I found the long version of "Shaker" again (and this is a much older instance of it.) I also found a long version of Claps1!!! So, I was checking out the samples on Unknown Stars' 1987 Aegis Sonix scores disk "Sonix Concert 1" (both because I'm interested in the samples people used at the time, and also, this disk has a lot of early S.L.L songs [from a year before his first tracker song got released; here is the link:
https://demozoo.org/productions/223307/]), and I clicked on "Shake.instr" and noticed that the
waveform looked familiar (yep, i can recognize
some of these sounds by waveform now), so I played the sound and, just as I suspected, it's "Shaker". But, it's the long version again, and this disk is from 1987, the year Karsten Obarski's Ultimate Soundtracker was released, meaning that either this Sonix scores disk ripped these sounds almost immediately after TUS (the ultimate soundtracker) was released, or....maybe Karsten got the Shaker sound from this disk (or another Sonix disk that happened to have this exact same shaker sound), which seems especially likely because some of the other ST-01 sounds are from the Fairlight, and a lot of Sonix disks (and even Sonix's built-in instrument library) has a few Fairlight sounds, and Karsten Obarski has never mentioned having a Fairlight. Anyways, I'm going to check out some of these other sounds. R_Astley_tomdrum (heh, it's the rickroll tomdrum!), Sussudio_smalldrum sounds cool, Tambclaps sounds...wait a second...this sounds eerily familiar....ohhh my gosh! it's another ST-01 sound! This is Claps1...but..longer? Yeah, I feel like this
kinda sort-of barely supports my theory that Karsten ripped some sounds from Sonix score disks. These are Yamaha RX- drum machine sounds, but I don't remember Karsten ever mentioning
anywhere that he had
any sort of Yamaha drum machine. So, these two samples most likely originated from this disk, or some other disk that also had these sounds. I have them attached here.
