Just for reference, how much cpu does the "harmonic oscillator" take up on the ER-301?

Not sure, I rarely checked CPU usage since I didn't have a problem with it :)

I sold mine a while back since I found my actual priorities were a bit different than I had planned for. I'd still say it was an excellent module and I learned a bit from implementing various things in it.

what about the i2c connection? is the process of connecting and mapping the 16n controller to it? I bought one a while ago on the chance that I might grab an ER-301 eventually

There's a whole thread on this over at the OD Discussion Forum, lots of good info!

Here it is!

totally works with the 16n by the way...

Remember that original er301 demo before it was released that sold all of us early adopters? I been thinking about that video and what originally drew me to the er301, back to the basics, simple audio scrubbing. It can do so much it’s easy to forget about this. So much fun, and sounds great on the 301. Two instances of it running here. What you see is the vocal track but I also have a piano sample track scrubbing as well on channel two!

This remains my main use for the module.

Niiice! :yay:
It can do a lot of interesting things, but I agree, audio scrubbing is probably one of the things it does best.

somehow i thought that the presets i made and samples i uploaded would be kept after the firmware update (as i remember it was like this when updating to jasmine?) - but now i lost everything when was booting v0.4 'fennel'. it's not a big deal as i see this like another chance to build better patches and to learn the machine more but i want to share the advice from the od-wiki:
Warning! There is a possibility that quicksaves and presets made with newer firmware versions are not backwards compatible. So to be safe you should make a copy of your ER-301/sc directory before switching firmware.

You didn't lose anything. Your old preset files are still on your SD card where you saved them. If you downgrade the firmware, you will see them again.

Here's a short explaination + jam of how I use the ER-301 in this mini system. I find it very inspiring to lay the basis of track while I'm away from my main system. I wanted to do it from scratch at first but it would probably have ended up being quite boring. Also, first try at recording my voice so I hope it isn't too cringey.

Nice sounds here !

Here’s a patch made with the ER-301 as the main sound source and effect. Additional voice is coming from Just Friends + Clouds and there’s also some Mimeophon :)

So it came to pass that the 301 got its 0.5 release, which allows you to use some ~20–30% more CPU power before buffer underruns occur (depending on the firmware variant). This is nice.

Here's a little example of how the er301 can be used for granular, similar to Clouds and Morphagene (x3!). In this patch i have a looper buffer feeding three manual grain units.
Each grain unit has individual control for level, pitch, grain length and trigger speed. Then also have a shared common control for position, these could all be cv controllable as well, by simply plugging cv into the sweet sixteen (passing the cv to the 301 via i2c, the faders become cv in attenuators for that input). Check out the vid, first you hear the incoming signal (rings) then I bring in the three manual grain units one at a time. basic patch, just showing what can be done.

Sweet! :party: gonna try to patch that up myself later.

Cool vids, brandonlogic.

I'm glad you included a bit of external modulation being converted, since I've been skeptical that it would work well. It seems to work well enough with a couple of channels, though I do still wonder how it would fare with more channels or closer-to-audio-rate signals.

I can tell you that its not suited for audio rate signals. once you get to 20hz you hear artifacts. Its best used for envelopes, lfos, stepped volts, gates and triggers, which is perfectly OK with me. there's sill plenty of inputs on the 301 itself that can handle audio rates just fine.
Its mostly a tactical controller, which is essential for the er301, giving it a playable interface. i look at it's cv inputs as a really nice bonus.

I put together a new mini system with once again the 301 as the brain : looper, delay, FX, filters. A mini Ableton Live. I love using it in this context.

By any chance would anyone know of a video which shows how to replace a panel of an ER-301?

Sorry if this may have been asked before but just couldn’t any links or thread on the topic. I have one on the way but have struggled to decide on the panel as they are all amazing.
Would be keen to see how hard it is to swap if I wanted to.

Yes: http://wiki.orthogonaldevices.com/index ... and_Repair

It's not difficult. I've had success with tongue pliers for the nuts (I duct taped their edges to avoid scratches). You'll need a wrench (or tongue plier works) and allen key for the rotary knob, that's easy to remove. You need to be very very careful with the screen though, if any piece of debris gets in their you will have a scratched screen - take it from my dumb experience.

Thanks for the tip. I had actually found that link but was hoping to stumble upon a video of some sorts. I’m ok with DIY but by far not a veteran - don’t want to screw up in the first week!
