This is so old but incase anyone still trying to find out if this is possible I'll go ahead and tell yall. This was my secret back in 2004-2010 when I was crushing out shut I had a secret that I only revealed to 2 people. Now I'm old and had to face reality so my production career is long gone and I'm here to say I own an emu sp1200 with 80 seconds of sampling time. I took an electrical engineering class in college and me and a gentleman known as care clusaki had 2 sp's and a slu of other samples in a studio we owned... it's really simple once you learn about circuits and computers, soldering. Signal flow...zzzz anyone ever put a memory expansion in a mpc? Look at how the plug wires into the board . Well on sp no extra spots on the board are available so what we did is tear out that low pass vs out pit **** and used those spots. Same for hi pass and the other useless one. From the back of those spots we re routed to the 7 additional memory stick plugs (hard to track down but it worked out) then left a bunch of slackcuz ur gonna have to pretty much mount them any where they'll fit them splice it all to the banks abcd wires (before where they split off to pass and faders) make sure all ur soldering is tight . Then we assign every memorychips to each bank (then chained together) if your still with me , put the face back on but don't screw it together for a test. The machine will still only say u have 10 seconds but each bank will say u have 10 seconds so 4 banks=80seconds and if u speed up ur samples going in it's more like 2 minutes! Make sure everything is functioning (except the 8outputs cuz that's now gone) and now your a mad man beat wizard with a set of balls that will make a bull blush! U also need to know back then we were paying maybe $500 for a sp1200 and didnt catr if we broke it... I dont think I would do it now that the damn things are 5gs and up but you might .. also it really wasn't necessary; just faster cuz I wasn't having to trim up **** to get that extra 2 seconds. Incase you wondering, yes I still have it,yes it still works and no not for sale! Been offered 10g and offered a motif, eps16 and mpc instead.. peace!
