I have vocal and acoustic guitar tracks using the same reverb FX via Send. When the guitar tracks are Solo'd the reverb FX bus is also Solo'd and consequently the vocal can also be heard through the effect. The reverb send on the vocal track is not automatically muted and Mute button on the reverb FX channel doesn't work. The only ways I've found to get the bleeding vocal out of the Solo'd guitar is to pull down the reverb fader or disable the reverb send in the vocal tracks. This doesn't seem right to me. IMO, the FX channel Mute button should work at all times and possibly the channel or bus Solo should mute all sends from the muted tracks so the Solo output is not tainted by unexpected sources. Am I missing something obvious or is this a bug/design flaw?
