Group Think Idea: Everybody Download a demo of


of Reaper
Why you ask because

but really

i am using it on OSX right now and it’s fast and works really well
i am going to try to compile the linux/arm7 external for organelle when i get into the office during my lunch break

IF only for the amazing “tube_harmonics” & “far_modulator” effects this is cool

think of Gen~ but for pd? sounds amazing so far and clean --fingers crossed for a simple arm7 build later

digging it

beginning to drool

oh jesus


Will give some time to this!


That implementation of jsusfx does not support arm.
As a minimum your going to need to move to a newer version of del/eel, not sure if that will throw up any other issues or not - suck it and see I suppose :slight_smile:


I did not suck anything BTW.
It’s working. I am grateful the dude made a Makefile that actually made sense. I am going to transfer it over to Organelle and then i will gloat, until then we are still in devel


for those who want to test it out on OSX


It all works :slight_smile:

Now there are a few i am not particularly interested in [I have place a star next to ones i am

it compiles on arm?


I just tested with fx_formant and fx_reverb one from CERN and they sound really really clean


an almost direct conversion of the ambience plugin from mda, (sources found here), took an hour or so i guess. mostly for the experience, for the learning, and for having one more tool available for making audio and noises.


a delay effect, but instead of just overwriting the buffer every delay cycle, it (sort of) crossfades between the audio input and the buffered audio, and can create a blurred, mashed mix, and you can freeze input recording, so that the delay/buffer is static. assign your midi knobs to the parameters, and play around with, and fine-tune them in realtime.


another port/conversion, another reverb, this time from here. i did almost nothing here, as it was already a jesusonic plugin, but for the ‘original’ jesusonic. the channel-routing was a bit odd, and non-reaper specific, so i changed that to stereo (double mono).


slicey/dicey/cutup thingy. split and re-split slices, with some randomization and probabilities, everything (durations, start/end time, etc), synced (transport/tempo) to reaper, some initial inspiration from bbcut/livecut


boost + clip distortion. ugly and harsh.


same as fx_dist1, but input has been split in thee frequency bands, and distortion (boost/clip) is applied individually to each band.


compressor, based on loser’s js tutorial, then modified, tweaked, tried to learn and experiment with dynamics.


formant filter


experiment with a fractional-sample delay line and feedback. the delay length is ‘playable’ via midi, similar to a wavetable synth, and this was the first step towards the syn_plucked synth.


buffers incoming audio, then loops (forward or pingpong) small section of the buffer, optionally bypass recording, so that looped audio is static (‘freezed’). planned for realtime use.


my first (of many!) journey into glitch land, randomization, probabilities, … this one is very simple yet, but can creater some interesting cut-ups already.
preview1 (mp3, 429k), preview2 (mp3, 643k)
update 0.0.8: added pitch & stuttering efects, and ‘sliders’ for probabilities per step.
update v0.0.9: midi-controllable. hold midi keys, things are triggered at the next beat-start. notes from c2 -> e3 forces ‘on’ skip, reverse, mute, stutter, pitch. notes from c3 -> controls which slice of the buffer to play. randomization and probabilities can override the midi keys, so you might want to turn down the auto-random stuff if you plan to play/program via midi. experiment.

preliminary docs/info:

(already outdated. too many new things. new docs is planned, …ehmm…)

(will be done properly, when i have some time and motivation leftovers… doc writing isn’t as exciting as code-writing… :slight_smile:

the general idea is that audio is constantly being recorded into an internal buffer, and slices are randomly being played back from this, with some glitchy effects.

the length of the internal buffer is defined with “num beats”, and each beat is then sub-divided further with “num beat subdivs” (slices). every time the play position crosses into a new slice, something might get triggered, depending on probabilities.

[todo: describe ‘probabilities’]

there are 5 types of ‘effects’, or things that might happen, or 6 if you count ‘nothing’ as an effect…

skip - jumps randomly (“skip probability”) to somewhere else, to another step/sub-beat. max distance it can jump (from the play cursor) is defined by “skip max offset”.
reverse - playing backwards. note that the playback starts at the beginning of a slice, then playing backwards, into the previous slice.
mute - ‘silence’, nothing, mute
stutter - the slice is yet again subdivided, but only the first slice is repeatedly played (n-n-n-n-nineteen), number of slices is random, max number is maximum
pitch - plays the slice at another speed, no stretching or anything, just play-speed is temporarily modified. max pitch is how far from “play speed” it can go, from half speed (one octave down) to double (octave up)
each step/slice it can jump back to the rec cursor (play mode “sticky”) before selecting something new to do… so that the random stuff is small variations of the original audio only. or it can run “free” for no syncing.

