Is it possible to record the reverb output from the Impact twin, like it is on the Konnekt 24D?
No, this is not possible. The output of the reverb is not assigned to any of the FireWire lines as it's a native plug-in.
However, we do provide the M40 with the TC Near installation - this is a 32 bit native reverb, VST and AU compatible, that can be used in most 32 bit DAWs. Unfortunately the plugin is not 64-bit and cannot be used with the most recent 64-bit DAW's without using a bridge.
