My unit is fine, I checked for that. The official latency of the H90 is 4,5ms in series. Using inserts adds 3,8ms each. Which means using the H90 with two inserts will add up to 12,1ms. Not counting digital pedals you might put in the loop.
In comparison, the Quad Cortex running 8 blocks in series has about 3,5-4ms and a FX loop adds just 1,75ms. Tonex and Boss perform even better. So the H90 is definitely on the higher end when it comes to latency.
