Tried it and no change. Thanks for info though. FYI - this is a new, fresh install of BIAB win 2020. Just double clicked the install files "bandinabox_realband_2020_pro and then hiq_instruments_sforzando and accepted all the default locations for files. Haven't changed any options. When I choose an RT style I get all kinds of messages in the yellow boxes ... style not found, instrument(s) not found etc. And basically the style doesn't play. This may be part of the whole problem?
