Bug latency appears randomly

Hello

I have problems with digitone

there is latency when I play with the keyboard, there is about 1 second delay, and when I turn it back all the keys do not light.

I turn it off and then restart it several times, the bug appears randomly

I have two digitones and get latency sending midi notes out from them but never when triggering tracks with internal trigs

I have latency when I play directly on the keyboard, but I’m not latency with the midi sequencer
