I use female RCA to male 1/4" jack adaptors. But considering I use the cable for all my ins and outs I wish I had used RCA jacks. Though one down side is RCA's will protrude out and 1/4" jacks do not.

The reason I use the Isolator for both ins AND outs is cause if you remove the cable from your amplifier while everything is powered on you can blow your SID, Furthermore even if you wait until all is connected before powering on your gear, some old (and even new) amps will create a voltage spike when powered on that could potentially be lethal to the chip. SID's are very fragile and taking every precaution to ensure it's safety is worth it to me. Especially after having blown 2 SIDs before.

They're only like 20-30 bucks on eBay. I've even found some as low as 12-15 bucks sometimes.

Good luck! and post photos when you're done! ;P

My buddy reminded me of something the other day that I thought I'd pass on to you as well. If you are planning on using the SID's inputs for injecting external audio sources like a laptop or CD player, it would be very wise to use a cable that has a Ground Loop Isolator, so the difference in voltage doesn't kill your SID. These can be found at radio shack easily. I use this one for mine. http://www.radioshack.com/product/index … Id=2062214

Hell yeah! Excellent work! This sounded great

Go to your Ableton's preferences and turn on the 'Track', 'Sync' and 'Remote' buttons for your USB Boy.

Hell yeah! that sounds sweet, Matthew! great job!

The ones I made aren't very jittery. That might just be due to the quality of the pots though... this I am unsure about.


I wanted to mention something else about the feedback mod that I just remembers. if you use a pot that has a pushbutton switch you can use it to ground the SID's audio input when you are not using the feedback mod. this will clean up alot of unwanted noise that the SID produces. Ideal for when you want to record pristine SID audio (provided you aren't using feedback in your track)

Two feedback knobs; One for each SID. You can prolly combine them into one or even use a dual ganged/stereo pot if you prefer less control over each feedback loop. No switch needed, 500k is plenty to prevent feedback from happening until you want it.

I personally use only one switch but it is only disconnecting controller port 2 so I can use a mouse. You can use a DPDT switch if you want to disconnect both pairs of pots with one switch.

The caps are AC coupling caps that block DC voltage.

If you just starting out theres no problem with the simpler mod for the pots. Sure it has the minor dead zone issue but if you feel like that bothers you later down the line you can always change it.

Use one: Routing external audio through the SID's wonderful filter.
Use two: Routing the SID's own output into itself creating feedback and more filer resonance.

That schematic you have is the simple and easiest way of doing it, but will result in dead zones where the value on screen is maxed out before the pot is fully turned to its limit. Again, it's not too terribly annoying or anything a definitely something that you could get used to. Many of us have accepted the dead zones as they don't impede workflow a great deal. The schematic I posted would have to be built twice for each controller port.

I haven't modded a c64 in quite some time now, but yes the pots, I believe, are wired up like variable voltage dividers. You just need to break power to those with your switch(es).


Also to touch on a few of your other mod quaries:

- Noise reduction with be very tricky on a c64 as most of it comes from the power supply, and then also I think a smidge from the video chip (I forget).

- Feedback pot and Audio outs can be wired like this (it's how mine is currently wired) :

I just tapped into the AV Port (shown in schematic) for SID 1's in and out but you can go direct like SID 2 if you want.

Yes sir. You shoud use this schematic for your potentiometers. Super accurate and no dead zones. Those submini pots are trimmers that you use to fine tune your dead zones away.


Also most of what you need to know has already been discussed in the MSSIAH-FORUM. I would just browse the old threads for what you need to know.

Great stuff. My only CC would be instead of remaining on one root note after your drop at around 2:00, I would have made the bass follow more of a dramatic chord progression, or any chord progression. But hey, I'm not terribly familiar with this sub genre of electro, so what you did might be exactly what is desired. All I know is that while minimal techno has a repetitive and commonly singular note bass roots, the textures and beat details change around it. In my mind at least I choose one or the other.

Take my CC as more of nitpick really cause this is seriously a face melting track.

Correct me if I'm wrong, but Gba should be the same as the dmg, right?

Nope. The amp is pre-pot. So if you solder to the pot you still have the amp messing everything up.
If you look up from the pot/jack area you will see 2 copper pads. Follow those traces back until you see 2 smd resistors.
Remove the resistors or just solder to the side closest to the CPU.
Sorry this is very badly detailed but I don't have an AGB in front of me right now.
Hope it helps!

P.S. No volume control.

These are so rad!

Might I ask what note that kick from Jelly Jam is on the MIDINES? I love the clickyness of it. Or if your just using a short burst of noise for the click.

I had some strange stuff happen using the save function as well. I just stopped using it and work on one song at a time per backup image. I would load a save and large sectors of the song would be shifted or missing. I think this was on rev2 a while ago. It also didn't happen often.

Did you ever get the backup I sent you working through TI Connect? I could grab the latest build and make a pre installed .82b for that if you desire. Granted it's only a temporary bandaid since you are having issues with tilp and/or TI connect.

I'd highly recommend getting a 32-bit version of Win XP or Win2000 running in a virtual machine. It's way less of a headache. I have all the tilp/gtk setup files and a pre installed backup image of houston you can try out. Forgive me if I'm not allowed to distribute these in such a way. If so I'll gladly remove. I just have no idea what the rules are.

GET IT HERE

Maybe if installing houston and crash from scratch doesn't work with TI Connect, You can attempt just using the pre installed backup file named "Houston Backup.82b"
