Some compatibility/expansion questions

2 comments

I see it's a little quiet here in the forums, but figured I'd drop in...

 

Got the 4060 mk2 a couple of months ago and love it! Having a lot of fun, I love using it to control my 0coast in particular.

 

I just bought a Bastl Kastle 1.0, and it's a lot of fun also (although obviously not quite as open ended as the 4060). They both use the same jumper cables, but I wanted to see if anyone had any advice on using them together. Is there anything I should be watching out for concerning where I'm sending voltage? Do I need to worry at all about grounding? I also know that the Kastle can't take anything that might spike the voltage too high like a capacitor, but would there be a way to work around this? I imagine it would require using an expanded breadboard and figuring out a circuit...

Yes, I was indeed quiet in here until last night, when the forum got suddenly flooded with spam. So, I started to clean up the forum, and while doing it I realized there was actually some activity, and some open questions to be answered. So here goes:

 

Grounding the Kastle with 4060MK2's SLEEVE is a good starting point. You can do this with a juper wire or by connecting the two machines to the same mixer. If you have not grounded the two together, patching just one wire from a box to another will not be able to transfer a signal. Having said that you can usually send send signals back and forth by connecting two wires between the machines, without grounding them. The last mention is experimental though.

 

I quickly read what Kastle manual says about connecting external stuff, and it says the synth responds to signals between 0-5 volts, and that the signals will be rectified. I would still say, that the device can stand signals outside that range, since most modular synths produce larger swings. But that's just my impression.

 

If you want to be absolutely sure that your 4060MK2 will not produce larger signals than 0-5 volts, you can use a 5 volt wall wart. 4060MK2 will work with DC power from 3 to 15 volts, and will produce signals according to the operating voltage. Also make sure that the jumper in in the leftmost position (SLEEVE to minus). This will make the device unipolar.

 

I have used both 4060 versions with a bunch of different equipment and to my experience the current it can provide is so little that it's very unlikely to damage stuff. One simple way of limiting the current is using a resistor to patch the signal, instead of a jumper. You can start with, say a 100k resistor and try smaller values if there's not enough effect.

 

You can also lower the output voltage by forming a voltage divider with two resistors.

Thanks for this information..Very helpful. i have the 4060 MK2, the Kastle Bastl & a NanoSynth NS1 so i want to also make sure i don't feed anything in those units above 5V..is there a way to still use a 9v Battery and make adjustments on the unit and still have it output only 5V's?

  • I have been looking for something different in my Studio to generate Sci-Fi Noise to go along with my NanoSynth NS1 & Kastle Bastl since they share the same type of Patching Cables. So far i really like this 4060 MK2. It's a Must have for every Studio. I posted my 1st Video on YT. I hope you like.... https://www.youtube.com/watch?v=asB-zqcMWAc
  • Have any of you been using the 4060mk2 as a CV source? I am finding the possibilities to be endless.
  • Wanted to introduce myself. My olegtron 4060 mk2 just arrived and I am experimenting. Very excited about the prospects. I also have a koma field kit and am hoping to combine capacities for some acousto-electric experimentation. Hopefully more join this forum at some point lol. That is all for now
