All sorts of companies have been giving away their apps for free or offering extensive free trials so that everyone stuck inside during the coronavirus pandemic can learn new skills or get inspired. Roland -- creators of iconic synthesizers and guitar effects -- is the latest to join in. The company's Zenbeats is a cross-platform digital audio workstation, allowing users to create songs on mobile, desktop, and even Chrome. The base tier has always been free, but the next step up, Zenbeats Unlock, typically costs $15 and includes more instruments, effects and presets. Roland is temporarily offering free downloads of this version to iOS and Android users.
