DIY Roland 100m LFO

This LFO is intended to replicate the user interface and most of the behaviours of the Roland 100m LFO (as found in the M-140 and M150 modules).
However, the internal circuitry is totally different to the Roland – it’s PIC based, using code derived from the Electric Druid VCLFO9D (used with permission).
The module also has a "hidden" sample and hold waveform option.
