The Tiptop Audio Z-DSP Eurorack module will be programmable via a USB cable.
Here is a diagram of the programmer cable needed to hook up the Z-DSP to a computer. This is a USB to memory card connector and it will be sold separately from the module itself.
Tiptop plans to offer a free programming compiler for writing code and downloading it to the Z-DSP via this cable.
