Thanks for taking the time to contribute to these threads by the way Guillaume, it's very much appreciated. :-)
Always nice to hear from the CEO/President of a company on the boards!
Thanks for the warm welcome, I appreciate it as well.
Quick question: if you ran two separate vb-101 units with seperate heads at the same time (I have a sweet framtone switcher) and had very different miking scenarios (one close miked with a 57 and one a few inches back with a royer), would you need to think about phase issues, or would this issue not materialize (ie. the recorded signal would happen at exactly the same time in phase).
OK, I have done this test,
Same amp, two tracks in Reaper of the VB-101's loadbox direct output.
I send them to 2 iterations of the PI-101 plugin (same process as in the VB-101, apart from the load compensation function).
At the beginning, both microphones are full axis, close miking (ie position 0,0 in the software). The cabinet is a 4x12 embedding Greenback speakers.
From 0'0" to 0'14": only SM57
From 0'14" to 0'26" : SM57 + M160N, no pan, same level
From 0'26" to 0'42" : the M160N is moving from position 0,0 to position 0,100 (10 feet away)
What you hear is coming from the different frequency responses of the two different microphones. For example, if one has a huge hole around 2KHz at a certain position in the room, the signal will be lowered by this value. As a matter of fact, some phase effect comes from the room and the number of speaker the cab embed. In this test the time alignment is made in Reaper and the phase alignment is part of the Torpedo Technology.
And the action of moving the microphone can be clearly heard if you try our free Torpedo PI-FREE Plugin, especially with a 4x12.

I don't know if a similar test has been done with some IRs coming from 3rd party suppliers, should be interesting but not that easy to move the microphone linearly...
