Synth night is a cool place to hang out with fellow gear nerds and try stuff out, kinda like an internet forum come to life. Sometimes there are explicit performances/demos but mostly it’s an open jam format.
There’s definitely a lot of electronic music going on around town, even if it’s not explicitly synth-based. All the Musica Practica events I’ve been to that @YEVGENIY has posted throughout the thread are always super solid, definitely follow them on facebook/sign up for their email list. Chuck Van Zyl has the ambient/Kosmische contingent locked down as @Struggle has mentioned. I just played the last Gatherings concert of the season this past weekend and it was great to hear these types of soundscapes in such a reverberant and beautiful place (St. Mary’s church). Forgot to post about it here, I’m bad with promotion 
Bowerbird is another organization to follow; they generally put on concerts focused around 20th century avant-garde compositions, but not exclusively. Some of these are electronic and some are not. & there’s a whole noise/deconstructed dance music thing happening in warehouse / diy spaces all over the city which I have only brushed up against here and there… LXV, Ulla Straus + Pontiac Streator are the artists I know to follow to learn more about these spaces.
