You can now find a tutorial on getting this to work on your Pss-x80 model keyboard here: https://youtu.be/n9iErxYeRVM
Well I've had this idea in my head for a hell of a long time and never got round to having a go at it, make acid on a bit of gear that is in no way designed to do so with no external equipment, the Yamaha PSS-580.
The Yamaha PSS-580 as I've mentioned a few times already in my videos is a bit of a wolf in sheeps clothing. Designed as a home keyboard and looking very toy like this keyboard could be easily overlooked but the facade hides quite a powerful synthesizer.
I had to employ a few tricks using the sequencer and programmable voice banks to get this to work that i might share in a tutorial if anyone is interested and I can find time to do a video where I talk to camera.
