thanks Brian!

Thanks to Joe and Brian, I got the Looper to Player connection working. Unfortunately it doesn’t provide the functionality of some of the loopers I’m used to working with.
Adding the Player after the looper and sharing the same buffer is a neat trick but changes you make to the player (speed, direction, etc) can only effect what’s playing in the looper. You can’t for example, reverse direction, record an over dub while reversed (negative speed) then change direction again.
This type of hardware looping functionality has been around for a long time. I kinda expected this ability in at least one of the loopers.

My brain is hurting now because I’m trying to figure out a way to do this… add another looper at the end somehow?..

You can change the speed on the Player to -1 and you got a reverse playback of your buffer :slight_smile:

Yea, but you can’t record in reverse… see? I think you missed my point. Whatever overdubs you make will all be effected in the same way because the player can only alter what’s in the buffer. In a typical looper you change the pitch and direction of what’s going INTO the buffer. Maybe I’m not explaining that correctly but think of the functionality you have in hardware loopers like the Echoplex Digital Pro, Boss RC-50, and many others.

The loopers in the 301 need to have the ability to record overdubs at different speeds and directions. Somehow combine the present loopers with the variable player to get this functionality?. :roll_eyes:

See that? just getting started and already have a feature request!. :grin:

I can live with the player doing the reverse and pitch stuff. But in the feature requests section under “very likely” is this:

Looping

  • layering looper (see thread)
  • variable speed recording
  • pedal Looper > double loop length
  • speed control
  • more monitoring options
  • reverse
  • half speed
  • loop volume level
  • option to begin overdubbing immediately after first record pass.

BUT-> when buying the ER 301 you must have seen the warning that this is a product still in development, so in my opinion, if you need funktionality like RC 50 or Echoplex, get one of those boxes where the features are already there. Brian is doing the development of the ER 301 at his pace and inspiration and I am very happy with his style of doing it…

Wow! Thank you for pointing that out. I wasn’t aware this was “very likely” that’s great.
I already have those boxes (Echoplex, RC-50) but obviously I’m looking for a Eurorack solution with the 301. I was aware of the product development situation when I bought the 301, no regrets here. I’ve had it for about a year now and I actually thought about selling it at one point but once I started to realize how powerful it is, I decided to stick with it and continue to study.

I am retired now from a long career in electronics manufacturing and engineering so I certainly appreciate the hard work and long hours Brian has put into the module.

HELP! HELP! HELP!..

Is there any content in the “LIB” folder on the SD card by default? If so, I think I just deleted it! :grimacing:
I mean, when a new 301 is shipped from Brian, is there anything in this folder?
…and how to get it back… ugh

Nope. The only files in lib are the ones you put there.

Thanks Brian!

I have a question about CPU load, as i’m building a live set almost only on the ER301, i hope is okay to write in this topic:
It’s normal that the CPU doesn’t go down till 3% when i bypass all the mixers/units, but remains in a range that goes high proportionally to the number of the mixers/units loaded?

Let’s say if i have 4 mixer with respectively few audio units inside everyone (singlecycle/variablespeed player/fm oscillators) and 4 delays for each unit the CPU% is near 65%, when i bypass every single thing in the chain the CPU% drops down till 12% and not to 3% , and if i add more mixers/units, more or less with the same amount of CPU% of the first four (after bypassing the others of course), if bypass everything in the module after that, the CPU% drops down to 28% and no more to 12%, and so on…

In a few words, more units i put inside, more the CPU remains up even with everything bypassed.
It’s a normal behaviour?
Of course if i delete the units the cpu drops to 3%, so maybe it’s normal that even with all bypassed the % doesn’t go down.

I reported the same issue in the “live environments” thread… I’ll go bump it…

So I’ve just ordered a 301 (very excited!) and I’m wondering if i2c headers are already installed/ready to go on the module? Thanks, and sorry if this has been covered elsewhere, I’ve been a little overwhelmed trying to grasp as much as I can before the module arrives.

If you ordered it new they should be ready to go.

I’ve been making a drum kit of sorts lately on the 301, based on single cycle waveforms. If I were to share this drum kit as a preset - how would I best share/include the waveforms needed to use the kit? Do the paths to the files need to be accurate, or is it enough to load the set of files from wherever on your SD card? I’ve read that package-sharing is planned for the future (looking much forward to that), but what’s the best way to do this now when you’re using external files you need to provide? :slight_smile:

I think whoever is using it would need to have the files in the same directory with the same name as you have them, so you’d probably just want to explain how to set that up when you share the patch.

Ok, cheers - good to know! :slight_smile:

Hi everyone! I’m also very new to the ER-301 and haven’t figured out yet how to send a signal into e.g. two 3-eq chains. One mutes the mid and highs the second mutes the lows and is followed by a delay for example. So that i can process sounds in certain frequencies etc. and leave other frequencies untouched.

Use the 2-band unit. Each band receives the input and the output of all bands are mixed to unity.

What are you people using the G inputs for (top left)? Can they be utilized for anything else other than gates/trigs??

They are also good for external envelopes, or anything you want to use the positive parts of, I.e. it cuts everything below zero.
And since those inputs aren’t calibrated they won’t work well for v/oct pitch cv…
I mostly use them for different clocks and gates though.
