SID Factory II build 20231002
The main feature of this build is a visualizer in the bottom left corner that shows dynamically updated bars for pulsating and filtering. Note that the background of the pulse bars gains the filter bar color whenever filtering is enabled for that voice. There’s also a new driver 11.05 with a pulse reset flag.

SF2Converter
The file converter is normally included in the latest build of SID Factory II itself. However, here you can find standalone downloads that has been released in between scheduled builds.
Extract the file converter into the same folder where the executable for SID Factory II is located. Open a command box and type sf2converter for info about running it.
See the text file in the archive for a list of the latest notes and changes.
Build 20200724 20200726

Download it here: SF2Converter_20200726.zip
Build 20200711
This is the official build of the converter with support for SNG files from GoatTracker 2.
Download it here: SF2Converter_20200711.zip A later build of SF2 now has a newer version
Why is there no ntsc version?
You can press Shift+F9 in the editor to toggle between PAL and NTSC.
Hi, thanks for this wonderful software!
Is there a way to input negative values for PWM or the filter cutoff?
I know on Goattracker you can hit Shift-N to negate values…
Adding 001 is +1 and FFF is -1, and that should work in both pulse and filter. Regarding the hotkey to negate a hex value, we’ve had it on our task list for way too long.
great job! I wish only one: when graphical interface 😉
Hi, is there a possibility to just try and play with the instruments without trying them by playing the song. I feel like an idiot for trying it so long now. But everytime i hit the note i am editing something…
Hold down Shift while hitting the piano hotkeys and it will play the instrument without typing anything. You can also hit Caps Lock to make the playing sticky, but this also enables editing of notes or tables.
will the editor also be extended for the Mega65 with 6 voices?
There are currently no plans to do so.
I believe Laxity’s next feature will be multi-speed support.
Hey, this looks super interesting! How low/high is the raster usage (CPU Time)?
It depends on the driver used. The default one is… about 24 rasterlines or so?
I can’t believe I just discovered this gem? Fantastic software and editor, and super thanks for the Mac Support! YAY! While I’m here, I’ll drop a quick thought: what if there was a 6-channel system with the classic 3 C64 voices, each paired with a ‘dither’ note channel? These would simply alternate frequencies with their master, adding a layer of complexity and texture through arpeggios. Just a thought to muse over. Thanks again for this fantastic tool.
@Andreas G.
The Mega65 has four SIDs, that would make not 6 but 12 stereo voices …. But anyway, would be great if this could be supported! Just run 4 reSid Emulators in parallel 😉
I would like to create a song that uses only two voices so that I can use the third voice for sound effects in the game I am making. How can I achieve this?
Unfortunately you can’t do that with SID Factory II. The drivers are not designed to allow asynchronous sound effects like that.
I believe GoatTracker 2 can do that.
