Wrong. From the MIDI specification, it says clearly that the knob values can only be from 0-127. I tested this hypothesis by reading a hex dump of the MIDI data produced by me turning the knob back and forth. The knobs themselves are infinite, but at a certain point, it stops sending data.

my bad.

Then it's just a load of shit, these endless rotary controllers.

A brief read, and I do mean brief, in the Axiom manual:

"As mentioned in section 2 it is possible to assign the rotary encoders to any MIDI controller message listed in Appendix C. When the encoders are assigned to MIDI controllers, they work in the same way as the sliders on the Axiom 49 and 61�when the minimum or
maximum limit is reached, no more data is sent until you turn the dial the other way.
It is possible to program the encoders to increment or decrement the current value in the software, rather than sending an actual
value."

MIDI CC Endless Data Method Increment Decrement
145 Program Change Increment/Decrement � �

146 2�s Complement from 64 / Relative (Binary Offset) 065 to 127 063 to 000

147 2�s Complement from 0 / Relative (2�s Complement) 001 to 64 127 to 065

148 Sign Magnitude / Relative (Signed Bit) 065 to 127 001 to 063

149 Sign Magnitude / Relative (Signed Bit 2) 001 to 063 065 to 127

150 Single Value Increment/Decrement 096 097

151 RPN Increment/Decrement Message 096 then 000 to 127 097 then 000 to 127

152 NRPN Increment/Decrement Message 096 then 000 to 127 097 then 000 to 127

So... I don't know what most of that is, (and copying a chart from a PDF to a forum is obviously useless!) but I'm wondering if what you were reading (Chuckster) could have been a result of what midi channel it was on? Let me know if this isn't the case though, I'd like to know if it's otherwise!

Thanks,
Alan

Nice, then I was right !

This probably means Chuckster could take some time in configuring his endless rotaries
