Caustic Song file (optional):
Advice concerning the signal flow in the modular ( caustic file is for beta 3.1, but this is also valid for actual version without machine input)
How to test it: First play the pattern, and then move your Beatbox after the Modular in the rack view. Notice the "flange" effect, caused by signal flow. This was already noticed with the Vocoder too, Rej explained why. This is not a bug, and can even be used in a creative way, but just an advice: better put your machine before the modular if you need to mix the two channels, to avoid phase problems. And this is not related to beta3.1, as far as I know.
In the modular itself: first play the pattern. then go to modular and connect the first mixer to outpout instead of the fourth. You will notice the same "flange" effect, caused by a small delay between the dry Beatbox channel and the modular channel. If you try with second and third mixer connected to ouptput, the delay will be reduced, and with the fourth mixer, no phase problem at all. So, for perfect channel phase alignment, I suggest to put the final mixer at the bottom right in the modular panel. However, I imagine that other processing in the signal path will affect this behaviour ...
