Title: Is this possible?
Post by joglee on Dec 26^th, 2022, 1:40pm

Hello,

I've got this old Wersi OX7 Virtual ToneWheel Drawbar Module and I'm trying to control the GSI VB3 software organ on my PC. The VB3 is corresponding to whatever CC# I set, but the Wersi module is sending 3 MIDI messages for every event;

NRPN MSB 63 always with value 0,
NRPN 62 LSB with a value between 00 - 08 depending on which of the nine drawbar I'm moving,
CC#06 with a value between 00 - 7F depending of the position of the drawbar.

So my question is if its possible to translate these 3 messages to only one unique CC number message?

Appreciate any help I can get

Thanks!
Glenn from Sweden

Hej Glenn

You can do it even with only the MSB of the value
Go to the Mapping area, clear it and insert a new line...

I'll assume (for no reason other than this example)...
1) the Wersi is on channel 1 and the the VB3 is on channel 2
2) NRPN numbers 00 to 08 should create CC types hex 10 to 18

The mapping
Input
Chan 1, Event NRPN, NRPN# Min 0, Max 8, Value Min 0, Max 16256
Output
Chan 2, Event CC, Ctrl# Min 16, Max 24, Amount Min 0 , Max 127

Don't tick any of the boxes (except the "Turn Map On Later' if you are wanting a map for all connections).

Don't forget to save it.

The first number (the NRPN number) is translated on a one to one basis 0 -> 8 to 0x10 -> to 0x18

16256 in 14 bit hex is 7F 00.
MidiOx assumes the LSB is 0 if it doesn't receive it, so 16256 enables the scaling to 0 -> 7F for the for just the MSB value to work, otherwise it would only go to 7E.

If you are new to the data map and need some help with setting it up let me know.
