A very serious bug in the Beta is the Env 1 mod problem. 1 of the 5 voices doesnt react to modulation. This goes for the TEO-5 as well. i got this answer 25/8:
The Take 5/TEO-5 Env1 mod source issue is on our bug list, and will hopefully be tackled in the next OS overhaul. I can not say for sure when this will take place, as the software team is currebntly busy working on new projects. They will circle back around to existing instruemnts when their slate is cleared.
