Hello people,

I was looking for an open-source/free VST Host for OSX. Doesn't need to be fancy, I just want to load simple free VSTs to test some MIDI patches I'm building in Pd without using "mtof" or something like that.

Any suggestion? Thanks!

You could use an IAC bus and route the midi from Pd to something like Plogue Bidule

I've got one called HostX. It was written several years ago using Max.

I bet there are many like this out there.

Hope this helps,
Mitch
