Have selected NRPN 14-bit - Now having problem with ratio between Master & Slave

MIDI Target Manufacturer(s): TC-Helicon
What I am trying to do is very simple but I am struggling, it's obviously me but I cannot grasp the logic of what is happening. Things only start going wrong when I exceed 0-127. I have set up a simple test, I created two controls (Knobs) I want them to be perfectly synchronized with ranges from 0 - 255, for MIDI as you suggested I used NRPN 14-bit for both and set MIDI ranges to 0 to 255, number of ticks is 256 ticks, have set one as Master and the other as Slave, however they do not work in a 1:1 ratio (more like 64:1), what am I doing wrong? also I only want one to send MIDI so how do I limit this ?

Thanks Lenny

The MIDI maximum for 14 bit is 16,383 which so happens to be 64 (63.99) when divided by 256, all the indications are that even though MIDI Max has been set to 255, that the absolute max is being used, is this correct? This would explain why I don't get the same problem at 0 -127 as the absolute max is also 127.
Hope this helps

OK, managed to get it working by setting the absolute maximum (16,383) for the master as MIDI Max, slave is still set to MIDI max of 255 now it's perfectly in sync hooray! not sure if it's intended to work this way though ? This only leaves me with my other less complicated question: In a master/slave relationship where you only want one control to send MIDI what do you set the other to?

Thanks

OK it appears that the Master does not send MIDI so good result nice and tidy, however now I have another problem Preset Selection (Knob) has two sequential slaves (also knobs) each of which is for banks 0 - 1 respectively, everything is set to only send on release, it would appear that both bank selection knobs send midi even when at their min or max position, as the last MIDI transmission will always be the control for bank 2 (last in sequence) this will always override the previous one. Any way of overcoming this ?

Thanks

Hey there, sequentials work the way they do, currently. In the future we may revisit this, thanks!
