Scale lock still causing hung note on external synth

Hi I am still experiencing this problem in the latest version 1.5

An external hardware synth? There’s a panic button in Scaler ( ! ) this will clear any midi jams which is very common when sending note out to external midi synths. Is this what you’re referring to?

thanks but the issue is it hangs everytime I play a note. The problem occurs with multi part synths playing through the scaler. When I use a single channel part its ok
