I now remember what bugged me about the OB-8 that also continues with the OBX8. Left side of the control panel is ergonomically crippling: the position of the master volume and the portamento controls. Strangely, these two knobs are located the furthest away and often uncomfortable to get to during a live performance. It must be an Oberheim ritual because it stems back to at least to the OB-X.
It would seem logical to swap the position of the Master Tune knob with the Master Volume; as well as, swapping the position of the Portamento with the Osc 2 Detune.
Question: how many times during a live performance do y’all need to adjust the Master Tune? Actually, that’s one control I don’t readily need on the front panel. I’d hide that under the Page 2. And, probably only seldom I have ever re-tweaked the Osc 2 Detune once I have programmed a patch. But, needing to adjust the master volume and adjust the portamento rate (especially during unison solos) is quite regular. I commend Dave Smith of the placement of the Glide knob on the Prophet 5/10.
