Emax

One of my "interesting" memories with my emax...when it was relatively new (pre-SE, pre-HD), I turned it on and all audio-hell broke loose—had to scramble to turn down my mixer. It had worked before so I thought about what had changed—disconnected the (sustain) pedal and powered it back up—everything's fine. Plugged the pedal back in and it's fine. But power it up with the pedal in—loud, horrible noises (sadly, not musical ones, or even interesting ones). They had just done an OS rev that was smart about sensing the pedal—it would take either a normally-open or normally-closed pedal, sensing the orientation when you plugged it in. Runs in my mind I was using a yamaha pedal that was normally closed (from DX7?). I reasoned that they had neglected to test that type of pedal when it's already connected at power-up. I called them, and sure enough they had no idea—but thanked me for figuring it out, and fixed it in the next rev!

The manual says the pedal input receives standard CV signals but here's what it does for me: even if the pedal input is not assigned to anything in preset definition, when I send a CV signal, the display jumps around different submenus, on the main page it jumps around presets and when the cursor is on some parameter to adjust, it changes the values, so basically it does the same job as the DATA slider.
