Just thought I'd point out that all those sample collections on www.hollowsun.com arrive with a .akp file which is an akai mapping format. I've just successfully tried a bunch of sample collections and it works a treatEaster egg #2 - hidden file formats
There are built-in file format importers in Tachyon which are not exposed by the ONE/solo GUI. However, they're still there. By setting the drop-down file type to "*.* All Files) you can load Akai S1000/S2000/S3000/S5000/S6000 keymaps (not synth settings and with some limitations). You can also use ONE/solo to load our own DS404 format (full import, all samples and parameters!).
No need to faff about converting them to soundfonts and the amplitude and filter envelopes, lfos etc. can all be used to tailor the sound.
Nice feature, Dave
