Duophonic Membrane
In this up-tempo ditty, I managed to sandwich in several sounds from an old Yamaha PortaSound PSS-130 keyboard. This compact little music maker has a unique sound, all generated by a square wave generator. Don’t forget, you can download all of these songs for free at TransistorSandwich.com.
Catch the Square Wave
This song grew out of a “getting-to-know-you” session with a new thrift store find, the Yamaha PSR-225. This music education-focused Portatone keyboard from 1998 has many sounds and styles which hold up surprisingly well after all this time.
