Can you change the filter type of an instrument 'on-the-fly' in SDI? I guess you can't yet? Is this planned for the next SDI release?
I really don't wanna resort to using Goat tracker cos emulations are crap no matter what anyone sez. |

You can't change filtertype on a instrument, so use a copy with another filter.
But, you can change the type in the 4th voice:
SEQUENCER FX + NOTE COMBINATIONS for channel 4:
-----------------------------------------------
FX NOTE
-- --- Empty line
06 --- [01-1F] Set tempo to 06 and no transpose
04 C#0 [01-1F] [C-0 to A#7] Set tempo to 04 and transpose 1
-- D-0 Set transpose 2
41 --- [40-60] Look up tempo program 01
44 FLG [40-60] Look up tempo program 04 and transpose 0.
70 --- [70] Filter control back to main filter channel
71 --- [71-7F] Force filter output
21 --- [21-3F] Force filter program 01
63 --- [61-67] Forced filter band 03
So, if you use 21-3f in voice 4, you can set any filter prg anytime you want.
And with 61-67, any type you want, any time. |

you also need to read this part of the manual, that shows how to set what voices to filter, if you dont use filter programs on the instruments:
INITIAL VOLUME:
---------------
If you want to change the volume or make the volume fade in you
can access the INVOL menue from the sound editor by pressing Shift+I.
c1 c2 c3
00:14 00 ;volume for song 00, FS = 00
01:0F 00 ;volume for song 01, FS = 00
02:F4 00 ;volume for song 02, FS = 00
1st column (c1) displays song number.
2nd column (c2) displays volume for the song.
3rd column (c3) displays Filter channel and filter speed.
The high nibble of c2 is used to set fadein, valid numbers are 1-F where
1 is the fastest fadein (0 = no fadein ).
The low nibble of c2 is the starting volume of the song, valid numbers are
0-F (0 = no volume and F = max volume).
Using max volume together with a fadein value will not produce any fadein.
The fadein routine will always fadeup to max volume.
Default volume for all tunes when starting editor from scratch is is $0F.
Filter settings:
You do not need to type anything in column 3 to make use of filter in the sound editor.
The high nibble of c3 is used to force filter on a channel when a tune is played from the beginning.
To make use of this function you need a filter instrument in one of the other channels.
0 = Filter force off
8-F = Future expansion
Force a single channel:
1 = Force channel 1
2 = Force channel 2
4 = Force channel 3
Force multiple channels into filter:
3 = Force channel 1+2
5 = Force channel 1+3
6 = Force channel 2+3
7 = Force all channels 1+2+3
The low nibble of column 3 controls filter speed delay.
The default value here is 0, which is the fastest speed delay.
This value is printed to screen next to "filter" and it is used to delay the
filter speed inside filter program. Each song can have its own filter speed delay.
At the moment its not possible to change this value inside the tune.
That is something for future expansion.
Valid numbers: 0 to F, where 0 is default.
Press ClrHome to go to current song's volume number.

Of course you can change filtertype. With the fourth channel. As Jan said, you can change filter prg there. An instrument in SDI is just a setup of programs, really. But there is a need of changing filtertype by frame. That is a must we've to implement in the next version. Bandpass between 10 and 30 doesn't make a huge click. But clicks can make some nice drums. |

I tried changing the filter type with the fourth channel and couldn't get to work, but I've just worked out that you have to set filter to 00 on the instrument/s you want to alter with the fourth channel :)

huh ? actually you need to set filter and bandpass/resonance in the instrument setup to have the 4th channel effect that instrument.

Em, nope. You need FLT program set in instrument though. (perchaps this can be overwritten witch 2x command, haven't checked)
If you use 6x on 4ch channel then the FLT band set in instrument is ignored. Either if it's 00 or otherwise.
If you use 7x then for packed tune it's important to start with command 70 on 4ch channel otherwise it won't work (works in editor though)
@Geir, do you plan to controll resonance with SDI v3 on 4th channel? |

Well, activating just the filter for the instrument might suffice for 4th channel control, i just set both out of habbit. |

Quoting Stainles SteelQuoting Linus
Don't get me wrong, I am not throwing bricks at anybody, but saying it's rock science is just bullshit. The sid *is* simple compared to more sophisticated synths
My friend, from your point of view that may hold true.
But then again, if it's no rocket science - why doesnt everybody's instruments sound as polished as yours or Jeff's f.ex. ?
Painless, I'll tell you how Linus's and Jeff's instruments sound so polished - they're spending a hell knows what deal of time trying to beat the shit out of the SID.
That's the "why?".
BTW. SDI 2b7 bugreport: the WF repeat doesn't work at all. Ie. the example below doesn't play as should:
Quote:WF REPEAT command (FA):
Must be used together with the jump command.
FA XX
XX = 01-7f
Tells the player to repeat
the following FF jump XX times.
When the last FF jump is executed
the player automatically jumps to the line
below the FF command.
Example:
00:FA 08 ;repeat 8 times
01:09 00
02:81 ce
03:41 a7
04:41 a5
05:41 a2
06:FF 01
07:21 00 ;ends here after the repeats.
08:FF 07
The FA command can be used together with all
the other waveform commands.

The FA command should be put after 09 00 (the init waveform), then the FF command should be FF 02 in this example.
Regarding your RETURN / SHIFT+RETURN Loop function on subtunes, I don't know. Has always worked for me. |
