Roland Alpha Juno Chorus Compared to the legends: JUNO-6, JX-3P, JX-10, JU-06A (60 and 106 models)

The Roland Alpha Juno 1, 2, and MKS-50 have the same legendary BBD chorus chips as the rest of the 80's Roland classics, with one major difference: variable chorus rate! I've gone through and mapped out the actual chorus rates of all possible values, from 0 to 127. I've also measured the chorus rates of every Roland synth I own, and found which chorus rate values on the Alpha Juno best align with each of them. This includes the JUNO-6, JX-3P, JX-10, and JU-06A, which has built-in JUNO-60 and JUNO-106 emulations.

If you are interested in hearing how the chorus on the Alpha Juno compares to the other Roland giants, then this video is for you! There's a small section at the end that shows how I measured the chorus rates, so you can do the same.

This is not intended to see how the Alpha Juno stacks up overall sound wise against the others and there is no real patch matching. That would have taken way too long, and this video is already long enough. I'd suggest heading over to Starsky-Carr's channel if you're interested in that sort of thing (his Alpha Juno vs 106 video is definitely worth the watch).
