No worries, I can send you a copy of one of the shows. Did 50's. 60's, 70's. hard rock and I think this week will be Latino Music as I just moved to Panamá.
Many keyboards have the option to change the pitch, to tune 440 Hz to 432 Hz you would go 31.9 steps down. Most keyboards don't show the actual frequency.
In order to tune instruments, you would want a tuner which allows to change the frequency. The KORG CA will do the trick.
