indeed its technically not sidechaining, but effect wise yes, and it easyer to controll the effect, but its still winds down to preference.
i find using the compressor time consuming but thats just me, but other then that i use ableton's compressor for sidechaining, i find it more easy when routing and less confusing then fl's
in my opinion tho.
If you want to get into electro might i recommend the Roland jp 8080 (RACK)
