Before, virtual instruments were possibles, but we need to setup a virtual midi cable, and a VST host ...

Now it is even simpler, as vArranger includes a VST HOST with ASIO/WASAPI low latency output. It also includes a powerful virtual instrument that can load SoundFonts samples.

Now, I tend to prefer to use the included synth with soundfonts for the accomp parts, because I am sure of his behaviour. It is full GM2 compliant. It reacts perfectly to program changes. Most of VST instruments are not 100% GM compatible.

I reserve the big VST instruments for my Right hand solo voices, that can be controlled from vArranger

This is something recent in vArranger, and I still discovering all what can be done, but ... WOW !

I don't want to go hardware anymore
