Jim, I have full version. I grabbed it some time ago on their flash sale.
But before that, I tried it as a demo. It did not require ilok. In DAW I am using 64bit VST, but for BIAB I installed 32Bit VST, which I can not get to work. VST simply does not start/load..

Since we talked about "chord builder" and inputting the chords into BIAB I thought I would continue with this thread as it is related...
Just does not feel right to consider spending $100 for bluecatmidi program. I do not need full power features of the wonderful Scaler in BIAB. I just want to use it as a reference for finding right chords for the job. I do not need complex routing to transfer the chords to bars... as Bob mentioned (if I understood correctly) chord structure is not a part of MIDI protocol. So I will write them manually to bars.

I think I know how workaround can be achieved... by using some sort of standalone VST host and use internal sounds of Scaler as reference, keeping both programs (BIAB and VST host+ Scaler) open. I was hoping it can be "plugged" directly into BIAB...

P.S. I think the Scaler surpasses "chord builder" in many (MANY!) ways, except of course, for entering chords directly to bars. Just an opinion.
