Unexpected RPN messages when using NRPN controls?

General discussion
1

anyone an idea as to the cause of this?
More often than not when the preset on the Novaton Summit (Electra One App) is supposed to send an NRPN message, it does not only send the expected 4 MIDI messages

  • 99 (NRPN MSB),
  • 98 (NRPN LSB),
  • 38 (Data LSB) and
  • 6 (Data MSB),

but it is followed by

  • 101 (RPN MSB) and
  • 100 (RPN LSB),

and those last two are not expected …

The example below shows the result on Midi-Ox when turning ‘FX Dry Level’ control on the performance page

hi @NewIgnis, these two RPNs are to reset the active controller. It is common practice to do so. see MIDI NRPN and RPN by Phil Rees. Does it cause any issues? Pls let me know.

Ah, I didn’t know that. Never knew that CC100 and CC101 on value 127 was considered as a closing instruction for the last NRPN parameter. Thanks for the info , @martin .

I further checked the issue I had, and can confirm it is not related to the RPN transmission.
Case closed.

Hi Martin,

For some synths it may indeed be problematic to send the additional RPNs, which is why it’s great to now have the “RESET NRPN PARAMETER” check box to disable it.

However, I think there may be a problem with the value the Electra One App editor shows for the checkbox value. If I set it to NO and send the preset to the e1, it works as expected and the RPNs are no longer added. However if I click on another control, and then back on the NRPN control for which I set the checkbox to NO, it now shows the default YES again. But resending the preset to the e1 from that state doesn’t re-enable the RPN messages. To do that, I need to toggle the checkbox off/on again and then send the preset. Presumably just a matter of the editor not correctly reading the checkbox setting, so hopefully an easy fix.
