Nah, it's written in internal SE SDK(like written into SE itself - a different format), not SDK3, only newer module examples are written in SDK3, hence why there is only examples of some of the stock modules, would be a ton of work to write the code in internal SDK and SDK3, in other words -> a complete waste of time. Ya can always write your own, that is what the SDK is there for. FYI, the SE Osc is an extremely optimized mip-mapped wavetable, not for the faint hearted.
P.S. Just simply switching something off isn't as easy as it seems, especially if you don't understand the code/SDK. It has to switch off at the right buffer position (timestamped) otherwise it will trash the buffer. Audio signals work with buffers.
