If you raise the INPUT L / R level on the MASTER page with the state that a somewhat complicated sequence is played (using more than 2 - 3 tracks and more than 5-6 voices), the probability of 2/1 Petit noise will be pronounced at the beginning of the measure (even if the sound source is not connected).
Does this symptom also occur with Digitone that you have?
I actually got this exact sound once while just running a few tracks on Digitone. I thought it was maybe a bad artifact I had created from experimenting but perhaps not. @Ess is on it though I’m sure it’ll get fixed.
I attempted to run Sysex Dump, but that item was not found in GLOBAL SETTINGS MENU.
Is it not displayed if something is not satisfied?
The current OS is 1.01.
