I may have found a bug with the ER301 ADSR used with the sine wave oscillator. I created a patch with a Mixer > inside the mixer is a Sine OSC > on the level insert an ADSR. I left my patch idle while it was receiving a gate to the ADSR for more than 20 minutes with the sustain parameter highlighted. When I returned to my case and tried to adjust the release time the unit immediately crashed and rebooted. To isolate the issue to a possible software bug I tried my ER301 module in three different cases alone and experienced the exact same issue with times ranging from 20 to 30 minutes of idle time while receiving a gate. I experienced the same issue on both the 3 and 4 firmware. Has anyone else experienced this issue?
