here are the demos i did recently on my OB-XA. i do need to calibrate filter, its open a bit too much from the default setting. it may be of interest that i had all capacitors replaced for new ones on this obxa, so it has somewhat restored transients, brightness, and also noise floor dropped a bit:
I'll be adding to this page in order to provide some less "ordinary" demos of a few synthesizers.
Up now are some MS2000BR demos. All are single patches recorded in real time without external effects.
To be added later are JP8000, Fender Rhodes Chroma Polaris, MicroKorg, Korg Electribe EA-1, various Korg Legacy synths, and later on the x0xb0x (when I build it).
These are all fairly common, popular machines (with the exception of the chroma polaris) that people often ask about. Hopefully this resource will provide useful.
