Roland produced a number of SoundCanvas and related products. The SoundCanvas 55 came with an optional device called the SoundBrush 55. This was a floppy based MIDI recorder and player. Musicians could use it to either play back MIDI files or alternatively to record their performances. We will of course use the device to play back video game music without the need of a PC! I will have a look inside this device, which is well over 25 years old and also will hook it up to my SC55 and the MT32.
