Sewastopol is a multifarious module that lets users incorporate external gear into their eurorack modular rig.

This includes exporting line-level audio signals, importing audio signals, and generating control voltage signals from incoming audio.

Compared to the original, this version features a brand new preamplifier circuit, an enhanced ergonomic front panel interface, and much more.

Potential uses include orienting the module as an envelope follower, extracting signals from integrated external audio, input/output routing of external and internal signals, FX send/return duties, and comparator duties.
