Pea Hicks has recently overhauled his Optigan sample CD-ROM. Not only has Pea lowered the price to $100.00, he has added an additional CD-R with all the samples in the .wav format as well (the orginal disc is all Akai format BTW). And Pea has added additional samples of prototype Optigan discs. There are also some samples of a Chamberlin Rhythmate just for the hell of it as well. And finally, Pea says he has an Optigan software emulation in the works.
