I do all my Mic Cues on M7CL and/or 01v96 via Qlab2 Midi CC as well..
i bought an x32 and missed this function so i ended up using an 01v sidecar for vocals and the x32 for the vox submix and band/effects.
the new v2.0 firmware should fix this.. i will install as soon as at least x32-edit works with the new firmware.. the ipad app is apparently months away from working with firmware v2 .. x32 edit for mac/pc/linux is supposed to be upgraded in about a week or 2..
i can tell you that with qlab v3 .. the OSC commands are very straight forward to control most command like volume fader or panning.. it also lets you control all parameters practically. one great thing is that with out any special settings on the x32 board you can not only access volume/pan on all 32 input channels but also DCAs /subs/etc..
i figured it out in about 10 mins.. and all you need is the OSC chart to know what command to send via the OSC cue in qlab.
i ended up not using qlab3 for that show as it was still a bit buggy at v3.01. but the next show i do with qlab3 whatever current version is like 3.16, i will be using OSC commands mostly because it can automate practically every parameter.
for shows at a theatre with qlab 2 i will use the new MIDI implementation in the x32. either way.. the digital stage boxes.. all the features etc.. the x32 is definitely worth it.. perhaps the m32 is too.. looks great. more expensive practically identical feature set and software.. but the preamps and hardware faders may justify the price bump.
i'll let you know how it goes in a few weeks.
