Has Anyone Modded The P10 So It Has Stereo Capability

[seqpro3]

I’ve always thought the P10 would benefit from stereo outputs since it has 10 voice polyphony and has the ability to do splits and layers. I saw on a forum where someone had modded their P10s headphone output and gave it stereo capability.
Wasnt sure what would be involved. Thanks  🙏

I modified mine.
I couldn't imagine split and stack mode coming out of a mono output, so I searched online and found a kit to separate the outputs, using the headphone output.
It's not easy; you need to have a professional engineer do it.
In stereo stack mode, it sounds huge; I use it a lot, even with the same sound slightly modified.
In split mode, you have the two voices separate; in normal, the sound changes depending on how many polyphonic voices you play simultaneously.
For purists, even the original Prophet 10 had two outputs.
The consequence of this choice is that modifying it voids the warranty.

Would be cool if Sequential offered a stereo upgrade kit....  It would definitely sell. 

Sequential - everyone would probably buy one.

It would be great if a stereo upgrade kit was offered. The P10Rev4 would greatly benefit with
stereo capability. It would rival the OBX8. I have a OBX8 and the reason I chose it over the P10Rev4
was because it was in stereo.

Did a search. Couldn't find anything. Do you think you can share the link to the stereo output kit? I wanted to give my business to sequential. But I do not think they are going to offer this upgrade. Really appreciate if you'd share the link to this mod. I'm going to buy the additional 5 voice board; and as you. I couldn't imagine using the split and stack modes in a mono output.  Thank you in advance.

What you want to do is get a Stereo synth.  There is a possibility I don't know what you think, to use the DAW and just use its sends to channel your synth here and there throughout the L-R field.  I do that in my base template so it always comes through.  Here I have a video I made about 2 3 weeks ago and posted on Rumble.  This is about 10 minutes I think it's a good bit of Prophet that's why I uploaded it.  You should notice it's really a stereo sound.  This is all done with those 10 sends in my DAW each having a different EQ focusing on a different frequency.  It's a lot different than a basic Mono would be.

Changed DAW settings and ran that Prophet out from the 'stereo-ized' prophet into a pair of outs I rout to one of 10 oscilloscopes I run that I have set up to stereo to usually show one of 2 VSTs.  So you can see the difference between the L & R channels is pretty significant even if it doesn't sound that much different.

For using the oscilloscope I run the L & R out of the daw, out a patch cable and back in to another interface or pair of ins and it is seen here the two tone blue active oscilloscope for most of the video  https://rumble.com/v75elyc-a-little-heavy-music-feb-6-2026.html

I usually run about 11 oscilloscopes (each set accordingly via from the ins that bring the audio for every different instrument or VST) but in this video because I am not playing live but mixing and watching the daw I only use the prophet 10 stereo oscilloscope for the video.  I'll probably keep it this way.  I may switch up the replaced VST onto that Drum track oscilloscope (who needs an oscilloscope to a drum track).

A very simple and effective way to achive a stero P5/10 is to record same thing twice and hard pan left and right. The sound moves enough to get a stereo field.

Especially if it's literally 2 different takes of the same... old school multi tracking like that actually ends up sounding better most of the time due to small variations in playing on each side and is why a lot of older tracks sound so good.

The benefit of this approach, compared to other stereo-spreading techniques (except voice stereo spreading), is that the phase remains intact, ensuring it sounds good on any sound system.
