The mk4 builds on the previous mk3 and adds these new features:
- a dot matrix display, making menu navigation, parameter selection etc. a breeze.
- a front panel accessible MicroSD card slot.
- compatibility with the Macro Machines Storage Strip.
- an internal precision clock allowing new algorithms such as a tuner, and pitch and frequency references.
The new version is largely software-compatible with the mk3, and the intention is to continue releasing new features for both the mk3 and mk4 in parallel.
The disting mk4 is expected to be available early March 2017. Pricing TBD.
