Toy Keyboard Bass Station is a free sample pack containing a set of multi-sampled bass instrument patches in WAV format and a set of instrument mappings for NI Kontakt 5. All of the included sounds were created with the Yamaha PSS-390 toy keyboard and recorded through a compact tube preamp.
The Yamaha PSS-390 is an unusual toy keyboard which features a rather cool FM synthesis engine with some unlocked parameters, making it possible to completely modify the factory sounds. There are 99 factory patches in total and every patch can be edited using the rudimentary and at the same time totally awesome synthesis engine.
