Thanks for the appreciation, guys. Without getting into the numbers, I can say that, whatever PWM patch I create, I use the same few standards. First, I use two LFOs for the PWM, each having the same depth but slightly different rates. A third LFO is used for vibrato, which is delayed using Env 3. (This is the reason the single LFO issue with the Prophet 6 and OB-6 is seemingly a deal killer for me.) Second, I set the PWM depth by playing the lowest notes I'll be using and making the depth as extreme as will still sound musical and properly tuned at that lowest note. Actually, I go just slightly beyond this point. This guarantees me a full five-octave range on the keyboard. Third, I set the modulation wheel to control the filter cut off frequency for dynamic changes, and I use this a lot throughout the music. Fourth - and here's the catch - the patch has to have a deep stereo field. Since I use a P'08 Keyboard in conjunction with a P'08 Module, I dump the patch from the keyboard to the module and then pan each instrument to opposite sides at the mixer. This is essential to the overall sound and gives it a spacious depth that a mono signal could only envy. Of course, you could do a four-voce imitation of this using the B Output jacks. I use this option on my other Prophet '08 Keyboard, even for mono sounds.
Without having the numbers, this will get you to the patch. Note that the recordings are all done live. I'm playing keyboards and bass pedals, mixing, and recording all at the same time. I actually think this contributes something very important to the music, which is somewhat simple, direct, and uncluttered as a result. And because I DON"T USE NO STINKIN' DRUM MACHINES, you get an excellent opportunity to fully enjoy the gorgeous sound of the synthesizer.
One more thing: the bass. Sorry, but the playing of bass on a pedalboard is essential to the overall sound. It completely frees up the left hand and guarantees a rich deep rumble throughout the music. I use five different bass patches for this, and I use them in accord with the dynamics of the music. It's one of the challenges of the performances and the reason I have to locate everything within reach. Since I usually end strong in the music, I usually finish with the biggest bass patch. I use an Evolver Desktop, which is controlled by a set of Hammond XPK 200L pedals.
Incidentally, there's an INHALT Youtube video that attempts to imitate the Oberheim sound with a Prophet '08. It's...okay...but when it comes to imitating a PWM patch, the effort just falls apart. It's a terrible patch. This mystifies me, because, in my opinion, the P'08 excels in this very sonic area.
And by the way, who's the inspiration behind my brass patch? It's Robert Schumann. In his Fourth Symphony, there's a brass section that has left a permanent impression on my musical mind. It's the very definition of "massive".
