Firstly thanks to everyone who bought The OP-1 eNotebook. Very much appreciated. The coupon for extra discount has another day or so and the sale price will remain till around end of Jan.
I have now released a FREE new eBook. This is called CHARTS and is a variety of charts, tables, references for music production. I hope you find it useful.
Hopefully it will evolve and expand but will be a free download.
find it here…
