Hi All,
On the PO-24 unit, the pitch of each sound seems to be represented by a value between 0-100. This differs to the other POs I have, in that they report the pitch of the note using the traditional musical scale (C, D, E, F, G etc.). Does anyone know how to equate the numeric value to its musical note equivalent? Not having much sense of pitch myself, I'm struggling to make the conversion...
Any advice would be greatly appreciated.
I don’t have this unit, much to my bitter, lonely regret. However I’d imagine that the 24 is like the 12 (being it’s younger, weirder brother of sorts)… The 12 sets pitch chromatically, and the way it is set is quite counter intuitive to me when aiming for “nice” sounding melodies. The visual representation of pitch is also under communicated by the screen on the 12, but the 24 seems to over communicate, if it displays 0-100… There are likely blocks of numbers per note ie. 0-7 = a, 8-14 = a#… Something like that…
Let me conclude by stating that I consider the 12 a drum machine with bonus melodic abilities, so it’s no matter that it doesn’t excel at easy diatonic melody programming.
Sorry I can’t be of more help, this is all just fun speculation. I’m sure someone who owns the 24 will chime in.
Hi ludicrouSpeed,
Hopefully someone will chime in who’s in the know. Have you tried the op-1 Facebook group?
I have both and in my understanding, the sounds that are able to give a pitched sound are just a few, but I haven’t tried to tune them to a specific note, I don’t think they are intended to do it, maybe just play with this as another variation
Hi All,
Ha! I was just working on this last night on the 24. This is what I have gotten so far for key 14(the bass note)
2:C 6:D 10:E 14:F 18:G 23:A 32:C 40:D 48:E 53:F 60:G 71:A 83:B 91:C5
Sorry for the gaps. My laziness. I was hoping to find a pattern. I thought there was on the low notes. Difference being 4 but the gap widens as you go up
Thanks a lot!
Thanks Tbcase, that’s useful What an odd pattern…!
