Originally, I was longing to see the announcement of a similar software on the excellent Steve gadd site. Steve Gadd is a red-hot and brilliant user of those basic scales. The site has been built and it's still maintained by Stan Mulder. The name and the address are The Steve Gadd Site.
I've been awaiting during several weeks but nothing came. Then, I wrote it myself. When I finally contacted Stan to give him my little program he gave me the web address where was standing his. What a pity for me ! More, his program made more beautiful results than mine. I return to work to offer a better interface and much more functionalities. Rivalry is beautiful !
It is a while since this program trails in one of my directory and that it is useful to no drummer but before putting it on line , I had to polish it because it can be very greedy for resources (CPU and especially the memory) and it can blow its running server brains out. I took care of checking that nobody will be able to go beyond the interface and play with the server memory. I added a configuration file in order to allow the web-master to adapt the beast according to the server availability.
