I tried to compare the same settings. The Prophet-6 is mono and bypassed the FX-Section. First example ist he Prophet-6, second the Prophet-5

I compared:
Brass
Unison Pulse-Bass with a bit glide
Pulse Pad
Pulse Strings
Oszilator 1 Saw
Oszilator 1 and 2 Saw with slightly detune
Both Oszilators Saw synced and unison
Oszilator 1 Saw Sweep
Oszilator 1 Triangle
Mixing all waveforms
Mixing Saw and Pulse
Mixing Saw  and Pulse unison and glide

In all examples there is no additional mastering, eq or fx.

I will make a better demo on youtube with subtitles hopefully soon, if I have time for it:-)

Prophet-6 compared with Prophet-5

I am a synthesist an I like vintage i.e. analog synths from the 70ies, 80ies and 90ies.
