Quote: In the saved prg/sid file from GT 1.52, you can mask out the volume either by changing the value at $106E to $2C, or you can put three NOPs at $106E. This is easy to do in VICE or in CCS64.
If you have a hex editor, change any occurences of 8D 18 D4 to either 2C 18 D4 or EA EA EA.
This will mask out any volume settings in the SID.
Goody, I will try that when I'm home.. thanks for the tip. |

If you knew assembly language it would have been (with IRQ) something like this (only sampling for old SID, as I don't know how to cater for new SID):)
SEI
LDA #<IRQ
LDX #>IRQ
LDY #$7F
STA $0314
STX $0315
STY $DC0D
LDA #$01
STA $D01A
LDA #$00
JSR $1000 ;Init goat tracker tune
LDA #$00
JSR $9000 ;Init Digi-Organizer module
CLI
HOLD JMP HOLD
IRQ INC $D019
JSR $1003 ; Play music
JSR $9003 ; Play sample
JMP $EA7E
If you need me to code this little player for you then I be happy to help, all you'd need to do is just mail me and I will quickly come up with the player for you. |

you can use even filter (low pass) into Goatracker: check SIDin #6 the article about Digiorganizer (used with Goattracker) |

This does not seem to help much. Only tiny improvement. With long notes, the volume keeps fluctuating on the rythm of the sampletrack.. |

Could someone write a tool (PC or c64), that combines digiorganizer modules with normal SID - without writing any line of code? |

Stephan, it's always the same piece of code. I can precompile it, so you can easily slap it in front of your tune with a hex editor. |

Hi, Stephan
good idea!!!
or maybe someone could progamm a digi-routine for GT?
Since GT is one of the easiest Tracker, also less experienced people could compose cool 4th-channel sound....
Out there are so many skilled coders, right?

GT could even use digiorganizer , the problem is that Cadaver then would have to make serious changes in his code. anyway if we speak about digis it would be cool if the player could be easily switched to play samples using DAC connected to userport for example (Actually even simplest DAC build using resistors gives acceptable sound quality , and you can use filters then. real DAC using for example DAC808 would be brillaint when mapped somehere in addy space , so you can have UP free for something else, DAC808 has got maximum sampling f at 10khz but I heard it can easily be "Boosted" to 20khz) - but there are surely people against it (how many sceners own a DAC or UP sampler with DAC?) |

nata: Yes, there are tons of skilled coders who are just waiting for someone to come up with some random coding project for them on some forum. |
