Please help! Every 13th-16th note sounding different?

[edsynth123]

Firstly, apologies as I'm not the most well-versed in analog synths. I have a Prophet Rev2 16 voice running the latest OS (1.1.0.3). I've recalibrated the voices, reset the globals, etc.

I've had a problem where certain patches make different sounds every 13-16th key played. So, for example:

1hit, 2hit, 3hit, 4hit, 5hit, 6hit, 7hit, 8hit, 9hit, 10hit, 11hit, 12hit, 13different!, 14different, 15different!, 16different!

I've attached an example of my prophet - from both U2 P82 Candian (with unison, glide and effects turned off) and U1 P1 LosVangelis2041. My friend also has a Rev 2, and I got him to do the same for the first preset - with exactly the same settings, though maybe he played his note slightly harder. 'Normal' example attached. We also went through the globals and misc and we both had the same settings.

I really have no idea what's doing this - please could someone help? It's so frustrating as certain sounds I want to use/build on become unplayable as every time you play you're just waiting for the next note to sound weird. I hope it's not broken, though I wouldn't be surprised if it's something super obvious that I'm completely oblivious to. Any other info you need please let me know.

On your example, the last four notes seem simply panned 100% to the right.

I've tested on my REV2 and all notes are centered.

I would contact DSI support about it, as this doesn't seem normal behavior.

Thanks for checking it too - really appreciate it. I'll contact DSI.

Could it be an LFO or the Aux Envelope changing the sound? It’s a long shot if it’s happening on more than one preset I must admit though!
