Modular Diary – 022

Here’s a quick comparison of the differences between the Equal and Analog tunings on the ARP ODDYSEi – and how they compare to strict equal temperament. I’ve only measured one octave up from A = 440 Hz and am curious to measure how the tuning behaves in the other octaves as well. Interestingly I had to set the master tuning to 437.6 Hz on the ARP in order to get a measurement of 440 in Audulus. And the analyzer in MC Studio is showing pitches roughly 4 Hz below the equal measurements taken with Audulus. I’m not sure what’s going on there. Something to look into.

Equal Temp. ARP Equal ARP Analog
440 440 441
A# 466 466 468
B 494 494 496
C 523 524 526
D# 554 555 557
D 587 588 591
D# 622 624 626
E 659 661 664
F 698 700 704
F# 740 743 746
G 784 787 792
G# 831 835 840
A 880 884 890

The next step is to calculate the deviations in cents.
