I just needed some time to prepare setup reflecting your configuration, namely having installed SynthMaster, Syntorus and FT Studio 12.2 32bit on Windows 10 64bit, but unfortunately despite my efforts I couldn't reproduce the problem. So could you confirm me whether this problem happens when you create new (empty) project with SynthMaster and Syntorus present only? Also since you use integrated sound card, could you try out installing and switching to ASIO4ALL driver? It's probably the most efficient and most extensively tested non-native ASIO driver there is.
