Update

Thanks all for the replies.

I have since tried something I suppose I should have really tried before my original post 😳 … I have tried a different plugin.

I am still having the stuck note problem using Alchemy instead and therefore I have concluded that it was not a problem with Zebra.

I have also learnt about bouncing (as I said I am new to all this) and so therefore I have been bouncing my synth tracks once recorded. Once I render the track I don’t have the problem with stuck notes.

Therefore the problem has lessened but I must report is still a small issue on my system unfortunately.

I have all my plugins stored in c:vst plugins with Podium configured with this as an additional path.

I am using ASIO4ALL drivers and an MBox mini if that could have anything to do with it
