Prophet 5 - 40 first

Henrik · Post by **Henrik** » Thu Jun 22, 2006 4:03 pm

Hi,

I took the first 40 original patches of the real Prophet 5 and entered them with BCR2000 to Noah.

A few notes on what I had to change:
Glide on the original are not effective unless UNISON switch is set on. On Noah the Glide is not disabled by UNISON switch. So for all patches with UNISON off I had to set Glide = 0 to make the sounds resonable.

Poly-mod Filter Env goes from 0-10 on original but (-?)5 to 0 and to (+)5. Center value (64 through CC#) is 0 and gives no modulation. CC# 0-63 seems to be a feature of Noah not on the original. 64-127 or 0-5 seems to match with 0-127 or 0-10 on the original so I converted all original numbers like this:

Poly-mod Filter Evn = 64 + (original/2)

Last thing I did might not be right: Modulation Wheel in full position sounds silly if FRQ A or B is selected for Wheel Mod. So I chose something near 2 instead of 10.
For PW and FILTER I chose 10.
This is purely my personal taste. Please comment

I notised that max value on original is usually 120 and not 127. This might mean that we need to scale some controls accordingly.
Also the Pulse Width seems to be reversed on Noah. However I used the numbers directly. PW of 59 or 60 seems to be center on original. I don't know yet what to do about it.

I have no idea how the original presets sounds on the real Prophet 5 but here you are. A first shot.
After some feedback I will finish my PC program which converts original SYSEX one by one to the Noah for the 80 remaining Factory patches and 2 extra sets of 40 that I have found on the net.

So now please play with them, adjust them and give some feedback. Escpecially if you have the original P5

Then perhaps you could provide a few sound-samples of the original sounds.

Henrik.

Wow, a real maniac!

To be honest, until reaching the last paragraph of your post, I believed you had an original p5 for a/b-ing the patches.

But I'm curious to try your sounds out.

Thanks,

Today I digged into the Pro12 frequency knob because I had the feeling something was "wrong". Somtimes things sounded wrong when I simply used the original Sysex numbers through Midi CC# with BCR2000.

Analysing the Prophet 5 schematics and sysex files it seems that the knobs always goes from 0-120 with 60 in center. However the frequency knob reading are send to D/A converter without bit 0 so in reality it goes from 0-60 with 30 in center just as Creamware has implemented it

Examples from original patch sheet
Sysex data 0 = +0 octaves

25 = +1 octave
31 = +1 octave + a minor 3rd
38 = +1 octave + a perfect 5th
49 = +2 octaves
73 = +3 octaves
81 = +3 octaves + a major 3rd

However Midi CC# goes from 0-127 so how do they correlate with the original Prophet 5 controls?

Some nice Noah UI shortcuts to know:
------------------------------------
Go Center (double click the Frequency knob with the mouse. Double click again to go back to previous value)
+1 Page Up
-1 Page Down
Max Home
Min End
Use these to get accurate control instead of turning the knobs with the mouse.

Frequency knob control goes from: 0->30->60.
Midi CC# goes from 0 - 127

Knowing this I can make the conversion table
for the Frequency knob. Each Pro12 step is a semi tone.

118-119 59 124-125 B
120 60 126-127 C+5 octaves

So now I have to correct all the 40 first patches' frequency. I'll post it here when I am done.
This also explains why some patches sounds really strange.

Hi Henrik,

Would it be possible for you to share your BCR2000 templates for NOAH Pro 12.

I intended to build up one but perhaps I should try yours...

Cheers.

Sure I'll post them as soon as I come back to Denmark. I'm in Kos Greece right now.
