ris8_allo_zen0 Posted August 2, 2008 Report Share Posted August 2, 2008 Hi all,I was wondering if there was a reason to set the left-right oscillators with a different wave type (left is Pulse, right is Sawtooth) in the default bassline patch.I discovered this thing when I checked my gear after expansion (now it has 2 stereo 8580's and one mono 6581) and noticed that in the default bassline patch the left channel's VU meter in my mixer was clearly higher than the right one. I started checking thoroughly all the audio wires and SID modules with no results. It was when I connected an oscilloscope to both outputs when I noticed the (quite obvious) difference in the wave shape.I can confirm this in the source code (sid_preset_bassline.inc, ca. line 45): ;; Voice #1 ;; Flgs Wave AD SR PW_L PW_H Acc Delay Trns Fine PRng Port. ArpM A.S/D A.G/R Res2 db 0x01, 0x04, 0x00, 0xc0, 0x00, 0x09, 0x10, 0x00, 0x28, 0x80, 0x02, 0x28, 0x00, 0x1f, 0x05, 0x00 [...] ;; Voice #2 ;; Flgs Wave AD SR PW_L PW_H Acc Delay Trns Fine PRng Port. ArpM A.S/D A.G/R Res2 db 0x01, 0x02, 0x00, 0xc0, 0x00, 0x09, 0x10, 0x00, 0x28, 0x80, 0x02, 0x28, 0x00, 0x1f, 0x05, 0x00 ^^^^ HERE IT IS Bug or feature? ;)Many thanks,RAZ Quote Link to comment Share on other sites More sharing options...
TK. Posted August 2, 2008 Report Share Posted August 2, 2008 This is an intended default configuration. You will notice, that most of my bassline patches are using the right-channel bassline with saw waveform in upper range.Best Regards, Thorsten.
