What are the differences between "Detune" on OB-6 and "Slop" on Prophet-6?

I use Slop on my Prophet-6 all the time. I am wondering how exactly the OB-6's Detune function differs (if at all)?

Just to be clear, I am asking about Detune in poly mode, not Unison mode.

I think the answer is "nothing".  I recall hearing Dave say in one of his demos that the "Detune" was called "Slop" on the Prophet...  And the descriptions in the respective manuals are identical.

Here's what the manual says:

Detune adds randomized detuning to the oscillators to emulate the tuning instability of vintage analog oscillators. This tuning instability is a big part of what made vintage instruments sound characteristically warm and fat.

By comparison, the Prophet 6 Manual says this:

Slop adds randomized detuning to the oscillators to emulate the tuning instability of vintage analog oscillators. This tuning instability is a big part of what made vintage instruments sound characteristically warm and fat.

*** Disclaimer:  I have quoted manuals before only to find out later that I was wrong.

Based on your assortment of DSI synthesizers, you'd be the ultimate person to describe the similarities and differences between instruments.  I'm always interested to read in-depth comparisons.

I haven't really compared them in that way, but I'll get on it...

In poly mode, Slop on the P6 and Detune on the OB-6 have exactly the same implementation. With unison enabled, Slop on the P6 doesn't differ from its implementation in poly mode; in contrast, Detune on the OB-6 functions as a unison detune, providing a fixed amount of detuning, versus the randomized detuning of Slop.

i think carson or maybe dave himself stated Tom didnt want the word "slop" used on his instrument, so "detune" was chosen.

I am noticing one thing that differs between the two. For an example set up an init patch on both. 2 sawtooth OSC tuned to unison. Hold down only one key and start to adjust detune/slop.
On the Prophet 6 the oscillators start beating against each other but on the OB 6 the oscillators are detuned in the same way so they do not beat. It sounds more like you adjust the pitch wheel very gently. Based on this, it does seem that slop affects the individual oscillators whereas detune affects the voice so you get more drift between the voices instead of the individual oscillators. Is this correct?
