The Sallytron machine is mostly used for the AlterEgo vocaloid VSTi, so it makes a lot of sense of put the Roland VT-3 Voice Transformer next to all of the other controls for Sally's voice. Which is why I've only just thought to do it.
Also, the Korg Wavestate stand can be adjusted in some very interesting ways, and then clamped to the rack as a highly stable interface for Wavesquencing 2.0 action.
