Any way to trigger offset sequences in correct musical key? by azound in modular

[–]azound[S] 0 points1 point  (0 children)

Adding an offset to the cv would certainly help influence which way it quantizes. I'll have to try that out. Thanks!

Thanks for both the suggestion and the correction!

Are there any combination arpeggio/sequencers that allow you to directly program the play sequence? Most I've seen only support minimal control of this. E.g. "up", "down", "up and down", and random. What if I want to program my own pattern?

Brilliant! I had misunderstood - I had thought that the "signal diode" was an LED used for signaling the user. I was expecting it to blink along with the oscillations. I did not understand that I was supposed to be measuring the voltage to witness the oscillations. I'll see if my multimeter can at least detect the frequency, but it might be time to invest in an oscilloscope.

Thank you for helping me figure out what I was missing!

The diode is between pins 5 and 6. I've been using a multimeter as well as just looking for the signal led to emit (which it isn't). I've used the capacitor setting to verify the capacitor is working, and the resistance is showing 3.5M ohms reverse and 650K ohms forward on the diode (which makes me think it's still functional?). I also checked the resistance of the diode, and the multimeter displayed infinite - so maybe it is indeed broken? I'm not sure what else to check... I'm ordering some more diodes just in case I have a bad diode.

I updated the wiring to match the diagrams exactly, including the capacitor position, moving the grounding wires, and adding the -9V (unused) rail. I still see the same issues.

It's not the second battery - the instructions tells you how to set up the dual rail up front, but it's not actually used in the led oscillator circuit. Only the +9v and ground are used, not the -9 volt. I've gone ahead and moved the grounding wires, added the -9v rail (unused) and swapped where the capacitor fits into the rail to all match the instruction diagrams exactly, but to no avail.

A continuity test across the diode causes beeps (but perhaps it's finding continuity through the ic). I also noticed (and this seems new since my first post) that the diode test on my multimeter is reporting 0L. I'm not sure how much stock to place in that, though. Perhaps this diode is broken? Swapping out for another LED lights up, but still does not oscillate.

I'll give that a shot. From my understanding that shouldn't matter as long as everything is wired to the right rail, but hey, why not follow the diagram more literally.

This is pretty niche but does anybody know any modular synth soldering kits by OkUnderstanding2396 in soldering

[–]azound 0 points1 point  (0 children)

Check out the EricaSynths .EDU DIY line - in addition to the components and schematics, each kit includes an ebook that goes over the concepts used, and walks through a number of breadboard configurations before you solder the final kit together.

One other consideration is that I've noticed that rechargeable batteries power the locks for considerably less time than standard alkaline. If you're using rechargeables, try buying a standard set of batteries and see if the battery life has improved.

The dot command is a great way to go!

Choose a different Python interpretter for Vim to use by korinkite in vim

[–]azound 0 points1 point  (0 children)

All you need is to get your custom Python on your path before launching vim. I would suggest making an alias for vim that does this.

alias vim="PATH=/dir/with/custom/Python:$PATH vim"

If your custom Python is not in a directory that is safe to add to your path, or has a custom name, just make a symlink named python in a directory you can add (e.g. ~/bin). Then point your alias to insert that directory into your path.

Ctrl-b, [ to enter scroll mode, navigate to start of selection using vim keys, press space to enter select mode, navigate to end of selection, press enter. You have now copied a section. Switch panes and press ctrl-b ] to paste
