID :( Outrun Europa - Jeron Tel.mp3 Outrun Europa - Jeron Tel.mp3
