I just made a DVD of most of my sample library in akai and giga format.
It contains samples all of the factory presets for:
SCI PRO BASSES,ARP CHROMA,MINI MOOG LEAD 1,PROPHET,ROLAND JUNO,YAMAHA SK20,ARP 2500
It also contains Roland TR kits, Alesis D4 and many other sounds I have tweaked over the years.
It has 527 files organized into groups (Analog Synths, Drums, etc...). There are way more than 527 sounds though. Each bank contains many programs. I would estimate there is close to 1500 sounds in this collection, as many of the files have more than 3 sounds.
If you would like a copy of this on DVD, please message me.
