[MSX] More PSG doubts

[Eduardo Robsy Petrus]

Hi!

As far as I know, Flying Bytes' PSG Tracker was coded by Diederick de Vries (programmer of Meridian) and I have seen his name in this list. Could you tell me, if you remember it, what does the BEAT ON/OFF feature do? I haven't heard any difference at all.
I am reprogramming that tracker (I love the controls and it is really easy to use) and a brand new replayer using a more compressed file format. At the moment, the replayer supports 8 octaves, channel detunning, volume variations, pitch bend, envelope shape changes. I cannot implement that BEAT ON/OFF because I really do not know what it does exactly. And at the moment, I use only 128 different combinations: there are 128 combinations more (to fill a byte) to add different effects, like vibrato and tremolo.
That will do one byte per channel and an extra byte for controlling the white noise: that's 4 bytes per entry. Replaying 10 entries per second, that will be about 10 KB for a 5 minutes song.
Any suggestions will be welcome. After finishing the tracker and its replayer, I am planning to add SCC support.

Thank you for your help!

Kind regards,

Ed Robsy
