Downloads...

Looks at mod sources.
Looks at mod destinations.

This is gonna be fun! :D

I liked seeing jamie lidell in the thanks section. Did he design some presets?

Indeed. One of my favorite live musicians, very glad I got to meet him and he was so excited to do a few presets for us. The ones he did are VERY playable and definitely hark back to the tone of the early Warp records. Really cool stuff

Thanks a lot for the manual!

Any chance I could ask you to post the standard presets too?

That would be soo nice! Thanks in advance!

:-)

I miss old school manuals where they show u patch sheets of how to make different instruments

What is the "DC" modulation source?
DSI: Evolver #1431, previously Mopho Keyboard and Desktop Mopho
Hardware: Moog Little Phatty Stage II (Red), Arturia MicroBrute, Korg Volca Beats
DAW: Reaper for OSX through PreSonus AudioBox USB

This is just a fixed value. You can use this to control the modulation.

For the wave table you can modulate between 3 of them. But what happens if you only modulate between the first and second? By adding a DC source you can offset the modulation so it only goes between waves 1 and 2.

e.g. If the modulation goes -100 to +100 It'll go across wave 1, 2 and 3.
You add an offset of -50.
Change the modulation to -50 to +50.
The modulation and the DC add together so the end result is a modulation of -100 to 0.

Once you understand it it's easy to use and very powerful.

Is the index of the Prophet 12 program parameters the same as their NRPN number?

The Prophet '08 manual has the exactly same description. And hence does not describe the location of the program parameter indexes only the NRPN parameters. The Tetra Combo format table is even more challenging to decode. Fortunately the Evolvers, the Tetra Program and all the Mopho variants are very precise here.

Just wanted to express my wish that DSI clearly states this essential information in their manuals. The overall quality of the MIDI specifications for DSI instruments are always very high and some of the best I have seen. But as with all language descriptions its important to get all the details right.

A checklist for description of program parameters is: name, program vector index (aka parameter number), value range, value description, optional CC/NRPN controller numbers and optional sysex parameter change message format.

Speaking of controllers: some parameters has both a CC number and more than 128 different values. Checking the relationship between CC message values and the parameters value is fairly simple with software once one has access to the instrument. But that case is not documented in any of the DSI manuals.

I've seen all those interesting features of the new OS versions. Are they already documented somewhere? At least in a rough and ready manner?

Hi
This manual has the next errors:

1.- Appendix A: Modulations Sources: Missing "27 Audio OUT"
2.- Appendix B: Modulation Destinations :Missing "25 All OSC Slop"
so destinations numbers after 24 are mismatched by 1.

Ergo,sources are 0-27 not 0-26 as stated and destinations 0-98 not 0-97 as stated.


So be careful while programming NRPN.

Cheers

Czech translation updated with Addendum v1.1 and finished (if anyone interested in). Maybe DSI adds link to it into P12 webpage as I had sent all information to Mark Kono (as with the first manual version in the past).

Cool wanted to know that, couldn't find it in the manual! what.

What I'd also like to know is the conversions of the parameters from 0-127 into their real equivalents, such as the frequency of the cutoff, the rate of the attack on an env, etc, etc. where can I fin that info?

For the dealy you can find this table near the end of the manual. I believe it's an appendix. The rest I haven't seen anywhere. Possibly on the screen.
