I've been having the same problem for a year now. The footswitches seem to go haywire only during the summer time when its hot and humid. When the weather is cooler its alright. I've read another post on here about the Timefactor and Modfactor having the same problem. Must've been a bad batch I guess. I've contacted Eventide support and they suggested I send it to service but I find it a bit ridiculous to have to pay for this when its not an issue that I've caused but faulty switches due to Eventide. I debated buying a new one to replace the broken one but I fear it might have the same problems a few years down the road when its out of warranty.
