Analog Four Mk1 Filter Encoder Behavior

Elektron Gear Analog Keys/Four

Hi everyone,

I am trying to determine if I have a problem with an encoder on my A4 Mk1. The rotary encoder is the upper left one, which controls the LP filter.

If I move it “very” slowly, an additional graphic appears on the screen. It looks like a dark smudge that rotates around the edge of its circle symbol. What does this graphic represent or mean - is this dark graphic symbol explained anywhere? Then if I begin to move the encoder a “little” quicker the graphic disappears…

(Regarding it becoming faulty, I think my encoder might be going bad as this dark “smudge” graphic appears occasionally at different speeds, and the knob values stop responding for a second or two. As if it freezes up)

If anyone understands what this symbol means, I would be interested in hearing!

Thanks in advance. :grin:

it’s normal, absolutely nothing wrong - this is shown on many dials that have 14bit range, it crudely shows the extra depth beyond 7bit (the integers displayed 0-127 typically)

Thanks for pointing that out. I wonder if it’s mentioned in the manual, as well as its relationship to the knob movement? It’s so delicatedelicate an action that I have trouble understanding how it reacts to knob speed…I want to make sure my encoder is OK or if it’s becoming faulty.

whether there’s erratic data being generated is one thing, you’d have to use a midi monitor to spy on that - if twisted consistently and slowly there should be 127 incremental steps between each step value shown on the numerical display - each nrpn is made of four CCs so you need to monitor the one varying most rapidly - it should be possible to scroll through that range if you do so slowly with precision, if you go fast then the OS interprets your input differently and accelerates advances

afaicr, the additional dial graphics should show a clean sweep around but in a vastly reduced resolution as the dial is made of a few pixels - it’s definitely going to be mentioned in the manual imo

Thank you - I will investigate further and check out the manual. I appreciate your reply!
