Sounds great.

Go to https://www.technologyroom.net and scroll towards the bottom of the page. There you will find a couple sound samples. There is also an email address for correspondence.

Disclaimer: Sequential has stated both on the GS forum and to me personally, that they will not provide support or repairs on any unit that has been modified in a manner not explicitly prescribed by them (which this mod most definitely does). The reason given is that they are too small of a company to be able to support user-modified equipment.

I can wholeheartedly vouch for and recommend this mod if anyone is considering it.  Randy is a consummate professional and excellent communicator, this mod is well-designed, and his work to implement and install it is top-flite (saying this as someone who could have performed the installation of this mod myself).  My Prophet 10 desktop is sounding better than ever (IMHO) and I am a happy camper!

Thanks!

There was a question of how to vary the stereo wideness with the Prophet 10 Rev 4. Was thinking some more and came up with a new one:

Here I have routed my Prophet's Raw audio input (recorded track) out to 10 sends panned different each with 1 of 10 ProEQ3 (Studio One) eq plugins.  Then each routed back into 1 bus and recorded on 1 stereo audio track for the simple 2 audio track recording solution.  It took me a while to set up the tracks and session and incorporate 10 extra sends each with a different panning and a different EQ setting.  Then I tweaked them a little.  Here you see a little of that and also using several different programs of the Synth during the 2nd half of the short video.

https://youtu.be/jLG6GpXGyMc

(but it is actually 3 (stereo) audio tracks I am recording because I always kept a 2nd direct input recording the prophet so there would always be a stereo offset from one to the other which worked for a long time.  It takes the same amount of disk space with 2 direct ins or with the 1 in, the group of 10 FX sends and the bus routed into a 2nd in.  With the light duty native S1 ProEQ which is an excellent plugin it doesn't do anything to the CPU I will wager.  Haven't tried it live yet but that is now a template so I will see.

I am just about on the first day of working on this sound but I found the results to be pretty good so far.  It did create different stereo wideness though I didn't work on it as much as I will eventually yet.  There can be a lot of tweaking still done and trying to get the far R and far L is still needed.  The difference in the stereo field and where the notes of different EQing were heard left to right, was pretty clear in my headphones.  Real nice effect.  I found myself wanting that I could somehow randomize the 10 EQ instances over the 10 different pan arrayed sends so that every time I push a 'randomize' button it would switch the 10 EQ instances into a different one of the 10 sends randomly or maybe just start the session with a different array.

Anyone else come up with this?  It seems obvious now that I thought of it.  Someone must have tried this at some point.

The only reason I record the 2nd audio track from the bus that mixes the 10 sends, is I wouldn't like to spend the same up to 2 hours or more of a live session recording this audio output from the sends, nor would I want to try to export a mixdown without first having the audio recorded from the sends so I didn't have to burden the mixdown with all the extra plugins.  So in this way when I would do a mixdown I would just mute the raw Prophet audio and probably remove it and its FX sends before mixdown (as it is, live, I have run it off into a FX send with the fader pulled down to silent).

Sorry, but I have to dig this up again  ;D

Is there anybody out there who already ran a P5/10 through the mono input of a Moog Matriarch to stereo-ize it and pair it with that beautiful analogue delay?

I'm thinking of selling my Matriarch at the moment... but perhaps I should keep it just for that? They could make a wonderful pair.

I don’t think this has been suggested, apologies if it has and I’m being redundant, but to take a page out of the guitar world (another mono instrument), a wet-dry-wet setup sounds glorious.  This is more of a “process” than an “effect”, and perhaps applies more to recording (it is certainly easier to do in recording).


Basically run your synth mono dry and in a parallel effects chain add stereo effects.  This has the advantage maintaining of a pure, unaltered, mono signal path.  When you immediately hit a stereo effect (chorus, flanger, phaser, etc.), the fundamentals of your original signal aren’t as strong.  The wet-dry-wet routing largely solves this issue.


In the guitar paradigm, you’d use 3 different amps.  One for your dry tone, one wet/effects left, and one wet/effects right.


So a dry mono signal paired with any number (or combinations) of stereo effects:
— chorus / flanger
— stereo phaser
— micropitch
— stereo notch filters
— slap-back delays


The stereo effects add width and space to a core tone that remains fundamentally rock solid.

That's how I do orchestral arrangements, but I duplicate the polyphonic version and mute the notes I don't want on that track.

I have installed the stereo extension and it's really great. I had to do it myself, since shipping the synth was not an option and Randall was very supportive. Instead of the external mixer box I installed it on the rear panel, which looks great and sounds really cool.

Best,

Steffan

Lately I've been inputting it into the Soundforce Chorus 6 module. Even with the chorus mix all the way down you can still have stereo output.

Another trick from the guitar-world (and I’m sure you can find synth examples of this from the 70s and 80s when synths and recording tools were a bit more limited), is to double track mono synths.
— Record a synth track in mono
— record the same track again in mono (a separate performance, not just a copy/paste of the first one)
— pan one left and one right
— the natural variance in performances will create stereo width and interest in the track.

I realized something about this (just yesterday), which is that it's just better to send all the right side eqs straight right only and the left side eqs straight left only.  This is because they all overlap frequencies and sum the frequencies so they may as well not be anywhere in the middle.
