hello spirits in cyber land. i am searching for mac OsX tiger compatable software which will allow me to retune my p-60 so that i may learn both the sonata for microtonal piano & the suite for microtonal piano of the american composer ben johnston. i did find a software co. in vancouver who produced something called the justonic method but their code was written for the older mac Os9 & they didn't reply to any of my e-mails. anybody out there know anything about any of this?
