Missing Delay & Osc NRPN codes

[WytchCrypt]

Been busy mapping my midi controller to the P12 module 1.3 OS NRPN codes and noticed a few new parameters that I can't find in any docs.  Are there NRPN codes to control:

Delay 1 through 4 Feedback Modes (High/Low) and Oscillator 1 through 4 FM Modes (Linear/Exponential)?

Thanks,
Dennis

Its actually not terribly difficult to figure out! Hook your instrument up to your computer running a MIDI monitor program and see what NRPN numbers it responds with.

Alternatively you can get the information here:

Osc All FM Mode = 77

Delay Feedback Mode = 297

Delay 1-4 Filter Mode = 194 202 210 218

Beat me to it

Actually I looked in the table generated from the Prophet 12 information provided by DSI. Gross cheating as some would say!

Good advice everyone!  Hooked up good old Midi-Ox and got FM mode=77 and delay fdbk mode = 41.  I didn't realize these parameters were set for the whole group, I thought there were individual settings for each separate Osc & Delay 

I had no idea buying a P12 would be so educational

delay fdbk mode = 41

You are almost there but need to work on your NRPN understanding: Value = 128 * MSB + LSB. Applies to both parameter number and its value. And surely enough: 297 = 2 * 128 + 41. The rest is left as an exercise for the reader!

You may also want to read up on number systems. Letters are used for digits above nine: A=10, B=11 and so on.

Oh, I think I have a pretty good grasp of MSB, LSB, & Hex after the past week...

sysex $B0 $63 $00 $62 $0B $06 $00 $26 $01 sets NRPN 11 Osc1 Sync on
sysex $B0 $63 $01 $62 $3D $06 $00 $26 $01 sets NRPN 189 delay1 sync on
sysex $B0 $63 $01 $62 $43 $06 $01 $26 $7F sets NRPN 195 delay2 time to 255

Listing Delay Feedback Mode as NRPN 41 is not correct as noted above. Please check and recheck.

Oh and by the way: A sysex message is a specific type of MIDI message of the form F0 ... F7. The messages you are listing here are Continuous Controller messages. If you have time do spend a little time decoding the binary number tables in the manual. They describe the syntax of all relevant MIDI messages.

Proper terminology be damned...even if my explanation isn't technically correct, it works 

[dslsynth]

There are still stuff to learn if you want to know MIDI well. Hence the feedback!

Good to know you got it working.

The NRPN's sent out by the P12 for the advanced Delay parameters do not correspond to the NRPN's it receives for those. Is there a reason for this mismatch?

Example: Delay 1 Filter Mode sends NRPN 193 yet receives for NRPN 194
