There are currently no mono reverbs on the Helix. Maybe this has been answered before but I am not sure I understand why this is the case. I would think reverbs might be one of the more DSP hungry effects on the Helix and the stereo versions of effects tend to use more DSP than the mono versions. I run a mono signal path and I could probably gain back a bit of valuable DSP with a mono reverb. Is this due to the fact that the reverbs were ported over from the HD500X? Are we going to be seeing any mono reverbs in the future?
