VirtualMIDISynth 2.x is the second generation of VirtualMIDISynth. 2.x introduces a deep and important architectural change: Driver and Synth components have been split in two distinct parts, while the Configurator is now included into the new Synth.

The driver is still a DLL, loaded by the MIDI application as 1.x, but now it only contains the "windows multimedia driver" parts needed to identify the virtual MIDI device ("CoolSoft VirtualMIDISynth") to the system and receive MIDI streams from MIDI applications outputs.

The received MIDI stream is then forwarded to the new Synth component: a new, isolated and independent process that listens to VMS2 driver instances and plays the received MIDI streams. Syncronization between multiple driver instances could be done easily, from a single point.

Required BASS libraries are now loaded by the Synth process; so a MIDI application can use BASSMIDI Driver using BASS v.2.2 and VMS using BASS v.2.4 with no issues.

VirtualMIDISynth 2 is currently at alpha/beta stage, and therefore is not by any means complete nor a stable release.

It is encouraged that we test the software out and leave feedback, reporting any additional bugs found to aid development.
