Analysis of Roland Juno60 sound
License: MIT License
Firstly, thanks for creating this repo. I am building a chorus plugin inspired by the Juno chorus and your analysis is very helpful.
It looks like you may have miscalculated the rate of Chorus II? (I haven't checked Chorus I+II)
In your analysis you show the rate as 2Hz, but your PWM Chorus 2 wav file looks like the LFO is completing a cycle approximately every 1.15 seconds, which corresponds to a rate of ~0.86Hz:
1/1.15 = 0.869 cycles per second
I have seen the figure of 0.86Hz mentioned on a forum someplace, which corresponds to that calculation.
And while I have your attention... :D Are you able to explain to me how you calculated the min and max delay times? I have found zero information about the LFO depth of the Juno chorus other than your analysis, so I am very keen to understand how you arrived at those figures.
EDIT: Ignore my last question. I can see that the offset of the delay is visible in the waveforms, so I assume that it is just a matter of measuring the points at which the offset is greatest and smallest.
Hi, the LFO rating at 15.175 Hz seems very suspicious.
We are making a Juno chorus and we have used your sound samples as a reference.
It has current source available and there is experimentation in our repository.
This is a rapid analysis of your 1+2 saw sample, and we deduce a completely different mod rate.
Prior to this analysis, I have deduced from a ear a similar rate, and the ~15 Hz value seemed to absurdly fast to be believable.
