The MagicSound board from Patisonic is a 4-channel DMA sound expansion for the [[Aleste 520EX]] from the same company.
The '''Aleste 520EX''' is a rare CPC [[Clones|clone]] with 512Kbyte RAM, its [[Connector:Expansion port|expansion port ]] includes some additional pins allowing external hardware to access the 512K RAM via DMA. The '''MagicSound''' board is probably even rarer, it's using the additional DMA pins on the expansion port, so it works only on the Aleste, not on normal CPCs.