and there’s a “global probability” slider for changing the general, randomness of the probabilities.
and a global playing speed

then, there’s the step sequencer, each step has a slider that control that step’s probs. so, totally there’s three things that is combined into one step-probability: global + effect + step-seq

finally, we have midi for realtime control.
the 5 ‘effects’ can be ‘forced’ with midi semi-notes c2…e2
or you can select slice to play with midi (semi-)notes from c3 and upwards.
hold midi key - probabilities etc are checked only when play/record cursor enters a new sub-beat, to keep everything in sync.

and, almost forgot, the triggers:
0 - clear step sequencer
1 - fill step seq with 1’s
2 - invert all steps

i guess it’s easier to understand by trying it

[todo: examples of usage, describe the ideas behind some parameters, how to use live/reltime, how to program, reaper example projects?]

i have noticed a few isues with this version, that i would like to fix, sometime…

  • clicks, clicks… some kind of anti-click things need to be in there, quite noticeable when doing play-speed changing things.
  • some not-planned things with midi control. when releasing a key, it doesn’t check which key, and this could create some weirdness if you play multiple keys rapidly after eachother, if not properly releasing eack key before pressing a new, the new slice will play, but if you release the first key while still holding the second, it will stop.


granular synthesis, or grain cloud… audio is buffered, lots of tiny sections of this buffer are looped and pitched and changed, etc, and then mixed/mashed


wavelet analysis (haar) of two inputs, then re-synthesis, crossfading/morphing between them. but, the main effect heard is the quality loss because of poor quality analysis/resynthesis. an experiment that didn’t go as planned, but perhaps we can do something else with the analysis results, before transforming them back to ‘proper’ audio. like fft-ish things.


simple midi, but controlled maknly via midi cc. made mainly for use with midi_automata.


modulation delay. ala phaser, flanger, for experimentation, various ways of combining the original, and modulated signal (add, sub, mul), and (failed, i think) attempt ot multiple taps/phases.


poor quality pitch shifter, replaying buffer at different speeds. nothing is done to get clean or good sounds from it. (again) based on loser’s tutorials


another first test, trying to make a reverb myself, a series of allpass filters, controllable via sliders, not tuned, doesn’t really sound like a reverb at all.


realtime sample, playback, overdub, erase, etc,… somewhat inspired by repeatler, but have plans for some other directions and features.

beats: buffersize, in beats
draw mode: how to draw the waveform. off, dots, lines.
sync mode: manual = play state manually toggled on/off with ‘transport note’ (below) manual, seq = sync to sequencer (reaper)
transport note: midi note to toggle transport on/off (if syncmode=manual)
record note: switch to record mode. records incoming audio into buffer
play note: switch to play mode. playback from buffer
erase note: …and same, but erase/clear buffer
bypass note: bypass mode

the record/play/erase/bypass modes are exclusive states (can only be in one of these modes), indicated by cursor color: red=record, green=play, blue=erase, white=bypass.



turns incoming audio into a square wave, on/off only, kind of 1-bit audio. and an additional filter to have a little bit of control.


switches between two audio inputs. control the toggling with a sync signal (f.ex with ana_transient or something), or with a specific midi note (for midi_automata, etc)


a simple tempo-synchronized delay, because i use them a lot.


very basic track things i always miss when in an experimental or ‘audio-journey’, go with the flow mood… so far, lowpass, highpass and boost. to be extended and finetuned.


lowpass filter. stumbled upon the formula by accident, when playing around with interpolation, and non-linear envelopes for the fx_kick. instead of using an incoming sample directly, we ‘travel towards it’, going just a small step towards it. kind of slowing down the fastest movements in the waveform. like a lowpass filter. quite simple to calculate (a plus, a minus, and a multply per sample, double for stereo), and a different way of looking at filtering.


That’s a lot of flippin ace sounding stuff. Fingers crossed it all works out swimmingly! So I already had Reaper and i run on Windows like a square, is this plugin installed as standard or do i need to fetch it from one of those links?


it’s their built in effects i assume – it’s all new to me all i know is that these plugins sound tight

mIdi is not supported so some do not work but like fx_glitch – it sounds cool but it’s MIDI controlled so it does not work but tons of the other ones work and because the spec is as such they play nice immediately --totally dope.
