Buenos Dias !

After a long strugle I got to the point where SEE doesnt use all 3 channels anymore.
Now my soundeffects are being played through PSG channel 3 only.

To make things easier I am not using the noise channel for the drums (SCC-blaffer) nor for the SFX (SEE).

So SCC-blaffer uses only PSG channel 1 and 2 for drums.
And SEE uses only PSG channel 3 for soundeffects.

However when a soundeffect is played there is a hum/hiss hearable in the background.
The drums (psg channel 1 and 2) keep on playing unaffected, but the soundeffect is being played 2gether with a hum/his.

When I mute PSG channel 1 and 2 in SEE, then still the hum/his is being played together with the soundeffect.
And ONLY when I dont play the drums at all (I dont call the SCC-Blaffer routine) then the soundeffect is played without hum/his.

does anyone have a clue where to look for the solution to this ploblem ?

kind regards !!! (ps, MIRC question: is there next to the rizon server another server for msx-channels?)

check if the NOISE channel bits are correct (overlapping?) reg 7 (iirc)

On Freenode there's #openmsx

And on Undernet there's an #msx as well

(not intending to put any other MSX channels down), I think both #msx and #msxdev on Rizon are the places to be for development related discussions though

yes I muted them (in SEE) completely, since Im not using them at all. Still there seems to be noise coming from SCC-Blaffer....

is #msx@undernet still active? haven't been there in months

Yep it is. Why don't you just check it out?

Then check SCC blaffer to see if they mask noise bits for none used channels!

i looked a bit and it seems the problem was scc-blaffer.
i changed somethings, and now it seems the buzzing is gone.

Now I added noise to the psg channels 1 and 2 (of the drums)
The sfx doesnt use noise at all (channel 3)
However, when a soundeffect is played the noise frequency is changed (thats strange), which is hearable in the noise of the drums (the drums, hi-hat and snare) start sounding either to high or to low....

Im almost there !!!

If I remember correctly the SEE replayer came with sources. Why not edit those a little so you can be sure there's no conflict between the SEE replayer and SCC blaffer?

yes I did. Because SEE normally uses all 3 psg channels. So what I did was change SEE source so that I uses ONLY channel 3 !!!
After that I had to change a bit in SCC-Blaffer so that it doesnt use channel 3 when a SFX is played.
If SEE doesnt play a soundeffect, then SCC-Blaffer will use channel 3 also (as an extra for the drums).....
