When I first got my P10 and connected a sustain pedal to try release and hold modes out, my initial reaction was a preference for Release mode. The impact on playing cords and working the pedal was immediately nostalgic and reminded me of all those great vintage tunes made with the P5. At the time, I didn't even realize that the original P5 did not have Hold mode, but it occurred to me this probably had something to do with my ear's association between Release mode and that recognizable Prophet vibe.
I understand that these days, Hold mode is actually more popular (thus synths like the P6 and OB6 dont have Release mode). I'm glad to have the option, but I find I use Release more often.
Which do you prefer? Is the association with the classic Prophet sound and release mode all in my mind?
