i was consider the idea of tricker 2 or more programs, but some time you can run more than one, other time it don't work.
so i think the only way is to add more channels.
i am not sure that i remember where i learn i from, but some of the things i learn from a Danish book about synth, other thinks i found out by my self, some was one of my friend that told me how he wanted the tracker (eg. no pattens score) , but it is so long ago, i think i started around 1985-1986 on the MSX home computer,
my first music program for the Atari was a midi program made i GFA basic. patten based.
but many of the thing that is in my player you can track back to my early trackers, on how i made my bend routine work.
i have never use the internet to finds ways to make my players/editors, i have only use it to find specifications on the hardware.
but i use the internet alot these day to help me program in windows, i forgot the most after 11 years of absent
btw. i also got few good idea here
