Downward + Downward Beats

hello 301ers!
new double feature of custom units inspired by mixtur trautonium\subharmonicon & such… both are based on frequency dividers but one is an oscillator, the other a weird but cool rhythm generator.
everything is free to use with absolutely no limitations but as usual if you really really like them and would like to make a microdonation you can paypal me some change at hyena666@gmail.com
cheers!

Downward
00110012
Downard has a sine oscillator and 5 frequency divided square subharmonics.
controls

  • tune 1v/oct control of pitch
  • sine level control for the main sine oscillator
  • /2 to /6 level control for the 5 square subharmonics
  • lvl main output level
    cpu about 12%
    requires nothing
    tips you can insert an adsr envelope inside the lvl subchain to obtain a full voice. experiment with filters and for extra organic sound try an exact convolution with a very small IR (cello body or similar stuff, the internet is full of cool IR)

Downward Beats
00090010
The Beats version is a sequencer thougth for driving percussive instruments\samplers\drums\oneshots, but actually spits out stepped cv signals like a normal sequencer. Just insert it in the Gate subchain of a Sampler or use it on a global chain to trigger multiple events on your chains, or…use it to control pitch of oscillators or samplers, filter’s cutoff or whatever you want to modulate!
controls

  • clock insert your clock source here entering the clock subchain
  • int clk toggle button to activate an internal sine oscillator acting as embedded clock. when engaged it disables the external one and vice versa
  • f frequency of the internal clock in hertz.
  • main level of the main beat generator (same freq as clock)
  • /2 to /6 levels of the subdivisions of clock
  • scale this is an attenuator for the mixed gate signal. you can also use it to invert the phase of the gates.
  • offset a simple offset to fine tune the response of the gates.
    cpu about 17-20%
    requires Accents
    tips use scale and offset while you watch the custom unit display to “center” your gates and fine tune the results, keep in mind that the various subdivisions add up together, so it’s almost always necessary to tweak a bit the scale\offset parameter to get good triggering of your drums\percussions. Experiment with one of them at a time to get the feeling then start mixing just two of them and notice how they interact with one another, then go complex! a lot of lovely riddims are waiting for you!
    if you want to use it as pitch sequencer, keep in mind that the output is not quantized, so you better put a Scale Quantizer unit after it!

Hi Giona
then suggest to put one for each GATE present on a sample player (for example)?

This is a simple test

Thanks, emiliano

yes, you can use one single downward beats for each sample you have to trigger! of course if you have to trigger more than one its a bit cpu intensive…but if you make a patch with just sample players and downwards i think you can fairly manage three. i’ll give it a try and report how many can i load before maxxing out the cpu!
EDIT: just checked! 1 mono chain, three mono mix units each with one sample player triggered by a Downward Beats, all clocked by external clock put in a global chain = 76% cpu! i don’t think you’ll be able to use more than three but the result is very very cool! nice polyrhythms! i loaded 2 taiko samples and a metal sheet sample i recorded some years ago, sounds very nice! i have even some spare cpu to add a reverb or a delay!
EDIT 2: i’m so stupid…i just realized i didn’t say it in fact generates stepped cv’s, not really gates (because it mixes various low frequency square waves at different amplitudes) so it can be fully used as CV sequencer too! gonna update the documentation!

in this test three downward beats are triggering AND sequencing pitch of three different percussion sounds in stereo. cpu=about 80%

Hello @hyena, sorry to dig up this thread but I am experimenting with your downward beat unit. I am trying to build something with shared buffers from dub loopers, but cpu is not my best friend so I was looking for ways to simplify the unit.
I noticed that the divisions are made by a counter, followed by a comparator. Is there a big difference with using a tap tempo as clock divider instead of the counter + comparator? Still learning my way around the ER301, so analysing these patches is really helpful… Anyway, great unit, will share a jam one of these days…

by the way, is that PayPal address still active? I’ll buy you a coffee. Having great fun!

hey! first, thanks for your kind words and your interest in my units.
i think it is pretty fair to swap counter + comparator with a tap tempo unit, then using divisions in tap tempo to do frequency division. please try and tell me if you get a big improvement in cpu and if it behaves well!
and finally yes, the paypal is still on, no need to but if you want to offer a coffee you are very welcome and im grateful!
ciao! g.

Here’s a short part of a long jam using the Downward Beats as a sound effect (shared buffers with two dub loopers). Big fun! And indeed, it behaves as it should, and I save a couple of percentages in cpu. Had to adapt the gain a bit on the VCA after the tap tempo but that was it…

mate, this is really, really beautiful, i’m very glad one of my units helped you making this. if i close my eyes it’s not hard to imagine a butoh dance performance over it. your setup looks stellar too, i love the mixture of strange acoustic sources and all that processing. thanks for sharing this ! <3

Thanks for the kind words. And thanks for the inspiration! Just sent you a coffee. Cheers!

Really enjoyed this - very inspiring.

As it’s outputting CV I’m thinking as well as triggering the gate you can trigger a slice of the buffer or pitchshift the buffer using the same CV. You could share your live dub loop buffer with a variable speed player and mess with it there……not 100% sure but I think it’s possible depending on cpu :slight_smile:

Thanks! That means a lot coming from you. I’ve learned how to use my Er301 with examining your Autogen bundle.

Regarding the patch: you are describing exactly what I am doing already :slight_smile:
Two dub loopers, shared buffers with two varispeed players. Pitch and gates controlled by 2 downwards beat units. Divisions and “freeze” of the buffer adapter live. Still tweaking the unit, but once I’m happy I will gladly share it here!

(Looking for a way not to only pitch up, but also down occasionally)

Cheers

Ah brilliant! Glad you checked them out and that you are sharing buffers with other units. There’s lots of creative stuff that can be done on the er301. The Reels unit is also good for that.

Off topic a little - I’m using a script on Monome Norns / Grid called MLRE which is 6 loopers with independent pitch up / down / reverse etc per channel. It’s really great for the style of stuff in your video. It also includes lfo’s and pattern recorders.
mlre - Library - lines

Don’t have a Norns unfortunately. But I’m doing similar stuff with my assimil8or and cirklon as in the video. Great if you run out of CPU on the ER-301 :slight_smile:
