Could you tell me if there is a gig bag designed for the VoiceLive Touch series?
No, there is no dedicated bag for the VL Touch series available. However, any case that fits and which has layers of "pick and pull" custom mounting foam inserted will do the job. The exact dimensions of the unit can be found here. Please also have a look on the VoiceCouncil forum to see which kind of bags/ cases other VL Touch users are recommending.
