The Ensoniq ESQ-1 and SQ-80 have a bunch of diagnostic codes that are listed somewhere at
, and are useful in
resetting and recalibrating the synths; and the Juno-60's are great--holding down key
transpose as you power up enters unison mode; putting a 1/4-inch connector into the patch
shift jack allows you access to 16 extra patches.
You can also buy new EPROM
chips for the Ensoniqs that will cause the machine to show a personalized message on
power-up. "Good morning, the next Rick Wakeman!" "More filter sweeps, Mister Hammer?"
